// JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes.
// Has several variations in 1978, 1983, 1990 and 1997.
// JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
// JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
// 2 planes, first is superset of 0208, second - revised 0212.
// Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
// Byte encodings are:
// * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
// encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
// Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
// * EUC-JP: Up to 3 bytes per character. Used mostly on *nixes.
// 0x00-0x7F - lower part of 0201
// 0x8E, 0xA1-0xDF - upper part of 0201
// (0xA1-0xFE)x2 - 0208 plane (94x94).
// 0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
// * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
// Used as-is in ISO2022 family.
// * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII,
// 0201-1976 Roman, 0208-1978, 0208-1983.
// * ISO2022-JP-1: Adds esc seq for 0212-1990.
// * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
// * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
// * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
//
// After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

// There are lots of tables for Big5 and cp950. Please see the following links for history:
// http://moztw.org/docs/big5/ http://www.haible.de/bruno/charsets/conversion-tables/Big5.html
// Variations, in roughly number of defined chars:
// * Windows CP 950: Microsoft variant of Big5. Canonical: http://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP950.TXT
// * Windows CP 951: Microsoft variant of Big5-HKSCS-2001. Seems to be never public. http://me.abelcheung.org/articles/research/what-is-cp951/
// * Big5-2003 (Taiwan standard) almost superset of cp950.
// * Unicode-at-on (UAO) / Mozilla 1.8. Falling out of use on the Web. Not supported by other browsers.
// * Big5-HKSCS (-2001, -2004, -2008). Hong Kong standard.
// many unicode code points moved from PUA to Supplementary plane (U+2XXXX) over the years.
// Plus, it has 4 combining sequences.
// Seems that Mozilla refused to support it for 10 yrs. https://bugzilla.mozilla.org/show_bug.cgi?id=162431 https://bugzilla.mozilla.org/show_bug.cgi?id=310299
// because big5-hkscs is the only encoding to include astral characters in non-algorithmic way.
// Implementations are not consistent within browsers; sometimes labeled as just big5.
// MS Internet Explorer switches from big5 to big5-hkscs when a patch applied.
// Great discussion & recap of what's going on https://bugzilla.mozilla.org/show_bug.cgi?id=912470#c31
// In the encoder, it might make sense to support encoding old PUA mappings to Big5 bytes seq-s.
// Official spec: http://www.ogcio.gov.hk/en/business/tech_promotion/ccli/terms/doc/2003cmp_2008.txt
// http://www.ogcio.gov.hk/tc/business/tech_promotion/ccli/terms/doc/hkscs-2008-big5-iso.txt
//
// Current understanding of how to deal with Big5(-HKSCS) is in the Encoding Standard, http://encoding.spec.whatwg.org/#big5-encoder
// Unicode mapping (http://www.unicode.org/Public/MAPPINGS/OBSOLETE/EASTASIA/OTHER/BIG5.TXT) is said to be wrong.

* [`checkHyphens`](#checkHyphens)
* [`checkJoiners`](#checkJoiners)
* [`processingOption`](#processingOption)
* [`useSTD3ASCIIRules`](#useSTD3ASCIIRules)
* [`verifyDNSLength`](#verifyDNSLength)
### `toUnicode(domainName[, options])`
Converts a case-folded Punycode string of ASCII symbols to a string of Unicode symbols.
Available options:
* [`checkBidi`](#checkBidi)
* [`checkHyphens`](#checkHyphens)
* [`checkJoiners`](#checkJoiners)
* [`processingOption`](#processingOption)
* [`useSTD3ASCIIRules`](#useSTD3ASCIIRules)
## Options
### `checkBidi`
Type: `Boolean`
Default value: `false`
When set to `true`, any bi-directional text within the input will be checked for validation.
### `checkHyphens`
Type: `Boolean`
Default value: `false`
When set to `true`, the positions of any hyphen characters within the input will be checked for validation.
### `checkJoiners`
Type: `Boolean`
Default value: `false`
When set to `true`, any word joiner characters within the input will be checked for validation.
### `processingOption`
Type: `String`
Default value: `"nontransitional"`
When set to `"transitional"`, symbols within the input will be validated according to the older IDNA2003 protocol. When set to `"nontransitional"`, the current IDNA2008 protocol will be used.
### `useSTD3ASCIIRules`
Type: `Boolean`
Default value: `false`
When set to `true`, input will be validated according to [STD3 Rules](http://unicode.org/reports/tr46/#STD3_Rules).

# Stealthy-Require
[](https://travis-ci.org/analog-nico/stealthy-require)
[](https://coveralls.io/r/analog-nico/stealthy-require)
[](https://david-dm.org/analog-nico/stealthy-require)
This is probably the closest you can currently get to require something in node.js with completely bypassing the require cache.
`stealthy-require` works like this:
1. It clears the require cache.
2. It calls a callback in which you require your module(s) without the cache kicking in.
3. It clears the cache again and restores its old state.
The restrictions are:
- [Native modules cannot be required twice.](https://github.com/nodejs/node/issues/5016) Thus this module bypasses the require cache only for non-native (e.g. JS) modules.
- The require cache is only bypassed for all operations that happen synchronously when a module is required. If a module lazy loads another module at a later time that require call will not bypass the cache anymore.
This means you should have a close look at all internal require calls before you decide to use this library.
## Installation
[](https://npmjs.org/package/stealthy-require)
This is a module for node.js and is installed via npm:
``` bash
npm install stealthy-require --save
```
## Usage
Let's say you want to bypass the require cache for this require call:
``` js
var request = require('request');
```
With `stealthy-require` you can do that like this:
``` js
var stealthyRequire = require('stealthy-require');
var requestFresh = stealthyRequire(require.cache, function () {
return require('request');
});
```
The require cache is bypassed for the module you require (i.e. `request`) as well as all modules the module requires (i.e. `http` and many more).
Sometimes the require cache shall not be bypassed for specific modules. E.g. `request` is required but `tough-cookie` – on which `request` depends on – shall be required using the regular cache. For that you can pass two extra arguments to `stealthyRequire(...)`:
- A callback that requires the modules that shall be required without bypassing the cache
- The `module` variable
``` js
var stealthyRequire = require('stealthy-require');
var requestFresh = stealthyRequire(require.cache, function () {
return require('request');
},
function () {
require('tough-cookie'); // No return needed
// You can require multiple modules here
}, module);
```
## Usage with Module Bundlers
- [Webpack](https://webpack.github.io) works out-of-the-box like described in the [Usage section](#usage) above.
- [Browserify](http://browserify.org) does not expose `require.cache`. However, as of `[email protected]` the cache is passed as the 6th argument to CommonJS modules. Thus you can pass this argument instead:
``` js
// Tweak for Browserify - using arguments[5] instead of require.cache
var requestFresh = stealthyRequire(arguments[5], function () {
return require('request');
});
```
## Preventing a Memory Leak When Repeatedly Requiring Fresh Module Instances in Node.js
If you are using `stealthy-require` in node.js and repeatedly require fresh module instances the `module.children` array will hold all module instances which prevents unneeded instances to be garbage collected.
Assume your code calls `doSomething()` repeatedly.
``` js
var stealthyRequire = require('stealthy-require');
function doSomething() {
var freshInstance = stealthyRequire(require.cache, function () {
return require('some-module');
});
return freshInstance.calc();
}
```
After `doSomething()` returns `freshInstance` is not used anymore but won’t be garbage collected because `module.children` still holds a reference. The solution is to truncate `module.children` accordingly:
``` js
var stealthyRequire = require('stealthy-require');
function doSomething() {
var initialChildren = module.children.slice(); // Creates a shallow copy of the array
var freshInstance = stealthyRequire(require.cache, function () {
return require('some-module');
});
module.children = initialChildren;
return freshInstance.calc();
}
```
The `slice` operation removes all new `module.children` entries created during the `stealthyRequire(...)` call and thus `freshInstance` gets garbage collected after `doSomething()` returns.
## Technical Walkthrough
``` js
// 1. Load stealthy-require
var stealthyRequire = require('stealthy-require');
// This does nothing but loading the code.
// It has no side-effects like patching the module loader or anything.
// Any regular require works as always.
var request1 = require('request');
// 2. Call stealthyRequire with passing the require cache and a callback.
var requestFresh = stealthyRequire(require.cache, function () {
// 2a. Before this callback gets called the require cache is cleared.
// 2b. Any require taking place here takes place on a clean require cache.
// Since the require call is part of the user's code it also works with module bundlers.
return require('request');
// Anything returned here will be returned by stealthyRequire(...).
// 2c. After this callback gets called the require cache is
// - cleared again and
// - restored to its old state before step 2.
});
// Any regular require again works as always.
// In this case require returns the cached request module instance.
var request2 = require('request');
// And voilà:
request1 === request2 // -> true
request1 === requestFresh // -> false
```
## Contributing
To set up your development environment for `stealthy-require`:
1. Clone this repo to your desktop,
2. in the shell `cd` to the main folder,
3. hit `npm install`,
4. hit `npm install gulp -g` if you haven't installed gulp globally yet, and
5. run `gulp dev`. (Or run `node ./node_modules/.bin/gulp dev` if you don't want to install gulp globally.)
`gulp dev` watches all source files and if you save some changes it will lint the code and execute all tests. The test coverage report can be viewed from `./coverage/lcov-report/index.html`.
If you want to debug a test you should use `gulp test-without-coverage` to run all tests without obscuring the code by the test coverage instrumentation.
## Change History
- v1.1.1 (2017-05-08)

- v1.1.0 (2017-04-25)
- Added ability to disable bypassing the cache for certain modules *(Thanks to @novemberborn for suggesting this in [issue #3](https://github.com/analog-nico/stealthy-require/issues/3))*
- Added section in README about a [potential memory leak](#preventing-a-memory-leak-when-repeatedly-requiring-fresh-module-instances-in-nodejs) *(Thanks to @Flarna and @novemberborn for bringing that up in [issue #2](https://github.com/analog-nico/stealthy-require/issues/2))*
- Performance optimizations *(Thanks to @jcready for [pull request #1](https://github.com/analog-nico/stealthy-require/pull/1))*
- v1.0.0 (2016-07-18)
- **Breaking Change:** API completely changed. Please read the [Usage section](#usage) again.
- Redesigned library to support module bundlers like [Webpack](https://webpack.github.io) and [Browserify](http://browserify.org)
- v0.1.0 (2016-05-26)
- Initial version

The ultimate javascript content-type utility.
Similar to [the `[email protected]` module](https://www.npmjs.com/package/mime), except:
- __No fallbacks.__ Instead of naively returning the first available type,
`mime-types` simply returns `false`, so do
`var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
- No `.define()` functionality
- Bug fixes for `.lookup(path)`
Otherwise, the API is compatible with `mime` 1.x.
## Install
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install mime-types
```
## Adding Types
All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
so open a PR there if you'd like to add mime types.
## API
<!-- eslint-disable no-unused-vars -->
```js
var mime = require('mime-types')
```
All functions return `false` if input is invalid or not found.
### mime.lookup(path)
Lookup the content-type associated with a file.
<!-- eslint-disable no-undef -->
```js
mime.lookup('json') // 'application/json'
mime.lookup('.md') // 'text/markdown'
mime.lookup('file.html') // 'text/html'
mime.lookup('folder/file.js') // 'application/javascript'
mime.lookup('folder/.htaccess') // false
mime.lookup('cats') // false
```
### mime.contentType(type)
Create a full content-type header given a content-type or extension.
When given an extension, `mime.lookup` is used to get the matching
content-type, otherwise the given content-type is used. Then if the
content-type does not already have a `charset` parameter, `mime.charset`
is used to get the default charset and add to the returned content-type.
<!-- eslint-disable no-undef -->
```js
mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
mime.contentType('file.json') // 'application/json; charset=utf-8'
mime.contentType('text/html') // 'text/html; charset=utf-8'
mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
// from a full path
mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
```
### mime.extension(type)
Get the default extension for a content-type.
<!-- eslint-disable no-undef -->
```js
mime.extension('application/octet-stream') // 'bin'
```
### mime.charset(type)
Lookup the implied default charset of a content-type.
<!-- eslint-disable no-undef -->
```js
mime.charset('text/markdown') // 'UTF-8'
```
### var type = mime.types[extension]
A map of content-types by extension.
### [extensions...] = mime.extensions[type]
A map of extensions by content-type.

# abab [](https://www.npmjs.com/package/abab) [](https://travis-ci.org/jsdom/abab)
A JavaScript module that implements `window.atob` and `window.btoa` according the forgiving-base64 algorithm in the [Infra Standard](https://infra.spec.whatwg.org/#forgiving-base64). The original code was forked from [w3c/web-platform-tests](https://github.com/w3c/web-platform-tests/blob/master/html/webappapis/atob/base64.html).
Compatibility: Node.js version 3+ and all major browsers.
Install with `npm`:
```sh
npm install abab
```
## API
### `btoa` (base64 encode)
```js
const { btoa } = require('abab');
btoa('Hello, world!'); // 'SGVsbG8sIHdvcmxkIQ=='
```
### `atob` (base64 decode)
```js
const { atob } = require('abab');
atob('SGVsbG8sIHdvcmxkIQ=='); // 'Hello, world!'
```
#### Valid characters
[Per the spec](https://html.spec.whatwg.org/multipage/webappapis.html#atob:dom-windowbase64-btoa-3), `btoa` will accept strings "containing only characters in the range `U+0000` to `U+00FF`." If passed a string with characters above `U+00FF`, `btoa` will return `null`. If `atob` is passed a string that is not base64-valid, it will also return `null`. In both cases when `null` is returned, the spec calls for throwing a `DOMException` of type `InvalidCharacterError`.

If you want to include just one of the methods to save bytes in your client-side code, you can `require` the desired module directly.
```js
const atob = require('abab/lib/atob');
const btoa = require('abab/lib/btoa');
```

### Checklists
If you're **submitting a PR** or **deploying to npm**, please use the [checklists in CONTRIBUTING.md](https://github.com/jsdom/abab/blob/master/CONTRIBUTING.md#checklists)
### Remembering `atob` vs. `btoa`
Here's a mnemonic that might be useful: if you have a plain string and want to base64 encode it, then decode it, `btoa` is what you run before (**b**efore - **b**toa), and `atob` is what you run after (**a**fter - **a**tob).

# Deprecated!
As of Feb 11th 2020, request is fully deprecated. No new changes are expected land. In fact, none have landed for some time.
For more information about why request is deprecated and possible alternatives refer to
[this issue](https://github.com/request/request/issues/3142).

## Super simple to use
Request is designed to be the simplest way possible to make http calls. It supports HTTPS and follows redirects by default.
```js
const request = require('request');
request('http://www.google.com', function (error, response, body) {
console.error('error:', error); // Print the error if one occurred
console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
console.log('body:', body); // Print the HTML for the Google homepage.
});
```

Request also offers [convenience methods](#convenience-methods) like

lots of [usage examples](#examples) and several
[debugging techniques](#debugging).
---
## Streaming
You can stream any response to a file stream.
```js
request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
```
You can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).
```js
fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))
```
Request can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.
```js
request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))
```
Request emits a "response" event when a response is received. The `response` argument will be an instance of [http.IncomingMessage](https://nodejs.org/api/http.html#http_class_http_incomingmessage).
```js
request
.get('http://google.com/img.png')
.on('response', function(response) {
console.log(response.statusCode) // 200
console.log(response.headers['content-type']) // 'image/png'
})
.pipe(request.put('http://mysite.com/img.png'))
```
To easily handle errors when streaming requests, listen to the `error` event before piping:
```js
request
.get('http://mysite.com/doodle.png')
.on('error', function(err) {
console.error(err)
})
.pipe(fs.createWriteStream('doodle.png'))
```
Now let’s get fancy.
```js
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
if (req.method === 'PUT') {
req.pipe(request.put('http://mysite.com/doodle.png'))
} else if (req.method === 'GET' || req.method === 'HEAD') {
request.get('http://mysite.com/doodle.png').pipe(resp)
}
}
})
```
You can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:
```js
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
const x = request('http://mysite.com/doodle.png')
req.pipe(x)
x.pipe(resp)
}
})
```
And since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)
```js
req.pipe(request('http://mysite.com/doodle.png')).pipe(resp)
```
Also, none of this new functionality conflicts with requests previous features, it just expands them.
```js
const r = request.defaults({'proxy':'http://localproxy.com'})
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
r.get('http://google.com/doodle.png').pipe(resp)
}
})
```
You can still use intermediate proxies, the requests will still follow HTTP forwards, etc.

## Promises & Async/Await
`request` supports both streaming and callback interfaces natively. If you'd like `request` to return a Promise instead, you can use an alternative interface wrapper for `request`. These wrappers can be useful if you prefer to work with Promises, or if you'd like to use `async`/`await` in ES2017.
Several alternative interfaces are provided by the request team, including:
- [`request-promise`](https://github.com/request/request-promise) (uses [Bluebird](https://github.com/petkaantonov/bluebird) Promises)
- [`request-promise-native`](https://github.com/request/request-promise-native) (uses native Promises)
- [`request-promise-any`](https://github.com/request/request-promise-any) (uses [any-promise](https://www.npmjs.com/package/any-promise) Promises)
Also, [`util.promisify`](https://nodejs.org/api/util.html#util_util_promisify_original), which is available from Node.js v8.0 can be used to convert a regular function that takes a callback to return a promise instead.

## Forms
`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.
#### application/x-www-form-urlencoded (URL-Encoded Forms)
URL-encoded forms are simple.
```js
request.post('http://service.com/upload', {form:{key:'value'}})
// or
request.post('http://service.com/upload').form({key:'value'})
// or
request.post({url:'http://service.com/upload', form: {key:'value'}}, function(err,httpResponse,body){ /* ... */ })
```
#### multipart/form-data (Multipart Form Uploads)
For `multipart/form-data` we use the [form-data](https://github.com/form-data/form-data) library by [@felixge](https://github.com/felixge). For the most cases, you can pass your upload form data via the `formData` option.
```js
const formData = {
// Pass a simple key-value pair
my_field: 'my_value',
// Pass data via Buffers
my_buffer: Buffer.from([1, 2, 3]),
// Pass data via Streams
my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
// Pass multiple values /w an Array
attachments: [
fs.createReadStream(__dirname + '/attachment1.jpg'),
fs.createReadStream(__dirname + '/attachment2.jpg')
],
// Pass optional meta-data with an 'options' object with style: {value: DATA, options: OPTIONS}
// Use case: for some types of streams, you'll need to provide "file"-related information manually.
// See the `form-data` README for more information about options: https://github.com/form-data/form-data
custom_file: {
value: fs.createReadStream('/dev/urandom'),
options: {
filename: 'topsecret.jpg',
contentType: 'image/jpeg'
}
}
};
request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) {
if (err) {
return console.error('upload failed:', err);
}
console.log('Upload successful! Server responded with:', body);
});
```
For advanced cases, you can access the form-data object itself via `r.form()`. This can be modified until the request is fired on the next cycle of the event-loop. (Note that this calling `form()` will clear the currently set form data for that request.)
```js
// NOTE: Advanced use-case, for normal use see 'formData' usage above
const r = request.post('http://service.com/upload', function optionalCallback(err, httpResponse, body) {...})
const form = r.form();
form.append('my_field', 'my_value');
form.append('my_buffer', Buffer.from([1, 2, 3]));
form.append('custom_file', fs.createReadStream(__dirname + '/unicycle.jpg'), {filename: 'unicycle.jpg'});
```
See the [form-data README](https://github.com/form-data/form-data) for more information & examples.
#### multipart/related
Some variations in different HTTP implementations require a newline/CRLF before, after, or both before and after the boundary of a `multipart/related` request (using the multipart option). This has been observed in the .NET WebAPI version 4.0. You can turn on a boundary preambleCRLF or postamble by passing them as `true` to your request options.
```js
request({
method: 'PUT',
preambleCRLF: true,
postambleCRLF: true,
uri: 'http://service.com/upload',
multipart: [
{
'content-type': 'application/json',
body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
},
{ body: 'I am an attachment' },
{ body: fs.createReadStream('image.png') }
],
// alternatively pass an object containing additional options
multipart: {
chunked: false,
data: [
{
'content-type': 'application/json',
body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
},
{ body: 'I am an attachment' }
]
}
},
function (error, response, body) {
if (error) {
return console.error('upload failed:', error);
}
console.log('Upload successful! Server responded with:', body);
})
```
[back to top](#table-of-contents)
---
## HTTP Authentication
```js
request.get('http://some.server.com/').auth('username', 'password', false);
// or
request.get('http://some.server.com/', {
'auth': {
'user': 'username',
'pass': 'password',
'sendImmediately': false
}
});
// or
request.get('http://some.server.com/').auth(null, null, true, 'bearerToken');
// or
request.get('http://some.server.com/', {
'auth': {
'bearer': 'bearerToken'
}
});
```
If passed as an option, `auth` should be a hash containing values:
- `user` || `username`
- `pass` || `password`
- `sendImmediately` (optional)
- `bearer` (optional)
The method form takes parameters
`auth(username, password, sendImmediately, bearer)`.
`sendImmediately` defaults to `true`, which causes a basic or bearer
authentication header to be sent. If `sendImmediately` is `false`, then
`request` will retry with a proper authentication header after receiving a
`401` response from the server (which must contain a `WWW-Authenticate` header
indicating the required authentication method).
Note that you can also specify basic authentication using the URL itself, as
detailed in [RFC 1738](http://www.ietf.org/rfc/rfc1738.txt). Simply pass the
`user:password` before the host with an `@` sign:
```js
const username = 'username',
password = 'password',
url = 'http://' + username + ':' + password + '@some.server.com';
request({url}, function (error, response, body) {
// Do more stuff with 'body' here
});
```
Digest authentication is supported, but it only works with `sendImmediately`
set to `false`; otherwise `request` will send basic authentication on the
initial request, which will probably cause the request to fail.
Bearer authentication is supported, and is activated when the `bearer` value is
available. The value may be either a `String` or a `Function` returning a
`String`. Using a function to supply the bearer token is particularly useful if
used in conjunction with `defaults` to allow a single function to supply the
last known token at the time of sending a request, or to compute one on the fly.

## Custom HTTP Headers
HTTP Headers, such as `User-Agent`, can be set in the `options` object.
In the example below, we call the github API to find out the number
of stars and forks for the request repository. This requires a
custom `User-Agent` header as well as https.
```js
const request = require('request');
const options = {
url: 'https://api.github.com/repos/request/request',
headers: {
'User-Agent': 'request'
}
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
const info = JSON.parse(body);
console.log(info.stargazers_count + " Stars");
console.log(info.forks_count + " Forks");
}
}
request(options, callback);
```

## OAuth Signing
[OAuth version 1.0](https://tools.ietf.org/html/rfc5849) is supported. The
default signing algorithm is
[HMAC-SHA1](https://tools.ietf.org/html/rfc5849#section-3.4.2):
```js
// OAuth1.0 - 3-legged server side flow (Twitter example)
// step 1
const qs = require('querystring')
, oauth =
{ callback: 'http://mysite.com/callback/'
, consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
}
, url = 'https://api.twitter.com/oauth/request_token'
;
request.post({url:url, oauth:oauth}, function (e, r, body) {
// Ideally, you would take the body in the response
// and construct a URL that a user clicks on (like a sign in button).
// The verifier is only available in the response after a user has
// verified with twitter that they are authorizing your app.
// step 2
const req_data = qs.parse(body)
const uri = 'https://api.twitter.com/oauth/authenticate'
+ '?' + qs.stringify({oauth_token: req_data.oauth_token})
// redirect the user to the authorize uri
// step 3
// after the user is redirected back to your server
const auth_data = qs.parse(body)
, oauth =
{ consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
, token: auth_data.oauth_token
, token_secret: req_data.oauth_token_secret
, verifier: auth_data.oauth_verifier
}
, url = 'https://api.twitter.com/oauth/access_token'
;
request.post({url:url, oauth:oauth}, function (e, r, body) {
// ready to make signed requests on behalf of the user
const perm_data = qs.parse(body)
, oauth =
{ consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
, token: perm_data.oauth_token
, token_secret: perm_data.oauth_token_secret
}
, url = 'https://api.twitter.com/1.1/users/show.json'
, qs =
{ screen_name: perm_data.screen_name
, user_id: perm_data.user_id
}
;
request.get({url:url, oauth:oauth, qs:qs, json:true}, function (e, r, user) {
console.log(user)
})
})
})
```
For [RSA-SHA1 signing](https://tools.ietf.org/html/rfc5849#section-3.4.3), make
the following changes to the OAuth options object:
* Pass `signature_method : 'RSA-SHA1'`
* Instead of `consumer_secret`, specify a `private_key` string in
[PEM format](http://how2ssl.com/articles/working_with_pem_files/)
For [PLAINTEXT signing](http://oauth.net/core/1.0/#anchor22), make
the following changes to the OAuth options object:
* Pass `signature_method : 'PLAINTEXT'`
To send OAuth parameters via query params or in a post body as described in The
[Consumer Request Parameters](http://oauth.net/core/1.0/#consumer_req_param)
section of the oauth1 spec:
* Pass `transport_method : 'query'` or `transport_method : 'body'` in the OAuth
options object.
* `transport_method` defaults to `'header'`
To use [Request Body Hash](https://oauth.googlecode.com/svn/spec/ext/body_hash/1.0/oauth-bodyhash.html) you can either
* Manually generate the body hash and pass it as a string `body_hash: '...'`
* Automatically generate the body hash by passing `body_hash: true`

---
## Proxies
If you specify a `proxy` option, then the request (and any subsequent
redirects) will be sent via a connection to the proxy server.
If your endpoint is an `https` url, and you are using a proxy, then
request will send a `CONNECT` request to the proxy server *first*, and
then use the supplied connection to connect to the endpoint.
That is, first it will make a request like:
```
HTTP/1.1 CONNECT endpoint-server.com:80
Host: proxy-server.com
User-Agent: whatever user agent you specify
```
and then the proxy server make a TCP connection to `endpoint-server`
on port `80`, and return a response that looks like:
```
HTTP/1.1 200 OK
```
At this point, the connection is left open, and the client is
communicating directly with the `endpoint-server.com` machine.
See [the wikipedia page on HTTP Tunneling](https://en.wikipedia.org/wiki/HTTP_tunnel)
for more information.
By default, when proxying `http` traffic, request will simply make a
standard proxied `http` request. This is done by making the `url`
section of the initial line of the request a fully qualified url to
the endpoint.
For example, it will make a single request that looks like:
```
HTTP/1.1 GET http://endpoint-server.com/some-url
Host: proxy-server.com
Other-Headers: all go here
request body or whatever
```
Because a pure "http over http" tunnel offers no additional security
or other features, it is generally simpler to go with a
straightforward HTTP proxy in this case. However, if you would like
to force a tunneling proxy, you may set the `tunnel` option to `true`.
You can also make a standard proxied `http` request by explicitly setting
`tunnel : false`, but **note that this will allow the proxy to see the traffic
to/from the destination server**.
If you are using a tunneling proxy, you may set the
`proxyHeaderWhiteList` to share certain headers with the proxy.
You can also set the `proxyHeaderExclusiveList` to share certain
headers only with the proxy and not with destination host.
By default, this set is:
```
accept
accept-charset
accept-encoding
accept-language
accept-ranges
cache-control
content-encoding
content-language
content-length
content-location
content-md5
content-range
content-type
connection
date
expect
max-forwards
pragma
proxy-authorization
referer
te
transfer-encoding
user-agent
via
```
Note that, when using a tunneling proxy, the `proxy-authorization`
header and any headers from custom `proxyHeaderExclusiveList` are
*never* sent to the endpoint server, but only to the proxy server.
### Controlling proxy behaviour using environment variables
The following environment variables are respected by `request`:
* `HTTP_PROXY` / `http_proxy`
* `HTTPS_PROXY` / `https_proxy`
* `NO_PROXY` / `no_proxy`
When `HTTP_PROXY` / `http_proxy` are set, they will be used to proxy non-SSL requests that do not have an explicit `proxy` configuration option present. Similarly, `HTTPS_PROXY` / `https_proxy` will be respected for SSL requests that do not have an explicit `proxy` configuration option. It is valid to define a proxy in one of the environment variables, but then override it for a specific request, using the `proxy` configuration option. Furthermore, the `proxy` configuration option can be explicitly set to false / null to opt out of proxying altogether for that request.
`request` is also aware of the `NO_PROXY`/`no_proxy` environment variables. These variables provide a granular way to opt out of proxying, on a per-host basis. It should contain a comma separated list of hosts to opt out of proxying. It is also possible to opt of proxying when a particular destination port is used. Finally, the variable may be set to `*` to opt out of the implicit proxy configuration of the other environment variables.
Here's some examples of valid `no_proxy` values:
* `google.com` - don't proxy HTTP/HTTPS requests to Google.
* `google.com:443` - don't proxy HTTPS requests to Google, but *do* proxy HTTP requests to Google.
* `google.com:443, yahoo.com:80` - don't proxy HTTPS requests to Google, and don't proxy HTTP requests to Yahoo!
* `*` - ignore `https_proxy`/`http_proxy` environment variables altogether.

## UNIX Domain Sockets
`request` supports making requests to [UNIX Domain Sockets](https://en.wikipedia.org/wiki/Unix_domain_socket). To make one, use the following URL scheme:
```js
/* Pattern */ 'http://unix:SOCKET:PATH'
/* Example */ request.get('http://unix:/absolute/path/to/unix.socket:/request/path')
```
Note: The `SOCKET` path is assumed to be absolute to the root of the host file system.

## TLS/SSL Protocol
TLS/SSL Protocol options, such as `cert`, `key` and `passphrase`, can be
set directly in `options` object, in the `agentOptions` property of the `options` object, or even in `https.globalAgent.options`. Keep in mind that, although `agentOptions` allows for a slightly wider range of configurations, the recommended way is via `options` object directly, as using `agentOptions` or `https.globalAgent.options` would not be applied in the same way in proxied environments (as data travels through a TLS connection instead of an http/https agent).
```js
const fs = require('fs')
, path = require('path')
, certFile = path.resolve(__dirname, 'ssl/client.crt')
, keyFile = path.resolve(__dirname, 'ssl/client.key')
, caFile = path.resolve(__dirname, 'ssl/ca.cert.pem')
, request = require('request');
const options = {
url: 'https://api.some-server.com/',
cert: fs.readFileSync(certFile),
key: fs.readFileSync(keyFile),
passphrase: 'password',
ca: fs.readFileSync(caFile)
};
request.get(options);
```
### Using `options.agentOptions`
In the example below, we call an API that requires client side SSL certificate
(in PEM format) with passphrase protected private key (in PEM format) and disable the SSLv3 protocol:
```js
const fs = require('fs')
, path = require('path')
, certFile = path.resolve(__dirname, 'ssl/client.crt')
, keyFile = path.resolve(__dirname, 'ssl/client.key')
, request = require('request');
const options = {
url: 'https://api.some-server.com/',
agentOptions: {
cert: fs.readFileSync(certFile),
key: fs.readFileSync(keyFile),
// Or use `pfx` property replacing `cert` and `key` when using private key, certificate and CA certs in PFX or PKCS12 format:
// pfx: fs.readFileSync(pfxFilePath),
passphrase: 'password',
securityOptions: 'SSL_OP_NO_SSLv3'
}
};
request.get(options);
```
It is able to force using SSLv3 only by specifying `secureProtocol`:
```js
request.get({
url: 'https://api.some-server.com/',
agentOptions: {
secureProtocol: 'SSLv3_method'
}
});
```
It is possible to accept other certificates than those signed by generally allowed Certificate Authorities (CAs).
This can be useful, for example, when using self-signed certificates.
To require a different root certificate, you can specify the signing CA by adding the contents of the CA's certificate file to the `agentOptions`.
The certificate the domain presents must be signed by the root certificate specified:
```js
request.get({
url: 'https://api.some-server.com/',
agentOptions: {
ca: fs.readFileSync('ca.cert.pem')
}
});
```
The `ca` value can be an array of certificates, in the event you have a private or internal corporate public-key infrastructure hierarchy. For example, if you want to connect to https://api.some-server.com which presents a key chain consisting of:
1. its own public key, which is signed by:
2. an intermediate "Corp Issuing Server", that is in turn signed by:
3. a root CA "Corp Root CA";
you can configure your request as follows:
```js
request.get({
url: 'https://api.some-server.com/',
agentOptions: {
ca: [
fs.readFileSync('Corp Issuing Server.pem'),
fs.readFileSync('Corp Root CA.pem')
]
}
});
```

## Support for HAR 1.2
The `options.har` property will override the values: `url`, `method`, `qs`, `headers`, `form`, `formData`, `body`, `json`, as well as construct multipart data and read files from disk when `request.postData.params[].fileName` is present without a matching `value`.
A validation step will check if the HAR Request format matches the latest spec (v1.2) and will skip parsing if not matching.
```js
const request = require('request')
request({
// will be ignored
method: 'GET',
uri: 'http://www.google.com',
// HTTP Archive Request Object
har: {
url: 'http://www.mockbin.com/har',
method: 'POST',
headers: [
{
name: 'content-type',
value: 'application/x-www-form-urlencoded'
}
],
postData: {
mimeType: 'application/x-www-form-urlencoded',
params: [
{
name: 'foo',
value: 'bar'
},
{
name: 'hello',
value: 'world'
}
]
}
}
})
// a POST request will be sent to http://www.mockbin.com
// with body an application/x-www-form-urlencoded body:
// foo=bar&hello=world
```
[back to top](#table-of-contents)
---
## request(options, callback)
The first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.
- `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`
- `baseUrl` - fully qualified uri string used as the base url. Most useful with `request.defaults`, for example when you want to do many requests to the same domain. If `baseUrl` is `https://example.com/api/`, then requesting `/end/point?test=true` will fetch `https://example.com/api/end/point?test=true`. When `baseUrl` is given, `uri` must also be a string.
- `method` - http method (default: `"GET"`)
- `headers` - http headers (default: `{}`)
---
- `qs` - object containing querystring values to be appended to the `uri`
- `qsParseOptions` - object containing options to pass to the [qs.parse](https://github.com/hapijs/qs#parsing-objects) method. Alternatively pass options to the [querystring.parse](https://nodejs.org/docs/v0.12.0/api/querystring.html#querystring_querystring_parse_str_sep_eq_options) method using this format `{sep:';', eq:':', options:{}}`
- `qsStringifyOptions` - object containing options to pass to the [qs.stringify](https://github.com/hapijs/qs#stringifying) method. Alternatively pass options to the [querystring.stringify](https://nodejs.org/docs/v0.12.0/api/querystring.html#querystring_querystring_stringify_obj_sep_eq_options) method using this format `{sep:';', eq:':', options:{}}`. For example, to change the way arrays are converted to query strings using the `qs` module pass the `arrayFormat` option with one of `indices|brackets|repeat`
- `useQuerystring` - if true, use `querystring` to stringify and parse
querystrings, otherwise use `qs` (default: `false`). Set this option to
`true` if you need arrays to be serialized as `foo=bar&foo=baz` instead of the
default `foo[0]=bar&foo[1]=baz`.
---
- `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer`, `String` or `ReadStream`. If `json` is `true`, then `body` must be a JSON-serializable object.
- `form` - when passed an object or a querystring, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded` header. When passed no options, a `FormData` instance is returned (and is piped to request). See "Forms" section above.
- `formData` - data to pass for a `multipart/form-data` request. See
[Forms](#forms) section above.
- `multipart` - array of objects which contain their own headers and `body`
attributes. Sends a `multipart/related` request. See [Forms](#forms) section
above.
- Alternatively you can pass in an object `{chunked: false, data: []}` where
`chunked` is used to specify whether the request is sent in
[chunked transfer encoding](https://en.wikipedia.org/wiki/Chunked_transfer_encoding)
In non-chunked requests, data items with body streams are not allowed.
- `preambleCRLF` - append a newline/CRLF before the boundary of your `multipart/form-data` request.
- `postambleCRLF` - append a newline/CRLF at the end of the boundary of your `multipart/form-data` request.
- `json` - sets `body` to JSON representation of value and adds `Content-type: application/json` header. Additionally, parses the response body as JSON.
- `jsonReviver` - a [reviver function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) that will be passed to `JSON.parse()` when parsing a JSON response body.
- `jsonReplacer` - a [replacer function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) that will be passed to `JSON.stringify()` when stringifying a JSON request body.
---
- `auth` - a hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional). See documentation above.
- `oauth` - options for OAuth HMAC-SHA1 signing. See documentation above.
- `hawk` - options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).
- `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`, and optionally `session` (note that this only works for services that require session as part of the canonical string). Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services). If you want to use AWS sign version 4 use the parameter `sign_version` with value `4` otherwise the default is version 2. If you are using SigV4, you can also include a `service` property that specifies the service name. **Note:** you need to `npm install aws4` first.
- `httpSignature` - options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.
---
- `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`). This property can also be implemented as function which gets `response` object as a single argument and should return `true` if redirects should continue or `false` otherwise.
- `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)
- `followOriginalHttpMethod` - by default we redirect to HTTP method GET. you can enable this property to redirect to the original HTTP method (default: `false`)
- `maxRedirects` - the maximum number of redirects to follow (default: `10`)
- `removeRefererHeader` - removes the referer header when a redirect happens (default: `false`). **Note:** if true, referer header set in the initial request is preserved during redirect chain.
---
- `encoding` - encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`. Anything else **(including the default value of `undefined`)** will be passed as the [encoding](http://nodejs.org/api/buffer.html#buffer_buffer) parameter to `toString()` (meaning this is effectively `utf8` by default). (**Note:** if you expect binary data, you should set `encoding: null`.)
- `gzip` - if `true`, add an `Accept-Encoding` header to request compressed content encodings from the server (if not already present) and decode supported content encodings in the response. **Note:** Automatic decoding of the response content is performed on the body data returned through `request` (both through the `request` stream and passed to the callback function) but is not performed on the `response` stream (available from the `response` event) which is the unmodified `http.IncomingMessage` object which may contain compressed data. See example below.
- `jar` - if `true`, remember cookies for future use (or define your custom cookie jar; see examples section)
---
- `agent` - `http(s).Agent` instance to use
- `agentClass` - alternatively specify your agent's class name
- `agentOptions` - and pass its options. **Note:** for HTTPS see [tls API doc for TLS/SSL options](http://nodejs.org/api/tls.html#tls_tls_connect_options_callback) and the [documentation above](#using-optionsagentoptions).
- `forever` - set to `true` to use the [forever-agent](https://github.com/request/forever-agent) **Note:** Defaults to `http(s).Agent({keepAlive:true})` in node 0.12+
- `pool` - an object describing which agents to use for the request. If this option is omitted the request will use the global agent (as long as your options allow for it). Otherwise, request will search the pool for your custom agent. If no custom agent is found, a new agent will be created and added to the pool. **Note:** `pool` is used only when the `agent` option is not specified.
- A `maxSockets` property can also be provided on the `pool` object to set the max number of sockets for all agents created (ex: `pool: {maxSockets: Infinity}`).
- Note that if you are sending multiple requests in a loop and creating
multiple new `pool` objects, `maxSockets` will not work as intended. To
work around this, either use [`request.defaults`](#requestdefaultsoptions)
with your pool options or create the pool object with the `maxSockets`
property outside of the loop.
- `timeout` - integer containing number of milliseconds, controls two timeouts.
- **Read timeout**: Time to wait for a server to send response headers (and start the response body) before aborting the request.
- **Connection timeout**: Sets the socket to timeout after `timeout` milliseconds of inactivity. Note that increasing the timeout beyond the OS-wide TCP connection timeout will not have any effect ([the default in Linux can be anywhere from 20-120 seconds][linux-timeout])
[linux-timeout]: http://www.sekuda.com/overriding_the_default_linux_kernel_20_second_tcp_socket_connect_timeout
---
- `localAddress` - local interface to bind for network connections.
- `proxy` - an HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)
- `strictSSL` - if `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
- `tunnel` - controls the behavior of
[HTTP `CONNECT` tunneling](https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_tunneling)
as follows:
- `undefined` (default) - `true` if the destination is `https`, `false` otherwise
- `true` - always tunnel to the destination by making a `CONNECT` request to
the proxy
- `false` - request the destination as a `GET` request.
- `proxyHeaderWhiteList` - a whitelist of headers to send to a
tunneling proxy.
- `proxyHeaderExclusiveList` - a whitelist of headers to send
exclusively to a tunneling proxy and not to destination.
---
- `time` - if `true`, the request-response cycle (including all redirects) is timed at millisecond resolution. When set, the following properties are added to the response object:
- `elapsedTime` Duration of the entire request/response in milliseconds (*deprecated*).
- `responseStartTime` Timestamp when the response began (in Unix Epoch milliseconds) (*deprecated*).
- `timingStart` Timestamp of the start of the request (in Unix Epoch milliseconds).
- `timings` Contains event timestamps in millisecond resolution relative to `timingStart`. If there were redirects, the properties reflect the timings of the final request in the redirect chain:
- `socket` Relative timestamp when the [`http`](https://nodejs.org/api/http.html#http_event_socket) module's `socket` event fires. This happens when the socket is assigned to the request.
- `lookup` Relative timestamp when the [`net`](https://nodejs.org/api/net.html#net_event_lookup) module's `lookup` event fires. This happens when the DNS has been resolved.
- `connect`: Relative timestamp when the [`net`](https://nodejs.org/api/net.html#net_event_connect) module's `connect` event fires. This happens when the server acknowledges the TCP connection.
- `response`: Relative timestamp when the [`http`](https://nodejs.org/api/http.html#http_event_response) module's `response` event fires. This happens when the first bytes are received from the server.
- `end`: Relative timestamp when the last bytes of the response are received.
- `timingPhases` Contains the durations of each request phase. If there were redirects, the properties reflect the timings of the final request in the redirect chain:
- `wait`: Duration of socket initialization (`timings.socket`)
- `dns`: Duration of DNS lookup (`timings.lookup` - `timings.socket`)
- `tcp`: Duration of TCP connection (`timings.connect` - `timings.socket`)
- `firstByte`: Duration of HTTP server response (`timings.response` - `timings.connect`)
- `download`: Duration of HTTP download (`timings.end` - `timings.response`)
- `total`: Duration entire HTTP round-trip (`timings.end`)
- `har` - a [HAR 1.2 Request Object](http://www.softwareishard.com/blog/har-12-spec/#request), will be processed from HAR format into options overwriting matching values *(see the [HAR 1.2 section](#support-for-har-12) for details)*
- `callback` - alternatively pass the request's callback in the options object
The callback argument gets 3 arguments:
1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)
2. An [`http.IncomingMessage`](https://nodejs.org/api/http.html#http_class_http_incomingmessage) object (Response object)
3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)

## Convenience methods
There are also shorthand methods for different HTTP METHODs and some other conveniences.
### request.defaults(options)
This method **returns a wrapper** around the normal request API that defaults
to whatever options you pass to it.
**Note:** `request.defaults()` **does not** modify the global request API;
instead, it **returns a wrapper** that has your default settings applied to it.
**Note:** You can call `.defaults()` on the wrapper that is returned from
`request.defaults` to add/override defaults that were previously defaulted.
For example:
```js
//requests using baseRequest() will set the 'x-token' header
const baseRequest = request.defaults({
headers: {'x-token': 'my-token'}
})
//requests using specialRequest() will include the 'x-token' header set in
//baseRequest and will also include the 'special' header
const specialRequest = baseRequest.defaults({
headers: {special: 'special value'}
})
```
### request.METHOD()
These HTTP method convenience functions act just like `request()` but with a default method already set for you:
- *request.get()*: Defaults to `method: "GET"`.
- *request.post()*: Defaults to `method: "POST"`.
- *request.put()*: Defaults to `method: "PUT"`.
- *request.patch()*: Defaults to `method: "PATCH"`.
- *request.del() / request.delete()*: Defaults to `method: "DELETE"`.
- *request.head()*: Defaults to `method: "HEAD"`.
- *request.options()*: Defaults to `method: "OPTIONS"`.
### request.cookie()
Function that creates a new cookie.
```js
request.cookie('key1=value1')
```
### request.jar()
Function that creates a new cookie jar.
```js
request.jar()
```
### response.caseless.get('header-name')
Function that returns the specified response header field using a [case-insensitive match](https://tools.ietf.org/html/rfc7230#section-3.2)
```js
request('http://www.google.com', function (error, response, body) {
// print the Content-Type header even if the server returned it as 'content-type' (lowercase)
console.log('Content-Type is:', response.caseless.get('Content-Type'));
});
```

---
## Debugging
There are at least three ways to debug the operation of `request`:
1. Launch the node process like `NODE_DEBUG=request node script.js`
(`lib,request,otherlib` works too).
2. Set `require('request').debug = true` at any time (this does the same thing
as #1).
3. Use the [request-debug module](https://github.com/request/request-debug) to
view request and response headers and bodies.
[back to top](#table-of-contents)
---
## Timeouts
Most requests to external servers should have a timeout attached, in case the
server is not responding in a timely manner. Without a timeout, your code may
have a socket open/consume resources for minutes or more.
There are two main types of timeouts: **connection timeouts** and **read
timeouts**. A connect timeout occurs if the timeout is hit while your client is
attempting to establish a connection to a remote machine (corresponding to the
[connect() call][connect] on the socket). A read timeout occurs any time the
server is too slow to send back a part of the response.
These two situations have widely different implications for what went wrong
with the request, so it's useful to be able to distinguish them. You can detect
timeout errors by checking `err.code` for an 'ETIMEDOUT' value. Further, you
can detect whether the timeout was a connection timeout by checking if the
`err.connect` property is set to `true`.
```js
request.get('http://10.255.255.1', {timeout: 1500}, function(err) {
console.log(err.code === 'ETIMEDOUT');
// Set to `true` if the timeout was a connection timeout, `false` or
// `undefined` otherwise.
console.log(err.connect === true);
process.exit(0);
});
```
[connect]: http://linux.die.net/man/2/connect
## Examples:
```js
const request = require('request')
, rand = Math.floor(Math.random()*100000000).toString()
;
request(
{ method: 'PUT'
, uri: 'http://mikeal.iriscouch.com/testjs/' + rand
, multipart:
[ { 'content-type': 'application/json'
, body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
}
, { body: 'I am an attachment' }
]
}
, function (error, response, body) {
if(response.statusCode == 201){
console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)
} else {
console.log('error: '+ response.statusCode)
console.log(body)
}
}
)
```
For backwards-compatibility, response compression is not supported by default.
To accept gzip-compressed responses, set the `gzip` option to `true`. Note
that the body data passed through `request` is automatically decompressed
while the response object is unmodified and will contain compressed data if
the server sent a compressed response.
```js
const request = require('request')
request(
{ method: 'GET'
, uri: 'http://www.google.com'
, gzip: true
}
, function (error, response, body) {
// body is the decompressed response body
console.log('server encoded the data as: ' + (response.headers['content-encoding'] || 'identity'))
console.log('the decoded data is: ' + body)
}
)
.on('data', function(data) {
// decompressed data as it is received
console.log('decoded chunk: ' + data)
})
.on('response', function(response) {
// unmodified http.IncomingMessage object
response.on('data', function(data) {
// compressed data as it is received
console.log('received ' + data.length + ' bytes of compressed data')
})
})
```
Cookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`).
```js
const request = request.defaults({jar: true})
request('http://www.google.com', function () {
request('http://images.google.com')
})
```
To use a custom cookie jar (instead of `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)
```js
const j = request.jar()
const request = request.defaults({jar:j})
request('http://www.google.com', function () {
request('http://images.google.com')
})
```
OR
```js
const j = request.jar();
const cookie = request.cookie('key1=value1');
const url = 'http://www.google.com';
j.setCookie(cookie, url);
request({url: url, jar: j}, function () {
request('http://images.google.com')
})
```
To use a custom cookie store (such as a
[`FileCookieStore`](https://github.com/mitsuru/tough-cookie-filestore)
which supports saving to and restoring from JSON files), pass it as a parameter
to `request.jar()`:
```js
const FileCookieStore = require('tough-cookie-filestore');
// NOTE - currently the 'cookies.json' file must already exist!
const j = request.jar(new FileCookieStore('cookies.json'));
request = request.defaults({ jar : j })
request('http://www.google.com', function() {
request('http://images.google.com')
})
```
The cookie store must be a
[`tough-cookie`](https://github.com/SalesforceEng/tough-cookie)
store and it must support synchronous operations; see the
[`CookieStore` API docs](https://github.com/SalesforceEng/tough-cookie#api)
for details.
To inspect your cookie jar after a request:
```js
const j = request.jar()
request({url: 'http://www.google.com', jar: j}, function () {
const cookie_string = j.getCookieString(url); // "key1=value1; key2=value2; ..."
const cookies = j.getCookies(url);
// [{key: 'key1', value: 'value1', domain: "www.google.com", ...}, ...]
})
```

[RFC6265](https://tools.ietf.org/html/rfc6265) Cookies and CookieJar for Node.js
[](https://nodei.co/npm/tough-cookie/)
[](https://travis-ci.org/salesforce/tough-cookie)
# Synopsis
``` javascript
var tough = require('tough-cookie');
var Cookie = tough.Cookie;
var cookie = Cookie.parse(header);
cookie.value = 'somethingdifferent';
header = cookie.toString();
var cookiejar = new tough.CookieJar();
cookiejar.setCookie(cookie, 'http://currentdomain.example.com/path', cb);
// ...
cookiejar.getCookies('http://example.com/otherpath',function(err,cookies) {
res.headers['cookie'] = cookies.join('; ');
});
```
# Installation
It's _so_ easy!
`npm install tough-cookie`
Why the name? NPM modules `cookie`, `cookies` and `cookiejar` were already taken.
## Version Support
Support for versions of node.js will follow that of the [request](https://www.npmjs.com/package/request) module.
# API
## tough
Functions on the module you get from `require('tough-cookie')`. All can be used as pure functions and don't need to be "bound".
**Note**: prior to 1.0.x, several of these functions took a `strict` parameter. This has since been removed from the API as it was no longer necessary.
### `parseDate(string)`
Parse a cookie date string into a `Date`. Parses according to RFC6265 Section 5.1.1, not `Date.parse()`.
### `formatDate(date)`
Format a Date into a RFC1123 string (the RFC6265-recommended format).
### `canonicalDomain(str)`
Transforms a domain-name into a canonical domain-name. The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265). For the most part, this function is idempotent (can be run again on its output without ill effects).
### `domainMatch(str,domStr[,canonicalize=true])`
Answers "does this real domain match the domain in a cookie?". The `str` is the "current" domain-name and the `domStr` is the "cookie" domain-name. Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a "suffix match".
The `canonicalize` parameter will run the other two parameters through `canonicalDomain` or not.
### `defaultPath(path)`
Given a current request/response path, gives the Path apropriate for storing in a cookie. This is basically the "directory" of a "file" in the path, but is specified by Section 5.1.4 of the RFC.
The `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.). This is the `.pathname` property of node's `uri.parse()` output.
### `pathMatch(reqPath,cookiePath)`
Answers "does the request-path path-match a given cookie-path?" as per RFC6265 Section 5.1.4. Returns a boolean.
This is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.
### `parse(cookieString[, options])`
alias for `Cookie.parse(cookieString[, options])`
### `fromJSON(string)`
alias for `Cookie.fromJSON(string)`
### `getPublicSuffix(hostname)`
Returns the public suffix of this hostname. The public suffix is the shortest domain-name upon which a cookie can be set. Returns `null` if the hostname cannot have cookies set for it.
For example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.
For further information, see http://publicsuffix.org/. This module derives its list from that site. This call is currently a wrapper around [`psl`](https://www.npmjs.com/package/psl)'s [get() method](https://www.npmjs.com/package/psl#pslgetdomain).
### `cookieCompare(a,b)`
For use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). The sort algorithm is, in order of precedence:
* Longest `.path`
* oldest `.creation` (which has a 1ms precision, same as `Date`)
* lowest `.creationIndex` (to get beyond the 1ms precision)
``` javascript
var cookies = [ /* unsorted array of Cookie objects */ ];
cookies = cookies.sort(cookieCompare);
```
**Note**: Since JavaScript's `Date` is limited to a 1ms precision, cookies within the same milisecond are entirely possible. This is especially true when using the `now` option to `.setCookie()`. The `.creationIndex` property is a per-process global counter, assigned during construction with `new Cookie()`. This preserves the spirit of the RFC sorting: older cookies go first. This works great for `MemoryCookieStore`, since `Set-Cookie` headers are parsed in order, but may not be so great for distributed systems. Sophisticated `Store`s may wish to set this to some other _logical clock_ such that if cookies A and B are created in the same millisecond, but cookie A is created before cookie B, then `A.creationIndex < B.creationIndex`. If you want to alter the global counter, which you probably _shouldn't_ do, it's stored in `Cookie.cookiesCreated`.
### `permuteDomain(domain)`
Generates a list of all possible domains that `domainMatch()` the parameter. May be handy for implementing cookie stores.
### `permutePath(path)`
Generates a list of all possible paths that `pathMatch()` the parameter. May be handy for implementing cookie stores.
## Cookie
Exported via `tough.Cookie`.
### `Cookie.parse(cookieString[, options])`
Parses a single Cookie or Set-Cookie HTTP header into a `Cookie` object. Returns `undefined` if the string can't be parsed.
The options parameter is not required and currently has only one property:
* _loose_ - boolean - if `true` enable parsing of key-less cookies like `=abc` and `=`, which are not RFC-compliant.
If options is not an object, it is ignored, which means you can use `Array#map` with it.
Here's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:
``` javascript
if (res.headers['set-cookie'] instanceof Array)
cookies = res.headers['set-cookie'].map(Cookie.parse);
else
cookies = [Cookie.parse(res.headers['set-cookie'])];
```
_Note:_ in version 2.3.3, tough-cookie limited the number of spaces before the `=` to 256 characters. This limitation has since been removed.
See [Issue 92](https://github.com/salesforce/tough-cookie/issues/92)
### Properties
Cookie object properties:
* _key_ - string - the name or key of the cookie (default "")
* _value_ - string - the value of the cookie (default "")
* _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `"Infinity"`). See `setExpires()`
* _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie. May also be set to strings `"Infinity"` and `"-Infinity"` for non-expiry and immediate-expiry, respectively. See `setMaxAge()`
* _domain_ - string - the `Domain=` attribute of the cookie
* _path_ - string - the `Path=` of the cookie
* _secure_ - boolean - the `Secure` cookie flag
* _httpOnly_ - boolean - the `HttpOnly` cookie flag
* _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)
* _creation_ - `Date` - when this cookie was constructed
* _creationIndex_ - number - set at construction, used to provide greater sort precision (please see `cookieCompare(a,b)` for a full explanation)
After a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:
* _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)
* _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.
* _creation_ - `Date` - **modified** from construction to when the cookie was added to the jar
* _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented. Using `cookiejar.getCookies(...)` will update this attribute.
### `Cookie([{properties}])`
Receives an options object that can contain any of the above Cookie properties, uses the default for unspecified properties.
### `.toString()`
encode to a Set-Cookie header value. The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.
### `.cookieString()`
encode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').
### `.setExpires(String)`
sets the expiry based on a date-string passed through `parseDate()`. If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `"Infinity"` (a string) is set.
### `.setMaxAge(number)`
sets the maxAge in seconds. Coerces `-Infinity` to `"-Infinity"` and `Infinity` to `"Infinity"` so it JSON serializes correctly.
### `.expiryTime([now=Date.now()])`
### `.expiryDate([now=Date.now()])`
expiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object. Note that in both cases the `now` parameter should be milliseconds.
Max-Age takes precedence over Expires (as per the RFC). The `.creation` attribute -- or, by default, the `now` parameter -- is used to offset the `.maxAge` attribute.
If Expires (`.expires`) is set, that's returned.
Otherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for "Tue, 19 Jan 2038 03:14:07 GMT" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).
### `.TTL([now=Date.now()])`
compute the TTL relative to `now` (milliseconds). The same precedence rules as for `expiryTime`/`expiryDate` apply.
The "number" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired. Otherwise a time-to-live in milliseconds is returned.
### `.canonicalizedDomain()`
### `.cdomain()`
return the canonicalized `.domain` field. This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.
### `.toJSON()`
For convenience in using `JSON.serialize(cookie)`. Returns a plain-old `Object` that can be JSON-serialized.
Any `Date` properties (i.e., `.expires`, `.creation`, and `.lastAccessed`) are exported in ISO format (`.toISOString()`).
**NOTE**: Custom `Cookie` properties will be discarded. In tough-cookie 1.x, since there was no `.toJSON` method explicitly defined, all enumerable properties were captured. If you want a property to be serialized, add the property name to the `Cookie.serializableProperties` Array.
### `Cookie.fromJSON(strOrObj)`
Does the reverse of `cookie.toJSON()`. If passed a string, will `JSON.parse()` that first.
Any `Date` properties (i.e., `.expires`, `.creation`, and `.lastAccessed`) are parsed via `Date.parse()`, not the tough-cookie `parseDate`, since it's JavaScript/JSON-y timestamps being handled at this layer.
Returns `null` upon JSON parsing error.
### `.clone()`
Does a deep clone of this cookie, exactly implemented as `Cookie.fromJSON(cookie.toJSON())`.
### `.validate()`
Status: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.
validates cookie attributes for semantic correctness. Useful for "lint" checking any Set-Cookie headers you generate. For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:
``` javascript
if (cookie.validate() === true) {
// it's tasty
} else {
// yuck!
}
```
## CookieJar
Exported via `tough.CookieJar`.
### `CookieJar([store],[options])`
Simply use `new CookieJar()`. If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.
The `options` object can be omitted and can have the following properties:
* _rejectPublicSuffixes_ - boolean - default `true` - reject cookies with domains like "com" and "co.uk"
* _looseMode_ - boolean - default `false` - accept malformed cookies like `bar` and `=bar`, which have an implied empty name.
This is not in the standard, but is used sometimes on the web and is accepted by (most) browsers.
Since eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.
### `.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))`
Attempt to set the cookie in the cookie jar. If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through. The cookie will have updated `.creation`, `.lastAccessed` and `.hostOnly` properties.
The `options` object can be omitted and can have the following properties:
* _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.
* _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
* _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
* _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains. `Store` errors aren't ignored by this option.
As per the RFC, the `.hostOnly` property is set if there was no "Domain=" parameter in the cookie string (or `.domain` was null on the Cookie object). The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case. Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).
### `.setCookieSync(cookieOrString, currentUrl, [{options}])`
Synchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
### `.getCookies(currentUrl, [{options},] cb(err,cookies))`
Retrieve the list of cookies that can be sent in a Cookie header for the current url.
If an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed. The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.
The `options` object can be omitted and can have the following properties:
* _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.
* _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
* _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
* _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store. Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).
* _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the underlying store (the default `MemoryCookieStore` supports it).
The `.lastAccessed` property of the returned cookies will have been updated.
### `.getCookiesSync(currentUrl, [{options}])`
Synchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
### `.getCookieString(...)`
Accepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback. Simply maps the `Cookie` array via `.cookieString()`.
### `.getCookieStringSync(...)`
Synchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
### `.getSetCookieStrings(...)`
Returns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`. Simply maps the cookie array via `.toString()`.
### `.getSetCookieStringsSync(...)`
Synchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
### `.serialize(cb(err,serializedObject))`
Serialize the Jar if the underlying store supports `.getAllCookies`.
**NOTE**: Custom `Cookie` properties will be discarded. If you want a property to be serialized, add the property name to the `Cookie.serializableProperties` Array.
See [Serialization Format].
### `.serializeSync()`
Sync version of .serialize
### `.toJSON()`
Alias of .serializeSync() for the convenience of `JSON.stringify(cookiejar)`.
### `CookieJar.deserialize(serialized, [store], cb(err,object))`
A new Jar is created and the serialized Cookies are added to the underlying store. Each `Cookie` is added via `store.putCookie` in the order in which they appear in the serialization.
The `store` argument is optional, but should be an instance of `Store`. By default, a new instance of `MemoryCookieStore` is created.
As a convenience, if `serialized` is a string, it is passed through `JSON.parse` first. If that throws an error, this is passed to the callback.
### `CookieJar.deserializeSync(serialized, [store])`
Sync version of `.deserialize`. _Note_ that the `store` must be synchronous for this to work.
### `CookieJar.fromJSON(string)`
Alias of `.deserializeSync` to provide consistency with `Cookie.fromJSON()`.
### `.clone([store,]cb(err,newJar))`
Produces a deep clone of this jar. Modifications to the original won't affect the clone, and vice versa.
The `store` argument is optional, but should be an instance of `Store`. By default, a new instance of `MemoryCookieStore` is created. Transferring between store types is supported so long as the source implements `.getAllCookies()` and the destination implements `.putCookie()`.
### `.cloneSync([store])`
Synchronous version of `.clone`, returning a new `CookieJar` instance.
The `store` argument is optional, but must be a _synchronous_ `Store` instance if specified. If not passed, a new instance of `MemoryCookieStore` is used.
The _source_ and _destination_ must both be synchronous `Store`s. If one or both stores are asynchronous, use `.clone` instead. Recall that `MemoryCookieStore` supports both synchronous and asynchronous API calls.
### `.removeAllCookies(cb(err))`
Removes all cookies from the jar.
This is a new backwards-compatible feature of `tough-cookie` version 2.5, so not all Stores will implement it efficiently. For Stores that do not implement `removeAllCookies`, the fallback is to call `removeCookie` after `getAllCookies`. If `getAllCookies` fails or isn't implemented in the Store, that error is returned. If one or more of the `removeCookie` calls fail, only the first error is returned.
### `.removeAllCookiesSync()`
Sync version of `.removeAllCookies()`
## Store
Base class for CookieJar stores. Available as `tough.Store`.
## Store API
The storage model for each `CookieJar` instance can be replaced with a custom implementation. The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file. The API uses continuation-passing-style to allow for asynchronous stores.
Stores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`.
Stores are asynchronous by default, but if `store.synchronous` is set to `true`, then the `*Sync` methods on the of the containing `CookieJar` can be used (however, the continuation-passing style
All `domain` parameters will have been normalized before calling.
The Cookie store must have all of the following methods.
### `store.findCookie(domain, path, key, cb(err,cookie))`
Retrieve a cookie with the given domain, path and key (a.k.a. name). The RFC maintains that exactly one of these cookies should exist in a store. If the store is using versioning, this means that the latest/newest such cookie should be returned.
Callback takes an error and the resulting `Cookie` object. If no cookie is found then `null` MUST be passed instead (i.e. not an error).
### `store.findCookies(domain, path, cb(err,cookies))`
Locates cookies matching the given domain and path. This is most often called in the context of `cookiejar.getCookies()` above.
If no cookies are found, the callback MUST be passed an empty array.
The resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method. However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.
As of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`. If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).
### `store.putCookie(cookie, cb(err))`
Adds a new cookie to the store. The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.
The `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.
Pass an error if the cookie cannot be stored.
### `store.updateCookie(oldCookie, newCookie, cb(err))`
Update an existing cookie. The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`. The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.
The `.lastAccessed` property will always be different between the two objects (to the precision possible via JavaScript's clock). Both `.creation` and `.creationIndex` are guaranteed to be the same. Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are selected for automatic deletion (e.g., least-recently-used, which is up to the store to implement).
Stores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie. If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.
The `newCookie` and `oldCookie` objects MUST NOT be modified.
Pass an error if the newCookie cannot be stored.
### `store.removeCookie(domain, path, key, cb(err))`
Remove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).
The implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.
### `store.removeCookies(domain, path, cb(err))`
Removes matching cookies from the store. The `path` parameter is optional, and if missing means all paths in a domain should be removed.
Pass an error ONLY if removing any existing cookies failed.
### `store.removeAllCookies(cb(err))`
_Optional_. Removes all cookies from the store.
Pass an error if one or more cookies can't be removed.
**Note**: New method as of `tough-cookie` version 2.5, so not all Stores will implement this, plus some stores may choose not to implement this.
### `store.getAllCookies(cb(err, cookies))`
_Optional_. Produces an `Array` of all cookies during `jar.serialize()`. The items in the array can be true `Cookie` objects or generic `Object`s with the [Serialization Format] data structure.
Cookies SHOULD be returned in creation order to preserve sorting via `compareCookies()`. For reference, `MemoryCookieStore` will sort by `.creationIndex` since it uses true `Cookie` objects internally. If you don't return the cookies in creation order, they'll still be sorted by creation time, but this only has a precision of 1ms. See `compareCookies` for more detail.
Pass an error if retrieval fails.
**Note**: not all Stores can implement this due to technical limitations, so it is optional.
## MemoryCookieStore
Inherits from `Store`.
A just-in-memory CookieJar synchronous store implementation, used by default. Despite being a synchronous implementation, it's usable with both the synchronous and asynchronous forms of the `CookieJar` API. Supports serialization, `getAllCookies`, and `removeAllCookies`.
## Community Cookie Stores
These are some Store implementations authored and maintained by the community. They aren't official and we don't vouch for them but you may be interested to have a look:
- [`db-cookie-store`](https://github.com/JSBizon/db-cookie-store): SQL including SQLite-based databases
- [`file-cookie-store`](https://github.com/JSBizon/file-cookie-store): Netscape cookie file format on disk
- [`redis-cookie-store`](https://github.com/benkroeger/redis-cookie-store): Redis
- [`tough-cookie-filestore`](https://github.com/mitsuru/tough-cookie-filestore): JSON on disk
- [`tough-cookie-web-storage-store`](https://github.com/exponentjs/tough-cookie-web-storage-store): DOM localStorage and sessionStorage
# Serialization Format
**NOTE**: if you want to have custom `Cookie` properties serialized, add the property name to `Cookie.serializableProperties`.
```js
{
// The version of tough-cookie that serialized this jar.
version: '[email protected]',
// add the store type, to make humans happy:
storeType: 'MemoryCookieStore',
// CookieJar configuration:
rejectPublicSuffixes: true,
// ... future items go here
// Gets filled from jar.store.getAllCookies():
cookies: [
{
key: 'string',
value: 'string',
// ...
/* other Cookie.serializableProperties go here */
}
]
}

# combined-stream
A stream that emits multiple other streams one after another.
**NB** Currently `combined-stream` works with streams version 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`.
- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
## Installation
``` bash
npm install combined-stream
```
## Usage
Here is a simple example that shows how you can use combined-stream to combine
two files into one:
``` javascript
var CombinedStream = require('combined-stream');
var fs = require('fs');
var combinedStream = CombinedStream.create();
combinedStream.append(fs.createReadStream('file1.txt'));
combinedStream.append(fs.createReadStream('file2.txt'));
combinedStream.pipe(fs.createWriteStream('combined.txt'));
```
While the example above works great, it will pause all source streams until
they are needed. If you don't want that to happen, you can set `pauseStreams`
to `false`:
``` javascript
var CombinedStream = require('combined-stream');
var fs = require('fs');
var combinedStream = CombinedStream.create({pauseStreams: false});
combinedStream.append(fs.createReadStream('file1.txt'));
combinedStream.append(fs.createReadStream('file2.txt'));
combinedStream.pipe(fs.createWriteStream('combined.txt'));
```
However, what if you don't have all the source streams yet, or you don't want
to allocate the resources (file descriptors, memory, etc.) for them right away?
Well, in that case you can simply provide a callback that supplies the stream
by calling a `next()` function:
``` javascript
var CombinedStream = require('combined-stream');
var fs = require('fs');
var combinedStream = CombinedStream.create();
combinedStream.append(function(next) {
next(fs.createReadStream('file1.txt'));
});
combinedStream.append(function(next) {
next(fs.createReadStream('file2.txt'));
});
combinedStream.pipe(fs.createWriteStream('combined.txt'));
```
## API
### CombinedStream.create([options])
Returns a new combined stream object. Available options are:
* `maxDataSize`
* `pauseStreams`
The effect of those options is described below.
### combinedStream.pauseStreams = `true`
Whether to apply back pressure to the underlaying streams. If set to `false`,
the underlaying streams will never be paused. If set to `true`, the
underlaying streams will be paused right after being appended, as well as when
`delayedStream.pipe()` wants to throttle.
### combinedStream.maxDataSize = `2 * 1024 * 1024`
The maximum amount of bytes (or characters) to buffer for all source streams.
If this value is exceeded, `combinedStream` emits an `'error'` event.
### combinedStream.dataSize = `0`
The amount of bytes (or characters) currently buffered by `combinedStream`.
### combinedStream.append(stream)
Appends the given `stream` to the combinedStream object. If `pauseStreams` is
set to `true, this stream will also be paused right away.
`streams` can also be a function that takes one parameter called `next`. `next`
is a function that must be invoked in order to provide the `next` stream, see
example above.
Regardless of how the `stream` is appended, combined-stream always attaches an
`'error'` listener to it, so you don't have to do that manually.
Special case: `stream` can also be a String or Buffer.
### combinedStream.write(data)
You should not call this, `combinedStream` takes care of piping the appended
streams into itself for you.
### combinedStream.resume()
Causes `combinedStream` to start drain the streams it manages. The function is
idempotent, and also emits a `'resume'` event each time which usually goes to
the stream that is currently being drained.
### combinedStream.pause();
If `combinedStream.pauseStreams` is set to `false`, this does nothing.
Otherwise a `'pause'` event is emitted, this goes to the stream that is
currently being drained, so you can use it to apply back pressure.
### combinedStream.end();
Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
all streams from the queue.
### combinedStream.destroy();
Same as `combinedStream.end()`, except it emits a `'close'` event instead of
`'end'`.

# fast-deep-equal
The fastest deep equal with ES6 Map, Set and Typed arrays support.
[](https://travis-ci.org/epoberezkin/fast-deep-equal)
[](https://www.npmjs.com/package/fast-deep-equal)
[](https://coveralls.io/github/epoberezkin/fast-deep-equal?branch=master)
## Install
```bash
npm install fast-deep-equal
```
## Features
- ES5 compatible
- works in node.js (8+) and browsers (IE9+)
- checks equality of Date and RegExp objects by value.
ES6 equal (`require('fast-deep-equal/es6')`) also supports:
- Maps
- Sets
- Typed arrays
## Usage
```javascript
var equal = require('fast-deep-equal');
console.log(equal({foo: 'bar'}, {foo: 'bar'})); // true
```
To support ES6 Maps, Sets and Typed arrays equality use:
```javascript
var equal = require('fast-deep-equal/es6');
console.log(equal(Int16Array([1, 2]), Int16Array([1, 2]))); // true
```
To use with React (avoiding the traversal of React elements' _owner
property that contains circular references and is not needed when
comparing the elements - borrowed from [react-fast-compare](https://github.com/FormidableLabs/react-fast-compare)):
```javascript
var equal = require('fast-deep-equal/react');
var equal = require('fast-deep-equal/es6/react');
```
## Performance benchmark

# performance-now [](https://travis-ci.org/braveg1rl/performance-now) [](https://david-dm.org/braveg1rl/performance-now)
Implements a function similar to `performance.now` (based on `process.hrtime`).
Modern browsers have a `window.performance` object with - among others - a `now` method which gives time in milliseconds, but with sub-millisecond precision. This module offers the same function based on the Node.js native `process.hrtime` function.
Using `process.hrtime` means that the reported time will be monotonically increasing, and not subject to clock-drift.
According to the [High Resolution Time specification](http://www.w3.org/TR/hr-time/), the number of milliseconds reported by `performance.now` should be relative to the value of `performance.timing.navigationStart`.
In the current version of the module (2.0) the reported time is relative to the time the current Node process has started (inferred from `process.uptime()`).
Version 1.0 reported a different time. The reported time was relative to the time the module was loaded (i.e. the time it was first `require`d). If you need this functionality, version 1.0 is still available on NPM.
## Example usage
```javascript
var now = require("performance-now")
var start = now()
var end = now()
console.log(start.toFixed(3)) // the number of milliseconds the current node process is running
console.log((start-end).toFixed(3)) // ~ 0.002 on my system
```
Running the now function two times right after each other yields a time difference of a few microseconds. Given this overhead, I think it's best to assume that the precision of intervals computed with this method is not higher than 10 microseconds, if you don't know the exact overhead on your own system.

## Please [sponsor Ajv development](https://github.com/sponsors/epoberezkin)
I will get straight to the point - I need your support to ensure that the development of Ajv continues.
I have developed Ajv for 5 years in my free time, but it is not sustainable. I'd appreciate if you consider supporting its further development with donations:
- [GitHub sponsors page](https://github.com/sponsors/epoberezkin) (GitHub will match it)
- [Ajv Open Collective️](https://opencollective.com/ajv)
There are many small and large improvements that are long due, including the support of the next versions of JSON Schema specification, improving website and documentation, and making Ajv more modular and maintainable to address its limitations - what Ajv needs to evolve is much more than what I can contribute in my free time.
I would also really appreciate any advice you could give on how to raise funds for Ajv development - whether some suitable open-source fund I could apply to or some sponsor I should approach.
Since 2015 Ajv has become widely used, thanks to your help and contributions:
- **90** contributors 🏗
- **5,000** dependent npm packages ⚙️
- **7,000** github stars, from GitHub users [all over the world](https://www.google.com/maps/d/u/0/viewer?mid=1MGRV8ciFUGIbO1l0EKFWNJGYE7iSkDxP&ll=-3.81666561775622e-14%2C4.821737100000007&z=2) ⭐️
- **5,000,000** dependent repositories on GitHub 🚀
- **120,000,000** npm downloads per month! 💯
I believe it would benefit all Ajv users to help put together the fund that will be used for its further development - it would allow to bring some additional maintainers to the project.
Thank you

## Using version 6
[JSON Schema draft-07](http://json-schema.org/latest/json-schema-validation.html) is published.
[Ajv version 6.0.0](https://github.com/ajv-validator/ajv/releases/tag/v6.0.0) that supports draft-07 is released. It may require either migrating your schemas or updating your code (to continue using draft-04 and v5 schemas, draft-06 schemas will be supported without changes).
__Please note__: To use Ajv with draft-06 schemas you need to explicitly add the meta-schema to the validator instance:
```javascript
ajv.addMetaSchema(require('ajv/lib/refs/json-schema-draft-06.json'));
```
To use Ajv with draft-04 schemas in addition to explicitly adding meta-schema you also need to use option schemaId:
```javascript
var ajv = new Ajv({schemaId: 'id'});
// If you want to use both draft-04 and draft-06/07 schemas:
// var ajv = new Ajv({schemaId: 'auto'});
ajv.addMetaSchema(require('ajv/lib/refs/json-schema-draft-04.json'));
```

## Performance
Ajv generates code using [doT templates](https://github.com/olado/doT) to turn JSON Schemas into super-fast validation functions that are efficient for v8 optimization.
Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks:
- [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) - 50% faster than the second place
- [jsck benchmark](https://github.com/pandastrike/jsck#benchmarks) - 20-190% faster
- [z-schema benchmark](https://rawgit.com/zaggino/z-schema/master/benchmark/results.html)
- [themis benchmark](https://cdn.rawgit.com/playlyfe/themis/master/benchmark/results.html)

- [$data reference](#data-reference) to use values from the validated data as values for the schema keywords
- [asynchronous validation](#asynchronous-validation) of custom formats and keywords
Currently Ajv is the only validator that passes all the tests from [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (according to [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark), apart from the test that requires that `1.0` is not an integer that is impossible to satisfy in JavaScript).
## Install
```
npm install ajv
```
## <a name="usage"></a>Getting started
Try it in the Node.js REPL: https://tonicdev.com/npm/ajv
The fastest validation call:
```javascript
// Node.js require:
var Ajv = require('ajv');
// or ESM/TypeScript import
import Ajv from 'ajv';
var ajv = new Ajv(); // options can be passed, e.g. {allErrors: true}
var validate = ajv.compile(schema);
var valid = validate(data);
if (!valid) console.log(validate.errors);
```
or with less code
```javascript
// ...
var valid = ajv.validate(schema, data);
if (!valid) console.log(ajv.errors);
// ...
```
or
```javascript
// ...
var valid = ajv.addSchema(schema, 'mySchema')
.validate('mySchema', data);
if (!valid) console.log(ajv.errorsText());
// ...
```
See [API](#api) and [Options](#options) for more details.
Ajv compiles schemas to functions and caches them in all cases (using schema serialized with [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) or a custom function as a key), so that the next time the same schema is used (not necessarily the same object instance) it won't be compiled again.
The best performance is achieved when using compiled functions returned by `compile` or `getSchema` methods (there is no additional function call).
__Please note__: every time a validation function or `ajv.validate` are called `errors` property is overwritten. You need to copy `errors` array reference to another variable if you want to use it later (e.g., in the callback). See [Validation errors](#validation-errors)
__Note for TypeScript users__: `ajv` provides its own TypeScript declarations
out of the box, so you don't need to install the deprecated `@types/ajv`
module.
## Using in browser
You can require Ajv directly from the code you browserify - in this case Ajv will be a part of your bundle.
If you need to use Ajv in several bundles you can create a separate UMD bundle using `npm run bundle` script (thanks to [siddo420](https://github.com/siddo420)).
Then you need to load Ajv in the browser:
```html
<script src="ajv.min.js"></script>
```
This bundle can be used with different module systems; it creates global `Ajv` if no module system is found.
The browser bundle is available on [cdnjs](https://cdnjs.com/libraries/ajv).
Ajv is tested with these browsers:
[](https://saucelabs.com/u/epoberezkin)
__Please note__: some frameworks, e.g. Dojo, may redefine global require in such way that is not compatible with CommonJS module format. In such case Ajv bundle has to be loaded before the framework and then you can use global Ajv (see issue [#234](https://github.com/ajv-validator/ajv/issues/234)).
### Ajv and Content Security Policies (CSP)
If you're using Ajv to compile a schema (the typical use) in a browser document that is loaded with a Content Security Policy (CSP), that policy will require a `script-src` directive that includes the value `'unsafe-eval'`.
:warning: NOTE, however, that `unsafe-eval` is NOT recommended in a secure CSP[[1]](https://developer.chrome.com/extensions/contentSecurityPolicy#relaxing-eval), as it has the potential to open the document to cross-site scripting (XSS) attacks.
In order to make use of Ajv without easing your CSP, you can [pre-compile a schema using the CLI](https://github.com/ajv-validator/ajv-cli#compile-schemas). This will transpile the schema JSON into a JavaScript file that exports a `validate` function that works simlarly to a schema compiled at runtime.
Note that pre-compilation of schemas is performed using [ajv-pack](https://github.com/ajv-validator/ajv-pack) and there are [some limitations to the schema features it can compile](https://github.com/ajv-validator/ajv-pack#limitations). A successfully pre-compiled schema is equivalent to the same schema compiled at runtime.
## Command line interface
CLI is available as a separate npm package [ajv-cli](https://github.com/ajv-validator/ajv-cli). It supports:
- compiling JSON Schemas to test their validity
- BETA: generating standalone module exporting a validation function to be used without Ajv (using [ajv-pack](https://github.com/ajv-validator/ajv-pack))
- migrate schemas to draft-07 (using [json-schema-migrate](https://github.com/epoberezkin/json-schema-migrate))
- validating data file(s) against JSON Schema
- testing expected validity of data against JSON Schema
- referenced schemas
- custom meta-schemas
- files in JSON, JSON5, YAML, and JavaScript format
- all Ajv options
- reporting changes in data after validation in [JSON-patch](https://tools.ietf.org/html/rfc6902) format
## Validation keywords
Ajv supports all validation keywords from draft-07 of JSON Schema standard:
- [type](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#type)
- [for numbers](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#keywords-for-numbers) - maximum, minimum, exclusiveMaximum, exclusiveMinimum, multipleOf
- [for strings](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#keywords-for-strings) - maxLength, minLength, pattern, format
- [for arrays](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#keywords-for-arrays) - maxItems, minItems, uniqueItems, items, additionalItems, [contains](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#contains)
- [for objects](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#keywords-for-objects) - maxProperties, minProperties, required, properties, patternProperties, additionalProperties, dependencies, [propertyNames](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#propertynames)
- [for all types](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#keywords-for-all-types) - enum, [const](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#const)
- [compound keywords](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#compound-keywords) - not, oneOf, anyOf, allOf, [if/then/else](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#ifthenelse)
With [ajv-keywords](https://github.com/ajv-validator/ajv-keywords) package Ajv also supports validation keywords from [JSON Schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) for JSON Schema standard:
- [patternRequired](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#patternrequired-proposed) - like `required` but with patterns that some property should match.
- [formatMaximum, formatMinimum, formatExclusiveMaximum, formatExclusiveMinimum](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md#formatmaximum--formatminimum-and-exclusiveformatmaximum--exclusiveformatminimum-proposed) - setting limits for date, time, etc.
See [JSON Schema validation keywords](https://github.com/ajv-validator/ajv/blob/master/KEYWORDS.md) for more details.
## Annotation keywords
JSON Schema specification defines several annotation keywords that describe schema itself but do not perform any validation.
- `title` and `description`: information about the data represented by that schema
- `$comment` (NEW in draft-07): information for developers. With option `$comment` Ajv logs or passes the comment string to the user-supplied function. See [Options](#options).
- `default`: a default value of the data instance, see [Assigning defaults](#assigning-defaults).
- `examples` (NEW in draft-06): an array of data instances. Ajv does not check the validity of these instances against the schema.
- `readOnly` and `writeOnly` (NEW in draft-07): marks data-instance as read-only or write-only in relation to the source of the data (database, api, etc.).
- `contentEncoding`: [RFC 2045](https://tools.ietf.org/html/rfc2045#section-6.1 ), e.g., "base64".
- `contentMediaType`: [RFC 2046](https://tools.ietf.org/html/rfc2046), e.g., "image/png".
__Please note__: Ajv does not implement validation of the keywords `examples`, `contentEncoding` and `contentMediaType` but it reserves them. If you want to create a plugin that implements some of them, it should remove these keywords from the instance.
## Formats
Ajv implements formats defined by JSON Schema specification and several other formats. It is recommended NOT to use "format" keyword implementations with untrusted data, as they use potentially unsafe regular expressions - see [ReDoS attack](#redos-attack).
__Please note__: if you need to use "format" keyword to validate untrusted data, you MUST assess their suitability and safety for your validation scenarios.
The following formats are implemented for string validation with "format" keyword:
- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6).
- _time_: time with optional time-zone.
- _date-time_: date-time from the same source (time-zone is mandatory). `date`, `time` and `date-time` validate ranges in `full` mode and only regexp in `fast` mode (see [options](#options)).
- _uri_: full URI.
- _uri-reference_: URI reference, including full and relative URIs.
- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570)
- _url_ (deprecated): [URL record](https://url.spec.whatwg.org/#concept-url).
- _email_: email address.
- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5).
- _ipv4_: IP address v4.
- _ipv6_: IP address v6.
- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor.
- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122).
- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901).
- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00).
__Please note__: JSON Schema draft-07 also defines formats `iri`, `iri-reference`, `idn-hostname` and `idn-email` for URLs, hostnames and emails with international characters. Ajv does not implement these formats. If you create Ajv plugin that implements them please make a PR to mention this plugin here.
There are two modes of format validation: `fast` and `full`. This mode affects formats `date`, `time`, `date-time`, `uri`, `uri-reference`, and `email`. See [Options](#options) for details.
You can add additional formats and replace any of the formats above using [addFormat](#api-addformat) method.
The option `unknownFormats` allows changing the default behaviour when an unknown format is encountered. In this case Ajv can either fail schema compilation (default) or ignore it (default in versions before 5.0.0). You also can whitelist specific format(s) to be ignored. See [Options](#options) for details.
You can find regular expressions used for format validation and the sources that were used in [formats.js](https://github.com/ajv-validator/ajv/blob/master/lib/compile/formats.js).
## <a name="ref"></a>Combining schemas with $ref
You can structure your validation logic across multiple schema files and have schemas reference each other using `$ref` keyword.
Example:
```javascript
var schema = {
"$id": "http://example.com/schemas/schema.json",
"type": "object",
"properties": {
"foo": { "$ref": "defs.json#/definitions/int" },
"bar": { "$ref": "defs.json#/definitions/str" }
}
};
var defsSchema = {
"$id": "http://example.com/schemas/defs.json",
"definitions": {
"int": { "type": "integer" },
"str": { "type": "string" }
}
};
```
Now to compile your schema you can either pass all schemas to Ajv instance:
```javascript
var ajv = new Ajv({schemas: [schema, defsSchema]});
var validate = ajv.getSchema('http://example.com/schemas/schema.json');
```
or use `addSchema` method:
```javascript
var ajv = new Ajv;
var validate = ajv.addSchema(defsSchema)
.compile(schema);
```
See [Options](#options) and [addSchema](#api) method.
__Please note__:
- `$ref` is resolved as the uri-reference using schema $id as the base URI (see the example).
- References can be recursive (and mutually recursive) to implement the schemas for different data structures (such as linked lists, trees, graphs, etc.).
- You don't have to host your schema files at the URIs that you use as schema $id. These URIs are only used to identify the schemas, and according to JSON Schema specification validators should not expect to be able to download the schemas from these URIs.
- The actual location of the schema file in the file system is not used.
- You can pass the identifier of the schema as the second parameter of `addSchema` method or as a property name in `schemas` option. This identifier can be used instead of (or in addition to) schema $id.
- You cannot have the same $id (or the schema identifier) used for more than one schema - the exception will be thrown.
- You can implement dynamic resolution of the referenced schemas using `compileAsync` method. In this way you can store schemas in any system (files, web, database, etc.) and reference them without explicitly adding to Ajv instance. See [Asynchronous schema compilation](#asynchronous-schema-compilation).
## $data reference
With `$data` option you can use values from the validated data as the values for the schema keywords. See [proposal](https://github.com/json-schema-org/json-schema-spec/issues/51) for more information about how it works.
`$data` reference is supported in the keywords: const, enum, format, maximum/minimum, exclusiveMaximum / exclusiveMinimum, maxLength / minLength, maxItems / minItems, maxProperties / minProperties, formatMaximum / formatMinimum, formatExclusiveMaximum / formatExclusiveMinimum, multipleOf, pattern, required, uniqueItems.
The value of "$data" should be a [JSON-pointer](https://tools.ietf.org/html/rfc6901) to the data (the root is always the top level data object, even if the $data reference is inside a referenced subschema) or a [relative JSON-pointer](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00) (it is relative to the current point in data; if the $data reference is inside a referenced subschema it cannot point to the data outside of the root level for this subschema).
Examples.
This schema requires that the value in property `smaller` is less or equal than the value in the property larger:
```javascript
var ajv = new Ajv({$data: true});
var schema = {
"properties": {
"smaller": {
"type": "number",
"maximum": { "$data": "1/larger" }
},
"larger": { "type": "number" }
}
};
var validData = {
smaller: 5,
larger: 7
};
ajv.validate(schema, validData); // true
```
This schema requires that the properties have the same format as their field names:
```javascript
var schema = {
"additionalProperties": {
"type": "string",
"format": { "$data": "0#" }
}
};
var validData = {
'date-time': '1963-06-19T08:30:06.283185Z',
email: '[email protected]'
}
```
`$data` reference is resolved safely - it won't throw even if some property is undefined. If `$data` resolves to `undefined` the validation succeeds (with the exclusion of `const` keyword). If `$data` resolves to incorrect type (e.g. not "number" for maximum keyword) the validation fails.
## $merge and $patch keywords
With the package [ajv-merge-patch](https://github.com/ajv-validator/ajv-merge-patch) you can use the keywords `$merge` and `$patch` that allow extending JSON Schemas with patches using formats [JSON Merge Patch (RFC 7396)](https://tools.ietf.org/html/rfc7396) and [JSON Patch (RFC 6902)](https://tools.ietf.org/html/rfc6902).
To add keywords `$merge` and `$patch` to Ajv instance use this code:
```javascript
require('ajv-merge-patch')(ajv);
```
Examples.
Using `$merge`:
```json
{
"$merge": {
"source": {
"type": "object",
"properties": { "p": { "type": "string" } },
"additionalProperties": false
},
"with": {
"properties": { "q": { "type": "number" } }
}
}
}
```
Using `$patch`:
```json
{
"$patch": {
"source": {
"type": "object",
"properties": { "p": { "type": "string" } },
"additionalProperties": false
},
"with": [
{ "op": "add", "path": "/properties/q", "value": { "type": "number" } }
]
}
}
```
The schemas above are equivalent to this schema:
```json
{
"type": "object",
"properties": {
"p": { "type": "string" },
"q": { "type": "number" }
},
"additionalProperties": false
}
```
The properties `source` and `with` in the keywords `$merge` and `$patch` can use absolute or relative `$ref` to point to other schemas previously added to the Ajv instance or to the fragments of the current schema.
See the package [ajv-merge-patch](https://github.com/ajv-validator/ajv-merge-patch) for more information.
## Defining custom keywords
The advantages of using custom keywords are:
- allow creating validation scenarios that cannot be expressed using JSON Schema
- simplify your schemas
- help bringing a bigger part of the validation logic to your schemas
- make your schemas more expressive, less verbose and closer to your application domain
- implement custom data processors that modify your data (`modifying` option MUST be used in keyword definition) and/or create side effects while the data is being validated
If a keyword is used only for side-effects and its validation result is pre-defined, use option `valid: true/false` in keyword definition to simplify both generated code (no error handling in case of `valid: true`) and your keyword functions (no need to return any validation result).
The concerns you have to be aware of when extending JSON Schema standard with custom keywords are the portability and understanding of your schemas. You will have to support these custom keywords on other platforms and to properly document these keywords so that everybody can understand them in your schemas.
You can define custom keywords with [addKeyword](#api-addkeyword) method. Keywords are defined on the `ajv` instance level - new instances will not have previously defined keywords.
Ajv allows defining keywords with:
- validation function
- compilation function
- macro function
- inline compilation function that should return code (as string) that will be inlined in the currently compiled schema.
Example. `range` and `exclusiveRange` keywords using compiled schema:
```javascript
ajv.addKeyword('range', {
type: 'number',
compile: function (sch, parentSchema) {
var min = sch[0];
var max = sch[1];
return parentSchema.exclusiveRange === true
? function (data) { return data > min && data < max; }
: function (data) { return data >= min && data <= max; }
}
});
var schema = { "range": [2, 4], "exclusiveRange": true };
var validate = ajv.compile(schema);
console.log(validate(2.01)); // true
console.log(validate(3.99)); // true
console.log(validate(2)); // false
console.log(validate(4)); // false
```
Several custom keywords (typeof, instanceof, range and propertyNames) are defined in [ajv-keywords](https://github.com/ajv-validator/ajv-keywords) package - they can be used for your schemas and as a starting point for your own custom keywords.
See [Defining custom keywords](https://github.com/ajv-validator/ajv/blob/master/CUSTOM.md) for more details.
## Asynchronous schema compilation
During asynchronous compilation remote references are loaded using supplied function. See `compileAsync` [method](#api-compileAsync) and `loadSchema` [option](#options).
Example:
```javascript
var ajv = new Ajv({ loadSchema: loadSchema });
ajv.compileAsync(schema).then(function (validate) {
var valid = validate(data);
// ...
});
function loadSchema(uri) {
return request.json(uri).then(function (res) {
if (res.statusCode >= 400)
throw new Error('Loading error: ' + res.statusCode);
return res.body;
});
}
```
__Please note__: [Option](#options) `missingRefs` should NOT be set to `"ignore"` or `"fail"` for asynchronous compilation to work.
## Asynchronous validation
Example in Node.js REPL: https://tonicdev.com/esp/ajv-asynchronous-validation
You can define custom formats and keywords that perform validation asynchronously by accessing database or some other service. You should add `async: true` in the keyword or format definition (see [addFormat](#api-addformat), [addKeyword](#api-addkeyword) and [Defining custom keywords](#defining-custom-keywords)).
If your schema uses asynchronous formats/keywords or refers to some schema that contains them it should have `"$async": true` keyword so that Ajv can compile it correctly. If asynchronous format/keyword or reference to asynchronous schema is used in the schema without `$async` keyword Ajv will throw an exception during schema compilation.
__Please note__: all asynchronous subschemas that are referenced from the current or other schemas should have `"$async": true` keyword as well, otherwise the schema compilation will fail.
Validation function for an asynchronous custom format/keyword should return a promise that resolves with `true` or `false` (or rejects with `new Ajv.ValidationError(errors)` if you want to return custom errors from the keyword function).
Ajv compiles asynchronous schemas to [es7 async functions](http://tc39.github.io/ecmascript-asyncawait/) that can optionally be transpiled with [nodent](https://github.com/MatAtBread/nodent). Async functions are supported in Node.js 7+ and all modern browsers. You can also supply any other transpiler as a function via `processCode` option. See [Options](#options).
The compiled validation function has `$async: true` property (if the schema is asynchronous), so you can differentiate these functions if you are using both synchronous and asynchronous schemas.
Validation result will be a promise that resolves with validated data or rejects with an exception `Ajv.ValidationError` that contains the array of validation errors in `errors` property.
Example:
```javascript
var ajv = new Ajv;
// require('ajv-async')(ajv);
ajv.addKeyword('idExists', {
async: true,
type: 'number',
validate: checkIdExists
});
function checkIdExists(schema, data) {
return knex(schema.table)
.select('id')
.where('id', data)
.then(function (rows) {
return !!rows.length; // true if record is found
});
}

### Using transpilers with asynchronous validation functions.
[ajv-async](https://github.com/ajv-validator/ajv-async) uses [nodent](https://github.com/MatAtBread/nodent) to transpile async functions. To use another transpiler you should separately install it (or load its bundle in the browser).
#### Using nodent
```javascript
var ajv = new Ajv;
require('ajv-async')(ajv);
// in the browser if you want to load ajv-async bundle separately you can:
// window.ajvAsync(ajv);
var validate = ajv.compile(schema); // transpiled es7 async function
validate(data).then(successFunc).catch(errorFunc);
```
#### Using other transpilers
```javascript
var ajv = new Ajv({ processCode: transpileFunc });
var validate = ajv.compile(schema); // transpiled es7 async function
validate(data).then(successFunc).catch(errorFunc);
```
See [Options](#options).
## Security considerations
JSON Schema, if properly used, can replace data sanitisation. It doesn't replace other API security considerations. It also introduces additional security aspects to consider.
##### Security contact
To report a security vulnerability, please use the
[Tidelift security contact](https://tidelift.com/security).
Tidelift will coordinate the fix and disclosure. Please do NOT report security vulnerabilities via GitHub issues.
##### Untrusted schemas
Ajv treats JSON schemas as trusted as your application code. This security model is based on the most common use case, when the schemas are static and bundled together with the application.
If your schemas are received from untrusted sources (or generated from untrusted data) there are several scenarios you need to prevent:
- compiling schemas can cause stack overflow (if they are too deep)
- compiling schemas can be slow (e.g. [#557](https://github.com/ajv-validator/ajv/issues/557))
- validating certain data can be slow
It is difficult to predict all the scenarios, but at the very least it may help to limit the size of untrusted schemas (e.g. limit JSON string length) and also the maximum schema object depth (that can be high for relatively small JSON strings). You also may want to mitigate slow regular expressions in `pattern` and `patternProperties` keywords.
Regardless the measures you take, using untrusted schemas increases security risks.
##### Circular references in JavaScript objects
Ajv does not support schemas and validated data that have circular references in objects. See [issue #802](https://github.com/ajv-validator/ajv/issues/802).
An attempt to compile such schemas or validate such data would cause stack overflow (or will not complete in case of asynchronous validation). Depending on the parser you use, untrusted data can lead to circular references.
##### Security risks of trusted schemas
Some keywords in JSON Schemas can lead to very slow validation for certain data. These keywords include (but may be not limited to):
- `pattern` and `format` for large strings - in some cases using `maxLength` can help mitigate it, but certain regular expressions can lead to exponential validation time even with relatively short strings (see [ReDoS attack](#redos-attack)).
- `patternProperties` for large property names - use `propertyNames` to mitigate, but some regular expressions can have exponential evaluation time as well.
- `uniqueItems` for large non-scalar arrays - use `maxItems` to mitigate
__Please note__: The suggestions above to prevent slow validation would only work if you do NOT use `allErrors: true` in production code (using it would continue validation after validation errors).
You can validate your JSON schemas against [this meta-schema](https://github.com/ajv-validator/ajv/blob/master/lib/refs/json-schema-secure.json) to check that these recommendations are followed:
```javascript
const isSchemaSecure = ajv.compile(require('ajv/lib/refs/json-schema-secure.json'));
const schema1 = {format: 'email'};
isSchemaSecure(schema1); // false
const schema2 = {format: 'email', maxLength: MAX_LENGTH};
isSchemaSecure(schema2); // true
```
__Please note__: following all these recommendation is not a guarantee that validation of untrusted data is safe - it can still lead to some undesirable results.
##### Content Security Policies (CSP)
See [Ajv and Content Security Policies (CSP)](#ajv-and-content-security-policies-csp)
## ReDoS attack
Certain regular expressions can lead to the exponential evaluation time even with relatively short strings.
Please assess the regular expressions you use in the schemas on their vulnerability to this attack - see [safe-regex](https://github.com/substack/safe-regex), for example.
__Please note__: some formats that Ajv implements use [regular expressions](https://github.com/ajv-validator/ajv/blob/master/lib/compile/formats.js) that can be vulnerable to ReDoS attack, so if you use Ajv to validate data from untrusted sources __it is strongly recommended__ to consider the following:
- making assessment of "format" implementations in Ajv.
- using `format: 'fast'` option that simplifies some of the regular expressions (although it does not guarantee that they are safe).
- replacing format implementations provided by Ajv with your own implementations of "format" keyword that either uses different regular expressions or another approach to format validation. Please see [addFormat](#api-addformat) method.
- disabling format validation by ignoring "format" keyword with option `format: false`
Whatever mitigation you choose, please assume all formats provided by Ajv as potentially unsafe and make your own assessment of their suitability for your validation scenarios.
## Filtering data
With [option `removeAdditional`](#options) (added by [andyscott](https://github.com/andyscott)) you can filter data during the validation.
This option modifies original data.
Example:
```javascript
var ajv = new Ajv({ removeAdditional: true });
var schema = {
"additionalProperties": false,
"properties": {
"foo": { "type": "number" },
"bar": {
"additionalProperties": { "type": "number" },
"properties": {
"baz": { "type": "string" }
}
}
}
}
var data = {
"foo": 0,
"additional1": 1, // will be removed; `additionalProperties` == false
"bar": {
"baz": "abc",
"additional2": 2 // will NOT be removed; `additionalProperties` != false
},
}
var validate = ajv.compile(schema);
console.log(validate(data)); // true
console.log(data); // { "foo": 0, "bar": { "baz": "abc", "additional2": 2 }
```
If `removeAdditional` option in the example above were `"all"` then both `additional1` and `additional2` properties would have been removed.
If the option were `"failing"` then property `additional1` would have been removed regardless of its value and property `additional2` would have been removed only if its value were failing the schema in the inner `additionalProperties` (so in the example above it would have stayed because it passes the schema, but any non-number would have been removed).
__Please note__: If you use `removeAdditional` option with `additionalProperties` keyword inside `anyOf`/`oneOf` keywords your validation can fail with this schema, for example:
```json
{
"type": "object",
"oneOf": [
{
"properties": {
"foo": { "type": "string" }
},
"required": [ "foo" ],
"additionalProperties": false
},
{
"properties": {
"bar": { "type": "integer" }
},
"required": [ "bar" ],
"additionalProperties": false
}
]
}
```
The intention of the schema above is to allow objects with either the string property "foo" or the integer property "bar", but not with both and not with any other properties.
With the option `removeAdditional: true` the validation will pass for the object `{ "foo": "abc"}` but will fail for the object `{"bar": 1}`. It happens because while the first subschema in `oneOf` is validated, the property `bar` is removed because it is an additional property according to the standard (because it is not included in `properties` keyword in the same schema).
While this behaviour is unexpected (issues [#129](https://github.com/ajv-validator/ajv/issues/129), [#134](https://github.com/ajv-validator/ajv/issues/134)), it is correct. To have the expected behaviour (both objects are allowed and additional properties are removed) the schema has to be refactored in this way:
```json
{
"type": "object",
"properties": {
"foo": { "type": "string" },
"bar": { "type": "integer" }
},
"additionalProperties": false,
"oneOf": [
{ "required": [ "foo" ] },
{ "required": [ "bar" ] }
]
}
```
The schema above is also more efficient - it will compile into a faster function.
## Assigning defaults
With [option `useDefaults`](#options) Ajv will assign values from `default` keyword in the schemas of `properties` and `items` (when it is the array of schemas) to the missing properties and items.
With the option value `"empty"` properties and items equal to `null` or `""` (empty string) will be considered missing and assigned defaults.
This option modifies original data.
__Please note__: the default value is inserted in the generated validation code as a literal, so the value inserted in the data will be the deep clone of the default in the schema.
Example 1 (`default` in `properties`):
```javascript
var ajv = new Ajv({ useDefaults: true });
var schema = {
"type": "object",
"properties": {
"foo": { "type": "number" },
"bar": { "type": "string", "default": "baz" }
},
"required": [ "foo", "bar" ]
};
var data = { "foo": 1 };
var validate = ajv.compile(schema);
console.log(validate(data)); // true
console.log(data); // { "foo": 1, "bar": "baz" }
```
Example 2 (`default` in `items`):
```javascript
var schema = {
"type": "array",
"items": [
{ "type": "number" },
{ "type": "string", "default": "foo" }
]
}
var data = [ 1 ];
var validate = ajv.compile(schema);
console.log(validate(data)); // true
console.log(data); // [ 1, "foo" ]
```
`default` keywords in other cases are ignored:
- not in `properties` or `items` subschemas
- in schemas inside `anyOf`, `oneOf` and `not` (see [#42](https://github.com/ajv-validator/ajv/issues/42))
- in `if` subschema of `switch` keyword
- in schemas generated by custom macro keywords
The [`strictDefaults` option](#options) customizes Ajv's behavior for the defaults that Ajv ignores (`true` raises an error, and `"log"` outputs a warning).
## Coercing data types
When you are validating user inputs all your data properties are usually strings. The option `coerceTypes` allows you to have your data types coerced to the types specified in your schema `type` keywords, both to pass the validation and to use the correctly typed data afterwards.
This option modifies original data.
__Please note__: if you pass a scalar value to the validating function its type will be coerced and it will pass the validation, but the value of the variable you pass won't be updated because scalars are passed by value.
Example 1:
```javascript
var ajv = new Ajv({ coerceTypes: true });
var schema = {
"type": "object",
"properties": {
"foo": { "type": "number" },
"bar": { "type": "boolean" }
},
"required": [ "foo", "bar" ]
};
var data = { "foo": "1", "bar": "false" };
var validate = ajv.compile(schema);
console.log(validate(data)); // true
console.log(data); // { "foo": 1, "bar": false }
```
Example 2 (array coercions):
```javascript
var ajv = new Ajv({ coerceTypes: 'array' });
var schema = {
"properties": {
"foo": { "type": "array", "items": { "type": "number" } },
"bar": { "type": "boolean" }
}
};
var data = { "foo": "1", "bar": ["false"] };
var validate = ajv.compile(schema);
console.log(validate(data)); // true
console.log(data); // { "foo": [1], "bar": false }
```
The coercion rules, as you can see from the example, are different from JavaScript both to validate user input as expected and to have the coercion reversible (to correctly validate cases where different types are defined in subschemas of "anyOf" and other compound keywords).
See [Coercion rules](https://github.com/ajv-validator/ajv/blob/master/COERCION.md) for details.
## API
##### new Ajv(Object options) -> Object
Create Ajv instance.
##### .compile(Object schema) -> Function<Object data>
Generate validating function and cache the compiled schema for future use.
Validating function returns a boolean value. This function has properties `errors` and `schema`. Errors encountered during the last validation are assigned to `errors` property (it is assigned `null` if there was no errors). `schema` property contains the reference to the original schema.
The schema passed to this method will be validated against meta-schema unless `validateSchema` option is false. If schema is invalid, an error will be thrown. See [options](#options).
##### <a name="api-compileAsync"></a>.compileAsync(Object schema [, Boolean meta] [, Function callback]) -> Promise
Asynchronous version of `compile` method that loads missing remote schemas using asynchronous function in `options.loadSchema`. This function returns a Promise that resolves to a validation function. An optional callback passed to `compileAsync` will be called with 2 parameters: error (or null) and validating function. The returned promise will reject (and the callback will be called with an error) when:
- missing schema can't be loaded (`loadSchema` returns a Promise that rejects).
- a schema containing a missing reference is loaded, but the reference cannot be resolved.
- schema (or some loaded/referenced schema) is invalid.
The function compiles schema and loads the first missing schema (or meta-schema) until all missing schemas are loaded.
You can asynchronously compile meta-schema by passing `true` as the second parameter.
See example in [Asynchronous compilation](#asynchronous-schema-compilation).
##### .validate(Object schema|String key|String ref, data) -> Boolean
Validate data using passed schema (it will be compiled and cached).
Instead of the schema you can use the key that was previously passed to `addSchema`, the schema id if it was present in the schema or any previously resolved reference.
Validation errors will be available in the `errors` property of Ajv instance (`null` if there were no errors).
__Please note__: every time this method is called the errors are overwritten so you need to copy them to another variable if you want to use them later.
If the schema is asynchronous (has `$async` keyword on the top level) this method returns a Promise. See [Asynchronous validation](#asynchronous-validation).
##### .addSchema(Array<Object>|Object schema [, String key]) -> Ajv
Add schema(s) to validator instance. This method does not compile schemas (but it still validates them). Because of that dependencies can be added in any order and circular dependencies are supported. It also prevents unnecessary compilation of schemas that are containers for other schemas but not used as a whole.
Array of schemas can be passed (schemas should have ids), the second parameter will be ignored.
Key can be passed that can be used to reference the schema and will be used as the schema id if there is no id inside the schema. If the key is not passed, the schema id will be used as the key.
Once the schema is added, it (and all the references inside it) can be referenced in other schemas and used to validate data.
Although `addSchema` does not compile schemas, explicit compilation is not required - the schema will be compiled when it is used first time.
By default the schema is validated against meta-schema before it is added, and if the schema does not pass validation the exception is thrown. This behaviour is controlled by `validateSchema` option.
__Please note__: Ajv uses the [method chaining syntax](https://en.wikipedia.org/wiki/Method_chaining) for all methods with the prefix `add*` and `remove*`.
This allows you to do nice things like the following.
```javascript
var validate = new Ajv().addSchema(schema).addFormat(name, regex).getSchema(uri);
```
##### .addMetaSchema(Array<Object>|Object schema [, String key]) -> Ajv
Adds meta schema(s) that can be used to validate other schemas. That function should be used instead of `addSchema` because there may be instance options that would compile a meta schema incorrectly (at the moment it is `removeAdditional` option).
There is no need to explicitly add draft-07 meta schema (http://json-schema.org/draft-07/schema) - it is added by default, unless option `meta` is set to `false`. You only need to use it if you have a changed meta-schema that you want to use to validate your schemas. See `validateSchema`.
##### <a name="api-validateschema"></a>.validateSchema(Object schema) -> Boolean
Validates schema. This method should be used to validate schemas rather than `validate` due to the inconsistency of `uri` format in JSON Schema standard.
By default this method is called automatically when the schema is added, so you rarely need to use it directly.
If schema doesn't have `$schema` property, it is validated against draft 6 meta-schema (option `meta` should not be false).
If schema has `$schema` property, then the schema with this id (that should be previously added) is used to validate passed schema.
Errors will be available at `ajv.errors`.
##### .getSchema(String key) -> Function<Object data>
Retrieve compiled schema previously added with `addSchema` by the key passed to `addSchema` or by its full reference (id). The returned validating function has `schema` property with the reference to the original schema.
##### .removeSchema([Object schema|String key|String ref|RegExp pattern]) -> Ajv
Remove added/cached schema. Even if schema is referenced by other schemas it can be safely removed as dependent schemas have local references.
Schema can be removed using:
- key passed to `addSchema`
- it's full reference (id)
- RegExp that should match schema id or key (meta-schemas won't be removed)
- actual schema object that will be stable-stringified to remove schema from cache
If no parameter is passed all schemas but meta-schemas will be removed and the cache will be cleared.
##### <a name="api-addformat"></a>.addFormat(String name, String|RegExp|Function|Object format) -> Ajv
Add custom format to validate strings or numbers. It can also be used to replace pre-defined formats for Ajv instance.
Strings are converted to RegExp.
Function should return validation result as `true` or `false`.
If object is passed it should have properties `validate`, `compare` and `async`:
- _validate_: a string, RegExp or a function as described above.
- _compare_: an optional comparison function that accepts two strings and compares them according to the format meaning. This function is used with keywords `formatMaximum`/`formatMinimum` (defined in [ajv-keywords](https://github.com/ajv-validator/ajv-keywords) package). It should return `1` if the first value is bigger than the second value, `-1` if it is smaller and `0` if it is equal.
- _async_: an optional `true` value if `validate` is an asynchronous function; in this case it should return a promise that resolves with a value `true` or `false`.
- _type_: an optional type of data that the format applies to. It can be `"string"` (default) or `"number"` (see https://github.com/ajv-validator/ajv/issues/291#issuecomment-259923858). If the type of data is different, the validation will pass.
Custom formats can be also added via `formats` option.
##### <a name="api-addkeyword"></a>.addKeyword(String keyword, Object definition) -> Ajv
Add custom validation keyword to Ajv instance.
Keyword should be different from all standard JSON Schema keywords and different from previously defined keywords. There is no way to redefine keywords or to remove keyword definition from the instance.
Keyword must start with a letter, `_` or `$`, and may continue with letters, numbers, `_`, `$`, or `-`.
It is recommended to use an application-specific prefix for keywords to avoid current and future name collisions.
Example Keywords:
- `"xyz-example"`: valid, and uses prefix for the xyz project to avoid name collisions.
- `"example"`: valid, but not recommended as it could collide with future versions of JSON Schema etc.
- `"3-example"`: invalid as numbers are not allowed to be the first character in a keyword
Keyword definition is an object with the following properties:
- _type_: optional string or array of strings with data type(s) that the keyword applies to. If not present, the keyword will apply to all types.
- _validate_: validating function
- _compile_: compiling function
- _macro_: macro function
- _inline_: compiling function that returns code (as string)
- _schema_: an optional `false` value used with "validate" keyword to not pass schema
- _metaSchema_: an optional meta-schema for keyword schema
- _dependencies_: an optional list of properties that must be present in the parent schema - it will be checked during schema compilation
- _modifying_: `true` MUST be passed if keyword modifies data
- _statements_: `true` can be passed in case inline keyword generates statements (as opposed to expression)
- _valid_: pass `true`/`false` to pre-define validation result, the result returned from validation function will be ignored. This option cannot be used with macro keywords.
- _$data_: an optional `true` value to support [$data reference](#data-reference) as the value of custom keyword. The reference will be resolved at validation time. If the keyword has meta-schema it would be extended to allow $data and it will be used to validate the resolved value. Supporting $data reference requires that keyword has validating function (as the only option or in addition to compile, macro or inline function).
- _async_: an optional `true` value if the validation function is asynchronous (whether it is compiled or passed in _validate_ property); in this case it should return a promise that resolves with a value `true` or `false`. This option is ignored in case of "macro" and "inline" keywords.
- _errors_: an optional boolean or string `"full"` indicating whether keyword returns errors. If this property is not set Ajv will determine if the errors were set in case of failed validation.
_compile_, _macro_ and _inline_ are mutually exclusive, only one should be used at a time. _validate_ can be used separately or in addition to them to support $data reference.
__Please note__: If the keyword is validating data type that is different from the type(s) in its definition, the validation function will not be called (and expanded macro will not be used), so there is no need to check for data type inside validation function or inside schema returned by macro function (unless you want to enforce a specific type and for some reason do not want to use a separate `type` keyword for that). In the same way as standard keywords work, if the keyword does not apply to the data type being validated, the validation of this keyword will succeed.
See [Defining custom keywords](#defining-custom-keywords) for more details.
##### .getKeyword(String keyword) -> Object|Boolean
Returns custom keyword definition, `true` for pre-defined keywords and `false` if the keyword is unknown.
##### .removeKeyword(String keyword) -> Ajv
Removes custom or pre-defined keyword so you can redefine them.
While this method can be used to extend pre-defined keywords, it can also be used to completely change their meaning - it may lead to unexpected results.
__Please note__: schemas compiled before the keyword is removed will continue to work without changes. To recompile schemas use `removeSchema` method and compile them again.
##### .errorsText([Array<Object> errors [, Object options]]) -> String
Returns the text with all errors in a String.
Options can have properties `separator` (string used to separate errors, ", " by default) and `dataVar` (the variable name that dataPaths are prefixed with, "data" by default).

##### Validation and reporting options
- _$data_: support [$data references](#data-reference). Draft 6 meta-schema that is added by default will be extended to allow them. If you want to use another meta-schema you need to use $dataMetaSchema method to add support for $data reference. See [API](#api).
- _allErrors_: check all rules collecting all errors. Default is to return after the first error.
- _verbose_: include the reference to the part of the schema (`schema` and `parentSchema`) and validated data in errors (false by default).
- _$comment_ (NEW in Ajv version 6.0): log or pass the value of `$comment` keyword to a function. Option values:
- `false` (default): ignore $comment keyword.
- `true`: log the keyword value to console.
- function: pass the keyword value, its schema path and root schema to the specified function
- _jsonPointers_: set `dataPath` property of errors using [JSON Pointers](https://tools.ietf.org/html/rfc6901) instead of JavaScript property access notation.
- _uniqueItems_: validate `uniqueItems` keyword (true by default).
- _unicode_: calculate correct length of strings with unicode pairs (true by default). Pass `false` to use `.length` of strings that is faster, but gives "incorrect" lengths of strings with unicode pairs - each unicode pair is counted as two characters.
- _nullable_: support keyword "nullable" from [Open API 3 specification](https://swagger.io/docs/specification/data-models/data-types/).
- _format_: formats validation mode. Option values:
- `"fast"` (default) - simplified and fast validation (see [Formats](#formats) for details of which formats are available and affected by this option).
- `"full"` - more restrictive and slow validation. E.g., 25:00:00 and 2015/14/33 will be invalid time and date in 'full' mode but it will be valid in 'fast' mode.
- `false` - ignore all format keywords.
- _formats_: an object with custom formats. Keys and values will be passed to `addFormat` method.
- _keywords_: an object with custom keywords. Keys and values will be passed to `addKeyword` method.
- _unknownFormats_: handling of unknown formats. Option values:
- `true` (default) - if an unknown format is encountered the exception is thrown during schema compilation. If `format` keyword value is [$data reference](#data-reference) and it is unknown the validation will fail.
- `[String]` - an array of unknown format names that will be ignored. This option can be used to allow usage of third party schemas with format(s) for which you don't have definitions, but still fail if another unknown format is used. If `format` keyword value is [$data reference](#data-reference) and it is not in this array the validation will fail.
- `"ignore"` - to log warning during schema compilation and always pass validation (the default behaviour in versions before 5.0.0). This option is not recommended, as it allows to mistype format name and it won't be validated without any error message. This behaviour is required by JSON Schema specification.
- _schemas_: an array or object of schemas that will be added to the instance. In case you pass the array the schemas must have IDs in them. When the object is passed the method `addSchema(value, key)` will be called for each schema in this object.
- _logger_: sets the logging method. Default is the global `console` object that should have methods `log`, `warn` and `error`. See [Error logging](#error-logging). Option values:
- custom logger - it should have methods `log`, `warn` and `error`. If any of these methods is missing an exception will be thrown.
- `false` - logging is disabled.
##### Referenced schema options
- _schemaId_: this option defines which keywords are used as schema URI. Option value:
- `"$id"` (default) - only use `$id` keyword as schema URI (as specified in JSON Schema draft-06/07), ignore `id` keyword (if it is present a warning will be logged).
- `"id"` - only use `id` keyword as schema URI (as specified in JSON Schema draft-04), ignore `$id` keyword (if it is present a warning will be logged).
- `"auto"` - use both `$id` and `id` keywords as schema URI. If both are present (in the same schema object) and different the exception will be thrown during schema compilation.
- _missingRefs_: handling of missing referenced schemas. Option values:
- `true` (default) - if the reference cannot be resolved during compilation the exception is thrown. The thrown error has properties `missingRef` (with hash fragment) and `missingSchema` (without it). Both properties are resolved relative to the current base id (usually schema id, unless it was substituted).
- `"ignore"` - to log error during compilation and always pass validation.
- `"fail"` - to log error and successfully compile schema but fail validation if this rule is checked.
- _extendRefs_: validation of other keywords when `$ref` is present in the schema. Option values:
- `"ignore"` (default) - when `$ref` is used other keywords are ignored (as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03#section-3) standard). A warning will be logged during the schema compilation.
- `"fail"` (recommended) - if other validation keywords are used together with `$ref` the exception will be thrown when the schema is compiled. This option is recommended to make sure schema has no keywords that are ignored, which can be confusing.
- `true` - validate all keywords in the schemas with `$ref` (the default behaviour in versions before 5.0.0).
- _loadSchema_: asynchronous function that will be used to load remote schemas when `compileAsync` [method](#api-compileAsync) is used and some reference is missing (option `missingRefs` should NOT be 'fail' or 'ignore'). This function should accept remote schema uri as a parameter and return a Promise that resolves to a schema. See example in [Asynchronous compilation](#asynchronous-schema-compilation).
##### Options to modify validated data
- _removeAdditional_: remove additional properties - see example in [Filtering data](#filtering-data). This option is not used if schema is added with `addMetaSchema` method. Option values:
- `false` (default) - not to remove additional properties
- `"all"` - all additional properties are removed, regardless of `additionalProperties` keyword in schema (and no validation is made for them).
- `true` - only additional properties with `additionalProperties` keyword equal to `false` are removed.
- `"failing"` - additional properties that fail schema validation will be removed (where `additionalProperties` keyword is `false` or schema).
- _useDefaults_: replace missing or undefined properties and items with the values from corresponding `default` keywords. Default behaviour is to ignore `default` keywords. This option is not used if schema is added with `addMetaSchema` method. See examples in [Assigning defaults](#assigning-defaults). Option values:
- `false` (default) - do not use defaults
- `true` - insert defaults by value (object literal is used).
- `"empty"` - in addition to missing or undefined, use defaults for properties and items that are equal to `null` or `""` (an empty string).
- `"shared"` (deprecated) - insert defaults by reference. If the default is an object, it will be shared by all instances of validated data. If you modify the inserted default in the validated data, it will be modified in the schema as well.
- _coerceTypes_: change data type of data to match `type` keyword. See the example in [Coercing data types](#coercing-data-types) and [coercion rules](https://github.com/ajv-validator/ajv/blob/master/COERCION.md). Option values:
- `false` (default) - no type coercion.
- `true` - coerce scalar data types.
- `"array"` - in addition to coercions between scalar types, coerce scalar data to an array with one element and vice versa (as required by the schema).
##### Strict mode options
- _strictDefaults_: report ignored `default` keywords in schemas. Option values:
- `false` (default) - ignored defaults are not reported
- `true` - if an ignored default is present, throw an error
- `"log"` - if an ignored default is present, log warning
- _strictKeywords_: report unknown keywords in schemas. Option values:
- `false` (default) - unknown keywords are not reported
- `true` - if an unknown keyword is present, throw an error
- `"log"` - if an unknown keyword is present, log warning
- _strictNumbers_: validate numbers strictly, failing validation for NaN and Infinity. Option values:
- `false` (default) - NaN or Infinity will pass validation for numeric types
- `true` - NaN or Infinity will not pass validation for numeric types
##### Asynchronous validation options
- _transpile_: Requires [ajv-async](https://github.com/ajv-validator/ajv-async) package. It determines whether Ajv transpiles compiled asynchronous validation function. Option values:
- `undefined` (default) - transpile with [nodent](https://github.com/MatAtBread/nodent) if async functions are not supported.
- `true` - always transpile with nodent.
- `false` - do not transpile; if async functions are not supported an exception will be thrown.
##### Advanced options
- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword.
- _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can be http://json-schema.org/draft-07/schema or absent (draft-07 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values:
- `true` (default) - if the validation fails, throw the exception.
- `"log"` - if the validation fails, log error.
- `false` - skip schema validation.
- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method.
- _inlineRefs_: Affects compilation of referenced schemas. Option values:
- `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions.
- `false` - to not inline referenced schemas (they will be compiled as separate functions).
- integer number - to limit the maximum number of keywords of the schema that will be inlined.
- _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance.
- _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance.
- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst.
- _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/ajv-validator/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations).
- _errorDataPath_ (deprecated): set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`.
- _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/ajv-validator/ajv-i18n)).
- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call).
- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options:
- `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass a function calling `require('js-beautify').js_beautify` as `processCode: code => js_beautify(code)`.
- `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/ajv-validator/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information.
- _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`.
- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) is used.
## Validation errors
In case of validation failure, Ajv assigns the array of errors to `errors` property of validation function (or to `errors` property of Ajv instance when `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation), the returned promise is rejected with exception `Ajv.ValidationError` that has `errors` property.
### Error objects
Each error is an object with the following properties:
- _keyword_: validation keyword.
- _dataPath_: the path to the part of the data that was validated. By default `dataPath` uses JavaScript property access notation (e.g., `".prop[1].subProp"`). When the option `jsonPointers` is true (see [Options](#options)) `dataPath` will be set using JSON pointer standard (e.g., `"/prop/1/subProp"`).
- _schemaPath_: the path (JSON-pointer as a URI fragment) to the schema of the keyword that failed validation.
- _params_: the object with the additional information about error that can be used to create custom error messages (e.g., using [ajv-i18n](https://github.com/ajv-validator/ajv-i18n) package). See below for parameters set by all keywords.
- _message_: the standard error message (can be excluded with option `messages` set to false).
- _schema_: the schema of the keyword (added with `verbose` option).
- _parentSchema_: the schema containing the keyword (added with `verbose` option)
- _data_: the data validated by the keyword (added with `verbose` option).
__Please note__: `propertyNames` keyword schema validation errors have an additional property `propertyName`, `dataPath` points to the object. After schema validation for each property name, if it is invalid an additional error is added with the property `keyword` equal to `"propertyNames"`.
### Error parameters
Properties of `params` object in errors depend on the keyword that failed validation.
- `maxItems`, `minItems`, `maxLength`, `minLength`, `maxProperties`, `minProperties` - property `limit` (number, the schema of the keyword).
- `additionalItems` - property `limit` (the maximum number of allowed items in case when `items` keyword is an array of schemas and `additionalItems` is false).
- `additionalProperties` - property `additionalProperty` (the property not used in `properties` and `patternProperties` keywords).
- `dependencies` - properties:
- `property` (dependent property),
- `missingProperty` (required missing dependency - only the first one is reported currently)
- `deps` (required dependencies, comma separated list as a string),
- `depsCount` (the number of required dependencies).
- `format` - property `format` (the schema of the keyword).
- `maximum`, `minimum` - properties:
- `limit` (number, the schema of the keyword),
- `exclusive` (boolean, the schema of `exclusiveMaximum` or `exclusiveMinimum`),
- `comparison` (string, comparison operation to compare the data to the limit, with the data on the left and the limit on the right; can be "<", "<=", ">", ">=")
- `multipleOf` - property `multipleOf` (the schema of the keyword)
- `pattern` - property `pattern` (the schema of the keyword)
- `required` - property `missingProperty` (required property that is missing).
- `propertyNames` - property `propertyName` (an invalid property name).
- `patternRequired` (in ajv-keywords) - property `missingPattern` (required pattern that did not match any property).
- `type` - property `type` (required type(s), a string, can be a comma-separated list)
- `uniqueItems` - properties `i` and `j` (indices of duplicate items).
- `const` - property `allowedValue` pointing to the value (the schema of the keyword).
- `enum` - property `allowedValues` pointing to the array of values (the schema of the keyword).
- `$ref` - property `ref` with the referenced schema URI.
- `oneOf` - property `passingSchemas` (array of indices of passing schemas, null if no schema passes).
- custom keywords (in case keyword definition doesn't create errors) - property `keyword` (the keyword name).
### Error logging
Using the `logger` option when initiallizing Ajv will allow you to define custom logging. Here you can build upon the exisiting logging. The use of other logging packages is supported as long as the package or its associated wrapper exposes the required methods. If any of the required methods are missing an exception will be thrown.
- **Required Methods**: `log`, `warn`, `error`
```javascript
var otherLogger = new OtherLogger();
var ajv = new Ajv({
logger: {
log: console.log.bind(console),
warn: function warn() {
otherLogger.logWarn.apply(otherLogger, arguments);
},
error: function error() {
otherLogger.logError.apply(otherLogger, arguments);
console.error.apply(console, arguments);
}
}
});
```
## Plugins
Ajv can be extended with plugins that add custom keywords, formats or functions to process generated code. When such plugin is published as npm package it is recommended that it follows these conventions:
- it exports a function
- this function accepts ajv instance as the first parameter and returns the same instance to allow chaining
- this function can accept an optional configuration as the second parameter
If you have published a useful plugin please submit a PR to add it to the next section.

## Contributing
All validation functions are generated using doT templates in [dot](https://github.com/ajv-validator/ajv/tree/master/lib/dot) folder. Templates are precompiled so doT is not a run-time dependency.
`npm run build` - compiles templates to [dotjs](https://github.com/ajv-validator/ajv/tree/master/lib/dotjs) folder.
`npm run watch` - automatically compiles templates when files in dot folder change

#### Safer Node.js Buffer API
**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
**Uses the built-in implementation when available.**
## install
```
npm install safe-buffer
```
## usage
The goal of this package is to provide a safe replacement for the node.js `Buffer`.
It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
the top of your node.js modules:
```js
var Buffer = require('safe-buffer').Buffer
// Existing buffer code will continue to work without issues:
new Buffer('hey', 'utf8')
new Buffer([1, 2, 3], 'utf8')
new Buffer(obj)
new Buffer(16) // create an uninitialized buffer (potentially unsafe)
// But you can use these new explicit APIs to make clear what you want:
Buffer.from('hey', 'utf8') // convert from many types to a Buffer
Buffer.alloc(16) // create a zero-filled buffer (safe)
Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
```
## api
### Class Method: Buffer.from(array)
<!-- YAML
added: v3.0.0
-->
* `array` {Array}
Allocates a new `Buffer` using an `array` of octets.
```js
const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
// creates a new Buffer containing ASCII bytes
// ['b','u','f','f','e','r']
```
A `TypeError` will be thrown if `array` is not an `Array`.
### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
<!-- YAML
added: v5.10.0
-->
* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
a `new ArrayBuffer()`
* `byteOffset` {Number} Default: `0`
* `length` {Number} Default: `arrayBuffer.length - byteOffset`
When passed a reference to the `.buffer` property of a `TypedArray` instance,
the newly created `Buffer` will share the same allocated memory as the
TypedArray.
```js
const arr = new Uint16Array(2);
arr[0] = 5000;
arr[1] = 4000;
const buf = Buffer.from(arr.buffer); // shares the memory with arr;
console.log(buf);
// Prints: <Buffer 88 13 a0 0f>
// changing the TypedArray changes the Buffer also
arr[1] = 6000;
console.log(buf);
// Prints: <Buffer 88 13 70 17>
```
The optional `byteOffset` and `length` arguments specify a memory range within
the `arrayBuffer` that will be shared by the `Buffer`.
```js
const ab = new ArrayBuffer(10);
const buf = Buffer.from(ab, 0, 2);
console.log(buf.length);
// Prints: 2
```
A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
### Class Method: Buffer.from(buffer)
<!-- YAML
added: v3.0.0
-->
* `buffer` {Buffer}
Copies the passed `buffer` data onto a new `Buffer` instance.
```js
const buf1 = Buffer.from('buffer');
const buf2 = Buffer.from(buf1);
buf1[0] = 0x61;
console.log(buf1.toString());
// 'auffer'
console.log(buf2.toString());
// 'buffer' (copy is not changed)
```
A `TypeError` will be thrown if `buffer` is not a `Buffer`.
### Class Method: Buffer.from(str[, encoding])
<!-- YAML
added: v5.10.0
-->
* `str` {String} String to encode.
* `encoding` {String} Encoding to use, Default: `'utf8'`
Creates a new `Buffer` containing the given JavaScript string `str`. If
provided, the `encoding` parameter identifies the character encoding.
If not provided, `encoding` defaults to `'utf8'`.
```js
const buf1 = Buffer.from('this is a tést');
console.log(buf1.toString());
// prints: this is a tést
console.log(buf1.toString('ascii'));
// prints: this is a tC)st
const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
console.log(buf2.toString());
// prints: this is a tést
```
A `TypeError` will be thrown if `str` is not a string.
### Class Method: Buffer.alloc(size[, fill[, encoding]])
<!-- YAML
added: v5.10.0
-->
* `size` {Number}
* `fill` {Value} Default: `undefined`
* `encoding` {String} Default: `utf8`
Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
`Buffer` will be *zero-filled*.
```js
const buf = Buffer.alloc(5);
console.log(buf);
// <Buffer 00 00 00 00 00>
```
The `size` must be less than or equal to the value of
`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
be created if a `size` less than or equal to 0 is specified.
If `fill` is specified, the allocated `Buffer` will be initialized by calling
`buf.fill(fill)`. See [`buf.fill()`][] for more information.
```js
const buf = Buffer.alloc(5, 'a');
console.log(buf);
// <Buffer 61 61 61 61 61>
```
If both `fill` and `encoding` are specified, the allocated `Buffer` will be
initialized by calling `buf.fill(fill, encoding)`. For example:
```js
const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
console.log(buf);
// <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
```
Calling `Buffer.alloc(size)` can be significantly slower than the alternative
`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
contents will *never contain sensitive data*.
A `TypeError` will be thrown if `size` is not a number.
### Class Method: Buffer.allocUnsafe(size)
<!-- YAML
added: v5.10.0
-->
* `size` {Number}
Allocates a new *non-zero-filled* `Buffer` of `size` bytes. The `size` must
be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
thrown. A zero-length Buffer will be created if a `size` less than or equal to
0 is specified.
The underlying memory for `Buffer` instances created in this way is *not
initialized*. The contents of the newly created `Buffer` are unknown and
*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
`Buffer` instances to zeroes.
```js
const buf = Buffer.allocUnsafe(5);
console.log(buf);
// <Buffer 78 e0 82 02 01>
// (octets will be different, every time)
buf.fill(0);
console.log(buf);
// <Buffer 00 00 00 00 00>
```
A `TypeError` will be thrown if `size` is not a number.
Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
size `Buffer.poolSize` that is used as a pool for the fast allocation of new
`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
`new Buffer(size)` constructor) only when `size` is less than or equal to
`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
value of `Buffer.poolSize` is `8192` but can be modified.
Use of this pre-allocated internal memory pool is a key difference between
calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
difference is subtle but can be important when an application requires the
additional performance that `Buffer.allocUnsafe(size)` provides.
### Class Method: Buffer.allocUnsafeSlow(size)
<!-- YAML
added: v5.10.0
-->
* `size` {Number}
Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes. The
`size` must be less than or equal to the value of
`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
be created if a `size` less than or equal to 0 is specified.
The underlying memory for `Buffer` instances created in this way is *not
initialized*. The contents of the newly created `Buffer` are unknown and
*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
`Buffer` instances to zeroes.
When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
allocations under 4KB are, by default, sliced from a single pre-allocated
`Buffer`. This allows applications to avoid the garbage collection overhead of
creating many individually allocated Buffers. This approach improves both
performance and memory usage by eliminating the need to track and cleanup as
many `Persistent` objects.
However, in the case where a developer may need to retain a small chunk of
memory from a pool for an indeterminate amount of time, it may be appropriate
to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
copy out the relevant bits.
```js
// need to keep around a few small chunks of memory
const store = [];
socket.on('readable', () => {
const data = socket.read();
// allocate for retained data
const sb = Buffer.allocUnsafeSlow(10);
// copy the data into the new allocation
data.copy(sb, 0, 0, 10);
store.push(sb);
});
```
Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
a developer has observed undue memory retention in their applications.
A `TypeError` will be thrown if `size` is not a number.
### All the Rest
The rest of the `Buffer` API is exactly the same as in node.js.
[See the docs](https://nodejs.org/api/buffer.html).
## Related links
- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
## Why is `Buffer` unsafe?
Today, the node.js `Buffer` constructor is overloaded to handle many different argument
types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
`ArrayBuffer`, and also `Number`.
The API is optimized for convenience: you can throw any type at it, and it will try to do
what you want.
Because the Buffer constructor is so powerful, you often see code like this:
```js
// Convert UTF-8 strings to hex
function toHex (str) {
return new Buffer(str).toString('hex')
}
```
***But what happens if `toHex` is called with a `Number` argument?***
### Remote Memory Disclosure
If an attacker can make your program call the `Buffer` constructor with a `Number`
argument, then they can make it allocate uninitialized memory from the node.js process.
This could potentially disclose TLS private keys, user data, or database passwords.
When the `Buffer` constructor is passed a `Number` argument, it returns an
**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
this, you **MUST** overwrite the contents before returning it to the user.
From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
> `new Buffer(size)`
>
> - `size` Number
>
> The underlying memory for `Buffer` instances created in this way is not initialized.
> **The contents of a newly created `Buffer` are unknown and could contain sensitive
> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
(Emphasis our own.)
Whenever the programmer intended to create an uninitialized `Buffer` you often see code
like this:
```js
var buf = new Buffer(16)
// Immediately overwrite the uninitialized buffer with data from another buffer
for (var i = 0; i < buf.length; i++) {
buf[i] = otherBuf[i]
}
```
### Would this ever be a problem in real code?
Yes. It's surprisingly common to forget to check the type of your variables in a
dynamically-typed language like JavaScript.
Usually the consequences of assuming the wrong type is that your program crashes with an
uncaught exception. But the failure mode for forgetting to check the type of arguments to
the `Buffer` constructor is more catastrophic.
Here's an example of a vulnerable service that takes a JSON payload and converts it to
hex:
```js
// Take a JSON payload {str: "some string"} and convert it to hex
var server = http.createServer(function (req, res) {
var data = ''
req.setEncoding('utf8')
req.on('data', function (chunk) {
data += chunk
})
req.on('end', function () {
var body = JSON.parse(data)
res.end(new Buffer(body.str).toString('hex'))
})
})
server.listen(8080)
```
In this example, an http client just has to send:
```json
{
"str": 1000
}
```
and it will get back 1,000 bytes of uninitialized memory from the server.
This is a very serious bug. It's similar in severity to the
[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
memory by remote attackers.
### Which real-world packages were vulnerable?
#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
[Mathias Buus](https://github.com/mafintosh) and I
([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
Here's
[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
that fixed it. We released a new fixed version, created a
[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
vulnerable versions on npm so users will get a warning to upgrade to a newer version.
#### [`ws`](https://www.npmjs.com/package/ws)
That got us wondering if there were other vulnerable packages. Sure enough, within a short
period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
most popular WebSocket implementation in node.js.
If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
expected, then uninitialized server memory would be disclosed to the remote peer.
These were the vulnerable methods:
```js
socket.send(number)
socket.ping(number)
socket.pong(number)
```
Here's a vulnerable socket server with some echo functionality:
```js
server.on('connection', function (socket) {
socket.on('message', function (message) {
message = JSON.parse(message)
if (message.type === 'echo') {
socket.send(message.data) // send back the user's message
}
})
})
```
`socket.send(number)` called on the server, will disclose server memory.
Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
was fixed, with a more detailed explanation. Props to
[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
### What's the solution?
It's important that node.js offers a fast way to get memory otherwise performance-critical
applications would needlessly get a lot slower.
But we need a better way to *signal our intent* as programmers. **When we want
uninitialized memory, we should request it explicitly.**
Sensitive functionality should not be packed into a developer-friendly API that loosely
accepts many different types. This type of API encourages the lazy practice of passing
variables in without checking the type very carefully.
#### A new API: `Buffer.allocUnsafe(number)`
The functionality of creating buffers with uninitialized memory should be part of another
API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
frequently gets user input of all sorts of different types passed into it.
```js
var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
// Immediately overwrite the uninitialized buffer with data from another buffer
for (var i = 0; i < buf.length; i++) {
buf[i] = otherBuf[i]
}
```
### How do we fix node.js core?
We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
`semver-major`) which defends against one case:
```js
var str = 16
new Buffer(str, 'utf8')
```
In this situation, it's implied that the programmer intended the first argument to be a
string, since they passed an encoding as a second argument. Today, node.js will allocate
uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
what the programmer intended.
But this is only a partial solution, since if the programmer does `new Buffer(variable)`
(without an `encoding` parameter) there's no way to know what they intended. If `variable`
is sometimes a number, then uninitialized memory will sometimes be returned.
### What's the real long-term fix?
We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
we need uninitialized memory. But that would break 1000s of packages.
~~We believe the best solution is to:~~
~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
#### Update
We now support adding three new APIs:
- `Buffer.from(value)` - convert from any type to a buffer
- `Buffer.alloc(size)` - create a zero-filled buffer
- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
This solves the core problem that affected `ws` and `bittorrent-dht` which is
`Buffer(variable)` getting tricked into taking a number argument.
This way, existing code continues working and the impact on the npm ecosystem will be
minimal. Over time, npm maintainers can migrate performance-critical code to use
`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
### Conclusion
We think there's a serious design issue with the `Buffer` API as it exists today. It
promotes insecure software by putting high-risk functionality into a convenient API
with friendly "developer ergonomics".
This wasn't merely a theoretical exercise because we found the issue in some of the
most popular npm packages.
Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
`buffer`.
```js
var Buffer = require('safe-buffer').Buffer
```
Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
the impact on the ecosystem would be minimal since it's not a breaking change.
Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
older, insecure packages would magically become safe from this attack vector.

# assert-plus
This library is a super small wrapper over node's assert module that has two
things: (1) the ability to disable assertions with the environment variable
NODE\_NDEBUG, and (2) some API wrappers for argument testing. Like
`assert.string(myArg, 'myArg')`. As a simple example, most of my code looks
like this:
```javascript
var assert = require('assert-plus');
function fooAccount(options, callback) {
assert.object(options, 'options');
assert.number(options.id, 'options.id');
assert.bool(options.isManager, 'options.isManager');
assert.string(options.name, 'options.name');
assert.arrayOfString(options.email, 'options.email');
assert.func(callback, 'callback');
// Do stuff
callback(null, {});
}
```
# API
All methods that *aren't* part of node's core assert API are simply assumed to
take an argument, and then a string 'name' that's not a message; `AssertionError`
will be thrown if the assertion fails with a message like:
AssertionError: foo (string) is required
at test (/home/mark/work/foo/foo.js:3:9)
at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
at Module._compile (module.js:446:26)
at Object..js (module.js:464:10)
at Module.load (module.js:353:31)
at Function._load (module.js:311:12)
at Array.0 (module.js:484:10)
at EventEmitter._tickCallback (node.js:190:38)
from:
```javascript
function test(foo) {
assert.string(foo, 'foo');
}
```
There you go. You can check that arrays are of a homogeneous type with `Arrayof$Type`:
```javascript
function test(foo) {
assert.arrayOfString(foo, 'foo');
}
```
You can assert IFF an argument is not `undefined` (i.e., an optional arg):
```javascript
assert.optionalString(foo, 'foo');
```
Lastly, you can opt-out of assertion checking altogether by setting the
environment variable `NODE_NDEBUG=1`. This is pseudo-useful if you have
lots of assertions, and don't want to pay `typeof ()` taxes to v8 in
production. Be advised: The standard functions re-exported from `assert` are
also disabled in assert-plus if NDEBUG is specified. Using them directly from
the `assert` module avoids this behavior.

* assert.array
* assert.bool
* assert.buffer
* assert.func

Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
with the help of [many contributors](https://github.com/jquery/esprima/contributors).
### Features
- Full support for ECMAScript 2017 ([ECMA-262 8th Edition](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/es5.md) as standardized by [ESTree project](https://github.com/estree/estree)
- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
- Optional tracking of syntax node location (index-based and line-column)
- [Heavily tested](http://esprima.org/test/ci.html) (~1500 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
### API
Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
A simple example on Node.js REPL:
```javascript
> var esprima = require('esprima');
> var program = 'const answer = 42';
> esprima.tokenize(program);
[ { type: 'Keyword', value: 'const' },
{ type: 'Identifier', value: 'answer' },
{ type: 'Punctuator', value: '=' },
{ type: 'Numeric', value: '42' } ]
> esprima.parseScript(program);
{ type: 'Program',
body:
[ { type: 'VariableDeclaration',
declarations: [Object],
kind: 'const' } ],
sourceType: 'script' }
```

# node-dashdash changelog
## not yet released
(nothing yet)
## 1.14.1
- [issue #30] Change the output used by dashdash's Bash completion support to
indicate "there are no completions for this argument" to cope with different
sorting rules on different Bash/platforms. For example:
$ triton -v -p test2 package get <TAB> # before
##-no -tritonpackage- completions-##
$ triton -v -p test2 package get <TAB> # after
##-no-completion- -results-##
## 1.14.0
- New `synopsisFromOpt(<option spec>)` function. This will be used by
[node-cmdln](https://github.com/trentm/node-cmdln) to put together a synopsis
of options for a command. Some examples:
> synopsisFromOpt({names: ['help', 'h'], type: 'bool'});
'[ --help | -h ]'
> synopsisFromOpt({name: 'file', type: 'string', helpArg: 'FILE'});
'[ --file=FILE ]'
## 1.13.1
- [issue #20] `bashCompletionSpecFromOptions` breaks on an options array with
an empty-string group.
## 1.13.0
- Update assert-plus dep to 1.x to get recent fixes (particularly for
`assert.optional*`).
- Drop testing (and official support in packages.json#engines) for node 0.8.x.
Add testing against node 5.x and 4.x with `make testall`.
- [pull #16] Change the `positiveInteger` type to NOT accept zero (0).
For those who might need the old behaviour, see
"examples/custom-option-intGteZero.js". (By Dave Pacheco.)
## 1.12.2
- Bash completion: Add `argtypes` to specify the types of positional args.
E.g. this would allow you to have an `ssh` command with `argtypes = ['host',
'cmd']` for bash completion. You then have to provide Bash functions to
handle completing those types via the `specExtra` arg. See
"[examples/ddcompletion.js](examples/ddcompletion.js)" for an example.
- Bash completion: Tweak so that options or only offered as completions when
there is a leading '-'. E.g. `mytool <TAB>` does NOT offer options, `mytool
-<TAB>` *does*. Without this, a tool with options would never be able to
fallback to Bash's "default" completion. For example `ls <TAB>` wouldn't
result in filename completion. Now it will.
- Bash completion: A workaround for not being able to explicitly have *no*
completion results. Because dashdash's completion uses `complete -o default`,
we fallback to Bash's "default" completion (typically for filename
completion). Before this change, an attempt to explicitly say "there are
no completions that match" would unintentionally trigger filename completion.
Instead as a workaround we return:
$ ddcompletion --none <TAB> # the 'none' argtype
##-no completions-##
$ ddcompletion # a custom 'fruit' argtype
apple banana orange
$ ddcompletion z
##-no -fruit- completions-##
This is a bit of a hack, but IMO a better experience than the surprise
of matching a local filename beginning with 'z', which isn't, in this
case, a "fruit".
## 1.12.1
- Bash completion: Document `<option spec>.completionType`. Add `includeHidden`
option to `bashCompletionSpecFromOptions()`. Add support for dealing with
hidden subcmds.
## 1.12.0
- Support for generating Bash completion files. See the "Bash completion"
section of the README.md and "examples/ddcompletion.js" for an example.
## 1.11.0
- Add the `arrayFlatten` boolean option to `dashdash.addOptionType` used for
custom option types. This allows one to create an `arrayOf...` option type
where each usage of the option can return multiple results. For example:
node mytool.js --foo a,b --foo c
We could define an option type for `--foo` such that
`opts.foo = ['a', 'b', 'c']`. See
"[examples/custom-option-arrayOfCommaSepString.js](examples/custom-option-arrayOfCommaSepString.js)"
for an example.
## 1.10.1
- Trim the published package to the minimal bits. Before: 24K tarball, 144K unpacked.
After: 12K tarball, 48K unpacked. `npm` won't let me drop the README.md. :)
## 1.10.0
- [issue #9] Support `includeDefault` in help config (similar to `includeEnv`) to have a
note of an option's default value, if any, in help output.
- [issue #11] Fix option group breakage introduced in v1.9.0.
## 1.9.0
- [issue #10] Custom option types added with `addOptionType` can specify a
"default" value. See "examples/custom-option-fruit.js".
## 1.8.0
- Support `hidden: true` in an option spec to have help output exclude this
option.
## 1.7.3
- [issue #8] Fix parsing of a short option group when one of the
option takes an argument. For example, consider `tail` with
a `-f` boolean option and a `-n` option that takes a number
argument. This should parse:
tail -fn5
Before this change, that would not parse correctly.
It is suspected that this was introduced in version 1.4.0
(with commit 656fa8bc71c372ebddad0a7026bd71611e2ec99a).
## 1.7.2
- Known issues: #8
- Exclude 'tools/' dir in packages published to npm.
## 1.7.1
- Known issues: #8
- Support an option group *empty string* value:
...
{ group: '' },
...
to render as a blank line in option help. This can help separate loosely
related sets of options without resorting to a title for option groups.
## 1.7.0
- Known issues: #8
- [pull #7] Support for `<parser>.help({helpWrap: false, ...})` option to be able
to fully control the formatting for option help (by Patrick Mooney) `helpWrap:
false` can also be set on individual options in the option objects, e.g.:
var options = [
{
names: ['foo'],
type: 'string',
helpWrap: false,
help: 'long help with\n newlines' +
'\n spaces\n and such\nwill render correctly'
},
...
];
## 1.6.0
- Known issues: #8
- [pull #6] Support headings between groups of options (by Joshua M. Clulow)
so that this code:
var options = [
{ group: 'Armament Options' },
{ names: [ 'weapon', 'w' ], type: 'string' },
{ group: 'General Options' },
{ names: [ 'help', 'h' ], type: 'bool' }
];
...
will give you this help output:
...
Armament Options:
-w, --weapon
General Options:
-h, --help
...
## 1.5.0
- Known issues: #8
- Add support for adding custom option types. "examples/custom-option-duration.js"
shows an example adding a "duration" option type.
$ node custom-option-duration.js -t 1h
duration: 3600000 ms
$ node custom-option-duration.js -t 1s
duration: 1000 ms
$ node custom-option-duration.js -t 5d
duration: 432000000 ms
$ node custom-option-duration.js -t bogus
custom-option-duration.js: error: arg for "-t" is not a valid duration: "bogus"
A custom option type is added via:
var dashdash = require('dashdash');
dashdash.addOptionType({
name: '...',
takesArg: true,
helpArg: '...',
parseArg: function (option, optstr, arg) {
...
}
});
- [issue #4] Add `date` and `arrayOfDate` option types. They accept these date
formats: epoch second times (e.g. 1396031701) and ISO 8601 format:
`YYYY-MM-DD[THH:MM:SS[.sss][Z]]` (e.g. "2014-03-28",
"2014-03-28T18:35:01.489Z"). See "examples/date.js" for an example usage.
$ node examples/date.js -s 2014-01-01 -e $(date +%s)
start at 2014-01-01T00:00:00.000Z
end at 2014-03-29T04:26:18.000Z
## 1.4.0
- Known issues: #8
- [pull #2, pull #3] Add a `allowUnknown: true` option on `createParser` to
allow unknown options to be passed through as `opts._args` instead of parsing
throwing an exception (by https://github.com/isaacs).
See 'allowUnknown' in the README for a subtle caveat.
## 1.3.2
- Fix a subtlety where a *bool* option using both `env` and `default` didn't
work exactly correctly. If `default: false` then all was fine (by luck).
However, if you had an option like this:
options: [ {
names: ['verbose', 'v'],
env: 'FOO_VERBOSE',
'default': true, // <--- this
type: 'bool'
} ],
wanted `FOO_VERBOSE=0` to make the option false, then you need the fix
in this version of dashdash.
## 1.3.1
- [issue #1] Fix an envvar not winning over an option 'default'. Previously
an option with both `default` and `env` would never take a value from the
environment variable. E.g. `FOO_FILE` would never work here:
options: [ {
names: ['file', 'f'],
env: 'FOO_FILE',
'default': 'default.file',
type: 'string'
} ],
## 1.3.0
- [Backward incompatible change for boolean envvars] Change the
interpretation of environment variables for boolean options to consider '0'
to be false. Previous to this *any* value to the envvar was considered
true -- which was quite misleading. Example:
$ FOO_VERBOSE=0 node examples/foo.js
# opts: { verbose: [ false ],
_order: [ { key: 'verbose', value: false, from: 'env' } ],
_args: [] }
# args: []
## 1.2.1
- Fix for `parse.help({includeEnv: true, ...})` handling to ensure that an
option with an `env` **but no `help`** still has the "Environment: ..."
output. E.g.:
{ names: ['foo'], type: 'string', env: 'FOO' }
...
--foo=ARG Environment: FOO=ARG
## 1.2.0
- Transform the option key on the `opts` object returned from
`<parser>.parse()` for convenience. Currently this is just
`s/-/_/g`, e.g. '--dry-run' -> `opts.dry_run`. This allow one to use hyphen
in option names (common) but not have to do silly things like
`opt["dry-run"]` to access the parsed results.
## 1.1.0
- Environment variable integration. Envvars can be associated with an option,
then option processing will fallback to using that envvar if defined and
if the option isn't specified in argv. See the "Environment variable
integration" section in the README.
- Change the `<parser>.parse()` signature to take a single object with keys
for arguments. The old signature is still supported.
- `dashdash.createParser(CONFIG)` alternative to `new dashdash.Parser(CONFIG)`
a la many node-land APIs.
## 1.0.2
- Add "positiveInteger" and "arrayOfPositiveInteger" option types that only
accept positive integers.
- Add "integer" and "arrayOfInteger" option types that accepts only integers.
Note that, for better or worse, these do NOT accept: "0x42" (hex), "1e2"
(with exponent) or "1.", "3.0" (floats).
## 1.0.1
- Fix not modifying the given option spec objects (which breaks creating
a Parser with them more than once).
## 1.0.0
First release.
| zhihu-crawler | /zhihu_crawler-0.0.2.tar.gz/zhihu_crawler-0.0.2/zhihu_crawler/common/node_modules/dashdash/CHANGES.md | CHANGES.md |
A light, featureful and explicit option parsing library for node.js.
[Why another one? See below](#why). tl;dr: The others I've tried are one of
too loosey goosey (not explicit), too big/too many deps, or ill specified.
YMMV.
Follow <a href="https://twitter.com/intent/user?screen_name=trentmick" target="_blank">@trentmick</a>
for updates to node-dashdash.
# Install
npm install dashdash
# Usage
```javascript
var dashdash = require('dashdash');
// Specify the options. Minimally `name` (or `names`) and `type`
// must be given for each.
var options = [
{
// `names` or a single `name`. First element is the `opts.KEY`.
names: ['help', 'h'],
// See "Option specs" below for types.
type: 'bool',
help: 'Print this help and exit.'
}
];
// Shortcut form. As called it infers `process.argv`. See below for
// the longer form to use methods like `.help()` on the Parser object.
var opts = dashdash.parse({options: options});
console.log("opts:", opts);
console.log("args:", opts._args);
```
# Longer Example
A more realistic [starter script "foo.js"](./examples/foo.js) is as follows.
This also shows using `parser.help()` for formatted option help.
```javascript
var dashdash = require('dashdash');
var options = [
{
name: 'version',
type: 'bool',
help: 'Print tool version and exit.'
},
{
names: ['help', 'h'],
type: 'bool',
help: 'Print this help and exit.'
},
{
names: ['verbose', 'v'],
type: 'arrayOfBool',
help: 'Verbose output. Use multiple times for more verbose.'
},
{
names: ['file', 'f'],
type: 'string',
help: 'File to process',
helpArg: 'FILE'
}
];
var parser = dashdash.createParser({options: options});
try {
var opts = parser.parse(process.argv);
} catch (e) {
console.error('foo: error: %s', e.message);
process.exit(1);
}
console.log("# opts:", opts);
console.log("# args:", opts._args);
// Use `parser.help()` for formatted options help.
if (opts.help) {
var help = parser.help({includeEnv: true}).trimRight();
console.log('usage: node foo.js [OPTIONS]\n'
+ 'options:\n'
+ help);
process.exit(0);
}
// ...
```
Some example output from this script (foo.js):
```
$ node foo.js -h
# opts: { help: true,
_order: [ { name: 'help', value: true, from: 'argv' } ],
_args: [] }
# args: []
usage: node foo.js [OPTIONS]
options:
--version Print tool version and exit.
-h, --help Print this help and exit.
-v, --verbose Verbose output. Use multiple times for more verbose.
-f FILE, --file=FILE File to process
$ node foo.js -v
# opts: { verbose: [ true ],
_order: [ { name: 'verbose', value: true, from: 'argv' } ],
_args: [] }
# args: []
$ node foo.js --version arg1
# opts: { version: true,
_order: [ { name: 'version', value: true, from: 'argv' } ],
_args: [ 'arg1' ] }
# args: [ 'arg1' ]
$ node foo.js -f bar.txt
# opts: { file: 'bar.txt',
_order: [ { name: 'file', value: 'bar.txt', from: 'argv' } ],
_args: [] }
# args: []
$ node foo.js -vvv --file=blah
# opts: { verbose: [ true, true, true ],
file: 'blah',
_order:
[ { name: 'verbose', value: true, from: 'argv' },
{ name: 'verbose', value: true, from: 'argv' },
{ name: 'verbose', value: true, from: 'argv' },
{ name: 'file', value: 'blah', from: 'argv' } ],
_args: [] }
# args: []

some of dashdash's features.
# Environment variable integration
If you want to allow environment variables to specify options to your tool,
dashdash makes this easy. We can change the 'verbose' option in the example
above to include an 'env' field:
```javascript
{
names: ['verbose', 'v'],
type: 'arrayOfBool',
env: 'FOO_VERBOSE', // <--- add this line
help: 'Verbose output. Use multiple times for more verbose.'
},
```
then the **"FOO_VERBOSE" environment variable** can be used to set this
option:
```shell
$ FOO_VERBOSE=1 node foo.js
# opts: { verbose: [ true ],
_order: [ { name: 'verbose', value: true, from: 'env' } ],
_args: [] }
# args: []
```
Boolean options will interpret the empty string as unset, '0' as false
and anything else as true.
```shell
$ FOO_VERBOSE= node examples/foo.js # not set
# opts: { _order: [], _args: [] }
# args: []
$ FOO_VERBOSE=0 node examples/foo.js # '0' is false
# opts: { verbose: [ false ],
_order: [ { key: 'verbose', value: false, from: 'env' } ],
_args: [] }
# args: []
$ FOO_VERBOSE=1 node examples/foo.js # true
# opts: { verbose: [ true ],
_order: [ { key: 'verbose', value: true, from: 'env' } ],
_args: [] }
# args: []
$ FOO_VERBOSE=boogabooga node examples/foo.js # true
# opts: { verbose: [ true ],
_order: [ { key: 'verbose', value: true, from: 'env' } ],
_args: [] }
# args: []
```
Non-booleans can be used as well. Strings:
```shell
$ FOO_FILE=data.txt node examples/foo.js
# opts: { file: 'data.txt',
_order: [ { key: 'file', value: 'data.txt', from: 'env' } ],
_args: [] }
# args: []
```
Numbers:
```shell
$ FOO_TIMEOUT=5000 node examples/foo.js
# opts: { timeout: 5000,
_order: [ { key: 'timeout', value: 5000, from: 'env' } ],
_args: [] }
# args: []
$ FOO_TIMEOUT=blarg node examples/foo.js
foo: error: arg for "FOO_TIMEOUT" is not a positive integer: "blarg"
```
With the `includeEnv: true` config to `parser.help()` the environment
variable can also be included in **help output**:
usage: node foo.js [OPTIONS]
options:
--version Print tool version and exit.
-h, --help Print this help and exit.
-v, --verbose Verbose output. Use multiple times for more verbose.
Environment: FOO_VERBOSE=1
-f FILE, --file=FILE File to process
# Bash completion
Dashdash provides a simple way to create a Bash completion file that you
can place in your "bash_completion.d" directory -- sometimes that is
"/usr/local/etc/bash_completion.d/"). Features:
- Support for short and long opts
- Support for knowing which options take arguments
- Support for subcommands (e.g. 'git log <TAB>' to show just options for the
log subcommand). See
[node-cmdln](https://github.com/trentm/node-cmdln#bash-completion) for
how to integrate that.
- Does the right thing with "--" to stop options.
- Custom optarg and arg types for custom completions.
Dashdash will return bash completion file content given a parser instance:
var parser = dashdash.createParser({options: options});
console.log( parser.bashCompletion({name: 'mycli'}) );
or directly from a `options` array of options specs:
var code = dashdash.bashCompletionFromOptions({
name: 'mycli',
options: OPTIONS
});
Write that content to "/usr/local/etc/bash_completion.d/mycli" and you will
have Bash completions for `mycli`. Alternatively you can write it to
any file (e.g. "~/.bashrc") and source it.
You could add a `--completion` hidden option to your tool that emits the
completion content and document for your users to call that to install
Bash completions.
See [examples/ddcompletion.js](examples/ddcompletion.js) for a complete
example, including how one can define bash functions for completion of custom
option types. Also see [node-cmdln](https://github.com/trentm/node-cmdln) for
how it uses this for Bash completion for full multi-subcommand tools.

# Parser config
Parser construction (i.e. `dashdash.createParser(CONFIG)`) takes the
following fields:
- `options` (Array of option specs). Required. See the
[Option specs](#option-specs) section below.
- `interspersed` (Boolean). Optional. Default is true. If true this allows
interspersed arguments and options. I.e.:
node ./tool.js -v arg1 arg2 -h # '-h' is after interspersed args
Set it to false to have '-h' **not** get parsed as an option in the above
example.
- `allowUnknown` (Boolean). Optional. Default is false. If false, this causes
unknown arguments to throw an error. I.e.:
node ./tool.js -v arg1 --afe8asefksjefhas
Set it to true to treat the unknown option as a positional
argument.
**Caveat**: When a shortopt group, such as `-xaz` contains a mix of
known and unknown options, the *entire* group is passed through
unmolested as a positional argument.
Consider if you have a known short option `-a`, and parse the
following command line:
node ./tool.js -xaz
where `-x` and `-z` are unknown. There are multiple ways to
interpret this:
1. `-x` takes a value: `{x: 'az'}`
2. `-x` and `-z` are both booleans: `{x:true,a:true,z:true}`
Since dashdash does not know what `-x` and `-z` are, it can't know
if you'd prefer to receive `{a:true,_args:['-x','-z']}` or
`{x:'az'}`, or `{_args:['-xaz']}`. Leaving the positional arg unprocessed
is the easiest mistake for the user to recover from.
# Option specs
Example using all fields (required fields are noted):
```javascript
{
names: ['file', 'f'], // Required (one of `names` or `name`).
type: 'string', // Required.
completionType: 'filename',
env: 'MYTOOL_FILE',
help: 'Config file to load before running "mytool"',
helpArg: 'PATH',
helpWrap: false,
default: path.resolve(process.env.HOME, '.mytoolrc')
}
```
Each option spec in the `options` array must/can have the following fields:
- `name` (String) or `names` (Array). Required. These give the option name
and aliases. The first name (if more than one given) is the key for the
parsed `opts` object.
- `type` (String). Required. One of:
- bool
- string
- number
- integer
- positiveInteger
- date (epoch seconds, e.g. 1396031701, or ISO 8601 format
`YYYY-MM-DD[THH:MM:SS[.sss][Z]]`, e.g. "2014-03-28T18:35:01.489Z")
- arrayOfBool
- arrayOfString
- arrayOfNumber
- arrayOfInteger
- arrayOfPositiveInteger
- arrayOfDate
FWIW, these names attempt to match with asserts on
[assert-plus](https://github.com/mcavage/node-assert-plus).
You can add your own custom option types with `dashdash.addOptionType`.
See below.
- `completionType` (String). Optional. This is used for [Bash
completion](#bash-completion) for an option argument. If not specified,
then the value of `type` is used. Any string may be specified, but only the
following values have meaning:
- `none`: Provide no completions.
- `file`: Bash's default completion (i.e. `complete -o default`), which
includes filenames.
- *Any string FOO for which a `function complete_FOO` Bash function is
defined.* This is for custom completions for a given tool. Typically
these custom functions are provided in the `specExtra` argument to
`dashdash.bashCompletionFromOptions()`. See
["examples/ddcompletion.js"](examples/ddcompletion.js) for an example.
- `env` (String or Array of String). Optional. An environment variable name
(or names) that can be used as a fallback for this option. For example,
given a "foo.js" like this:
var options = [{names: ['dry-run', 'n'], env: 'FOO_DRY_RUN'}];
var opts = dashdash.parse({options: options});
Both `node foo.js --dry-run` and `FOO_DRY_RUN=1 node foo.js` would result
in `opts.dry_run = true`.
An environment variable is only used as a fallback, i.e. it is ignored if
the associated option is given in `argv`.
- `help` (String). Optional. Used for `parser.help()` output.
- `helpArg` (String). Optional. Used in help output as the placeholder for
the option argument, e.g. the "PATH" in:
...
-f PATH, --file=PATH File to process
...
- `helpWrap` (Boolean). Optional, default true. Set this to `false` to have
that option's `help` *not* be text wrapped in `<parser>.help()` output.
- `default`. Optional. A default value used for this option, if the
option isn't specified in argv.
- `hidden` (Boolean). Optional, default false. If true, help output will not
include this option. See also the `includeHidden` option to
`bashCompletionFromOptions()` for [Bash completion](#bash-completion).
# Option group headings
You can add headings between option specs in the `options` array. To do so,
simply add an object with only a `group` property -- the string to print as
the heading for the subsequent options in the array. For example:
```javascript
var options = [
{
group: 'Armament Options'
},
{
names: [ 'weapon', 'w' ],
type: 'string'
},
{
group: 'General Options'
},
{
names: [ 'help', 'h' ],
type: 'bool'
}
];
...
```
Note: You can use an empty string, `{group: ''}`, to get a blank line in help
output between groups of options.
# Help config
The `parser.help(...)` function is configurable as follows:
Options:
Armament Options:
^^ -w WEAPON, --weapon=WEAPON Weapon with which to crush. One of: |
/ sword, spear, maul |
/ General Options: |
/ -h, --help Print this help and exit. |
/ ^^^^ ^ |
\ `-- indent `-- helpCol maxCol ---'
`-- headingIndent
- `indent` (Number or String). Default 4. Set to a number (for that many
spaces) or a string for the literal indent.
- `headingIndent` (Number or String). Default half length of `indent`. Set to
a number (for that many spaces) or a string for the literal indent. This
indent applies to group heading lines, between normal option lines.
- `nameSort` (String). Default is 'length'. By default the names are
sorted to put the short opts first (i.e. '-h, --help' preferred
to '--help, -h'). Set to 'none' to not do this sorting.
- `maxCol` (Number). Default 80. Note that reflow is just done on whitespace
so a long token in the option help can overflow maxCol.
- `helpCol` (Number). If not set a reasonable value will be determined
between `minHelpCol` and `maxHelpCol`.
- `minHelpCol` (Number). Default 20.
- `maxHelpCol` (Number). Default 40.
- `helpWrap` (Boolean). Default true. Set to `false` to have option `help`
strings *not* be textwrapped to the helpCol..maxCol range.
- `includeEnv` (Boolean). Default false. If the option has associated
environment variables (via the `env` option spec attribute), then
append mentioned of those envvars to the help string.
- `includeDefault` (Boolean). Default false. If the option has a default value
(via the `default` option spec attribute, or a default on the option's type),
then a "Default: VALUE" string will be appended to the help string.
# Custom option types
Dashdash includes a good starter set of option types that it will parse for
you. However, you can add your own via:
var dashdash = require('dashdash');
dashdash.addOptionType({
name: '...',
takesArg: true,
helpArg: '...',
parseArg: function (option, optstr, arg) {
...
},
array: false, // optional
arrayFlatten: false, // optional
default: ..., // optional
completionType: ... // optional
});
For example, a simple option type that accepts 'yes', 'y', 'no' or 'n' as
a boolean argument would look like:
var dashdash = require('dashdash');
function parseYesNo(option, optstr, arg) {
var argLower = arg.toLowerCase()
if (~['yes', 'y'].indexOf(argLower)) {
return true;
} else if (~['no', 'n'].indexOf(argLower)) {
return false;
} else {
throw new Error(format(
'arg for "%s" is not "yes" or "no": "%s"',
optstr, arg));
}
}
dashdash.addOptionType({
name: 'yesno'
takesArg: true,
helpArg: '<yes|no>',
parseArg: parseYesNo
});
var options = {
{names: ['answer', 'a'], type: 'yesno'}
};
var opts = dashdash.parse({options: options});
See "examples/custom-option-\*.js" for other examples.
See the `addOptionType` block comment in "lib/dashdash.js" for more details.
Please let me know [with an
issue](https://github.com/trentm/node-dashdash/issues/new) if you write a
generally useful one.
# Why
Why another node.js option parsing lib?
- `nopt` really is just for "tools like npm". Implicit opts (e.g. '--no-foo'
works for every '--foo'). Can't disable abbreviated opts. Can't do multiple
usages of same opt, e.g. '-vvv' (I think). Can't do grouped short opts.
- `optimist` has surprise interpretation of options (at least to me).
Implicit opts mean ambiguities and poor error handling for fat-fingering.
`process.exit` calls makes it hard to use as a libary.
- `optparse` Incomplete docs. Is this an attempted clone of Python's `optparse`.
Not clear. Some divergence. `parser.on("name", ...)` API is weird.
- `argparse` Dep on underscore. No thanks just for option processing.
`find lib | wc -l` -> `26`. Overkill.
Argparse is a bit different anyway. Not sure I want that.
- `posix-getopt` No type validation. Though that isn't a killer. AFAIK can't
have a long opt without a short alias. I.e. no `getopt_long` semantics.
Also, no whizbang features like generated help output.
- ["commander.js"](https://github.com/visionmedia/commander.js): I wrote
[a critique](http://trentm.com/2014/01/a-critique-of-commander-for-nodejs.html)
a while back. It seems fine, but last I checked had
[an outstanding bug](https://github.com/visionmedia/commander.js/pull/121)
that would prevent me from using it.

### Estraverse [](http://travis-ci.org/estools/estraverse)
Estraverse ([estraverse](http://github.com/estools/estraverse)) is
[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
traversal functions from [esmangle project](http://github.com/estools/esmangle).
### Documentation
You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
### Example Usage
The following code will output all variables declared at the root of a file.
```javascript
estraverse.traverse(ast, {
enter: function (node, parent) {
if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
return estraverse.VisitorOption.Skip;
},
leave: function (node, parent) {
if (node.type == 'VariableDeclarator')
console.log(node.id.name);
}
});
```
We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
```javascript
estraverse.traverse(ast, {
enter: function (node) {
this.break();
}
});
```
And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
```javascript
result = estraverse.replace(tree, {
enter: function (node) {
// Replace it with replaced.
if (node.type === 'Literal')
return replaced;
}
});
```
By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
```javascript
// This tree contains a user-defined `TestExpression` node.
var tree = {
type: 'TestExpression',
// This 'argument' is the property containing the other **node**.
argument: {
type: 'Literal',
value: 20
},
// This 'extended' is the property not containing the other **node**.
extended: true
};
estraverse.traverse(tree, {
enter: function (node) { },
// Extending the existing traversing rules.
keys: {
// TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
TestExpression: ['argument']
}
});
```
By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
```javascript
// This tree contains a user-defined `TestExpression` node.
var tree = {
type: 'TestExpression',
// This 'argument' is the property containing the other **node**.
argument: {
type: 'Literal',
value: 20
},
// This 'extended' is the property not containing the other **node**.
extended: true
};
estraverse.traverse(tree, {
enter: function (node) { },
// Iterating the child **nodes** of unknown nodes.
fallback: 'iteration'
});
```
When `visitor.fallback` is a function, we can determine which keys to visit on each node.
```javascript
// This tree contains a user-defined `TestExpression` node.
var tree = {
type: 'TestExpression',
// This 'argument' is the property containing the other **node**.
argument: {
type: 'Literal',
value: 20
},
// This 'extended' is the property not containing the other **node**.
extended: true
};
estraverse.traverse(tree, {
enter: function (node) { },
// Skip the `argument` property of each node
fallback: function(node) {
return Object.keys(node).filter(function(key) {
return key !== 'argument';
});
}
});
```

A querystring parsing and stringifying library with some added security.
Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
## Usage
```javascript
var qs = require('qs');
var assert = require('assert');
var obj = qs.parse('a=c');
assert.deepEqual(obj, { a: 'c' });
var str = qs.stringify(obj);
assert.equal(str, 'a=c');
```
### Parsing Objects
[](#preventEval)
```javascript
qs.parse(string, [options]);
```
**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
For example, the string `'foo[bar]=baz'` converts to:
```javascript
assert.deepEqual(qs.parse('foo[bar]=baz'), {
foo: {
bar: 'baz'
}
});
```
When using the `plainObjects` option the parsed value is returned as a null object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
```javascript
var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
```
By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
```javascript
var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
```
URI encoded strings work too:
```javascript
assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
a: { b: 'c' }
});
```
You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
```javascript
assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
foo: {
bar: {
baz: 'foobarbaz'
}
}
});
```
By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
```javascript
var expected = {
a: {
b: {
c: {
d: {
e: {
f: {
'[g][h][i]': 'j'
}
}
}
}
}
}
};
var string = 'a[b][c][d][e][f][g][h][i]=j';
assert.deepEqual(qs.parse(string), expected);
```
This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
```javascript
var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
```
The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
```javascript
var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
assert.deepEqual(limited, { a: 'b' });
```
To bypass the leading question mark, use `ignoreQueryPrefix`:
```javascript
var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
assert.deepEqual(prefixed, { a: 'b', c: 'd' });
```
An optional delimiter can also be passed:
```javascript
var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
assert.deepEqual(delimited, { a: 'b', c: 'd' });
```
Delimiters can be a regular expression too:
```javascript
var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
```
Option `allowDots` can be used to enable dot notation:
```javascript
var withDots = qs.parse('a.b=c', { allowDots: true });
assert.deepEqual(withDots, { a: { b: 'c' } });
```
### Parsing Arrays
**qs** can also parse arrays using a similar `[]` notation:
```javascript
var withArray = qs.parse('a[]=b&a[]=c');
assert.deepEqual(withArray, { a: ['b', 'c'] });
```
You may specify an index as well:
```javascript
var withIndexes = qs.parse('a[1]=c&a[0]=b');
assert.deepEqual(withIndexes, { a: ['b', 'c'] });
```
Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
their order:
```javascript
var noSparse = qs.parse('a[1]=b&a[15]=c');
assert.deepEqual(noSparse, { a: ['b', 'c'] });
```
Note that an empty string is also a value, and will be preserved:
```javascript
var withEmptyString = qs.parse('a[]=&a[]=b');
assert.deepEqual(withEmptyString, { a: ['', 'b'] });
var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
```
**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
instead be converted to an object with the index as the key:
```javascript
var withMaxIndex = qs.parse('a[100]=b');
assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
```
This limit can be overridden by passing an `arrayLimit` option:
```javascript
var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
```
To disable array parsing entirely, set `parseArrays` to `false`.
```javascript
var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
```
If you mix notations, **qs** will merge the two items into an object:
```javascript
var mixedNotation = qs.parse('a[0]=b&a[b]=c');
assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
```
You can also create arrays of objects:
```javascript
var arraysOfObjects = qs.parse('a[][b]=c');
assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
```
### Stringifying
[](#preventEval)
```javascript
qs.stringify(object, [options]);
```
When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
```javascript
assert.equal(qs.stringify({ a: 'b' }), 'a=b');
assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
```
This encoding can be disabled by setting the `encode` option to `false`:
```javascript
var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
assert.equal(unencoded, 'a[b]=c');
```
Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
```javascript
var encodedValues = qs.stringify(
{ a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
{ encodeValuesOnly: true }
);
assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
```
This encoding can also be replaced by a custom encoding method set as `encoder` option:
```javascript
var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
// Passed in values `a`, `b`, `c`
return // Return encoded string
}})
```
_(Note: the `encoder` option does not apply if `encode` is `false`)_
Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
```javascript
var decoded = qs.parse('x=z', { decoder: function (str) {
// Passed in values `x`, `z`
return // Return decoded string
}})
```
Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
When arrays are stringified, by default they are given explicit indices:
```javascript
qs.stringify({ a: ['b', 'c', 'd'] });
// 'a[0]=b&a[1]=c&a[2]=d'
```
You may override this by setting the `indices` option to `false`:
```javascript
qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
// 'a=b&a=c&a=d'
```
You may use the `arrayFormat` option to specify the format of the output array:
```javascript
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
// 'a[0]=b&a[1]=c'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
// 'a[]=b&a[]=c'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
// 'a=b&a=c'
```
When objects are stringified, by default they use bracket notation:
```javascript
qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
// 'a[b][c]=d&a[b][e]=f'
```
You may override this to use dot notation by setting the `allowDots` option to `true`:
```javascript
qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
// 'a.b.c=d&a.b.e=f'
```
Empty strings and null values will omit the value, but the equals sign (=) remains in place:
```javascript
assert.equal(qs.stringify({ a: '' }), 'a=');
```
Key with no values (such as an empty object or array) will return nothing:
```javascript
assert.equal(qs.stringify({ a: [] }), '');
assert.equal(qs.stringify({ a: {} }), '');
assert.equal(qs.stringify({ a: [{}] }), '');
assert.equal(qs.stringify({ a: { b: []} }), '');
assert.equal(qs.stringify({ a: { b: {}} }), '');
```
Properties that are set to `undefined` will be omitted entirely:
```javascript
assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
```
The query string may optionally be prepended with a question mark:
```javascript
assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
```
The delimiter may be overridden with stringify as well:
```javascript
assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
```
If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
```javascript
var date = new Date(7);
assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
assert.equal(
qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
'a=7'
);
```
You may use the `sort` option to affect the order of parameter keys:
```javascript
function alphabeticalSort(a, b) {
return a.localeCompare(b);
}
assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
```
Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
pass an array, it will be used to select properties and array indices for stringification:
```javascript
function filterFunc(prefix, value) {
if (prefix == 'b') {
// Return an `undefined` value to omit a property.
return;
}
if (prefix == 'e[f]') {
return value.getTime();
}
if (prefix == 'e[g][0]') {
return value * 2;
}
return value;
}
qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
// 'a=b&c=d&e[f]=123&e[g][0]=4'
qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
// 'a=b&e=f'
qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
// 'a[0]=b&a[2]=d'
```
### Handling of `null` values
By default, `null` values are treated like empty strings:
```javascript
var withNull = qs.stringify({ a: null, b: '' });
assert.equal(withNull, 'a=&b=');
```
Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
```javascript
var equalsInsensitive = qs.parse('a&b=');
assert.deepEqual(equalsInsensitive, { a: '', b: '' });
```
To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
values have no `=` sign:
```javascript
var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
assert.equal(strictNull, 'a&b=');
```
To parse values without `=` back to `null` use the `strictNullHandling` flag:
```javascript
var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
assert.deepEqual(parsedStrictNull, { a: null, b: '' });
```
To completely skip rendering keys with `null` values, use the `skipNulls` flag:
```javascript
var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
assert.equal(nullsSkipped, 'a=b');
```
### Dealing with special character sets
By default the encoding and decoding of characters is done in `utf-8`. If you
wish to encode querystrings to a different character set (i.e.
[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
```javascript
var encoder = require('qs-iconv/encoder')('shift_jis');
var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
```
This also works for decoding of query strings:
```javascript
var decoder = require('qs-iconv/decoder')('shift_jis');
var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
assert.deepEqual(obj, { a: 'こんにちは！' });
```
### RFC 3986 and RFC 1738 space encoding
RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
```
assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
```

# Punycode.js [](https://travis-ci.org/bestiejs/punycode.js) [](https://codecov.io/gh/bestiejs/punycode.js) [](https://gemnasium.com/bestiejs/punycode.js)
Punycode.js is a robust Punycode converter that fully complies to [RFC 3492](https://tools.ietf.org/html/rfc3492) and [RFC 5891](https://tools.ietf.org/html/rfc5891).
This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
* [The C example code from RFC 3492](https://tools.ietf.org/html/rfc3492#appendix-C)
* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
This project was [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with Node.js from [v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc) until [v7](https://github.com/nodejs/node/pull/7941) (soft-deprecated).
The current version supports recent versions of Node.js only. It provides a CommonJS module and an ES6 module. For the old version that offers the same functionality with broader support, including Rhino, Ringo, Narwhal, and web browsers, see [v1.4.1](https://github.com/bestiejs/punycode.js/releases/tag/v1.4.1).
## Installation
Via [npm](https://www.npmjs.com/):
```bash
npm install punycode --save
```
In [Node.js](https://nodejs.org/):
```js
const punycode = require('punycode');
```
## API
### `punycode.decode(string)`
Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
```js
// decode domain name parts
punycode.decode('maana-pta'); // 'mañana'
punycode.decode('--dqo34k'); // '☃-⌘'
```
### `punycode.encode(string)`
Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
```js
// encode domain name parts
punycode.encode('mañana'); // 'maana-pta'
punycode.encode('☃-⌘'); // '--dqo34k'
```
### `punycode.toUnicode(input)`
Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
```js
// decode domain names
punycode.toUnicode('xn--maana-pta.com');
// → 'mañana.com'
punycode.toUnicode('xn----dqo34k.com');
// → '☃-⌘.com'
// decode email addresses
punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
// → 'джумла@джpумлатест.bрфa'
```
### `punycode.toASCII(input)`
Converts a lowercased Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that’s already in ASCII.
```js
// encode domain names
punycode.toASCII('mañana.com');
// → 'xn--maana-pta.com'
punycode.toASCII('☃-⌘.com');
// → 'xn----dqo34k.com'
// encode email addresses
punycode.toASCII('джумла@джpумлатест.bрфa');
// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
```
### `punycode.ucs2`
#### `punycode.ucs2.decode(string)`
Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
```js
punycode.ucs2.decode('abc');
// → [0x61, 0x62, 0x63]
// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
punycode.ucs2.decode('\uD834\uDF06');
// → [0x1D306]
```
#### `punycode.ucs2.encode(codePoints)`
Creates a string based on an array of numeric code point values.
```js
punycode.ucs2.encode([0x61, 0x62, 0x63]);
// → 'abc'
punycode.ucs2.encode([0x1D306]);
// → '\uD834\uDF06'
```
### `punycode.version`
A string representing the current Punycode.js version number.
