LoadJS is a tiny async loader for modern browsers (899 bytes).

## Introduction
LoadJS is a tiny async loading library for modern browsers (IE9+). It has a simple yet powerful dependency management system that lets you fetch JavaScript, CSS and image files in parallel and execute code after the dependencies have been met. The recommended way to use LoadJS is to include the minified source code of [loadjs.js](https://raw.githubusercontent.com/muicss/loadjs/master/dist/loadjs.min.js) in your <html> (possibly in the <head> tag) and then use the `loadjs` global to manage JavaScript dependencies after pageload.
LoadJS is based on the excellent <a href="https://github.com/ded/script.js">$script</a> library by <a href="https://github.com/ded">Dustin Diaz</a>. We kept the behavior of the library the same but we re-wrote the code from scratch to add support for error callbacks and to optimize the library for modern browsers. Currently, LoadJS is 590 bytes (minified + gzipped).
## Browser Support
* IE9+
loadjs.ready('foobar', function() {
/* foo.js & bar.js loaded */
});
</script>
```
You can also use more advanced syntax for more options:
```html
<script src="//unpkg.com/loadjs@latest/dist/loadjs.min.js"></script>
<script>
// define a dependency bundle with advanced options
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', {
before: function(path, scriptEl) { /* execute code before fetch */ },
async: true, // load files synchronously or asynchronously (default: true)
numRetries: 3 // see caveats about using numRetries with async:false (default: 0),
returnPromise: false // return Promise object (default: false)
});
loadjs.ready('foobar', {
success: function() { /* foo.js & bar.js loaded */ },
error: function(depsNotFound) { /* foobar bundle load failed */ },
});
</script>
```
The latest version of LoadJS can be found in the `dist/` directory in this repository:
* [https://cdn.rawgit.com/muicss/loadjs/4.2.0/dist/loadjs.js](https://cdn.rawgit.com/muicss/loadjs/4.2.0/dist/loadjs.js) (for development)
* [https://cdn.rawgit.com/muicss/loadjs/4.2.0/dist/loadjs.min.js](https://cdn.rawgit.com/muicss/loadjs/4.2.0/dist/loadjs.min.js) (for production)
It's also available from these public CDNs:
* UNPKG
* [https://unpkg.com/[email protected]/dist/loadjs.js](https://unpkg.com/[email protected]/dist/loadjs.js) (for development)
* [https://unpkg.com/[email protected]/dist/loadjs.min.js](https://unpkg.com/[email protected]/dist/loadjs.min.js) (for production)
* CDNJS
* [https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.2.0/loadjs.js](https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.2.0/loadjs.js) (for development)
* [https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.2.0/loadjs.min.js](https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.2.0/loadjs.min.js) (for production)
You can also use it as a CJS or AMD module:
```bash
$ npm install --save loadjs
```
```javascript
var loadjs = require('loadjs');
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');
loadjs.ready('foobar', function() {
/* foo.js & bar.js loaded */
});
```
## Browser Support
* IE9+ (`async: false` support only works in IE10+)
* Opera 12+
* Safari 5+
* Chrome
* Firefox
* iOS 6+
* Android 4.4+
LoadJS also detects script load failures from AdBlock Plus and Ghostery in:
* Safari
* Chrome
Note: LoadJS treats empty CSS files as load failures in IE9-11 and uses `rel="preload"` to load CSS files in Edge (to get around lack of support for onerror events on `<link rel="stylesheet">` tags)
## Documentation
1. Load a single file
```javascript
loadjs('/path/to/foo.js', function() {
/* foo.js loaded */
});
```
1. Fetch files in parallel and load them asynchronously
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], function() {
/* foo.js and bar.js loaded */
});
```
1. Fetch JavaScript, CSS and image files
```javascript
loadjs(['/path/to/foo.css', '/path/to/bar.png', 'path/to/thunk.js'], function() {
/* foo.css, bar.png and thunk.js loaded */
});
```
1. Force treat file as CSS stylesheet
```javascript
loadjs(['css!/path/to/cssfile.custom'], function() {
/* cssfile.custom loaded as stylesheet */
});
```
1. Force treat file as image
```javascript
loadjs(['img!/path/to/image.custom'], function() {
/* image.custom loaded */
});
```
1. Add a bundle id
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', function() {
/* foo.js & bar.js loaded */
});
```
1. Use .ready() to define bundles and callbacks separately
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');
loadjs.ready('foobar', function() {
/* foo.js & bar.js loaded */
});
```
1. Use multiple bundles in .ready() dependency lists
```javascript
loadjs('/path/to/foo.js', 'foo');
loadjs(['/path/to/bar1.js', '/path/to/bar2.js'], 'bar');
loadjs.ready(['foo', 'bar'], function() {
/* foo.js & bar1.js & bar2.js loaded */
});
```
1. Chain .ready() together
```javascript
loadjs('/path/to/foo.js', 'foo');
loadjs('/path/to/bar.js', 'bar');
loadjs
.ready('foo', function() {
/* foo.js loaded */
})
.ready('bar', function() {
/* bar.js loaded */
});
```
1. Use Promises to register callbacks
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], {returnPromise: true})
.then(function() { /* foo.js & bar.js loaded */ })
.catch(function(pathsNotFound) { /* at least one didn't load */ });
```
1. Check if bundle has already been defined
```javascript
if (!loadjs.isDefined('foobar')) {
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', function() {
/* foo.js & bar.js loaded */
});
}
```
1. Fetch files in parallel and load them in series
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], {
success: function() { /* foo.js and bar.js loaded in series */ },
async: false
});
```
1. Add an error callback
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', {
success: function() { /* foo.js & bar.js loaded */ },
error: function(pathsNotFound) { /* at least one path didn't load */ }
});
```
1. Retry files before calling the error callback
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', {
success: function() { /* foo.js & bar.js loaded */ },
error: function(pathsNotFound) { /* at least one path didn't load */ },
numRetries: 3
});
// NOTE: Using `numRetries` with `async: false` can cause files to load out-of-sync on retries
```
1. Execute a callback before script tags are embedded
```javascript
loadjs(['/path/to/foo.js', '/path/to/bar.js'], {
success: function() {},
error: function(pathsNotFound) {},
before: function(path, scriptEl) {
/* called for each script node before being embedded */
if (path === '/path/to/foo.js') scriptEl.crossOrigin = true;
}
});
```
1. Bypass LoadJS default DOM insertion mechanism (DOM `<head>`)
```javascript
loadjs(['/path/to/foo.js'], {
success: function() {},
error: function(pathsNotFound) {},
before: function(path, scriptEl) {
document.body.appendChild(scriptEl);
/* return `false` to bypass default DOM insertion mechanism */
return false;
}
});
```
1. Use bundle ids in error callback
```javascript
loadjs('/path/to/foo.js', 'foo');
loadjs('/path/to/bar.js', 'bar');
loadjs(['/path/to/thunkor.js', '/path/to/thunky.js'], 'thunk');
// wait for multiple depdendencies
loadjs.ready(['foo', 'bar', 'thunk'], {
success: function() {
// foo.js & bar.js & thunkor.js & thunky.js loaded
},
error: function(depsNotFound) {
if (depsNotFound.indexOf('foo') > -1) {}; // foo failed
if (depsNotFound.indexOf('bar') > -1) {}; // bar failed
if (depsNotFound.indexOf('thunk') > -1) {}; // thunk failed
}
});
```
1. Use .done() for more control
```javascript
loadjs.ready(['dependency1', 'dependency2'], function() {
/* run code after dependencies have been met */
});
function fn1() {
loadjs.done('dependency1');
}
function fn2() {
loadjs.done('dependency2');
}
```
1. Reset dependency trackers
```javascript
loadjs.reset();
```
1. Implement a require-like dependency manager
```javascript
var bundles = {
'bundleA': ['/file1.js', '/file2.js'],
'bundleB': ['/file3.js', '/file4.js']
};
function require(bundleIds, callbackFn) {
bundleIds.forEach(function(bundleId) {
if (!loadjs.isDefined(bundleId)) loadjs(bundles[bundleId], bundleId);
});
loadjs.ready(bundleIds, callbackFn);
}
require(['bundleA'], function() { /* bundleA loaded */ });
require(['bundleB'], function() { /* bundleB loaded */ });
require(['bundleA', 'bundleB'], function() { /* bundleA and bundleB loaded */ });
```

## Development Quickstart
1. Install dependencies
* [nodejs](http://nodejs.org/)
* [npm](https://www.npmjs.org/)
* http-server (via npm)
1. Clone repository
```bash
$ git clone [email protected]:muicss/loadjs.git
$ cd loadjs
```
1. Install node dependencies using npm
```bash
$ npm install
```
1. Build examples
```bash
$ npm run build-examples
```
To view the examples you can use any static file server. To use the `nodejs` http-server module:
```bash
$ npm install http-server
$ npm run http-server -- -p 3000
```
Then visit [http://localhost:3000/examples](http://localhost:3000/examples)
1. Build distribution files
```bash
$ npm run build-dist
```
The files will be located in the `dist` directory.
1. Run tests
To run the browser tests first build the `loadjs` library:
```bash
$ npm run build-tests
```
Then visit [http://localhost:3000/test](http://localhost:3000/test)
1. Build all files
```bash
$ npm run build-all
```

LoadJS is based on the excellent <a href="https://github.com/ded/script.js">$script</a> library by <a href="https://github.com/ded">Dustin Diaz</a>. We kept the behavior of the library the same but we re-wrote the code from scratch to add support for error callbacks and to optimize the library for modern browsers. Currently, LoadJS is 590 bytes (minified + gzipped).
+The latest version of LoadJS can be found in the `dist/` directory in this repository:

'browserify\n==========\n\nMake node-style require() work in the browser with a server-side build step,\nas if by magic!\n\n[](http://travis-ci.org/substack/node-browserify)\n\n\n\nexample\n=======\n\nJust write an `entry.js` to start with some `require()`s in it:\n\n````javascript\n// use relative requires\nvar foo = require(\'./foo\');\nvar bar = require(\'../lib/bar\');\n\n// or use modules installed by npm into node_modules/\nvar gamma = require(\'gamma\');\n\nvar elem = document.getElementById(\'result\');\nvar x = foo(100) + bar(\'baz\');\nelem.textContent = gamma(x);\n````\n\nNow just use the `browserify` command to build a bundle starting at `entry.js`:\n\n```\n$ browserify entry.js -o bundle.js\n```\n\nAll of the modules that `entry.js` needs are included in the final bundle from a\nrecursive walk using [detective](https://github.com/substack/node-detective).\n\nTo use the bundle, just toss a `<script src="bundle.js"></script>` into your\nhtml!\n\nusage\n=====\n\n````\nUsage: browserify [entry files] {OPTIONS}\n\nOptions:\n --outfile, -o Write the browserify bundle to this file.\n If unspecified, browserify prints to stdout. \n --require, -r A module name or file to bundle.require()\n Optionally use a colon separator to set the target. \n --entry, -e An entry point of your app \n --exports Export these core objects, comma-separated list\n with any of: require, process. If unspecified, the\n export behavior will be inferred.\n \n --ignore, -i Ignore a file \n --alias, -a Register an alias with a colon separator: "to:from"\n Example: --alias \'jquery:jquery-browserify\' \n --cache, -c Turn on caching at $HOME/.config/browserling/cache.json or use\n a file for caching.\n [default: true]\n --debug, -d Switch on debugging mode with //@ sourceURL=...s. [boolean]\n --plugin, -p Use a plugin.\n Example: --plugin aliasify \n --prelude Include the code that defines require() in this bundle.\n [boolean] [default: true]\n --watch, -w Watch for changes. The script will stay open and write updates\n to the output every time any of the bundled files change.\n This option only works in tandem with -o. \n --verbose, -v Write out how many bytes were written in -o mode. This is\n especially useful with --watch. \n --help, -h Show this message \n\n````\n\ncompatibility\n=============\n\nMany [npm](http://npmjs.org) modules that don\'t do IO will just work after being\nbrowserified. Others take more work.\n\n[coffee script](http://coffeescript.org/) should pretty much just work.\nJust do `browserify entry.coffee` or `require(\'./foo.coffee\')`.\n\nMany node built-in modules have been wrapped to work in the browser.\nAll you need to do is `require()` them like in node.\n\n* events\n* path\n* [vm](https://github.com/substack/vm-browserify)\n* [http](https://github.com/substack/http-browserify)\n* [crypto](https://github.com/dominictarr/crypto-browserify)\n* assert\n* url\n* buffer\n* buffer_ieee754\n* util\n* querystring\n* stream\n\nprocess\n-------\n\nBrowserify makes available a faux `process` object to modules with these\nattributes:\n\n* nextTick(fn) - uses [the postMessage trick](http://dbaron.org/log/20100309-faster-timeouts)\n for a faster `setTimeout(fn, 0)` if it can\n* title - set to \'browser\' for browser code, \'node\' in regular node code\n* browser - `true`, good for testing if you\'re in a browser or in node\n\nBy default the process object is only available inside of files wrapped by\nbrowserify. To expose it, use `--exports=process`\n\n__dirname\n---------\n\nThe faux directory name, scrubbed of true directory information so as not to\nexpose your filesystem organization.\n\n__filename\n----------\n\nThe faux file path, scrubbed of true path information so as not to expose your\nfilesystem organization.\n\npackage.json\n============\n\nIn order to resolve main files for projects, the package.json "main" field is\nread.\n\nIf a package.json has a "browserify" field, you can override the standard "main"\nbehavior with something special just for browsers.\n\nSee [dnode\'s\npackage.json](https://github.com/substack/dnode/blob/9e24b97cf2ce931fbf6d7beb3731086b46bca887/package.json#L40)\nfor an example of using the "browserify" field.\n\nmore\n====\n\n* [browserify recipes](https://github.com/substack/node-browserify/blob/master/doc/recipes.markdown#recipes)\n* [browserify api reference](https://github.com/substack/node-browserify/blob/master/doc/methods.markdown#methods)\n* [browserify cdn](http://browserify.nodejitsu.com/)\n\ninstall\n=======\n\nWith [npm](http://npmjs.org) do:\n\n```\nnpm install -g browserify\n```\n\ntest\n====\n\nTo run the node tests with tap, do:\n\n```\nnpm test\n```\n\nTo run the [testling](http://testling.com)

> Making Laravel Passport work with Lumen
## Introduction
It's a simple service provider that makes **Laravel Passport** work with **Lumen**.
## Installation
First install [Lumen Micro-Framework](https://github.com/laravel/lumen) if you don't have it yet.
Then install **Lumen Passport**:
```bash
composer require dusterio/lumen-passport
```
Or if you prefer, edit `composer.json` manually and run then `composer update`:
```json
{
"require": {
"dusterio/lumen-passport": "^0.3.5"
}
}
```
### Modify the bootstrap flow
We need to enable both **Laravel Passport** provider and **Lumen Passport** specific provider:
```php
/** @file bootstrap/app.php */
// Enable Facades
$app->withFacades();
// Enable Eloquent
$app->withEloquent();
// Enable auth middleware (shipped with Lumen)
$app->routeMiddleware([
'auth' => App\Http\Middleware\Authenticate::class,
]);
// Register two service providers, Laravel Passport and Lumen adapter
$app->register(Laravel\Passport\PassportServiceProvider::class);
$app->register(Dusterio\LumenPassport\PassportServiceProvider::class);
```
### Laravel Passport ^7.3.2 and newer
On 30 Jul 2019 [Laravel Passport 7.3.2](https://github.com/laravel/passport/releases/tag/v7.3.2) had a breaking change - new method introduced on Application class that exists in Laravel but not in Lumen. You could either lock in to an older version or swap the Application class like follows:
```php
/** @file bootstrap/app.php */
//$app = new Laravel\Lumen\Application(
// dirname(__DIR__)
//);
$app = new \Dusterio\LumenPassport\Lumen7Application(
dirname(__DIR__)
);
```
\* _Note: If you look inside this class - all it does is adding an extra method `configurationIsCached()` that always returns `false`._
### Migrate and install Laravel Passport
```bash
# Create new tables for Passport
php artisan migrate
# Install encryption keys and other stuff for Passport
php artisan passport:install
```
It will output the Personal access client ID and secret, and the Password grand client ID and secret.
\* _Note: Save the secrets in a safe place, you'll need them later to request the access tokens._
## Configuration
### Configure Authentication
Edit `config/auth.php` to suit your needs. A simple example:
```php
/** @file config/auth.php */
return [
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => \App\Models\User::class
]
],
];
```
\* _Note: Lumen 7.x and older uses `\App\User::class`_
Load the config since Lumen doesn't load config files automatically:
```php
/** @file bootstrap/app.php */
$app->configure('auth');
];
```
## User model
Make sure your user model uses Passport's ```HasApiTokens``` trait, eg.:
```
### User model
Make sure your user model uses **Laravel Passport**'s `HasApiTokens` trait.
```php
/** @file app/Models/User.php */
use Laravel\Passport\HasApiTokens;
class User extends Model implements AuthenticatableContract, AuthorizableContract
{
use HasApiTokens, Authenticatable, Authorizable, HasFactory;
/* rest of the model */
}
```
## Usage
You'll find all the documentation in [Laravel Passport Docs](https://laravel.com/docs/master/passport).
### Curl example with username and password authentication
First you have to [issue an access token](https://laravel.com/docs/master/passport#issuing-access-tokens) and then you can use it to authenticate your requests.
```bash
# Request
curl --location --request POST '{{APP_URL}}/oauth/token' \
--header 'Content-Type: application/json' \
--data-raw '{
"grant_type": "password",
"client_id": "{{CLIENT_ID}}",
"client_secret": "{{CLIENT_SECRET}}",
"username": "{{USER_EMAIL}}",
"password": "{{USER_PASSWORD}}",
"scope": "*"
}'
```
```json
{
"token_type": "Bearer",
"expires_in": 31536000,
"access_token": "******",
"refresh_token": "******"
}
```
And with the `access_token` you can request access to the routes that uses the Auth:Api Middleware provided by the **Lumen Passport**.
```php
/** @file routes/web.php */
$router->get('/ping', ['middleware' => 'auth', fn () => 'pong']);
```
```bash
# Request
curl --location --request GET '{{APP_URL}}/ping' \
--header 'Authorization: Bearer {{ACCESS_TOKEN}}'
```
```html
pong
```
### Installed routes
This package mounts the following routes after you call `routes()` method, all of them belongs to the namespace `\Laravel\Passport\Http\Controllers`:
Verb | Path | Controller | Action | Middleware
--- | --- | --- | --- | ---
POST | /oauth/token | AccessTokenController | issueToken | -
GET | /oauth/tokens | AuthorizedAccessTokenController | forUser | auth
DELETE | /oauth/tokens/{token_id} | AuthorizedAccessTokenController | destroy | auth
POST | /oauth/token/refresh | TransientTokenController | refresh | auth
GET | /oauth/clients | ClientController | forUser | auth
POST | /oauth/clients | ClientController | store | auth
PUT | /oauth/clients/{client_id} | ClientController | update | auth
DELETE | /oauth/clients/{client_id} | ClientController | destroy | auth
GET | /oauth/scopes | ScopeController | all | auth
GET | /oauth/personal-access-tokens | PersonalAccessTokenController | forUser | auth
POST | /oauth/personal-access-tokens | PersonalAccessTokenController | store | auth
DELETE | /oauth/personal-access-tokens/{token_id} | PersonalAccessTokenController | destroy | auth
\* _Note: some of the **Laravel Passport**'s routes had to 'go away' because they are web-related and rely on sessions (eg. authorise pages). Lumen is an API framework so only API-related routes are present._
## Extra features
There are a couple of extra features that aren't present in **Laravel Passport**
### Prefixing Routes
You can add that into an existing group, or add use this route registrar independently like so;
```php
/** @file app/Providers/AuthServiceProvider.php */
use Dusterio\LumenPassport\LumenPassport;
class AuthServiceProvider extends ServiceProvider
{
public function boot()
{
LumenPassport::routes($this->app, ['prefix' => 'v1/oauth']);
/* rest of boot */
}
}
```
### Multiple tokens per client
Sometimes it's handy to allow multiple access tokens per password grant client. Eg. user logs in from several browsers
simultaneously. Currently **Laravel Passport** does not allow that.
```php
/** @file app/Providers/AuthServiceProvider.php */
use Dusterio\LumenPassport\LumenPassport;
class AuthServiceProvider extends ServiceProvider
{
public function boot()
{
LumenPassport::routes($this->app);
LumenPassport::allowMultipleTokens();
/* rest of boot */
}
}
```
### Different TTLs for different password clients
**Laravel Passport** allows to set one global TTL (time to live) for access tokens, but it may be useful sometimes to set different TTLs for different clients (eg. mobile users get more time than desktop users).
Simply do the following in your service provider:
```php
/** @file app/Providers/AuthServiceProvider.php */
use Carbon\Carbon;
use Dusterio\LumenPassport\LumenPassport;
class AuthServiceProvider extends ServiceProvider
{
public function boot()
{
LumenPassport::routes($this->app);
$client_id = '1';
LumenPassport::tokensExpireIn(Carbon::now()->addDays(14), $client_id);
/* rest of boot */
}
}
```
If you don't specify client Id, it will simply fall back to Laravel Passport implementation.
### Purge expired tokens
```bash
php artisan passport:purge
```
Simply run it to remove expired refresh tokens and their corresponding access tokens from the database.
## Error and issue resolution
Instead of opening a new issue, please see if someone has already had it and it has been resolved.
If you have found a bug or want to contribute to improving the package, please review the [Contributing guide](https://github.com/dusterio/lumen-passport/blob/master/CONTRIBUTING.md) and the [Code of Conduct](https://github.com/dusterio/lumen-passport/blob/master/CODE_OF_CONDUCT.md).
## Video tutorials
I've just started a educational YouTube channel [config.sys](https://www.youtube.com/channel/UCIvUJ1iVRjJP_xL0CD7cMpg) that will cover top IT trends in software development and DevOps.
Also I'm happy to announce my newest tool – [GrammarCI](https://www.grammarci.com/), an automated (as a part of CI/CD process) spelling and grammar checks for your code so that your users don't see your typos :)

+## Registering Routes
+
+Next, you should call the LumenPassport::routes method within the boot method of your application. This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:
+
+```php
+Dusterio\LumenPassport\LumenPassport::routes($app);
