> 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"
}
}
```json
{
"require": {
"dusterio/lumen-passport": "~0.1"
}
}
```
/** @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 */
$app->configure('auth');
```
### Registering Routes
Next, you should call the `LumenPassport::routes` method within the `boot` method of your application (one of your service providers). This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:
```php
/** @file app/Providers/AuthServiceProvider.php */
use Dusterio\LumenPassport\LumenPassport;
class AuthServiceProvider extends ServiceProvider
{
public function boot()
{
LumenPassport::routes($this->app);
/* rest of boot */
}
}
```
### 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 :)

<img src="https://www.muicss.com/static/images/loadjs.svg" width="250px">
LoadJS is a tiny async loader for modern browsers (590 bytes).
[](https://travis-ci.org/muicss/loadjs)
[](https://david-dm.org/muicss/loadjs)
[](https://david-dm.org/muicss/loadjs#info=devDependencies)
## 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 [$script](https://github.com/ded/script.js) library by [Dustin Diaz](https://github.com/ded). We kept the behavior of the library the same but we re-wrote the code from scratch to add support for success/error callbacks and to optimize the library for modern browsers. LoadJS is 899 bytes (minified + gzipped).
Here's an example of what you can do with LoadJS:
```html
<script src="//unpkg.com/loadjs@latest/dist/loadjs.min.js"></script>
<script>
// define a dependency bundle and execute code when it loads
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');
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() {
});
```
## Development Dependencies
* nodejs (http://nodejs.org/)
* npm (https://www.npmjs.org/)
## Directory structure
<pre>
```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 */
| └── loadjs.js
├── test/
</pre>
})
.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 */ });
```

LoadJS is a tiny async loader for modern browsers (590 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 [$script](https://github.com/ded/script.js) library by [Dustin Diaz](https://github.com/ded). We kept the behavior of the library the same but we re-wrote the code from scratch to add support for success/error callbacks and to optimize the library for modern browsers. LoadJS is 899 bytes (minified + gzipped).
Here's an example of what you can do with LoadJS:
```html
<script src="//unpkg.com/loadjs@latest/dist/loadjs.min.js"></script>
<script>
// define a dependency bundle and execute code when it loads
loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');
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() {
});
```
## Development Dependencies
* nodejs (http://nodejs.org/)
* npm (https://www.npmjs.org/)

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
}
});
```

function fn1() {
loadjs.done('dependency1');

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 */ });

<BEF> # FruitMachine [](https://travis-ci.com/ftlabs/fruitmachine) [](https://coveralls.io/r/ftlabs/fruitmachine)
A lightweight component layout engine for client and server.
FruitMachine is designed to build rich interactive layouts from modular, reusable components. It's light and unopinionated so that it can be applied to almost any layout problem. FruitMachine is currently powering the [FT Web App](http://apps.ft.com/ftwebapp/).
```js
// Define a module
var Apple = fruitmachine.define({
name: 'apple',
template: function(){ return 'hello' }
});
// Create a module
var apple = new Apple();
// Render & inject into DOM
apple.render().inject(document.body);
apple.el.outerHTML;
//=> <div class="apple">hello</div>
## Installation
