> 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 */
$app->configure('auth');
```
### Registering Routes
Next, you should call the `LumenPassport::routes` method within the `boot` method of your application (one of your service providers). This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:
```php
/** @file app/Providers/AuthServiceProvider.php */
use Dusterio\LumenPassport\LumenPassport;
class AuthServiceProvider extends ServiceProvider
{
public function boot()
{
LumenPassport::routes($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}}'
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
```

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.

+## Workaround for Lumen 5.6
+
+Lumen 5.6 has a problem resolving HashManager class out of the box - Lumen refuses to resolve 'app' dependency through the
+service container. A quick workaround is to add a binding like following in any service provider:
+
+```php
+ $this->app->singleton(\Illuminate\Hashing\HashManager::class, function ($app) {
+ return new \Illuminate\Hashing\HashManager($app);
+ });
+```

{{pkg.description}}
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 it
apple.render();
apple.el.outerHTML;
//=> <div class="apple">hello</div>
```
## Installation
```
$ npm install fruitmachine
```

# AvaloniaEdit
This project is a port of [AvalonEdit](https://github.com/icsharpcode/AvalonEdit), a WPF-based text editor for [Avalonia](https://github.com/AvaloniaUI/Avalonia).
AvaloniaEdit supports features like:
* Syntax highlighting using [TextMate](https://github.com/danipen/TextMateSharp) grammars and themes.
* Code folding.
* Code completion.
* Fully customizable and extensible.
* Line numeration.
* Display whitespaces EOLs and tabs.
* Line virtualization.
* Multi-caret edition.
* Intra-column adornments.
* Word wrapping.
* Scrolling below document.
* Hyperlinks.
and many,many more!
AvaloniaEdit currently consists of 2 packages
* [Avalonia.AvaloniaEdit](https://www.nuget.org/packages/Avalonia.AvaloniaEdit) well-known package that incudes text editor itself.
* [AvaloniaEdit.TextMate](https://www.nuget.org/packages/AvaloniaEdit.TextMate/) package that adds TextMate integration to the AvaloniaEdit.
### How to set up TextMate theme and syntax highlighting for my project?
First of all, if you want to use grammars supported by [TextMateSharp](https://github.com/danipen/TextMateSharp), should install the following packages:
//Initial setup of TextMate.
var _textMateInstallation = _textEditor.InstallTextMate(_registryOptions);
//Here we are getting the lanuage by the extension and right after that we are initializing grammar with this lanuage.
//And that's all 😀, you are ready to use AvaloniaEdit with syntax highlighting!
_textMateInstallation.SetGrammar(_registryOptions.GetScopeByLanguageId(_registryOptions.GetLanguageByExtension(".cs").Id));
```
//Here we initialize RegistryOptions with the theme we want to use.
var _registryOptions = new RegistryOptions(ThemeName.DarkPlus);
//Initial setup of TextMate.
var _textMateInstallation = _textEditor.InstallTextMate(_registryOptions);
//Here we are getting the language by the extension and right after that we are initializing grammar with this language.
//And that's all 😀, you are ready to use AvaloniaEdit with syntax highlighting!

This project is a port of [AvalonEdit](https://github.com/icsharpcode/AvalonEdit), a WPF-based text editor for [Avalonia](https://github.com/AvaloniaUI/Avalonia).
AvaloniaEdit supports features like:
* Syntax highlighting using [TextMate](https://github.com/danipen/TextMateSharp) grammars and themes.
* Code folding.
* Code completion.
* Fully customizable and extensible.
* Line numeration.
* Display whitespaces EOLs and tabs.
* Line virtualization.
* Multi-caret edition.
* Intra-column adornments.
* Word wrapping.
* Scrolling below document.
* Hyperlinks.
and many,many more!
AvaloniaEdit currently consists of 2 packages
* [Avalonia.AvaloniaEdit](https://www.nuget.org/packages/Avalonia.AvaloniaEdit) well-known package that incudes text editor itself.
* [AvaloniaEdit.TextMate](https://www.nuget.org/packages/AvaloniaEdit.TextMate/) package that adds TextMate integration to the AvaloniaEdit.
### How to set up TextMate theme and syntax highlighting for my project?
First of all, if you want to use grammars supported by [TextMateSharp](https://github.com/danipen/TextMateSharp), should install the following packages:
//Initial setup of TextMate.
var _textMateInstallation = _textEditor.InstallTextMate(_registryOptions);
//Here we are getting the lanuage by the extension and right after that we are initializing grammar with this lanuage.
//And that's all 😀, you are ready to use AvaloniaEdit with syntax highlighting!
_textMateInstallation.SetGrammar(_registryOptions.GetScopeByLanguageId(_registryOptions.GetLanguageByExtension(".cs").Id));
```
//Here we initialize RegistryOptions with the theme we want to use.
var _registryOptions = new RegistryOptions(ThemeName.DarkPlus);
//Initial setup of TextMate.
var _textMateInstallation = _textEditor.InstallTextMate(_registryOptions);
//Here we are getting the language by the extension and right after that we are initializing grammar with this language.
//And that's all 😀, you are ready to use AvaloniaEdit with syntax highlighting!
_textMateInstallation.SetGrammar(_registryOptions.GetScopeByLanguageId(_registryOptions.GetLanguageByExtension(".cs").Id));
```
