Lumen Passport

Lumen porting of Laravel Passport. The idea come from https://github.com/dusterio/lumen-passport but try to make it transparent with original laravel passport

Dependencies

• PHP >= 8.0
• Lumen >= 11.0
• Laravel Passport >= 12.0

Installation

First of all let's install Lumen Framework if you haven't already.

composer create-project --prefer-dist laravel/lumen lumen-app && cd lumen-app

Then install Lumen Passport (it will fetch Laravel Passport along):

composer require nomadnt/lumen-passport

Configuration

Generate your APP_KEY and update .env with single command

sed -i "s|\(APP_KEY=\)\(.*\)|\1$(openssl rand -base64 24)|" .env

Configure your database connection (ie to use SQLite) This is how your .env file should looking after the changes

Copy the Lumen configuration folder to your project

cp -a vendor/laravel/lumen-framework/config config

Update guards and provider section of your config/auth.php to match Passport requirements

<?php

return [
    ...

    'guards' => [
        'api' => ['driver' => 'passport', 'provider' => 'users']
    ],

    ...

    'providers' => [
        'users' => ['driver' => 'eloquent', 'model' => \App\Models\User::class]
    ]

    ...
];

You need to change a little the bootstrap/app.php file doing the following:

<?php

...

// enable facades
$app->withFacades();

// enable eloquent
$app->withEloquent();

...

$app->configure('app');

// initialize auth configuration
$app->configure('auth');

...

// enable auth and throttle middleware
$app->routeMiddleware([
    'auth'     => App\Http\Middleware\Authenticate::class,
    'throttle' => Nomadnt\LumenPassport\Middleware\ThrottleRequests::class
]);

...

// register required service providers

// $app->register(App\Providers\AppServiceProvider::class);
$app->register(App\Providers\AuthServiceProvider::class);
$app->register(Nomadnt\LumenPassport\PassportServiceProvider::class);
// $app->register(App\Providers\EventServiceProvider::class);

...

Create database.sqlite

touch database/database.sqlite

Lauch the migrations

php artisan migrate

Install Laravel passport

# Install encryption keys and other necessary stuff for Passport
php artisan passport:install

The previous command should give back to you an output similar to this:

Encryption keys generated successfully.
Personal access client created successfully.
Client ID: 1
Client secret: BxSueZnqimNTE0r98a0Egysq0qnonwkWDUl0KmE5
Password grant client created successfully.
Client ID: 2
Client secret: VFWuiJXTJhjb46Y04llOQqSd3kP3goqDLvVIkcIu

User model

Make sure your user model uses Passport's HasApiTokens trait, eg.:

<?php

namespace App;

use Illuminate\Auth\Authenticatable;
use Laravel\Passport\HasApiTokens;
use Laravel\Lumen\Auth\Authorizable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use HasApiTokens, Authenticatable, Authorizable;

    // rest of the model
}

Access Token Events

Prune and/or Revoke tokens

If you want to revoke or purge tokens on event based you have to create related Listeners and register on your app/Http/Providers/EventServiceProvider.php istead of using deprecated properties Passport::$revokeOtherTokens = true; and Passport::$pruneRevokedTokens = true;

First you need to make sure that EventServiceProvider is registered on your bootstrap/app.php

<?php

...

// $app->register(App\Providers\AppServiceProvider::class);
$app->register(App\Providers\AuthServiceProvider::class);
$app->register(Nomadnt\LumenPassport\PassportServiceProvider::class);
$app->register(App\Providers\EventServiceProvider::class);

...

Then you need to listen for AccessTokenCreated event and register your required listeners

<?php

namespace App\Providers;

use Laravel\Lumen\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider{

    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'Laravel\Passport\Events\AccessTokenCreated' => [
            'App\Listeners\RevokeOtherTokens',
            'App\Listeners\PruneRevokedTokens',
        ]
    ];
}

Create the app/Listeners/RevokeOtherTokens.php file and put the following content

<?php

namespace App\Listeners;

use Laravel\Passport\Events\AccessTokenCreated;
use Laravel\Passport\Token;

class RevokeOtherTokens
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  \App\Events\OrderShipped  $event
     * @return void
     */
    public function handle(AccessTokenCreated $event)
    {
        Token::where(function($query) use($event){
            $query->where('user_id', $event->userId);
            $query->where('id', '<>', $event->tokenId);
        })->revoke();
    }
}

Create the app/Listeners/PruneRevokedTokens.php file and put the following content

<?php

namespace App\Listeners;

use Laravel\Passport\Events\AccessTokenCreated;
use Laravel\Passport\Token;

class PruneRevokedTokens
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  \App\Events\AccessTokenCreated  $event
     * @return void
     */
    public function handle(AccessTokenCreated $event)
    {
        Token::where(function($query) use($event){
            $query->where('user_id', $event->userId);
            $query->where('id', '<>', $event->tokenId);
            $query->where('revoked', true);
        })->delete();
    }
}
