Laravel JWT - PHP

Laravel is a popular PHP framework for building web applications. JWT (JSON Web Tokens) are a way to authenticate users and provide secure communication between client and server. The tymon/jwt-auth package is a popular Laravel package that provides JWT authentication for your Laravel application.

Installing JWT Authentication in Laravel

To install JWT authentication in Laravel using the tymon/jwt-auth package:

1. Install the package using Composer:

composer require tymon/jwt-auth

2. Add the service provider to the providers array in the config/app.php file:

Tymon\JWTAuth\Providers\LaravelServiceProvider::class,

3. Publish the configuration files:

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

4. Generate the JWT secret:

php artisan jwt:secret

This will create a .env file with a JWT_SECRET key.

5. Configure your authentication guards to use JWT:

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

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

Using JWT Authentication in Laravel

To use JWT authentication in your Laravel application:

1. Generate a token:

use Tymon\JWTAuth\Facades\JWTAuth;

$token = JWTAuth::attempt($credentials);

2. Add the token to the response:

return response()->json(['token' => $token]);

3. Authenticate the user using the token:

use Tymon\JWTAuth\Facades\JWTAuth;

$user = JWTAuth::parseToken()->authenticate();

4. Protect routes with JWT authentication using middleware:

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});
