How to Implement JWT Authentication in Laravel 12
- Laravel: A PHP framework for building web applications, following the MVC (Model-View-Controller) architecture. It provides built-in tools for authentication, routing, databases, and more.
- JWT (JSON Web Token): A secure way to transmit data between parties as a JSON object, commonly used for authentication. In Laravel, JWT is often used to create stateless authentication for APIs.
1.Installing the JWT-Auth Package
(install api : php artisan install:api)
Run the following command to install the JWT package:
composer require tymon/jwt-auth
After installation, publish the package configuration:
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
This will create a config/jwt.php file where you can customize the JWT settings.
2.Generate JWT Secret Key
Run the following command to generate a secret key:
php artisan jwt:secret
This key will be stored in your .env file:
JWT_SECRET=strong_secret_word
3. Configure the Authentication Guard
Modify the config/auth.php file and set the guard driver to jwt:
'guards' => [
'api' => [
'driver' => 'jwt',
'provider' => 'users',
],
],
4. Modify the User Model
In app/Models/User.php (or app/User.php in older versions), implement the JWTSubject interface:
use Tymon\JWTAuth\Contracts\JWTSubject;
class User extends Authenticatable implements JWTSubject
{
/**
* Get the identifier that will be stored in the JWT token.
*/
public function getJWTIdentifier()
{
return $this->getKey();
}
/**
* Return an array with custom claims to be added to the JWT token.
*/
public function getJWTCustomClaims()
{
return [];
}
}
5. Create Authentication Controller
Generate a new controller:
php artisan make:controller AuthController
Inside app/Http/Controllers/AuthController.php, implement the login, register, and logout functions:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Auth;
use Tymon\JWTAuth\Facades\JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
class AuthController extends Controller
{
public function register(Request $request)
{
$request->validate([
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
]);
$user = User::create([
'name' => $request->name,
'email' => $request->email,
'password' => Hash::make($request->password),
]);
try {
$token = JWTAuth::fromUser($user);
} catch (JWTException $e) {
return response()->json(['error' => 'Could not create token'], 500);
}
return response()->json([
'token' => $token,
'user' => $user,
], 201);
}
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
try {
if (!$token = JWTAuth::attempt($credentials)) {
return response()->json(['error' => 'Invalid credentials'], 401);
}
} catch (JWTException $e) {
return response()->json(['error' => 'Could not create token'], 500);
}
return response()->json([
'token' => $token
'expires_in' => auth('api')->factory()->getTTL() * 60,
]);
}
public function logout()
{
try {
JWTAuth::invalidate(JWTAuth::getToken());
} catch (JWTException $e) {
return response()->json(['error' => 'Failed to logout, please try again'], 500);
}
return response()->json(['message' => 'Successfully logged out']);
}
public function getUser()
{
try {
$user = Auth::user();
if (!$user) {
return response()->json(['error' => 'User not found'], 404);
}
return response()->json($user);
} catch (JWTException $e) {
return response()->json(['error' => 'Failed to fetch user profile'], 500);
}
}
public function updateUser(Request $request)
{
try {
$user = Auth::user();
$user->update($request->only(['name', 'email']));
return response()->json($user);
} catch (JWTException $e) {
return response()->json(['error' => 'Failed to update user'], 500);
}
}
}
6. Middleware
You can also create middleware to protect routes:
php artisan make:middleware JwtMiddleware
In app/Http/Middleware/JwtMiddleware.php, update the handle function:
namespace App\Http\Middleware;
use Closure;
use Tymon\JWTAuth\Facades\JWTAuth;
use Exception;
use Illuminate\Http\Request;
class JwtMiddleware
{
public function handle(Request $request, Closure $next)
{
try {
JWTAuth::parseToken()->authenticate();
} catch (Exception $e) {
return response()->json(['error' => 'Unauthorized'], 401);
}
return $next($request);
}
}
in Laravel 12, middleware registration has been moved to the bootstrap/app.php file.
->withMiddleware(function (Middleware $middleware) {
//
$middleware->alias([
'jwt' => JwtMiddleware::class
]);
})
7. Define API Routes
Open routes/api.php and add these routes:
<?php
use App\Http\Controllers\AuthController;
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return response()->json(['message' => 'Hello world!']);
});
Route::post('/register', [AuthController::class, 'register']);
Route::post('/login', [AuthController::class, 'login']);
Route::middleware('jwt')->group(function () {
Route::get('/user', [AuthController::class, 'getUser']);
Route::post('/logout', [AuthController::class, 'logout']);
Route::put('/user', [AuthController::class, 'updateUser']);
});
Define API Routes
se Postman or any API testing tool to test the following endpoints:
- POST
/register: Register a new user. - POST
/login: Log in and get a JWT token. - GET
/user: Fetch the authenticated user's details (requires JWT token). - POST
/logout: Invalidate the JWT token. - POST
/refresh: Refresh the JWT token.
