Create Custom JWT Token Laravel | Guide

Get ready to learn how to create a custom JSON Web Token (JWT) in a Laravel application.

JWTs help with authentication and authorization purposes. This lets us generate and validate tokens that represent user identity or other information.

Let’s take a quick look at how to create a custom JWT in Laravel:

1. To begin with, we have to install a JWT package like tymon/jwt-auth to make it easier to work with JWTs in Laravel.

   composer require tymon/jwt-auth
2. Then, we have to publish its configuration files:

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

   This will publish the configuration file config/jwt.php. We can customize JWT settings there.
3. Now, it is time to generate a custom JWT. We can create a custom method in our Laravel application.

   For example, here we are generating a token with custom claims (payload data):

   

   Here,

   • auth()->user() retrieves the user we want to associate with the token. We can replace this with our user retrieval logic.
   • $customClaims is an array of custom claims we want to include in the token. These claims can contain additional user information.
4. In order to protect routes and require a valid JWT for access, we need Laravel’s middleware. Furthermore, we can apply the auth:api middleware in our route definition or controller:

   Route::middleware(['auth:api'])->group(function () {
// Protected routes go here
});

   Routes in this group will require a valid JWT for access.
5. Once a request is made to a protected route with a JWT in the Authorization header, Laravel will automatically validate the token. We can access the authenticated user with auth()->user().

   For example:

   public function protectedRoute()
{
$user = auth()->user();
// Your logic for the protected route
}

This lets us create a custom JWT token, protect routes, and authenticate users in our Laravel application. Custom claims lets us include additional data in the JWT payload as needed.
