How to Create and Register Middleware in Laravel 11?

Middleware in Laravel acts as a bridge between request and response. Middleware are used for various purposes like authentication, logging, security and much more.

In this blog, we will learn the process of creating and registering middleware in Laravel 11.  

Steps to Create and Register Middleware in Laravel 11:

In Laravel 11, we show no kernel.php file and the Middleware directory is not present.

Here is the step-by-step guide for it.

Let’s take one example for it.

Step 1: Define/Create a Middleware

We can create a middleware by using this command 

$ php artisan make:middleware EnsureTokenIsValid

This command will create a new middleware EnsureTokenIsValid at the app/Http/Middleware directory.

Now replace this file with the following code. The code works like if the input token does not have the same value as my-secret-token; then it will redirect to the home page.

app/Http/Middleware/EnsureTokenIsValid.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class EnsureTokenIsValid
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        if ($request->input('token') !== 'my-secret-token') {
            return redirect('/home');
        }

        return $next($request);
    }
}

Step 2: Register alias for the middleware 

Now, we can register this middleware with proper alias. Open the bootstrap/app.php file and write the below code.

bootstrap/app.php
//....
->withMiddleware(function (Middleware $middleware) {
        $middleware->alias([
            "isValidToken" => App\Http\Middleware\EnsureTokenIsValid::class
        ]);
})
// other stuff do

Step 3: Use middleware

Now, we can use this middleware in web.php.

Use 1: 

use App\Http\Middleware\EnsureTokenIsValid;
 
Route::get('/profile', function () {
    // ...
})->middleware(EnsureTokenIsValid::class);

Use 2:

use App\Http\Middleware\EnsureTokenIsValid;
 
Route::get('/profile', function () {
    // ...
})->middleware('isValidToken');
