Create Middleware in Laravel 11 Application

Making or using middleware in laravel is a special need for sometimes. Middleware in laravel is a special class that is used for filtering http request before sending it to final output. In middleware we can filter request based on role, specific condition or something else. In Laravel 11 define middleware is so much easy with some steps. In this blog we will define middleware and try to see how it is used . 

Define middleware

php artisan make:middleware DemoMiddleware

DemoMiddleware

namespace App\Http\Middleware;

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

class DemoMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        if ($request->isMethod('POST')) { //you can write any logic here
            abort(403);
        }
        return $next($request);
    }
}

This DemoMiddleware will be located inside app/Http/Middleware directory

Let's add this middleware in our bootstrap/app.php file

//bootstrap/app.php

use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        api: __DIR__.'/../routes/api.php',
        commands: __DIR__.'/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->web(append: [
            \App\Http\Middleware\HandleInertiaRequests::class,
            \Illuminate\Http\Middleware\AddLinkHeadersForPreloadedAssets::class,
            \App\Http\Middleware\DemoMiddleware::class,
        ]);

        //
    })
    ->withExceptions(function (Exceptions $exceptions) {
        //
    })->create();

Use middleweare in route level

If we want to use our defined middleware in route level then we can use this in in route group or use for single route

Middleware use in route groups

//routes/web.phpp

Route::middleware([
    'auth:sanctum',
    config('jetstream.auth_session'),
    'verified',
    \App\Http\Middleware\DemoMiddleware::class,
])->group(function () {
    Route::get('/dashboard', function () {
        return Inertia::render('Dashboard');
    })->name('dashboard');
});

Middleware use for single route

//routes/web.phpp

Route::middleware([
    'auth:sanctum',
    config('jetstream.auth_session'),
    'verified',
])->group(function () {
    Route::get('profile',[UserProfileController::class,'show'])
		->middleware([\App\Http\Middleware\DemoMiddleware::class]);
});

You can use middleware based on your needs
