Laravel frameworks store middleware in the app\http\middleware directory of the project. New middleware can be created using the following Artisan command:

php artisan make:middleware exampleMiddleware
Middleware creation in Laravel

The command above will create a new file with a .php extension in the app\http\middleware directory. After the successful execution of the command, the following file will be created:

<?php



namespace App\Http\Middleware;



use Closure;

use Illuminate\Http\Request;



class exampleMiddleware

{

    /**

     * Handle an incoming request.

     *

     * @param  \Illuminate\Http\Request  $request

     * @param  \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next

     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse

     */

    public function handle(Request $request, Closure $next)

    {

        return $next($request);

    }
