How do you make and use Middleware in Laravel?

It acts as a middleman between a request and a response. Middleware is a type of filtering mechanism used in Laravel application.

• We can create middleware with
  php artisan make:middleware UsersMiddleware
• Here "UsersMiddleware" is the name of Middleware. After this command, a "UsersMiddleware.php" file is created in app/Http/Middleware directory.
• After that we have to register that middleware in kernel.php (available in app/Http directory) file in "$routeMiddleware" variable.
  'Users' => \App\Http\Middleware\UsersMiddleware::class,
• Now we can call "Users" middleware where we need it like controller or route file.
• We can use it in a controller file like this.
  public function __construct() {
   $this->middleware('Users');
}
• In route file we can use like this.
  Route::group(['middleware' => 'Users'], function () {
   Route::get('/', 'HomeController@index');
});
