Laravel - Routing - Middleware

To assign middleware to all routes within a group, you may use the middleware method before defining the group. Middleware are executed in the order they are listed in the array:

Route::middleware(['first', 'second'])->group(function () {
    Route::get('/', function () {
        // Uses first & second middleware...
    });

    Route::get('/user/profile', function () {
        // Uses first & second middleware...
    });
});
