How To Create invokable Controller In Laravel

Hi Developers,

Lets see about the invokable controller, If any of the controller function is more complex it will be more convenient to dedicate the entire controller class to do a single action. This can be achieved by using the __invoke method in Laravel. By declaring the controller as a invokable controller it can be only use to do the specific functions only, Lets see how its done.

Creating the invokable Controller : Creating a invokable controller is similar as of creating normal controller. It is done by adding --invokable in the Artisan command.

php artisan make:controller ProvisionServer --invokable

While declaring the route for the invokable controller we don't have to determine the class name since invokable controller it dedicated to perform a single function only.

web.php

use App\Http\Controllers\ProvisionServer;
 
Route::get('/server', ProvisionServer::class);

Defining the invokable controller : The controller is declared by adding the __invoke()

<?php
 
namespace App\Http\Controllers;
 
class ProvisionServer extends Controller
{
    /**
     * Provision a new web server.
     */
    public function __invoke()
    {
        // ...
    }
}

Running the Laravel Project

php artisan serve

Calling the Controller via Route

http://localhost:8000/server
