Knowing how to create and use controllers with Artisan is essential for Laravel developers to build scalable web applications.

1

Create the BookController using Artisan

Use the Artisan command php artisan make:controller BookController to create a new controller named BookController inside the app/Http/Controllers directory.

Laravel

# Run the Artisan command to create BookController
# Your code here

Need a hint?

Open your terminal and type exactly php artisan make:controller BookController to create the controller.

2

Add an index method to BookController

Open the BookController.php file and add a public method named index that returns a simple string 'List of books'.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class BookController extends Controller
{
    // Add a public function named index that returns 'List of books'
    # Your code here
}

Need a hint?

Inside the BookController class, write public function index() and return the string 'List of books'.

3

Add a show method with an ID parameter

Inside BookController, add a public method named show that accepts a parameter $id and returns the string 'Showing book with ID: ' . $id.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class BookController extends Controller
{
    public function index()
    {
        return 'List of books';
    }

    // Add a public function named show that accepts $id and returns 'Showing book with ID: ' . $id
    # Your code here
}

Need a hint?

Define public function show($id) and return the string concatenating 'Showing book with ID: ' and $id.

4

Register routes for the controller methods

Open the routes/web.php file and add two routes: one GET route for /books that uses BookController@index, and one GET route for /books/{id} that uses BookController@show.

Laravel

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\BookController;

// Add a GET route for '/books' that uses BookController@index
// Add a GET route for '/books/{id}' that uses BookController@show
# Your code here

Need a hint?

Use Route::get with the URL and controller method array syntax to register the routes.
