namespace AppHttpControllers;

use IlluminateHttpRequest;

class HomeController extends Controller
{
    public function index()
    {
        return view('welcome');
    }
}

Copy after login

The above code returns a view named welcome. We will create this view in the next step.

Step 4: View
Laravel uses the Blade template engine to create views. Open the myproject/resources/views directory and create a file named welcome.blade.php. In the file, add the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Welcome</title>
</head>
<body>
    <h1>Welcome to Laravel</h1>
</body>
</html>

Copy after login

Step 5: Run the application
At this point, we have completed a basic Laravel application. Open the terminal and run the following command in the project root directory to start the built-in development server:

php artisan serve

Copy after login

Visit http://localhost:8000, you will see a message with the title "Welcome to Laravel" page.
