    • Laravel framework’s built-in lightweight templates can be used to create several types of layouts using the content seeding.
    • Laravel offers the MVC(model-view-controller) architecture to ensure the separation between the business layer and presentation layer.

    How to Build a Laravel App with Authentication?

    Today, in this article, we will discuss how we can develop a Laravel application with authentication, its pre-requisites, development process, etc. Laravel is known for web application development with several functionalities like authentication and authorization. Let’s begin with the development process of the laravel app with authentication.

    Laravel uses the Composer to manage the dependencies, so it is must for you to install the PHP and Composer on your system before starting with the Laravel app development. 

    Installation of Composer and Laravel

    Steps to install the Composer on your system
    • Run create-project command in your terminal. The full command is 
    composer create-project --prefer-dist laravel/laravel GOT

    As we have mentioned earlier, Laravel has built-in command-line Artisan tool, you just need to run the following command to launch the application:

    php artisan serve

    You can use the following commands from the Laravel application directory like:

    Console –  all Artisan commands.

    Http – all controllers, middleware, requests, and routes files.

    Providers – all application service providers.

    Events – all event classes.

    Exceptions – application exception handler and custom exception classes.

    Jobs – all jobs in a queue.

    Listeners – all handler classes for your events.

    Policies – authorization policy classes for your application.

    Laravel App

    Controller Set-Up

    After installing the required tools like composer and laravel on your system, the next essential step is to create a ListController, to accomplish this, you need to open the terminal and run the following command in the project root directory.

    php artisan make:Controller ListController

    To follow the next step, you need to configure and open the file app/Http/Controllers/ListController.php. By using the view(‘welcome’)->withCharacters($characters), it implies that it is passing an array($characters) to a view known with the name welcome.blade.php.

    <?php>
    class ListController extends Controller
    {
    public function show()
    {
    $characters = [
       'micheal snow' => 'kelvin emison',
       'john watson' => 'gelly himiliton'
       ];
    return view('welcome')->withCharacters($characters);
    }
    }

    Model Set-Up

    If you ever checked, then you will find the Laravel models are stored by default in the app root directory. In this Laravel app development, we will not create any additional model, as we just need the User model that ships the Laravel framework. So, you just need to run the command as follows to create the Laravel model:

    php artisan make:model <modelName>

    Routes Set-Up

    To set up the routes in the Laravel app development, open the routes/web.php and configure it by the following command:

    Route::get('/', 'ListController@show');

    Now, in this command, when the ‘/‘ route hits, it invokes the show method of the ListController and renders the returned value in the welcome view.

    Authentication Set Up

    Here, we will set up the Laravel authentication with Auth0. No doubt, we can do the Laravel app authentication using the built-in authentication, but due to the limited featured, we will build laravel app development using the Auth0. By having the Auth0 authentication in the Laravel app development, it offers features like an easy-to-use dashboard, two-factor authentication, passwordless login, etc.

    After creating the Auth0, you will be redirected to the dashboard and here you need to click on “Application”->”Create Application”->”Laravel App”->”Regular Web Application” and press create. 

    Now update these values like:

    Allowed callback URLs: https//localhost:8000/auth0/callback

    Logout URLs: http://localhost:8000

    After updating these values in the “Settings”, now install the Auth0 PHP plugin and Auth0 Laravel plugin by using the following command in the terminal:

    composer require auth0/login:"~5.0"

    Make changes in the config/app.php file

    'providers' => [
    Auth0\Login\LoginServiceProviders::class,
    ];
    'alisases' => [
    'Auth0' => Auth0\Login\Facade\Auth0::class,
    ];

    Open the file app/Providers/AppServiceProvider.php

    class AppServiceProvider extends ServiceProvider
    {
    public function register()
    {
    $this->app->bind(
      \Auth0\Login\Contract\Auth0UserRepository::class,
      \Auth0\Login\Repository\Auth0UserRepository::class,
      );
     }
    }

    Now, publish the plugin configuration, by running the command in the terminal, and publish the plugin – Auth0/Login/LoginServiceProvider

    php artisan vendor: publish

    As the Auth0 file is sensitive, so there is a need to add .env file. So, you need to add the following in the .env file.

    AUTH0_DOMAIN=tws.auth0.com
    AUTH0_CLIENT_ID=client-id
    AUTH0_CLIENT_SECRET=client-secret

    Auth0 Integration

    To integrate the Auth0 in a Laravel App, you need to add some command-line code in the routes/web.php file. Follow these authenticate codes to create the authentication routes. By creating these routes, it will handle the login,logout, and redirect to Auth0 during login.

    Route: :get( '/auth0/callback', '\Auth0\Login\Auth0Controller@callback' ) 
    Route: :get( '/login', 'Auth\Auth0IndexController@login' )
    Route: :get( '/logout', 'Auth\Auth0IndexController@logout' )

    Now, run this command in the terminal

    php artisan make:controller Auth/Auth0IndexController

    Now, add this code, in the file app/Http/Controllers/Auth/Auth0IndexController.php

    <?php
    
    namespace App\Http\Controllers\Auth;
    use App\Http\Controllers\Controller;
    
    class Auth0IndexController extends Controller
    {
    
    public function login()
    {
    $authorize_params = [
     ];
    return \App::make('auth0')->login(null, null, $authorize_params);
    }
    
    public function logout()
    {
    \Auth::logout();
    $enterLogoutURL = sprintf( 'enter URL here' );
    env('AUTH0_DOMAIN'),
    env('AUTH0_CLIENT_ID'),
    env('URL'));
    return \Redirect::intended($enterLogoutURL);
    }
    }

    So, this is all the essential steps that are required for the development of a Laravel app with the authentication.

    Final Thoughts

    By going through this article, I think you will get an idea, how easy it is to create a Laravel app with authentication.
