Today, we will discuss how to build a Laravel App with Authentication, but before doing so, let’s first learn about the framework and its features in detail. Let’s begin!

Laravel is a free, open-source PHP-based backend framework used for the development of web applications. Talking about the popularity of the Laravel Framework on the Similartech Website, Around 130, 266 Websites are developed using the Laravel Framework.

Laravel – A PHP framework that has an immense number of features that are beneficial for web application development. Let’s have a look at the Laravel features why should you choose the Laravel framework for web applications development.

• 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.
• The feature of Eloquent ORM (Object Relational Mapping) facilitates the developers to write the database queries using PHP queries instead of the SQL code.
• Laravel framework provides an impressive level of security as it uses the prepared SQL statements that prevent SQL injection attacks.
• Laravel framework helps to automate the tedious repetitive programming tasks due to the presence of the built-in command-line tools named Artisans.
• Laravel allows the developers to perform multiple unit tests that avoid unexpected web application breakage.
• Laravel framework’s amazing database migration system helps to expand the web application database without re-creating whenever there is any change in the code.
• Laravel framework is the collection of object-oriented and modular libraries used to Create fantastic web applications.

Thus, the Laravel framework has a high level of abstraction that helps the developers from the complex inner workings. Due to the presence of the out of the box features, it saves the developer’s time and efforts as well. More interestingly, Laravel is one of the best frameworks that have development environments like Homestead and Valet.

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

• Run the 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 a 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:

• 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.

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>

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.

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 features, 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 a .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

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