Laravel 6.0 is out! Check out Build a Laravel 6 CRUD App with Authentication to learn what new things Laravel can do for you.
This blog post covers Laravel 5.8.

TL;DR: Laravel is a great PHP framework. Currently, it is the most starred PHP project on Github and a lot of companies and people all over the world use it to build amazing applications. In this tutorial, I'll show you how easy it is to build a web application with Laravel and add authentication to it without breaking a sweat. Check out the repo to get the code.

Laravel is a free, open-source PHP framework designed for building web applications with an expressive and elegant syntax. Laravel has a high level of abstraction which shields the common developer from complex inner workings. Laravel saves you time and effort because it ships with a lot of features out of the box. These amazing features include:

  • Database Migrations
  • Eloquent ORM
  • Authorization and Policies
  • Scheduler
  • Queuing

Laravel makes good use of already written and well-tested components from the PHP community. It is one of the few frameworks that comes with development environments such as Homestead and Valet. The documentation is very detailed and there is a large community based around Laravel. Some of the notable communities are,,, and

We'll be building a simple character listing app with Laravel 5.8. Our app will simply list 10 Game of Thrones characters and their real names. Once we add authentication to the app, all logged-in users will have the privilege of knowing these celebrity characters personally.

Let's Get Started

Laravel utilizes Composer to manage its dependencies. So, before using Laravel, make sure you have Composer installed on your machine. We can install Laravel by issuing the Composer create-project command in your terminal like so: composer create-project --prefer-dist laravel/laravel GOT or using the laravel installer.

It's faster to spin up a new app using the laravel command like so: laravel new GOT. Check out the Laravel docs to learn how to set up the Laravel installer.

If you used the laravel installer command to create a new app, then you have to run composer install immediately after the previous command to install all the dependencies.

Now run the following in your terminal to launch your application:

php artisan serve

Explore Directory Structure

Laravel applications follow the Model-View-Controller design pattern.

In a nutshell,

  • Models query your database and return the necessary data.
  • Views are pages that render data
  • Controllers handle user requests, retrieve data from the models, and pass them to the views.

Read more about MVC here.

The app directory is the meat of your Laravel application. It houses the following directories:

  • Console
    • Contains all your Artisan commands
  • Http
    • Contains all your controllers, middleware, requests, and routes file
  • Providers
    • Contains all your application service providers. You can read more about Service Providers here
  • Events
    • Contains all your event classes
  • Exceptions
    • Contains your application exception handler and custom exception classes
  • Jobs
    • Contains all the jobs queued by your application
  • Listeners
    • Contains all the handler classes for your events
  • Policies
    • Contains the authorization policy classes for your application. Policies are used to determine if a user can perform a given action against a resource.

The other directories namely:

  • boostrap contains your framework autoloading files and generated cache files
  • config contains your app's configuration files
  • database contains your database migrations and seeds
  • public contains your assets (images, JavaScript, css, etc.)
  • resources contains your views and localization files
  • storage contains all your compiled Blade templates, file caches, and logs
  • tests contains all your tests
  • vendor contains your app dependencies

Setting Up The Controller

Open up your terminal and in the project root directory, run the command below to create a ListController.

php artisan make:controller ListController

Open up app/Http/Controllers/ListController.php and configure it like so:


namespace App\Http\Controllers;

class ListController extends Controller
    public function show()
       $characters = [
         'Daenerys Targaryen' => 'Emilia Clarke',
         'Jon Snow'           => 'Kit Harington',
         'Arya Stark'         => 'Maisie Williams',
         'Melisandre'         => 'Carice van Houten',
         'Khal Drogo'         => 'Jason Momoa',
         'Tyrion Lannister'   => 'Peter Dinklage',
         'Ramsay Bolton'      => 'Iwan Rheon',
         'Petyr Baelish'      => 'Aidan Gillen',
         'Brienne of Tarth'   => 'Gwendoline Christie',
         'Lord Varys'         => 'Conleth Hill'

       return view('welcome')->withCharacters($characters);

view('welcome')->withCharacters($characters) indicates that we are passing the $characters array to a view called welcome.blade.php. We'll create that view later in this post.

Setting Up The Model

Laravel models are stored by default in the root of the app directory. The User model ships with the Laravel framework. Only the User model is needed in this application so we won't create any additional models. However, if you want to create more models, you can simply run the command below like so:

php artisan make:model <modelName>

where <modelName> represents the name of the model you want to create.

Setting Up The Routes

Open up routes/web.php and configure it like so:

| Application Routes
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.

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

Once a request hits the / route, it invokes the show method of the ListController and renders the returned value in the welcome view. We'll configure the welcome view later in this post.

Setting Up Authentication

We're going to be using Auth0 for authentication. Setting up the built-in authentication with Laravel is pretty straightforward, but limited. With Auth0, you'll have access to an easy-to-use dashboard, the ability to integrate social identity providers, two-factor authentication, passwordless login, and more. And luckily, it's just as easy to integrate with your Laravel application! Let's check it out.

If you don't already have an account, go ahead and sign up for a free Auth0 account here.

After you've signed up, head to the dashboard and click on "Applications". Click on "Create Application" and name the application "Laravel App" or anything you'd like. Then click on "Regular Web Application" and press create.

Next, you need to add the valid callback URLs and logout URLs in the dashboard.

Click on "Applications" and select the application you just created (or the default one). Next, click on "Settings".

Update these values as follows:

  • Allowed callback URLs: http://localhost:8000/auth0/callback
  • Logout URLs: http://localhost:8000

Next, go back to your terminal and install the Auth0 PHP plugin and Auth0 Laravel plugin:

composer require auth0/login:"~5.0"

Now open the config/app.php file and add the Auth0 login service provider to the list of providers:

// ...
'providers' => [
    // ...

Then scroll down to the aliases array and add the Auth0 facade:

// ...
'aliases' => [
    // ...
    'Auth0' => Auth0\Login\Facade\Auth0::class,

Next, open app/Providers/AppServiceProvider.php and add the following under register():

// ...
class AppServiceProvider extends ServiceProvider
  // ...
  public function register()

You need to publish the plugin configuration. In your terminal, run:

php artisan vendor:publish

When it asks which file you'd like to publish, select Auth0\Login\LoginServiceProvider.

This will create the config/laravel-auth0.php file. Open this up now and you'll see it's using some Auth0 variables. These are sensitive, so you need to add them to the .env file.

Open up .env and add:

To fill in these values, head back to your Auth0 dashboard, select your application, and click on "Settings".

While you have .env open, double-check that APP_URL matches your dev URL exactly, including the port. It should say APP_URL=http://localhost:8000. If not, update that now.

The last configuration step is to switch out the Laravel user driver to use Auth0.

Open up config/auth.php, scroll down to providers, and paste in:

'providers' => [
  'users' => [
    'driver' => 'auth0',

Now that you have the Auth0 plugin configured, you just need to integrate it into the application.

Integrating Auth0

Open up routes/web.php and add these authentication routes:

Route::get( '/auth0/callback', '\Auth0\Login\Auth0Controller@callback' )->name( 'auth0-callback' );
Route::get( '/login', 'Auth\Auth0IndexController@login' )->name( 'login' );
Route::get( '/logout', 'Auth\Auth0IndexController@logout' )->name( 'logout' )->middleware('auth');

These routes will handle the login, logout, and redirect to Auth0 during login. Now you need to create that Auth0IndexController.

In your terminal, run:

php artisan make:controller Auth/Auth0IndexController

Open up app/Http/Controllers/Auth/Auth0IndexController.php and replace it with:


namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class Auth0IndexController extends Controller
    * Redirect to the Auth0 hosted login page
    * @return mixed
  public function login()
    $authorize_params = [
      'scope' => 'openid profile email',
    return \App::make('auth0')->login(null, null, $authorize_params);

    * Log out of Auth0
    * @return mixed
  public function logout()
    $logoutUrl = sprintf(
    return  \Redirect::intended($logoutUrl);

The scopes being requested in the login() function are: openid, profile, and email.

There is also a logout() function that will clear all session data to log the user out.

Now it's time to wire up the buttons so that users can sign in and out.

Open up your welcome.blade.php and configure it like so:

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
      <meta charset="utf-8">
      <meta name="viewport" content="width=device-width, initial-scale=1">
    <div class="flex-center position-ref full-height">
      @if (Route::has('login'))
      <div class="top-right links">
          <a href="{{ url('/home') }}">Home</a>
          <a href="{{ url('/logout') }}">Logout</a>
          <a href="{{ route('login') }}">Login</a>
      <div class="container">
        <div class="row">
          <div class="col-md-10 col-md-offset-1">
            <div class="panel panel-success">
              <div class="panel-heading">List of Game of Thrones Characters</div>
              <!-- Table -->
              <table class="table">
                  <th>Real Name</th>
                @foreach($characters as $key => $value)
                  <td>{{ $key }}</td><td>{{ $value }}</td>
            <a href="/login" class="btn btn-info"> You need to login to see the list 😜😜 >></a>

Here, we are looping through the $characters array data passed from the ListController for appropriate rendering in the welcome view.

Auth::user() - You can check if a user is authenticated or not via this method from the Auth Facade. It returns true if a user is logged-in and false if a user is not. Check here for more about how Facades work in Laravel.

Auth::guest() - This does the opposite of Auth::user(). It returns true if a user is not logged in and false if a user is logged in. Check here to see all the methods you can call on the Auth Facade.

Now that we have all the routes and views setup, your application should look like this:

Landing Page

Laravel application localhost home page

If you were to implement authentication on your own, you might have a login and register page like this:

Login Page

Laravel login page

Register Page

Laravel register page

Because we're using Auth0 for authentication, our application will redirect users to the Auth0 login page, so you don't have to create these on your own!

Using the Auth Middleware

Middlewares provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen. However, if the user is authenticated, the middleware will allow the request to proceed further. The app/Http/Middleware directory contains several middleware.

Let's check out how the auth middleware works.

Add a new route to your routes/web.php file like so:

Route::get('/got', [
  'middleware' => ['auth'],
  'uses' => function () {
    echo "You are allowed to view this page!";

If you're still logged in, head to http://localhost:8000/got and you should get the message "You are allowed to view this page!". Now, log out, then try to access that route and you will be redirected back to Auth0 to sign in.

The Laravel auth middleware intercepted the request, checked if the user was logged-in, discovered that the user was not logged-in, then redirected the user back to the login route, which sent them to Auth0.

Wrapping Up

Well done! You have just built your first app with Laravel. Laravel is an awesome framework to work with. It focuses on simplicity, clarity and getting work done. As we saw in this tutorial, you can easily activate the built-in authentication to your Laravel applications. If you find yourself needing more, you can also integrate Auth0 just as easily.
