Download the PHP package faithfm/laravel-simple-auth0 without Composer

laravel-simple-auth0

A simple/lightweight way to integrate Auth0 into your Laravel Application:

• Minimal configuration.
• Based on Laravel's default authentication guard ('session' / SessionGuard) - ie: no special authentication drivers required.
• Provides a genuine User model. (A lot of Laravel libraries (including Nova) break if a user-provider provides something else.)
• The only dependency is Auth0's PHP SDK.

This library was developed after spending a many hours re-integrating our Laravel apps with each major update of Auth0's official Laravel SDK (auth0/login package). Our applications are stateful "PHP Web Applications" (rather than stateless "PHP Backend APIs" interfacing to an SPA with JWTs), and we did not need a lot of the advanced features included in the Laravel SDK, so we decided to develop a simple package based around the Auth0 QuickStart for a simple PHP Web Application.

If you would like a simple way to integrate Auth0 with Laravel but would prefer not to use this library, you can simply clone our three controllers, register these routes manually, and customise them to your hearts content. You'll soon see that

Installation:

Assuming you have a standard Laravel application (with the default 'session' driver in config/auth.php), you can add this package using composer and run the database migration to prepare the users table for Auth0 (vs password-based) logins.

[!NOTE]

In modifying the users table, the published migration adds the sub field, drops the unique constraint on the email field, and drops the password and email_verified fields. if your users field contains existing user/password entries you with to retain, you should modify the default migration to retain your existing fields.

Modify Models\User.php to reflect these changes:

Configuration:

1. Create a "Regular Web Application" in your Auth0 Dashboard, and configure the allowed Callback + Logout URLs as required. (See Laravel Auth0 SDK docs for more details)

2. Use these details to configure your .env file, replacing them with your own credentials:

3. Add the following lines to your web.php file:

Basic Usage:

You can now use any of Laravel's normal authentication methods to check if logged in, protect routes, retrieve a user, etc:

Don't forget, Authentication (AuthN) is about knowing who is using a system. Whether or not a user has permission to use the system is a separate topic referred to as Authorization (AuthZ) - see Laravel Authorization documentation.

For a simple table/model-based approach to user permissions / Authorization you might like to try our Laravel Simple Permissions package.

[!NOTE]

These packages are both part of our overall AuthN/AuthZ pattern that we deploy for our apps. (Our Faith FM Laravel Auth0 Pattern package is more opinionated than the underlying packages, and includes a number of published template files that may be less helpful for a wider audience, but you're welcome to use them if they are helpful.)

How it works:

Three routes are registered: /login, /logout, /callback

• The /login route redirects to the Auth0 login page, which redirects back to the /callback route on success.

[!IMPORTANT]

This route seeks to capture the 'previous' URL as the 'intended' URL for the callback to redirect to after a successful login

• The /callback route:
  • Validate callback request parameters and retrieves an Auth0 user (using Auth0 PHP SDK)
  • Load (or creates) a matching User model
  • Auth0's sub property is used for model retrieval.
  • Auth0's email + name properties are additionally used for model creation.
  • Initialise Laravel's default authentication guard ('session' / SessionGuard) to "login" this retrieved User model.
  • Laravel's SessionGuard stores model's id in the session, and uses it to retrieve the User model for all future requests.
