Basic integration for Auth0 authentication

CodeIgniter Auth0

Basic integration for Auth0 authentication.

Installation

Composer

composer require michalsn/codeigniter-auth0

composer require guzzlehttp/guzzle guzzlehttp/psr7 http-interop/http-factory-guzzle

Manually

In the example below we will assume, that files from this project will be located in app/ThirdParty/auth0 directory.

Download this project and then enable it by editing the app/Config/Autoload.php file and adding the Michalsn\CodeIgniterAuth0 namespace to the $psr4 array, like in the below example:

<?php

namespace Config;

use CodeIgniter\Config\AutoloadConfig;

class Autoload extends AutoloadConfig
{
    // ...
    public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
        'Config'      => APPPATH . 'Config',
        'Michalsn\CodeIgniterAuth0' => APPPATH . 'ThirdParty/auth0/src',
    ];

    // ...

Also add the required helper to the same file under $files array:

    // ...
    public $files = [
        APPPATH . 'ThirdParty/auth0/src/Common.php',
    ];

    // ...

You will still need to install some dependencies:

composer require guzzlehttp/guzzle guzzlehttp/psr7 http-interop/http-factory-guzzle

php spark migrate --all
