Laravel 5 middleware that overrides pingpong-labs/modules configurations over the app's Config.

OverrideModuleConfiguration.php

<?php

namespace App\Http\Middleware;

/**
 * When using pingpong-labs/modules, you may want to override app config when the request is made
 * in the context of a module.
 *
 * This middleware will do that. For example, if the module/MyModule/Config/config.php has the code:
 *
 * <?php
 * return [
 *      'auth' => [
 *          'model' => Modules\MyModule\Entities\Access\User::class
 *      ]]
 *
 * then config('auth.model'); will return Modules\MyModule\Entities\Access\User::class
 *
 * The rest of the config('auth') variables will remain the same.
 *
 * You can use the middleware in the routes file like this:
 *
 * In the app/Http/Kernel.php add the line:
 * protected $routeMiddleware = [
 *      (...)
 *      'override.module.configs' => \App\Http\Middleware\OverrideModuleConfiguration::class,
 *
 * In the routes.php file add something like:
 * Route::group(['prefix' => 'mymodule', 'middleware' => 'override.module.configs:mymodule'],
 *
