Cascading Config

A simple package that brings the cascading configuration system back into Laravel 5 and its sister project, Lumen.

• Laravel 5, or
• Lumen >=5.1

• Laravel-4 style cascading config (can't believe I'm writing this)
• Nested configuration is fully supported

First, require phanan/cascading-config into your composer.json and run composer update:

    "require": {
        "phanan/cascading-config": "~2.0"
    },

An environment-based configuration directory should have a name with this format config.{APP_ENV}, and reside in the same directory as the default config dir. For Laravel, php artisan vendor:publish will create a sample directory for your local environment. For Lumen, you'll have to create the directories manually.

Your application structure now should have something like this:

config
├── app.php
├── auth.php
├── cache.php
├── compile.php
├── database.php
├── mail.php
└── ...
config.local
├── app.php
├── auth.php
├── cache.php
├── mail.php
└── nested
    └── app.php

Fill the configuration into your environment-based config directory (config.local, config.staging, config.production), just like what you've always done in Laravel 4,

1. Add the package's service provider class into config/app.php:

   'providers' => [
       /*
        * ...
        */
       App\Providers\AppServiceProvider::class,
       App\Providers\EventServiceProvider::class,
       App\Providers\RouteServiceProvider::class,
   
       PhanAn\CascadingConfig\CascadingConfigServiceProvider::class,
   ],

2. Call config($key)

1. Register the service provider class in bootstrap/app.php:

   // $app->register(App\Providers\AppServiceProvider::class);
   // $app->register(App\Providers\EventServiceProvider::class);
   $app->register(PhanAn\CascadingConfig\CascadingConfigServiceProvider::class);

2. Enable multi-environment support by uncommenting this line:

   Dotenv::load(__DIR__.'/../');

3. Manually register the configuration arrays:

   $app->configure('auth');
   $app->configure('cache');
   $app->configure('mail');

4. Call config($key)

Because of the way array_merge_recursive() works, a config key with value being an indexed (non-associative) array (for instance, app.providers) will have the value's items overridden. See #6 for more details on this behavior, and how to work around it.
