The App package provides integration with Slim and Pimple for building user-facing Web applications and APIs.

• PSR-7 kernel (web, API, CLI)
• PSR-11 container
• Translation layer^[†]

Service Providers

Dependencies and extensions are handled by a dependency container, using Pimple, which can be defined via service providers (Pimple\ServiceProviderInterface).

Included Providers

The Charcoal App comes with several providers out of the box. All of these are within the Charcoal\App\ServiceProvider namespace:

• AppServiceProvider
• DatabaseServicePovider
• FilesystemServiceProvider
• LoggerServiceProvider

External Providers

The Charcoal App requires a few providers from independent components. The following use their own namespace and are automatically injected via the AppServiceProvider:

• CacheServiceProvider
• TranslatorServiceProvider
• ViewServiceProvider

Usage

Typical front-controller (www/index.php):

use Charcoal\App\App;
use Charcoal\App\AppConfig;
use Charcoal\App\AppContainer;

include '../vendor/autoload.php';

$config = new AppConfig();
$config->addFile(__DIR__.'/../config/config.php');
$config->set('ROOT', dirname(__DIR__) . '/');

// Create container and configure it (with charcoal/config)
$container = new AppContainer([
    'settings' => [
        'displayErrorDetails' => true,
    ],
    'config' => $config,
]);

// Charcoal / Slim is the main app
$app = App::instance($container);
$app->run();
