Grouping definitions

If you have more than one module you can register all your controllers and services in a single place by using the classes Controllers and Services.

In order to group all your application services you can extend the class ComPHPPuebla\Slim\Services and add all your modules service providers in the init method by calling the method add

namespace Application;

use ComPHPPuebla\Services;

class ApplicationServices extends Services
{
    /**
     * Add the providers for your modules here
     */
    protected function init()
    {
        $this
            ->add(new ProductCatalogServices())
            //Register more modules here...
            ->add(new DoctrineDbalProvider()) // You could integrate libraries
            ->add(new TwigProvider()) // Using the same approach as with modules
        ;
    }
}

Similarly you can group all your controllers definitions using the class ComPHPPuebla\Slim\Controllers. Similarly, you need to add your modules controllers in the init method (which is called automatically).

namespace Application;

use ComPHPPuebla\Slim\Controllers;

class ApplicationControllers extends Controllers
{
    protected function init()
    {
        $this
            ->add(new ProductCatalogControllers())
            //Register more controllers modules here...
        ;
    }
}

Then your index.php file would only need:

$app = new Slim\Slim();
$resolver = new ComPHPPuebla\Slim\Resolver();

$services = new Application\ApplicationServices($resolver, $parameters);
$services->configure($app);

$controllers = new Application\ApplicationControllers($resolver);
$controllers->register($app);

$app->run();

Note that the Services class allows you to pass parameters to your services through the constructor. These values are passed when we call the configure method to each of the registered services.
