# Routing

Our goal is to ease the installation of the different bundles. Users should not have to dive into complicated config files to install bundles.

## A routing loader is available for all bundles

A Chill bundle may rely on the Routing Loader defined in ChillMain.

The loader will load `yml` or `xml` files. You simply have to add them into `chill_main` config

```yaml
   chill_main:
   # ... other stuff here
      routing:
         resources:
            - @ChillMyBundle/Resources/config/routing.yml
```

### Load routes automatically

But this forces users to modify config files. To avoid this, you may prepend config implementing the `PrependExtensionInterface` in the `YourBundleExtension` class. This is an example from **chill main** bundle :

```php
   namespace Chill\MainBundle\DependencyInjection;

   use Symfony\Component\DependencyInjection\ContainerBuilder;
   use Symfony\Component\HttpKernel\DependencyInjection\Extension;
   use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;

   class ChillMainExtension extends Extension implements PrependExtensionInterface
   {

       public function load(array $configs, ContainerBuilder $container)
       {
           // ...
       }

       public function prepend(ContainerBuilder $container)
       {

           //add current route to chill main
           //this is where the resource is added automatically in the config
           $container->prependExtensionConfig('chill_main', array(
              'routing' => array(
                 'resources' => array(
                    '@ChillMainBundle/Resources/config/routing.yml'
                 )

              )
           ));
       }
   }
```
