- **PSR-14** Event Dispatcher and Listener
- using [`InvokerInterface`](https://github.com/PHP-DI/Invoker/blob/2.0.0/src/InvokerInterface.php) to execute anything, **PSR-11** compatible

Check [satellite-app](https://github.com/bemit/satellite-app) for a ready to use template, or install just this event library:

```
composer require orbiter/satellite
```

Dependencies, using [`PHP-DI`](https://php-di.org/) here, but possible with any PSR-11 container and any implementation of [`InvokerInterface`](https://github.com/PHP-DI/Invoker):

```
use function DI\autowire;
use function DI\get;

$dependencies = [
    Satellite\Event\EventListenerInterface::class => autowire(Satellite\Event\EventListener::class),
    Psr\EventDispatcher\ListenerProviderInterface::class => get(Satellite\Event\EventListenerInterface::class),
    Satellite\Event\EventDispatcher::class => autowire()
        ->constructorParameter('listener', get(Psr\EventDispatcher\ListenerProviderInterface::class))
        ->constructorParameter('invoker', get(Invoker\InvokerInterface::class)),
    Psr\EventDispatcher\EventDispatcherInterface::class => get(Satellite\Event\EventDispatcher::class),
];

```

For full invocation PSR-11 injection based on `Reflection`, set up the `Invoker` with the included `InvokerTypeHintContainerResolver`:

```
/**
 * @var $invoker \Invoker\Invoker
 */
$invoker = $container->get(\Invoker\Invoker::class);
$invoker->getParameterResolver()->prependResolver(
    new Satellite\InvokerTypeHintContainerResolver($container)
);

```
