Small and simple Event Bus library.

Narrator allows communication between components without requiring the component to explicitly depend on each other.

Installation
------------

[](#installation)

Using [Composer](http://getcomposer.org/):

```
$ composer require narrator/narrator
```

Basic usage
-----------

[](#basic-usage)

```
// Simple event object
class UserRegistered {
    private $userId;

    private $userName;
    // ...event data, constructor, getters
}
// Sample listener
class UserRegisteredListener implements Listener {

    public function handle($event, Meta $meta){
        // send email, update model, etc
    }
}

// create EventBus which will be responsible for managing events and listeners
$eventBus = new BasicEventBus(new NameBasedResolver(new ClassNameExtractor()));

// create listener instance
$listener = new UserRegisteredListener(...);
// and register it in bus
$eventBus->subscribe(UserRegistered::class, $listener);

// create event
$event = new UserRegistered(...);
// and `emit` it to listeners
$eventBus->emit($event);
```
