4.2. Event Publishing
Prooph\EventStoreBusBridge\EventPublisher is an event store plugin which listens on the event store
commit.post action event.
It iterates over the
recordedEvents and publishes each on the
4.2.1. Set Up
The EventPublisher requires an instance of
Prooph\ServiceBus\EventBus at construction time.
Furthermore, the publisher implements
Prooph\EventStore\Plugin\Plugin. So you need to pass the event store to the
EventPublisher::setUp method. That's it. From this moment on all domain events are published on the event bus when
an event store transaction is committed.
18.104.22.168. Container-Driven Set Up
If you are using the
container-aware factory shipped with prooph/event-store you may also
want to auto register the
EventPublisher. First you need to make the event publisher available as a service in the
container. You can use the
Prooph\EventStoreBusBridge\Container\EventPublisherFactory for that.
Note: The event bus should be available as service
Prooph\ServiceBus\EventBus in the container. But if your event bus is
registered with another service name you can extend the factory and override the protected method
Map the factory to a service name like
prooph.event_publisher and add this service name to the list of event store plugins
in your application configuration. Also have a look at the event store docs for more details about the plugin system.
