README

Gember Event Sourcing Message Bus adapter based on symfony/messenger.

All external dependencies in Gember Event Sourcing are organized into separate packages, making it easy to swap out a vendor adapter for another.

Installation

Install with Composer:

composer gember/message-bus-symfony

Configuration

Bind this adapter to the EventBus interface in your service definitions.

Examples

Vanilla PHP

use Gember\MessageBusSymfony\SymfonyEventBus;
use Symfony\Component\Messenger\Handler\HandlersLocator;
use Symfony\Component\Messenger\MessageBus;
use Symfony\Component\Messenger\Middleware\HandleMessageMiddleware;

$finder = new SymfonyEventBus(
    new MessageBus([ // An EventBus configuration of your choice
        new HandleMessageMiddleware(new HandlersLocator([
            SomeEvent::class => [SomeEventSubscriber::class],
            // ...
        ])),     
    ]), 
);

Symfony

It is recommended to use the Symfony bundle to configure Gember Event Sourcing. With this bundle, the adapter is automatically set as the default for Event Bus.

If you're not using the bundle, you can bind it directly to the EventBus interface.

Gember\EventSourcing\Util\Messaging\MessageBus\EventBus:
  class: Gember\MessageBusSymfony\SymfonyEventBus
  arguments:
    - '@event.bus' # or any other defined Symfony event bus

gember / message-bus-symfony
