php-ddd/php-ddd-bundle

Library to manage event

PhpDDDBundle

PhpDDDBundle provides some tools to integrate php-ddd/domain-event and php-ddd/command inside your Symfony application., _(*1)

Features

• Services for SequentialCommandBus and CommandHandlerLocator
• Services for EventBus and EventListenerLocator
• A service tag to link Command with CommandHandler easily
• A service tag to link Event with EventListener easily
• A php-ddd:command-bus:debug Symfony command to list every Command/CommandHandler for a given CommandBus
• A php-ddd:event-bus:debug Symfony command to list every Event/EventListener attached to a given EventBus

Usage

Link a CommandHandler to a Command using tags

The easiest way to link a CommandHandler to a Command is by using service tag php_ddd.command_handler on the CommandHandler:, _(*2)

# services.yml
services:
    my.command_handler.foo:
        class: My/CommandHandler/FooCommandHandler
        tags:
            - { name: php_ddd.command_handler, command: My/Command/Foo }

The CommandHandler will be automatically registered in the phpddd_command.handler_locator service which correspond to a CommandHandlerLocator. This CommandHandlerLocator is then passed to the phpddd_command.bus service which correspond to a SequentialCommandBus by default., _(*3)

Add an EventListener listening to an Event using tags

It works the same way as for CommandHandler and Command:, _(*4)

# services.yml
services:
    my.listener.bar:
        class: My/EventListener/BarEventListener
        tags:
            - { name: php_ddd.event_listener, event: Other/Event/Bar }

The EventListener will be automatically registered in the phpddd_event.listener_locator service which correspond to an EventListenerLocator. This EventListener is then passed to the phpddd_event.bus service which correspond to an EventBus by default., _(*5)
