AsyncTasksBundle

About

The AsyncTasksBundle allows to send asynchronous messages in your Symfony2 Application via RabbitMq (using the php-amqplib library).

PUBLISHING

The message publishing is so easy.

• Create an async event Trt\AsyncTasksBundle\Event\AsyncEvent
• Dispatch it!
• Done

    $event = new AsyncEvent(
        'async_event_name',
        array('date'=> (new \DateTime())->format('d-m-Y H:s')
        )
    );
    $this->get('event_dispatcher')->dispatch($event->getName(), $event);

CONSUMING

Now if you want consume the messages

• Write your domain specific service implementing the Trt\AsyncTasksBundle\Listener\ListenerInterface interface.
• Tag the service with {name: trt_async.listener.listen, event: async_event_name} , the event key is the event name.
• Run

$ app/console trt:async:run async_event_name

All the examples expect a running RabbitMQ server.

Installation

This instructions have been tested on a project created with the Symfony2 Standard 2.3.4

Add the AsyncTasksBundle to your composer.json and type composer install.

    "require": {
        "php": ">=5.3.3",
        ....
        "trt/async-tasks-bundle": "dev-master",
        ...
    },

Add the AsyncTasksBundle to your application's kernel:

public function registerBundles()
{
    $bundles = array(
        ...
        new Trt\AsyncTasksBundle\TrtAsyncTasksBundle(),
        ...
    );
    ...
}

Configuration

trt_async_tasks:
    # This prefix allows the dispatcher to detect async event,
    # if you want use another prefix put here
    event:
        prefix: async_
    mq:
        # The rabbitMq host / port
        connection_params:
            host: %mq_host%
            port: %mq_port%
        # Define the exchange name for rabbitmq
        exchange:
            exchange: 'exchange_symfony_events'

Naming Conventions

AsyncTasksBundle's event detection mechanism is based on naming convention, the event name will be the same of queue name. every event with name containing the async string will be detected as AysncEvent.

The name prefix cold be overridden via config

trt_async_tasks:
    event:
        prefix: acme_async

This bundle will be shown at SymfonyDayIt 2013 (Rome)

Fork it and contribute to solve the issues :-)
