Supporting Enqueue

Enqueue is an MIT-licensed open source project with its ongoing development made possible entirely by the support of community and our customers. If you'd like to join them, please consider:

EnqueueBundle. Quick tour.

The EnqueueBundle integrates enqueue library. It adds easy to use configuration layer, register services, adds handy cli commands.


$ composer require enqueue/enqueue-bundle enqueue/amqp-ext # or enqueue/amqp-bunny, enqueue/amqp-lib

Note: You could use not only AMQP transport but any other available.

Note: If you are looking for a way to migrate from php-amqplib/rabbitmq-bundle read this article.

Enable the Bundle

Then, enable the bundle by adding new Enqueue\Bundle\EnqueueBundle() to the bundles array of the registerBundles method in your project's app/AppKernel.php file:


// app/AppKernel.php

// ...
class AppKernel extends Kernel
    public function registerBundles()
        $bundles = array(
            // ...

            new Enqueue\Bundle\EnqueueBundle(),

        // ...

    // ...


First, you have to configure a transport layer and set one to be default.

# app/config/config.yml

        transport: "amqp:"
        client: ~

Once you configured everything you can start producing messages:

use Enqueue\Client\ProducerInterface;

/** @var ProducerInterface $producer **/
$producer = $container->get(ProducerInterface::class);

// send event to many consumers
$producer->sendEvent('aFooTopic', 'Something has happened');

// send command to ONE consumer
$producer->sendCommand('aProcessorName', 'Something has happened');

To consume messages you have to first create a message processor:

use Interop\Queue\Message;
use Interop\Queue\Context;
use Interop\Queue\Processor;
use Enqueue\Client\TopicSubscriberInterface;

class FooProcessor implements Processor, TopicSubscriberInterface
    public function process(Message $message, Context $session)
        echo $message->getBody();

        return self::ACK;
        // return self::REJECT; // when the message is broken
        // return self::REQUEUE; // the message is fine but you want to postpone processing

    public static function getSubscribedTopics()
        return ['aFooTopic'];

Register it as a container service and subscribe to the topic:

    class: 'FooProcessor'
        - { name: 'enqueue.client.processor' }

Now you can start consuming messages:

$ ./bin/console enqueue:consume --setup-broker -vvv

Note: Add -vvv to find out what is going while you are consuming messages. There is a lot of valuable debug info there.
