RabbitMQ manager for Laravel applications

This package can be used for easy access to the RabbitMQ entities like connections or queues.

Installed php extension ext-amqp is required. Installation steps can be found in Dockerfile.

Install

Require this package with composer using the following command:

$ composer require avto-dev/amqp-rabbit-manager "^2.0"

Installed composer is required (how to install composer).

You need to fix the major version of package.

After that you should "publish" package configuration file using next command:

$ php ./artisan vendor:publish --provider='AvtoDev\AmqpRabbitManager\ServiceProvider'

And configure it in the file ./config/rabbitmq.php.

Usage

At first you should execute command rabbit:setup for creating all queues and exchanges on RabbitMQ server.

Then, in any part of your application you can resolve connection or queue/exchange factories. For example, in artisan command:

<?php

namespace App\Console\Commands;

use AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface;

class SomeCommand extends \Illuminate\Console\Command
{
    /**
     * The console command name.
     *
     * @var string
     */
    protected $name = 'some:command';

    /**
     * Execute the console command.
     *
     * @param ConnectionsFactoryInterface $connections
     *
     * @return void
     */
    public function handle(ConnectionsFactoryInterface $connections): void
    {
        $connections->default(); // Get the default RabbitMQ connection instance
    }
}

Create queue manually

Declare queue operation creates a queue on a broker side (use command rabbit:setup instead this):

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$exchange = $connections
    ->default()
    ->declareQueue($queues->make('some-queue-id'));

Create exchange manually

Declare exchange operation creates a topic on a broker side (use command rabbit:setup instead this):

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\ExchangesFactoryInterface $exchanges */

$exchange = $connections
    ->default()
    ->declareTopic($exchanges->make('some-exchange-id'));

Bind queue to exchange

Connects a queue to the exchange. So messages from that topic comes to the queue and could be processed (use command rabbit:setup events \AvtoDev\AmqpRabbitManager\Commands\Events\* instead this):

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */
/** @var \AvtoDev\AmqpRabbitManager\ExchangesFactoryInterface $exchanges */

$connections
    ->default()
    ->bind(new \Interop\Amqp\Impl\AmqpBind(
        $exchanges->make('some-exchange-id'),
        $queues->make('some-queue-id')
    ));

Send message to exchange

Create message and them to the exchange:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\ExchangesFactoryInterface $exchanges */

$connection = $connections->default();
$message    = $connection->createMessage('Hello world!');

$connection
    ->createProducer()
    ->send($exchanges->make('some-exchange-id'), $message);

Send message to queue

Create message and them to the queue:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$connection = $connections->default();
$message    = $connection->createMessage('Hello world!');

$connection
    ->createProducer()
    ->send($queues->make('some-queue-id'), $message);

Send priority message

Messages priority uses for messages ordering:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$connection = $connections->default();
$message    = $connection->createMessage('Hello world!');

$connection
    ->createProducer()
    ->setPriority(10)
    // ...
    ->send($queues->make('some-queue-id'), $message);

Send expiration message

Also known as message TTL:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$connection = $connections->default();
$message    = $connection->createMessage('Hello world!');

$connection
    ->createProducer()
    ->setTimeToLive(60000) // 60 sec
    // ...
    ->send($queues->make('some-queue-id'), $message);

Send delayed message

You should avoid to use enqueue/amqp-tools delay strategies, if you can. If you makes it manually - you have full control under it.

Get (consume) single message

Get one message and continue script execution:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$consumer = $connections->default()->createConsumer($queues->make('some-queue-id'));

$message = $consumer->receive();

try {
    // .. process a message ..

    $consumer->acknowledge($message);
} catch (\Exception $e) {
    // .. process exception ..

    $consumer->reject($message);
}

Subscription consumer

Start (nearly) infinity loop for messages processing (you can start more then one consumer in a one time, just call ``):

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$connection = $connections->default();
$queue      = $queues->make('some-queue-id');
$consumer   = $connection->createConsumer($queue);
$subscriber = $connection->createSubscriptionConsumer();

$subscriber->subscribe(
    $consumer,
    function(\Interop\Amqp\AmqpMessage $message, \Enqueue\AmqpExt\AmqpConsumer $consumer): bool {
        try {
            // .. process a message ..

            $consumer->acknowledge($message);
        } catch (\Exception $e) {
            // .. process exception ..

            $consumer->reject($message);

            return false; // Subscription will be cancelled
        }

        return true; // Subscription will be continued
    }
);

$subscriber->consume(); // You can pass timeout in milliseconds

Purge queue messages

Remove all messages in queue:

<?php

/** @var \AvtoDev\AmqpRabbitManager\ConnectionsFactoryInterface $connections */
/** @var \AvtoDev\AmqpRabbitManager\QueuesFactoryInterface $queues */

$connection = $connections->default();

$connection->purgeQueue($queues->make('some-queue-id'));

Testing

For package testing we use phpunit framework and docker with compose plugin as develop environment. So, just write into your terminal after repository cloning:

$ make build
$ make latest # or 'make lowest'
$ make test
