README

A Laravel package providing an abstraction layer for AMQP message brokers. Easily switch between RabbitMQ and other AMQP-compatible brokers without changing your application code.

Features

• 🔄 Broker Abstraction - Switch message brokers without code changes
• ⚡ Fiber-based Async - Non-blocking publish/consume using PHP 8.1+ Fibers
• 🔁 Automatic Retries - Configurable connection retry with exponential backoff
• 📦 Bulk Publishing - Efficiently publish collections of messages
• 💀 Dead Letter Queue - Automatic DLQ routing for failed messages
• 🎯 Exchange Support - Publish to queues or exchanges with routing keys

Requirements

• PHP 8.1+
• Laravel 10.x or 11.x
• RabbitMQ (or any AMQP-compatible broker)

Installation

composer require aachich/message-broker

The package will auto-register its service provider.

Publish Configuration

php artisan vendor:publish --provider="Aachich\MessageBroker\MessageBrokerServiceProvider" --tag=config

Environment Variables

Add these to your .env file:

RABBITMQ_HOST=localhost
RABBITMQ_PORT=5672
RABBITMQ_USER=guest
RABBITMQ_PASSWORD=guest
RABBITMQ_VHOST=/
RABBITMQ_QUEUE_CONSUMER=my-consume-queue
RABBITMQ_QUEUE_PUBLISHER=my-publish-queue
RABBITMQ_QUEUE_REJECT=my-dlq
RABBITMQ_MAX_RETRIES=30

Usage

Basic Publishing

use Aachich\MessageBroker\Facades\MessageBroker;

// Connect first
MessageBroker::connect();

// Publish a message
MessageBroker::publishToQueue($message, 'my-queue', ['header-key' => 'value']);

// Publish to an exchange
MessageBroker::publishToExchange($message, 'my-exchange', [], 'routing.key');

Consuming Messages

use Aachich\MessageBroker\Facades\MessageBroker;

MessageBroker::connect();

MessageBroker::consumeMessage('my-queue', function ($message) {
    // Process the message
    $body = $message->getBody();
    
    // Return true to acknowledge, false to reject
    return true;
});

Bulk Publishing

use Illuminate\Support\Collection;

$messages = collect(['msg1', 'msg2', 'msg3']);

MessageBroker::publishBulkMessagesToQueue($messages, 'my-queue');

Check Connection Status

$status = MessageBroker::getStatus();
// Returns: ['brokerName' => 'RabbitMQ', 'connect' => true, 'consuming' => false]

Extending with Custom Brokers

To add support for a new AMQP broker:

1. Create a repository implementing BrokerRepoInterface:

use Aachich\MessageBroker\Contracts\BrokerRepoInterface;

class MyCustomBrokerRepository implements BrokerRepoInterface
{
    // Implement all interface methods
}

1. Update the service provider binding based on config:

$this->app->singleton(BrokerRepoInterface::class, function ($app) {
    return match(config('messagebroker.default')) {
        'rabbitmq' => new RabbitMQRepository(),
        'custom' => new MyCustomBrokerRepository(),
        default => throw new InvalidMessageBrokerNameException(),
    };
});

Testing

vendor/bin/phpunit
