README

A Laravel package for robust AMQP message handling with automatic retry, dead letter queue management, and comprehensive failure tracking.

Features

• Base Consumer Class: Abstract class for building AMQP consumers with built-in error handling
• Automatic Retry: Exponential backoff retry mechanism (1, 5, 15, 60 minutes)
• Dead Letter Queue: Messages that exceed max retries are moved to dead letter status
• Failure Tracking: All failed messages are stored in database for inspection and manual retry
• Artisan Commands: CLI commands for managing failed messages
• Statistics: Get insights into message processing status

Requirements

• PHP 8.2+
• Laravel 11.0+
• bschmitt/laravel-amqp package

Installation

composer require jeromejhipolito/laravel-amqp-toolkit

The package will auto-register its service provider.

Publish Migration

php artisan vendor:publish --tag=amqp-toolkit-migrations
php artisan migrate

Usage

Creating a Consumer

Extend the BaseAmqpConsumer class to create your own consumer:

<?php

namespace App\Console\Commands\Consumer;

use JeromeHipolito\AmqpToolkit\Console\Commands\BaseAmqpConsumer;

class OrderCreatedConsumer extends BaseAmqpConsumer
{
    protected $signature = 'amqp:consume:order-created';
    protected $description = 'Consume order created messages';

    protected function getQueueName(): string
    {
        return 'order-created-queue';
    }

    protected function getRoutingKey(): string
    {
        return 'order.created';
    }

    protected function getExchange(): string
    {
        return 'orders-exchange';
    }

    protected function validatePayload(array $data): bool
    {
        return isset($data['order_id']) && isset($data['user_id']);
    }

    protected function processMessage(array $data): void
    {
        // Your message processing logic here
        logger()->info('Processing order', ['order_id' => $data['order_id']]);
    }

    // Optional: Override max retries (default: 3)
    protected function getMaxRetries(): int
    {
        return 5;
    }
}

Running the Consumer

php artisan amqp:consume:order-created

Artisan Commands

List Failed Messages

# List all failed messages
php artisan amqp:failed

# Filter by queue
php artisan amqp:failed --queue=order-created-queue

# Filter by status
php artisan amqp:failed --status=dead_letter

Retry Failed Messages

# Retry all messages ready for retry
php artisan amqp:retry-failed

# Limit number of messages to retry
php artisan amqp:retry-failed --limit=50

Force Retry Specific Message

# Retry a specific message by ID
php artisan amqp:force-retry 123

# Reset retry count and retry
php artisan amqp:force-retry 123 --reset-count

Purge Dead Letter Messages

# Purge all dead letter messages (with confirmation)
php artisan amqp:purge-dead-letters

# Skip confirmation
php artisan amqp:purge-dead-letters --force

Using AmqpRetryService

You can inject AmqpRetryService for programmatic access:

use JeromeHipolito\AmqpToolkit\Services\AmqpRetryService;

class MessageController extends Controller
{
    public function index(AmqpRetryService $retryService)
    {
        // Get all failed messages
        $messages = $retryService->getFailedMessages();

        // Get messages with filters
        $messages = $retryService->getFailedMessages([
            'queue_name' => 'order-created-queue',
            'status' => 'failed',
        ]);

        // Get statistics
        $stats = $retryService->getStatistics();
        // Returns: ['total' => 10, 'by_status' => ['failed' => 5, 'retrying' => 3, 'dead_letter' => 2]]

        // Manually retry a message
        $message = FailedAmqpMessage::find($id);
        $retryService->retryMessage($message);

        // Purge dead letters
        $deleted = $retryService->purgeDeadLetters();
    }
}

Message Status Lifecycle

1. FAILED: Initial state when a message fails processing
2. RETRYING: Message is being retried
3. DEAD_LETTER: Message has exceeded max retries

Exponential Backoff Schedule

Configuration

The package works out of the box with sensible defaults. You can customize behavior by:

1. Overriding getMaxRetries() in your consumer (default: 3)
2. Overriding shouldAcknowledgeOnFailure() to control message acknowledgment (default: false)

Database Schema

The failed_amqp_messages table stores:
