README

simple extension to the Illuminate/Queue queue system used in Laravel and Lumen.

Using this connector allows SQS messages originating from a SNS subscription to be worked on with Illuminate\Queue\Jobs\SqsJob.

This is especially useful in a miroservice architecture where multiple services subscribe to a common topic with their queues and publish an event to SNS.

Requirements

Laravel (tested with version 5.8)
or Lumen (tested with version 5.8)

Installation

You can install the package via composer

composer require jeylabs/laravel-sns-sqs-sub-pub

You can optionally publish the config file with:

php artisan vendor:publish --provider="Jeylabs\SnsSqsPubSub\SnsSqsPubSubServiceProvider" --tag="config"

This is the contents of the published config file:

<?php
return [
    'default_topic' => 'SampleTopic',
    'default_auth_driver' => null,
    'map' => [
        \App\Jobs\TestSQSJob::class => 'SampleTopic',
    ],
    'published_attributes' => [
        'id',
        'created_at',
        'updated_at'
    ],
    'sns' => [
        'key' => env('SNS_SQS_PUB_SUB_AWS_ACCESS_KEY'),
        'secret' => env('SNS_SQS_PUB_SUB_AWS_SECRET_ACCESS_KEY'),
        'region' => env('SNS_SQS_PUB_SUB_AWS_DEFAULT_REGION', 'us-east-1'),
    ]
];

Configuration

You'll need to configure the queue connection in your config/queue.php

<?php
return [
    'connections' => [
      'sns-sqs-sub-pub' => [
          'driver' => 'sns-sqs-sub-pub',
          'key' => env('SNS_SQS_PUB_SUB_AWS_ACCESS_KEY'),
          'secret' => env('SNS_SQS_PUB_SUB_AWS_SECRET_ACCESS_KEY'),
          'prefix' => env('SNS_SQS_PUB_SUB_SQS_PREFIX', 'https://sqs.ap-southeast-1.amazonaws.com/your-account-id'),
          'queue' => env('SNS_SQS_PUB_SUB_QUEUE_URL', 'your-queue-name'),
          'region' => env('SNS_SQS_PUB_SUB_AWS_DEFAULT_REGION', 'us-east-1'),
      ],
    ],
];

Once the sns-sqs-sub-pub queue connector is configured you can start using it by setting queue driver to 'sns-sqs-sub-pub' in your .env file.

Job class example

<?php
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Support\Facades\Log;

class TestSQSJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $passedInData;

    /**
     * Create a new job instance.
     *
     * @param array $data
     */
    public function __construct(array $data)
    {
        // $data is array containing the msg content from SQS
        $this->passedInData = $data;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        Log::info(json_encode($this->passedInData));
        // Check laravel.log, it should now contain msg string.
    }
}

Published event

<?php
namespace App;

use Illuminate\Database\Eloquent\Model;
use Jeylabs\SnsSqsPubSub\Traits\SNSPublisher;

class Post extends Model
{
    use SNSPublisher;

    /**
     * @var array
     * Optional (default value is [] )
     * Witch are the attributes should only from SNS message
     */
    static $publishedAttributes = [
        'id',
        'created_at',
        'updated_at'
    ];

    /**
     * @var array
     * Optional  (default value is [created','updated','deleted','restored'] )
     * Witch events should send to SNS
     */
    static $publishEvents = ['created', 'updated'];

    /**
     * @var string
     * Optional (default value is load from config )
     * Publish SNS topic
     */
    static $publishTopic = 'SampleTopic';
    /**
     * Or
     * static $publishTopic = [
     *  'created' => 'SampleTopic'
     * ];
     */
}

You'll need to configure .env file

SNS_SQS_PUB_SUB_AWS_SNS_DEFAULT_TOPIC=sampletopic
SNS_SQS_PUB_SUB_AWS_ACCESS_KEY=
SNS_SQS_PUB_SUB_AWS_SECRET_ACCESS_KEY=
SNS_SQS_PUB_SUB_AWS_DEFAULT_REGION=ap-southeast-1
SNS_SQS_PUB_SUB_SQS_PREFIX=https://sqs.ap-southeast-1.amazonaws.com/your-account-id
SNS_SQS_PUB_SUB_QUEUE_URL=https://sqs.ap-southeast-1.amazonaws.com/your-account-id/your-queue-name
