⚠️ DEPRECATED:

Unique jobs have been implemented in laravel/framework. Please use the official implementation in Laravel 8.14.0 or higher. No further updates will be made to this repository and it will be archived in the future.

Laravel Unique Queue

This redis queue driver works just like the standard Laravel redis queue driver, however, it prevents the same job from being queued multiple times.

Requirements

Needs PHP >= 7.1 to be installed.

Requires illuminate/redis and illuminate/queue, both "~5.7", "~6" or "~7"

Installation

Require via Composer

composer require mlntn/laravel-unique-queue

Configure

Create a new connection in config/queue.php

return [
    // ...
    'connections' => [
        'my_unique_queue_connection_name' => [
            'driver'      => 'unique',
            'connection'  => 'default',
            'queue'       => env('UNIQUE_QUEUE_NAME', 'my_unique_queue_name'),
            'retry_after' => 90,
        ],
        //...
    ]
];

Implementation

Implement a uniquely-queueable job

Your job should use the UniquelyQueueable trait and have the getUniqueIdentifier method:

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Mlntn\Queue\Traits\UniquelyQueueable;

class MyUniqueJob implements ShouldQueue {

    use Dispatchable, InteractsWithQueue, Queueable, UniquelyQueueable, SerializesModels;

    /* ... */

    public function getUniqueIdentifier()
    {
        return 'some-unique-identifier';
    }

}

If the connection is not the default, you will need to specify the connection when dispatching the job:

dispatch(new UniqueJob)->onConnection('my_unique_queue_connection_name');

Implement a unique-queueable listener

Just like with a job the listener class should use the UniquelyQueueable trait and make sure you've set the connection and queue:

<?php

namespace App\Listeners;

use Illuminate\Contracts\Queue\ShouldQueue;
use Mlntn\Queue\Traits\UniquelyQueueable;

class MyListener implements ShouldQueue {

    public $connection = 'my_unique_queue_connection_name';

    public $queue = 'my_unique_queue_name';

    public function handle($event)
    {
        //
    }

    public function getUniqueIdentifier()
    {
        return 'some-unique-identifier';
    }
}

Using Lumen

Lumen handles binding slightly different. Use LumenQueueServiceProvider to enable unique queueing in Lumen.

Register service provider in app.php:

$app->register(Mlntn\Providers\LumenQueueServiceProvider::class);

Using Horizon

Set up a worker configuration:

    'worker_name' => [
        'connection' => 'my_unique_queue_connection_name',
        'queue'      => ['default'],
        'balance'    => 'auto',
        'processes'  => 16,
        'tries'      => 3,
    ],

Run Queue Worker

The unique queue behavior acts internally. Run queue worker as known using artisan (via cli, supervisor or another method). For more detailed information head over to https://github.com/illuminate/queue Specify the connection name used in config/queue.php

php artisan queue:work my_unique_queue_connection_name
