Laravel RabbitMQ queues

 

In order to connect Laravel with RabbitMQ we will need the following library:

composer require vladimir-yuldashev/laravel-queue-rabbitmq

then
in config/queue.php add the following configuration:

'connections' => [
    // ...

    'rabbitmq' => [
    
       'driver' => 'rabbitmq',
       'queue' => env('RABBITMQ_QUEUE', 'default'),
       'connection' => PhpAmqpLib\Connection\AMQPLazyConnection::class,
   
       'hosts' => [
           [
               'host' => env('RABBITMQ_HOST', '127.0.0.1'),
               'port' => env('RABBITMQ_PORT', 5672),
               'user' => env('RABBITMQ_USER', 'guest'),
               'password' => env('RABBITMQ_PASSWORD', 'guest'),
               'vhost' => env('RABBITMQ_VHOST', '/'),
           ],
       ],
   
       'options' => [
           'ssl_options' => [
               'cafile' => env('RABBITMQ_SSL_CAFILE', null),
               'local_cert' => env('RABBITMQ_SSL_LOCALCERT', null),
               'local_key' => env('RABBITMQ_SSL_LOCALKEY', null),
               'verify_peer' => env('RABBITMQ_SSL_VERIFY_PEER', true),
               'passphrase' => env('RABBITMQ_SSL_PASSPHRASE', null),
           ],
           'queue' => [
               'job' => VladimirYuldashev\LaravelQueueRabbitMQ\Queue\Jobs\RabbitMQJob::class,
           ],
       ],
   
       /*
        * Set to "horizon" if you wish to use Laravel Horizon.
        */
       'worker' => env('RABBITMQ_WORKER', 'default'),
        
    ],

    // ...    
], 

then you need to edit the .env file, supplying your settings under the rabbitMQ section:

RABBITMQ_HOST, RABBITMQ_PORT, RABBITMQ_USER, RABBITMQ_PASSWORD, RABBITMQ_VHOST 

also for the QUEUE_CONNECTION you should supply: rabbitmq

Now lets create a job in the terminal with:

php artisan make:job TestJob

it will handle all the incoming queue events. It's contents under /jobs:

private $data;
    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($data)
    {
        //
         $this->data = $data;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        print_r($this->data);

    } 

Finally we connect and run the created above job handler in order to handle event. Inside EventServiceProvider.php
inside the boot() function add:

$this->app->bind(

TestJob::class."@handle",

fn($job)=>{$job->handle()} // this will run the handle() function from above.

) 

Then inside of a controller you can run:

use App\Jobs\TestJob;

TestJob::Dispatch('hello'); 

you can see inside of the queue with: php artisan queue:work

Cheers!
