Laravel Queued Events

Dispatching Events into queues. This is especially useful for distributed systems events using fanout queues.

Installation

1. Install the package

   composer require acdphp/laravel-queued-events

Usage

1. Extend QueuedEvent to your event.

   use Acdphp\QueuedEvents\Events\QueuedEvent;
   
   class UserCreatedEvent extends QueuedEvent
   {
       // Remove the Dispatchable trait
   
       public function __construct(public $object)
       {
       }
   }

2. Call dispatch()

   UserCreatedEvent::dispatch(['foo' => 'bar']);

   • You may specify a queue connection and queue:

   UserCreatedEvent::dispatch(['foo' => 'bar'])
       ->onConnection('your-fanout-queue-connection')
       ->onQueue('your-custom-queue');

   • Utilities are also available: dispatchIf(), dispatchUnless()

   // Dispatches if $condition is true
   UserCreatedEvent::dispatchIf($condition, ['foo' => 'bar']);
   
   // Dispatches if $condition is false
   UserCreatedEvent::dispatchUnless($condition, ['foo' => 'bar']);

3. Default dispatch methods are prefixed with internal

   UserCreatedEvent::internalDispatch(['foo' => 'bar']);
   
   UserCreatedEvent::internalDispatchIf(['foo' => 'bar']);
   
   UserCreatedEvent::internalDispatchUnless(['foo' => 'bar']);

Configuration

php artisan vendor:publish --tag=queued-events-config

QUEUED_EVENTS_QUEUE_CONNECTION

The default queue connection will be whatever your QUEUE_CONNECTION is set. You may override this by setting QUEUED_EVENTS_QUEUE_CONNECTION

QUEUED_EVENTS_QUEUE

The default queue will be default. You may override this by setting QUEUED_EVENTS_QUEUE

Notes

• Using Laravel helpers, like event(...) or app('events')->dispatch(...), will dispatch the job internally. Only use ::dispatch, ::dispatchIf and ::dispatchUnless to dispatch on queue.
• Use Laravel's queued listener if you're only using this in a monolithic application.
