Laravel - Events - Queued Event Listeners
Queueing listeners can be beneficial if your listener is going to perform a slow task such as sending an email or making an HTTP request. Before using queued listeners, make sure to configure your queue and start a queue worker on your server or local development environment.
To specify that a listener should be queued, add the
ShouldQueue interface to the listener class. Listeners generated by the
make:listener Artisan commands already have this interface imported into the current namespace so you can use it immediately:
That's it! Now, when an event handled by this listener is dispatched, the listener will automatically be queued by the event dispatcher using Laravel's queue system. If no exceptions are thrown when the listener is executed by the queue, the queued job will automatically be deleted after it has finished processing.
