Events and Listeners in Laravel: Practical Guide

Laravel’s events provide a simple observer implementation, allowing you to subscribe and listen for various events in your application.

Creating Events

bash

php artisan make:event OrderPlaced

php

class OrderPlaced
{
    use Dispatchable, SerializesModels;

    public function __construct(
        public Order $order
    ) {}
}

Creating Listeners

bash

php artisan make:listener SendOrderNotification --event=OrderPlaced

php

class SendOrderNotification
{
    public function handle(OrderPlaced $event): void
    {
        $event->order->user->notify(
            new OrderConfirmation($event->order)
        );
    }
}

Dispatching Events

php

// Using the event helper
event(new OrderPlaced($order));

// Using the dispatch method
OrderPlaced::dispatch($order);

Event Discovery

Laravel can automatically discover event listeners:

php

public function shouldDiscoverEvents(): bool
{
    return true;
}
