Laravel's Event system allows you to decouple logic by firing events and handling them through listeners. It improves code separation and flexibility.
Step 1: Events are triggered actions — like "UserRegistered".
Step 2: Listeners respond to those events — like "SendWelcomeEmail".
Step 3: Generate both using:
php artisan make:event UserRegistered
php artisan make:listener SendWelcomeEmail --event=UserRegistered
Step 4: Register events in
EventServiceProvider inside
$listen array.
Step 5: Fire an event using:
event(new UserRegistered($user))
Step 6: Handle event in Listener's
handle() method.
Step 7: Events promote loose coupling — useful for post-registration, logging, or async tasks.
Step 8: For queued listeners, add
implements ShouldQueue to the Listener.
Step 9: Use events for clean separation of concerns — not all logic belongs in controllers.
Step 10: Use events to trigger multiple listeners if needed — one event can notify many actions.
Step 11: Common use cases: sending emails, logging, notifications, webhook calls.
Step 12: Test with:
php artisan event:generate to auto-create missing events/listeners.
Step 13: You can use
broadcast for real-time events with Pusher/WebSockets.
Step 14: Avoid logic in event classes — keep it in the listeners.
Step 15: Events improve scalability by breaking logic into clean, testable units.
