Laravel Listener Pattern Skill

Use this skill when implementing Event-Driven Architecture.

Workflow

1. Create Event: php artisan make:event [EventName]
2. Create Listener: php artisan make:listener [ListenerName] --event=[EventName]

Rules

1. Queued Listeners

• If the listener performs IO (Email, API, Notification), it MUST implement ShouldQueue.

class SendWelcomeEmail implements ShouldQueue
{
    // ...
}

2. Dependency Injection

• Inject dependencies in __construct.
• Access event data in handle(EventName $event).

3. Verification

• Ensure the mapping exists. Laravel 11/12 detects it automatically if the listener type-hints the event.
