Events

Recording Events

In your entity use RecordsEvents; and record events when needed:

class User
{
    use RecordsEvents;
    
    public static function create(
        UserId $id,
    ): self {
        // ...
        $user->recordThat(new UserWasCreated(
            userId: $user->getUserId(),
        ));

        return $user;
    }
}

Publishing Events

In your repository, inject the EventBus and publish the recorded events:

final readonly class UserRepository implements CommandHandler
{
    public function __construct(
        private EventBus $eventBus,
    ) {
    }
    
    public function save(User $user): void
    {
        // ...
        $this->eventBus->publishEvents($user->getRecordedEvents());
    }    

Registering Event Listeners

Create a manager / event listener and add the AsEventListener attribute:

final readonly class UserEmailManager
{
    #[AsEventListener]
    public function reactToUserWasCreated(UserWasCreated $event): void
    {
        // ...
    }
}

Rate Limiter

Create a Rate Limiter

Define a new rate limiter in config/packages/rate_limiter.yaml:

framework:
  rate_limiter:
    anonymous:
      policy: 'sliding_window'
      limit: 100
      interval: '60 minutes'

Apply a limiter to a route

Then apply it to the necessary routes:

    #[RateLimiter('anonymous')]
    #[Route(path: '/your/important/route', methods: ['GET', 'POST'])]
    public function handle(Request $request): Response
    {
      // ...
    }
