Automate Symfony\Component\EventDispatcher\EventSubscriberInterface::getSubscribedEvents() with simple Trait

Do you like Symfony\Component\EventDispatcher\EventSubscriberInterface and it's getSubscribedEvents() method?

class AwesomeSubscriber implements Symfony\Component\EventDispatcher\EventSubscriberInterface

{



    public static function getSubscribedEvents(): array

    {

        return [

            HappyEvent::class => 'happy',

            CoolEvent::class => 'coll',

        ];

    }



    public function happy(HappyEvent $event): void {}



    public function coll(CoolEvent $event): void {}



}

I hate it!

1. Array with textual method name representation


2. Event class-name written multiple times 😑

Yes, new Symfony has attribute #[AsEventListener], but what if you use another framework or older version of event-dispatcher or you don't like attributes?

There is simple solution 💥

See this trait and install

composer require zarganwar/symfony-event-dispatcher-utils

Enjoy! 🎉
