EventSubscriber

ZF2 Module. One place for manage application events.

Instalation

Add to your composer.json:

"t4web/event-subscriber": "~1.0.0"

And to your config/application.config.php:

'modules' => [
    // ...
    'T4web\EventSubscriber',
    // ...
],

Problem

As usual your event handlers everywhere, and you (or team member) don't know what will be executed when you see this code $this->getEventManager()->trigger($event);. You spend many time with Crtl+F in whole project.

Solution

It just recommendation (or team rule) - describe all your handlers in one place in your module.config.php:

    'events' => [
        'Zend\Mvc\Application' => [
            'render' => [
                SomeListenerOne::class,
            ],
        ],
        'Users\User\Infrastructure\Repository' => [
            'create' => [
                SomeListenerTwo::class,
                SomeListenerThree::class,
            ],
        ],
        'Users\User\Infrastructure\Repository' => [
            'status:change' => [
                CreateTimelineEntryListener::class,
                UserNotifyListener::class,
                ExpireUserTokensListener::class,
                AdminLogListener::class,
            ],
        ],
        
        // ...
        'EventIdentifier' => [
            'EventName' => [
                'Callback1', // can be invokable class
                'Callback2',
                // ...
                'CallbackN',
            ],
        ],
    ],

T4web\EventSubscriber - read this config and attach every handler in described event.
