Question 1

How to integrate Événement with a Laravel application?

Accepted Answer

Événement can be used alongside Laravel by creating custom event emitters in service providers or controllers, but it's often redundant since Laravel has a built-in event system. For simple decoupled components, instantiate the emitter and attach listeners as needed.

Question 2

Événement vs Symfony EventDispatcher: which is better for PHP?

Accepted Answer

Use Événement for minimal, Node.js-style event handling in small projects or when you need a lightweight solution. Symfony EventDispatcher is better for complex applications requiring features like event priorities, listener sorting, and deep integration with Symfony components.

Question 3

Can Événement handle asynchronous events?

Accepted Answer

No, Événement emits events synchronously out of the box. To handle events asynchronously, you must implement custom logic using queues or background jobs, which adds complexity beyond the library's scope.

Question 4

How to remove an event listener in Événement?

Accepted Answer

Use the `removeListener()` method by passing the exact event name and callback function instance. As shown in the README, ensure the callback is identical to the one used in `on()` to successfully detach it.

Question 5

Is Événement suitable for large-scale enterprise applications?

Accepted Answer

While Événement promotes decoupling, it may lack advanced tooling like event logging, monitoring, or integration with enterprise systems, making it less ideal for large-scale applications compared to full-featured frameworks.

Question 6

How to test events with Événement in PHPUnit?

Accepted Answer

Test events by mocking the emitter or using assertions to verify that listeners are called with expected arguments. Write unit tests that emit events and check listener responses, leveraging PHPUnit's mocking capabilities for callbacks.
