Question 1

How to use EVT with React hooks?

Accepted Answer

EVT provides dedicated hooks like useEvt that integrate seamlessly with React lifecycle, allowing automatic subscription and cleanup. You can import them from the evt package and use them in functional components for type-safe event handling.

Question 2

EVT vs RxJS: which one should I choose?

Accepted Answer

Choose EVT if you need type safety and a simpler API without RxJS's steep learning curve, ideal for event-driven apps in TypeScript. Opt for RxJS if you require advanced operators for complex data transformations and reactive streams.

Question 3

Can EVT replace EventEmitter in existing Node.js code?

Accepted Answer

Yes, EVT is designed as a drop-in replacement with a similar API, so you can swap 'events' for 'evt' to add type safety and enhanced features. The migration is straightforward, but you'll need to update imports and potentially adjust listener management.

Question 4

How do I remove an anonymous listener in EVT?

Accepted Answer

EVT allows precise listener control via methods like .attach() and .detach(), even for anonymous functions, by keeping references. This is a key improvement over EventEmitter, which requires named functions for removal.

Question 5

Does EVT work in browsers without Node.js?

Accepted Answer

Yes, EVT is runtime agnostic and works in browsers, Deno, Node.js, and React Native. It has no external dependencies and is available via npm or direct import for Deno, making it flexible for web projects.

Question 6

What TypeScript version is required for EVT?

Accepted Answer

EVT requires TypeScript version 3.8 or higher, released in February 2020. Ensure your project meets this requirement to use all features, as older versions might not support the type inference fully.

Question 7

How to handle event timeouts with EVT promises?

Accepted Answer

Use Evt.waitFor() with a timeout parameter to wait for events with a maximum duration, or combine it with conditions for more control. This promise-based approach simplifies asynchronous event handling compared to traditional callbacks.
