Question 1

How to use Mitt for global event handling in a React app?

Accepted Answer

Import Mitt, create an emitter instance, and pass it between components via props or context. Since Mitt is framework-agnostic, you can use it as a lightweight event bus, but note that React's own state management might be more integrated for complex cases.

Question 2

Mitt vs EventEmitter: which is better for browser projects?

Accepted Answer

Mitt is optimized for minimal size and functional design in browsers, weighing under 200 bytes, while Node's EventEmitter is built-in for Node.js but larger for bundling. Choose Mitt if bundle size is critical; otherwise, EventEmitter offers more features.

Question 3

Does Mitt support one-time event listeners?

Accepted Answer

No, Mitt does not have built-in support for once-only listeners. You need to manually remove the listener after it fires or wrap it in a custom function to achieve similar behavior.

Question 4

Can Mitt handle asynchronous events?

Accepted Answer

Mitt emits events synchronously by default. To handle async events, you must manage promises or async functions within your listeners, as there's no built-in async support or event queueing mechanism.

Question 5

How small is Mitt compared to other event libraries?

Accepted Answer

Mitt is extremely small at under 200 bytes gzipped, making it significantly lighter than alternatives like EventEmitter3 (~2KB) or RxJS (much larger). This makes it ideal for projects where every byte counts in the bundle.

Question 6

Is Mitt good for large-scale applications?

Accepted Answer

Mitt's minimalism can be a limitation in large apps requiring advanced event management, error handling, or persistence. For complex event-driven architectures, more feature-rich libraries might be better suited.
