How do I handle errors in an EventEmitter?

How do I handle errors in an EventEmitter?

You can handle errors in an EventEmitter by listening for the 'error' event. Here's an example:

const EventEmitter = require('events');
const myEmitter = new EventEmitter();

myEmitter.on('error', (err) => {
  console.error('An error occurred:', err);
});

myEmitter.emit('error', new Error('Something went wrong!'));

What happens if I don't handle the error event?

If you don't handle the 'error' event, the Node.js process will throw an unhandled exception and crash.

Can I use try-catch with EventEmitter?

No, try-catch won't work for asynchronous errors in EventEmitter. You should always listen for the 'error' event.

Are there best practices for error handling in EventEmitter?

Yes, always listen for the 'error' event, log errors appropriately, and consider using a centralized error handling strategy.
