How can I debug EventEmitter errors in my Node.js application?

I'm getting an error with EventEmitter in my Node.js app. How do I debug it?

Debugging EventEmitter errors can be tricky. First, check if you're properly emitting events and if listeners are correctly set up.

What if the event is emitted but the listener isn't triggered?

In that case, ensure that the listener is added before the event is emitted. Also, check for any typos in event names.

Are there any tools that can help me debug these issues?

Yes, you can use Node.js built-in debugging tools or libraries like 'debug' to log events and track their flow.

Can you give me an example of how to use the 'debug' library?

Sure! First, install it using npm. Then, you can use it like this: const debug = require('debug')('app:event'); debug('Event emitted'); This will log messages when the event is emitted.
