How can I use custom hooks with event emitters in React?

You can create a custom hook that utilizes an event emitter to manage state and side effects in your components.

Can you show me a simple example of this?

Sure! First, install an event emitter library like 'events'. Then, create a custom hook that subscribes to events.

What would the code look like?

Here's a basic example:

import { useEffect, useState } from 'react';
import EventEmitter from 'events';

const eventEmitter = new EventEmitter();

const useCustomHook = () => {
    const [data, setData] = useState(null);

    useEffect(() => {
        const handleEvent = (newData) => setData(newData);
        eventEmitter.on('dataEvent', handleEvent);

        return () => {
            eventEmitter.off('dataEvent', handleEvent);
        };
    }, []);

    return data;
};

You can emit events using eventEmitter.emit('dataEvent', newData);.
