What are some examples of using Firebase with React hooks?

Can you give me some examples of using Firebase with React hooks?

Sure! One common example is using the useEffect hook to fetch data from Firestore when a component mounts.

How would I set up a listener for real-time updates?

You can use the onSnapshot method in a useEffect hook to listen for real-time updates from Firestore.

What about authentication? Can I use hooks for that?

Absolutely! You can create a custom hook to manage authentication state and handle login/logout actions.

Can you show me a code snippet for the authentication hook?

Sure! Here's a simple example of a custom hook for Firebase authentication:

import { useState, useEffect } from 'react';
import { auth } from './firebase'; // your firebase config

const useAuth = () => {
  const [user, setUser] = useState(null);

  useEffect(() => {
    const unsubscribe = auth.onAuthStateChanged(setUser);
    return () => unsubscribe();
  }, []);

  return user;
};

This hook will return the current user or null if not authenticated.
