How can I handle authentication errors in Firebase with hooks?

You can handle authentication errors in Firebase by using the useEffect hook to listen for changes in the authentication state.

Can you give me a code example of that?

Sure! Here's a simple example:

import { useEffect } from 'react';
import { useAuth } from './auth';

const MyComponent = () => {
  const { user, error } = useAuth();

  useEffect(() => {
    if (error) {
      console.error('Authentication error:', error);
      // Handle the error (e.g., show a message to the user)
    }
  }, [error]);

  return <div>{user ? 'Welcome!' : 'Please log in.'}</div>;
};

What types of errors should I be prepared to handle?

You should be prepared to handle errors like invalid credentials, user not found, and network issues.
