How do I handle authentication errors in a MERN application?
In a MERN application, you can handle authentication errors by implementing error handling middleware in your Express server.
What kind of errors should I be looking for?
You should look for errors like invalid credentials, expired tokens, and unauthorized access attempts.
Can you give me an example of how to implement this?
Sure! You can create a middleware function that checks for these errors and sends appropriate responses to the client.
What response should I send for an invalid token?
For an invalid token, you can send a 401 Unauthorized status with a message indicating the token is invalid.
