What are some common libraries that can help with error handling in Express?

Several libraries can simplify error handling in Express: 1) `http-errors`: Creates standard HTTP error objects. 2) `express-async-errors`: Automatically handles errors in async/await functions. 3) `winston` or `morgan`: For logging errors. 4) `helmet`: Helps secure your app and can include error handling related security features. 5) `joi`: For validating request data and generating appropriate error responses.
