How can I debug middleware issues in my Express app?

To debug middleware issues in Express, you can start by adding logging statements in your middleware functions to track the flow of requests.

What kind of logging should I add?

You can log the request method, URL, and any relevant headers or body data. This will help you see if the middleware is being executed as expected.

What if the middleware is not being called at all?

If the middleware isn't being called, check the order in which you've defined your middleware in the app. Middleware should be defined before your route handlers.

Are there any tools that can help with debugging?

Yes, you can use tools like Postman to test your endpoints and see the responses, or use Node.js debugging tools like the built-in debugger or Visual Studio Code.
