How can I debug my Express API effectively?

You can use tools like Postman for testing endpoints, and add logging to your routes to track requests.

What logging libraries do you recommend for Express?

I recommend using 'morgan' for HTTP request logging and 'winston' for general logging.

How can I handle errors in my Express app?

You can use middleware to catch errors and send appropriate responses. Make sure to define an error-handling middleware.

Can you show me an example of error-handling middleware?

Sure! Here's a simple example:

app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).send('Something broke!');
});
