How can I implement error handling in my routing system?

You can implement error handling in your routing system by using middleware to catch errors and respond appropriately.

What types of errors should I handle?

You should handle 404 errors for not found routes, 500 errors for server issues, and validation errors for user input.

Can you give me an example of middleware for error handling?

Sure! Here's a simple example:

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

How can I log errors for later analysis?

You can use logging libraries like Winston or Morgan to log errors to a file or external service for later analysis.
