What are some advanced techniques for routing in Express?

Can you explain how to use route parameters?

Sure! Route parameters are named URL segments that can be used to capture values from the URL. For example, in the route '/users/:id', ':id' is a route parameter that captures the user ID.

How do I handle errors in my routes?

You can handle errors in Express routes by using middleware. Define an error-handling middleware function that takes four arguments: err, req, res, and next. This function can then send a response based on the error.

What about using middleware for authentication?

Using middleware for authentication is a common practice. You can create a middleware function that checks if a user is authenticated before allowing access to certain routes.
