What are the best practices for using middleware in web development?

Some best practices include keeping middleware functions small, using them for specific tasks, and ensuring they are reusable.

Can you give me an example of a middleware function?

Sure! A common example is an authentication middleware that checks if a user is logged in before allowing access to certain routes.

How do I handle errors in middleware?

You can handle errors by using a centralized error-handling middleware that catches errors from other middleware and routes.
