What are the best practices for using async middleware in web applications?

When using async middleware, it's important to ensure proper error handling, avoid blocking the event loop, and manage resource cleanup.

Can you explain how to handle errors in async middleware?

Certainly! You can use try-catch blocks within your async functions to catch errors and pass them to the next middleware using next(err).

What should I do to avoid blocking the event loop?

To avoid blocking the event loop, make sure to use non-blocking I/O operations and avoid long-running synchronous code.

Are there any libraries that can help with async middleware?

Yes, libraries like Express.js support async middleware natively, and you can also use async/await syntax for cleaner code.
