What are the best practices for implementing asynchronous middleware?

When implementing asynchronous middleware, consider using proper error handling, ensuring non-blocking operations, and maintaining a clear flow of data.

Can you explain why non-blocking operations are important?

Non-blocking operations allow your application to handle multiple requests simultaneously, improving performance and responsiveness.

What are some common pitfalls to avoid?

Common pitfalls include neglecting error handling, creating race conditions, and failing to manage resource usage effectively.

How can I test my asynchronous middleware?

You can use tools like Mocha or Jest for unit testing, and ensure to simulate asynchronous behavior in your tests.
