What are some popular async middleware libraries for Node.js?
Some popular async middleware libraries for Node.js include Express, Koa, and Hapi. They help manage asynchronous operations.
Can you explain how Koa differs from Express?
Koa is designed to be a smaller, more expressive, and more robust foundation for web applications and APIs. Unlike Express, Koa uses async/await for better error handling and cleaner code.
Are there any specific use cases where one is better than the other?
Yes, Koa is often preferred for modern applications that require more control over middleware, while Express is great for quick setups and has a larger ecosystem.
What about Hapi? How does it fit into the picture?
Hapi is known for its powerful plugin system and configuration-driven approach, making it suitable for large-scale applications with complex requirements.
