Koa vs Express: Which is better for Node.js?

What's the difference between Koa and Express?

Koa is a newer framework created by the same team behind Express. It uses async/await for better control over middleware, while Express uses a more traditional callback approach.

Which one is better for building APIs?

It depends on your needs. Koa offers more flexibility and modern features, making it great for new projects, while Express has a larger ecosystem and more middleware options.

Is Koa harder to learn than Express?

Koa can be a bit more challenging due to its use of async/await and less built-in functionality, but many find it more intuitive once they get used to it.

Can I use middleware in Koa like I do in Express?

Yes, Koa supports middleware, but the way you implement it is different. Koa's middleware is based on promises, allowing for more control over the flow.
