What are the differences between Express and Koa?
An example of an AI chatbot conversation about the differences between Express and Koa frameworks.
What are the main differences between Express and Koa?
Express is a minimal and flexible Node.js web application framework, while Koa is designed to be a smaller, more expressive, and more robust foundation for web applications and APIs.
Can you explain the middleware handling in both frameworks?
In Express, middleware functions are executed in the order they are defined, while Koa uses async functions and a more modern approach to handle middleware, allowing for better control over the flow.
Which one is better for building APIs?
It depends on your needs. Express is great for quick setups and has a large ecosystem, while Koa offers more control and is better suited for complex applications.
Are there any performance differences?
Koa generally has better performance due to its lightweight nature and async/await support, which can lead to more efficient handling of requests.
