Koa is a lightweight and expressive Node.js web framework designed by the creators of Express. It uses modern JavaScript features like async/await to streamline middleware composition and improve error handling. Koa's minimalistic design allows developers to build efficient and scalable web applications with a focus on simplicity and modularity. It provides a robust set of methods for handling requests, responses, and middleware functions.
Compared to Express, Koa offers a more elegant and concise syntax, making it easier to write clean and maintainable code. Koa is actively maintained and continues to evolve, offering a modern alternative for building web servers and APIs in Node.js.
