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 powerful web applications with less boilerplate code and more flexibility. It also provides a robust set of features such as content negotiation, routing, and response handling.
Compared to Express, Koa offers a more modular and cleaner code structure, making it easier to manage complex applications. Koa is actively maintained and continues to evolve, making it a popular choice for developers seeking a modern and efficient web framework.
