Koa: Detailed Overview & Metrics
Koa is a minimal and lightweight web framework for Node.js, designed for building high-performance HTTP servers and web applications. It uses async functions, generators, and the latest JavaScript language features to make writing middleware easier and more enjoyable. Koa focuses on being unopinionated and modular, and provides a robust set of features for building web applications.
Compared to other web frameworks such as Express, Koa has a smaller codebase and is more flexible, allowing developers to choose the middleware they need. It uses a middleware stack instead of middleware chains, meaning you can compose middleware differently than with Express. Additionally, Koa provides better error handling and simpler testing with its APIs.
