Koa

What is Koa?

An expressive middleware for Node.js, Koa utilizes generators via the co library to enhance the process of creating web applications and APIs. Koa's middleware flow operates in a stack-like manner, enabling developers to perform actions downstream and subsequently filter and manipulate the response upstream. The implementation of generators in Koa significantly improves the readability and robustness of the application, providing a more enjoyable development experience
