Koa.js, or a lighter version of ExpressJS (from the same creators)

Koa.js is a modern framework for building web applications in Node.js. It was created by the team behind the popular Express.js framework, aiming to provide a simpler, more flexible, and efficient development experience. Koa is minimalist, meaning it does not come with many built-in features and allows developers to add only those necessary for their specific applications. This makes Koa suitable for both small and large projects, where ease of modification and control over functionality are essential. By utilizing asynchronous functions, Koa efficiently manages application scalability, which is crucial in today's world where applications must handle a high number of users. To get started with Koa, you just need to install it via npm and set up a basic application in just a few simple steps, making it accessible for developers of all skill levels.
