A Comparative Study of Express.js and Koa.js

Hello, there! Middleware has become an integral part of server-side programming, because they are functions that operate on request and response objects, often altering, adding information, or handling the flow of these objects in some way before they reach their final route handler. Given the utility of these middleware, server-side technologies often provide frameworks that facilitate the development and use of such tools. This article delves into two such popular frameworks in the Node.js ecosystem: Express.js and Koa.js. <h2>Express.js and Koa.js</h2> Express.js, recognized as the de facto standard server framework for Node.js, has been instrumental in shaping the landscape of web development with its robust features, including a strong middleware system. Koa.js, on the other hand, a next-generation web framework for Node.js, has been developed by the team behind Express.js and aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. This framework does not bundle any middleware within its core, offering developers more control and freedom. <a href="https://medium.com/bitsrc/implementing-middleware-in-node-js-a-comparative-study-of-express-js-and-koa-js-a93f2ebd867c">Read More</a>
