By the end, you'll see why Express has become the go‑to framework for building web servers with Node.js. Let's jump in. What is Express.js? Express.js is a minimal and flexible web application framework for Node.js. It provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love.…
