Introduction
Express.js is a free and open-source back-end web framework for Node.js. Node.js is a runtime environment used to execute JavaScript code outside of a browser. It is used to produce dynamic web page content before sending it to the user's web browser.
One crucial point is that NodeJS isn't a framework, and it's not even a programing language. It aims at providing an event-driven, non-blocking (asynchronous) I/O and cross-platform runtime environment so that users can build highly scalable server-side applications using JavaScript.
In this article, we’ll be learning about express.js in detail. So, let’s get started!
Express as a Node.js Framework
Express is a small framework. It sits on top of Node.js as web server functionality to simplify its APIs and add more helpful new features.
With middleware and routing,
Express makes it easier to structure the functionality of our application. It allows us to provide useful utilities to the HTTP objects in Node.js. It makes it easier to render dynamic HTTP objects.
Express is a part of the MERN stack, a full-stack JavaScript solution used to build one of the fastest, robust, and maintainable production web applications.
