How to Build a Realtime Chat App with Node.js
In this tutorial, we are going to build a basic chat application with Node.js. Before we get started, I assume that you have little bit knowledge of JavaScript and Node.js.
Here, we will be using an awesome tool called Socket.io. If you don’t know what that is, basically it’s a JavaScript library that allows you to handle realtime data on front-end and back-end side. We also going to use Express which is by far the most popular Node.js framework for building web-based applications.
