Node Socket.io Tutorial is the topic we will deep dive into today. We will build a simple chat app today. We will use Node.js for the backend platform and Socket.io for real-time two-way communication. Now, first, we need to create a package.json file to install our required dependencies.

Node Socket.io example

WebSocket is the internet protocol that allows for full-duplex communication between a server and clients.

This protocol goes beyond the typical HTTP request/response paradigm; with WebSockets, the server may send data to a client without the client initiating a request, thus allowing for some very interesting applications.

Most tutorials you’ll find on WebSockets have you build a chat app, and we will do the same here. We’ll be using the popular  Socket.IO Node.js server framework to accomplish this.

Install the required dev dependencies for our project.
