Introduction to the Course: WebSockets with Node.js

Welcome to the WebSockets with Node.js course! 🚀 In this journey, we will explore how to use WebSockets in combination with Node.js to create real-time web applications.

What are WebSockets?

WebSockets are an advanced technology that allows for a bidirectional connection between the client and the server. Unlike the HTTP protocol, which follows a request-response model, WebSockets enable continuous communication without the need for new requests. This is ideal for applications like real-time chats, online games, and real-time content updates.

Why use Node.js?

Node.js is perfect for working with WebSockets due to its asynchronous and event-driven nature. The combination of WebSockets and Node.js allows managing multiple connections efficiently, making your application truly scalable.
