In this tutorial, we will create a real-time chat application using Node.js and WebSockets. Real-time communication is a crucial aspect of modern web applications, allowing users to interact with each other instantaneously. By leveraging WebSockets, we can establish a persistent connection between the client and server, enabling seamless data exchange.
WebSockets provide a full-duplex communication channel over a single TCP connection, allowing both the client and server to send messages at any time. Unlike HTTP, WebSockets maintain a persistent connection, making them ideal for applications requiring real-time updates, such as chat apps, online gaming, and live notifications.
