Real time chat application using Nodejs and Socket io …!

AS we all know that Node.js is an open-source and cross-platform JavaScript runtime environment.Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser.

A real-time chat application using Node.js and Socket.io allows users to communicate with each other instantly. Node.js is a server-side JavaScript runtime that enables developers to build scalable, high-performance applications, while Socket.io is a library that enables real-time, bi-directional communication between clients and servers.

To create a chat application, the first step is to set up a Node.js server using a web framework like Express.js. Then, Socket.io is used to establish a connection between the client and the server, allowing messages to be sent and received in real-time.

Messages are sent between clients using events, which can be customized to include data such as usernames, messages, and timestamps. The server can also emit events to all connected clients, such as when a new user joins the chat room.

The client-side of the application can be built using HTML, CSS, and JavaScript. Users can interact with the chat room through a simple interface that allows them to enter messages and view previous messages. The application can be further enhanced with additional features such as private messaging and user authentication.

Overall, a real-time chat application using Node.js and Socket.io provides a scalable, efficient, and customizable solution for real-time communication between users.

Socket.IO--à>It is javascript library in which two way communication between client and server.

ITS bidirectional and in this multiple user can connect and they can talk and collebrate

To install socket.ioà>npm I socket.io

By joining in the real time chat application user will get the notification and if they will remove from the chat then they will also get the notification ..

In the next slides there is a demo images an I will also show you live preview………!

To established the connection between client with server.. we have add one script

<script defer src="http://localhost:8000/socket.io/socket.io.js"></script>

In this project basically i create two types of server client server and Node server in which client server helps us to golive and nodeserver which will listen everything and takes and actions accordingly.

Node server which will handle socket io connections:
