Project Description

In this project, we’ll build a real-time chat app using Socket.IO. The application will allow users to follow and chat with different users in real time.

Socket.IO can be used to build a variety of applications that require real-time communication capabilities, such as streaming applications, document collaboration, and instant messaging. We’ll use Socket.IO to send messages to other online users. We’ll also use the Express framework for Node.js to develop the back-end API to interact with MongoDB to fetch and store data. After setting up the backend, we’ll implement the front-end components and add the messaging functionality. The finalized product will fetch the data from MongoDB via the Node.js server and display it in the React functional components.

The components in the application are styled with pre-written CSS and code to provide an initial template for an image-sharing application.
