Introduction
Developing a real-time chat application involves more than just basic messaging. In this tutorial, weβll explore how to build a fully responsive chat app from scratch using modern web technologies. This app includes essential features like group chats, file uploads, and real-time communication, making it an excellent project for anyone interested in full-stack development.
Key Features of Our Chat Application
Hereβs a breakdown of the key features and technologies that power our chat app:
Frontend (React)
- UI Components: ShadCN for intuitive, modular components.
- Styling: Tailwind CSS ensures a modern, responsive design.
- Responsiveness: Adaptable for both mobile and desktop devices.
Backend (Node.js and Express)
- Data Storage: MongoDB, optimized for handling user data and messages.
- Authentication: JWT for secure, token-based authentication.
- Real-Time Communication: Socket.io for instant messaging functionality.
Additional Features
- File Handling: Multer is used to handle file uploads and storage.
- State Management: Zustand for managing user sessions and chat states.
- API Calls: Axios for efficient API communication.
Building the Frontend
In this section, guide your readers through setting up a React app and installing dependencies like ShadCN, Tailwind CSS, and Zustand.

That's an amazing project, you could have added Voice and Video Calls as well. That would have made the project a complete chat app. Love the UI.
Thanks for the input, I will take this into consideration for the next project.
Maybe you can use web assembly library with rust in your next project. So your react app will work much more faster than usual. Just consider this idea π
Using Next.js would be more better.
Noted.
