Introduction

Developing a real-time chat application involves more than just basic messaging. In this tutorial, we’ll 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

Here’s a breakdown of the key features and technologies that power our chat app:

Frontend (React)
