## Overview

This is a React chat application backed by a Django REST API, despite the README’s Spring Boot description. The main workflow is signup/login, room discovery and joining, then message exchange with presence and read/viewer information; users can also manage profiles and rooms. The frontend excerpts show the API calls and the backend excerpts show corresponding view behavior, but several modules are only represented by their paths, so uncertain internal wiring is omitted.

Main entry points: [`sic_back_django/sic_back_django/chat/views.py`](https://github.com/webnoureddine/chatappdj/blob/main/sic_back_django/sic_back_django/chat/views.py) (REST endpoints), [`sic_front/chatterbox-tailwind/src/component/api.js`](https://github.com/webnoureddine/chatappdj/blob/main/sic_front/chatterbox-tailwind/src/component/api.js) (HTTP API client), [`sic_front/chatterbox-tailwind/src/App.js`](https://github.com/webnoureddine/chatappdj/blob/main/sic_front/chatterbox-tailwind/src/App.js) (Routing and session), [`sic_front/chatterbox-tailwind/src/component/ChatRoom.js`](https://github.com/webnoureddine/chatappdj/blob/main/sic_front/chatterbox-tailwind/src/component/ChatRoom.js) (Chat interaction)
