## Overview

QuickChat is a one-to-one messaging application. A user authenticates, opens the directory, selects a person, loads chat history, and sends text or an image; the server persists messages and dispatches them to an online recipient, while tracking presence and seen state. The graph reflects documented profile and media features as well as sampled API, context, and socket wiring. Some UI and route internals are not sampled, so their detailed connections are omitted.

Main entry points: [`Server/controllers/messageController.js`](https://github.com/gaurav-patil-13/quick-chat/blob/main/Server/controllers/messageController.js) (Message operations), [`Client/context/ChatContext.jsx`](https://github.com/gaurav-patil-13/quick-chat/blob/main/Client/context/ChatContext.jsx) (Chat state), [`Server/server.js`](https://github.com/gaurav-patil-13/quick-chat/blob/main/Server/server.js) (Socket and presence), [`Client/src/App.jsx`](https://github.com/gaurav-patil-13/quick-chat/blob/main/Client/src/App.jsx) (App routing)
