## Overview

This is a React chat client whose main workflow is signing in, opening a chat, composing a message, and sending it in real time or queuing it offline for later delivery. The repository separates routed screens and chat UI from message/state coordination, API and socket integrations, and local persistence. The README documents queue behavior and major chat capabilities; sampled source confirms routing, IndexedDB hydration, API request handling, and selected UI features. Unverified connections between unsampled modules are omitted.

Main entry points: [`src/App.tsx`](https://github.com/springboot20/chat-application/blob/main/src/App.tsx) (App routes), [`src/hooks/useMessageQueue.ts`](https://github.com/springboot20/chat-application/blob/main/src/hooks/useMessageQueue.ts) (Queue processor), [`src/layouts/ChatLayout.tsx`](https://github.com/springboot20/chat-application/blob/main/src/layouts/ChatLayout.tsx) (Chat layout), [`src/pages/Chat/ChatRoom.tsx`](https://github.com/springboot20/chat-application/blob/main/src/pages/Chat/ChatRoom.tsx) (Chat room)
