Real-Time Chat Server with WebSockets

Project roadmap

1. 01

   Set up the async WebSocket server

   ~1.5h

   Create a websockets server that accepts connections and echoes messages back to confirm the event loop works.

2. 02

   Implement room-based broadcasting

   ~2.5h

   Track connected clients per room and broadcast incoming messages to all clients in the same room.

3. 03

   Add join, leave, and history handling

   ~2h

   Support join/leave commands and store recent message history per room to send to newly joined clients.

4. 04

   Handle disconnects and errors gracefully

   ~1.5h

   Detect dropped connections, clean up client state, and prevent one client's error from crashing the server.

5. 05

   Build a minimal web client

   ~2h

   Write a small HTML/JS page that connects to the server so the chat can be tested in a browser.
