chat-server

A small asyncio TCP chat server. Multi-room, plaintext, with in-memory state and periodic JSON persistence.

Connect

1. Run nc <server-address> <port> (ask me for the address and port).
2. Enter the password when prompted (ask me if you know me).
3. Pick a username.
4. Start chatting.

Commands:

• /join <room> — switch rooms (default is lobby)
• /who — list users in your room
• /quit — disconnect

Windows users don't have nc by default — install ncat (choco install nmap) or run the same nc command from WSL.

Run locally

Requires Python 3.10+. No external dependencies.

CHAT_PASSWORD=hunter2 python3 chat_server.py

Then connect from another terminal:

nc 127.0.0.1 8888
