Real-time Chat Server with Rooms

Project roadmap

1. 01

   Set up WebSocket connections

   ~1.5h

   Implement an HTTP upgrade handler and a client struct representing each WebSocket connection.

2. 02

   Build the hub pattern

   ~2.5h

   Implement a central hub managing rooms and broadcasting messages to clients via channels.

3. 03

   Support room join/leave

   ~2h

   Add commands for clients to join and leave rooms, maintaining per-room client lists.

4. 04

   Handle concurrent I/O safely

   ~2h

   Use dedicated read and write goroutines per connection to avoid concurrent access issues.

5. 05

   Buffer message history

   ~1.5h

   Keep a recent message buffer per room so newly joined clients see recent context.

6. 06

   Load test the server

   ~2h

   Simulate many concurrent clients to verify the server holds up under load.
