Hey HN! I built this for my weekly poker games because I was tired of chip counting arguments.

  TECH STACK:
  • Pure vanilla JavaScript (no frameworks, ~25KB total)
  • PeerJS for P2P multiplayer (no backend needed)
  • WebRTC for device sync
  • Service worker PWA
  • Hosted on GitHub Pages

  WHY NO FRAMEWORK:
  Wanted to keep it dead simple and fast. No build step, no dependencies, just open the HTML file and it works.

  MULTIPLAYER ARCHITECTURE:
  The interesting part was implementing peer-to-peer state sync without a central server. One player hosts, generates a 6-char room code, others join directly via
  WebRTC. All game state syncs in real-time across devices with 50ms debouncing.

  CHALLENGES:
  • Handling disconnections gracefully
  • Keeping poker betting logic accurate (min raise rules, side pots)
  • Making WebRTC reliable across different networks
