Guess the country geography game with real-time multiplayer presence.

Stack

• Frontend — Next.js (apps/frontend-js)
• Backend — Go (apps/backend-go)
• Reverse proxy — Caddy (apps/reverse-proxy)
• Database — PostgreSQL

Running locally

Docker runs everything behind Caddy. For local development, the Go backend and frontend run outside Docker while postgres stays containerised.

# start postgres
docker compose up postgres -d

# backend
cd apps/backend-go && air

# frontend
cd apps/frontend-js && npm run dev

Required: .env.local

Create apps/frontend-js/.env.local:

NEXT_PUBLIC_WS_URL=ws://localhost:4000/ws

Without this, the WebSocket connects through the Next.js dev server which cannot proxy WebSocket connections. In Docker, Caddy handles the /ws route so this variable is not needed.
