Metro Times

Real-time Prague metro departure boards for your nearest stops. Two apps share the same Golemio API integration:

• mobile/ — Expo / React Native app (primary, targets iOS home-screen install).
• web/ — Next.js 14 App Router app (original implementation, kept as a fallback / reference).

Both apply the same data flow: browser geolocation → 5 nearest stops from a static list → Golemio departureboards API polled every 2s via React Query.

Mobile (mobile/)

cd mobile
pnpm install
pnpm exec expo start

See mobile/README.md for the Expo-generated notes, and PLAN.md for the standalone-iOS-install flow (free Apple ID signing path).

Web (web/)

cd web
pnpm install
pnpm dev      # http://localhost:3000
pnpm build    # production build
pnpm lint     # next lint

Environment

Both apps need a Golemio API token in their own .env.local:

• web/.env.local — NEXT_PUBLIC_API_KEY=...
• mobile/.env.local — EXPO_PUBLIC_API_KEY=...

Because these are NEXT_PUBLIC_* / EXPO_PUBLIC_*, the token ships to the client — treat any rotation as public.

Playground

Playground in ./playground is just for testing - no structure, nothing interesting.
