How to Run (Docker)

docker compose up --build

Connecting from a phone (Expo Go)

1. Put your phone and laptop on the same Wi‑Fi.
2. Find your laptop's LAN IP (Mac: ipconfig getifaddr en0, Linux: hostname -I | awk '{print $1}', Windows: ipconfig).
3. Set EXPO_PUBLIC_API_URL=http://<your-ip>:8080/api in your .env file (used by docker compose).
4. Restart the mobile container so Expo picks up the new URL: docker compose up -d --build mobile-app.
5. Watch the Metro logs for [API] Using base URL: to confirm the app is talking to the right backend.
