Setup & Installation

Prerequisites​

  • Node.js 18+
  • Use a Physical Device for testing Camera streams (Simulators struggle with WebRTC/video).
  • Install Expo Go app from App Store / Play Store.

Quickstart​

1. Install Dependencies​

cd apps/mobile
npm install

2. Configure Environment​

Create a .env file pointing to your backend (use your computer's local LAN IP, e.g. 192.168.1.50, not localhost, so the phone can reach it).

EXPO_PUBLIC_API_URL=http://192.168.1.50:3333
EXPO_PUBLIC_WS_URL=http://192.168.1.50:3333

3. Run the App​
