Mobile application client built with React Native and Expo.

• Service Repository
• Project Repository

• React Native
• Expo
• TypeScript
• Firebase (for configuration)

npm install

Create a firebaseConfig.js file in the Client folder (or copy from config.example.ts):

export const firebaseConfig = {
  apiKey: "your-api-key",
  authDomain: "your-auth-domain",
  projectId: "your-project-id",
  storageBucket: "your-storage-bucket",
  messagingSenderId: "your-messaging-sender-id",
  appId: "your-app-id"
};

Ask your team lead for the actual Firebase credentials.

Important: You need to update the API URL to point to your local machine's IP address.

1. Find your computer's IP address:

   • Windows: Run ipconfig in terminal, look for "IPv4 Address"
   • Mac/Linux: Run ifconfig, look for your network interface

2. Edit Client/config/api.ts:

const DEFAULT_BASE = __DEV__
  ? (isWeb ? 'http://localhost:4000' : 'http://YOUR_IP_ADDRESS:4000')  // Replace with your IP
  : 'https://your-production-api.com';

Example: 'http://192.168.1.100:4000'

Before starting the client, make sure the backend service is running:

cd ../Service
npm run dev

npx expo start

• iOS Simulator: Press i
• Android Emulator: Press a
• Web: Press w
• Physical Device: Scan QR code with Expo Go app

• Your phone/emulator must be on the same WiFi network as your computer running the service
• Each team member runs their own backend server locally - you don't need to connect to each other's servers
• All team members connect to the same Azure database (shared data)
• If using a physical device, make sure your firewall allows connections on port 4000
• If the API isn't connecting, double-check your IP address in config/api.ts

The app uses different API URLs based on the platform:

• Web: Uses http://localhost:4000
• Mobile: Uses your computer's IP address (e.g., http://192.168.1.100:4000)

• Check that the Service is running (npm run dev in Service folder)
• Verify your IP address in config/api.ts matches your current IP
• Make sure your phone and computer are on the same WiFi

• Try restarting the Expo dev server
• Clear Expo cache: npx expo start -c

• Make sure firebaseConfig.js exists and has valid credentials
• Ask team lead for the Firebase configuration if you don't have it
