2. Backend Setup

1. Navigate to the backend directory:

cd backend

2. Install dependencies:

npm install

3. Create a .env file in the backend directory:

PORT=3000
NODE_ENV=development

# Google Maps API Key (Replace with your actual API key)
GOOGLE_MAPS_API_KEY=Your_API_KEY_HERE
GOOGLE_SPEECH_API_KEY=Your_API_KEY_HERE
PORT=3000
NODE_ENV=development

# Database Configuration (if needed later)
# DATABASE_URL=your_database_url

# JWT Secret (if needed for authentication)
JWT_SECRET=YOURSECRETKEYHERE

# Other Configuration
CORS_ORIGIN=http://localhost:19000

4. Start the backend server:

npm run dev

3. Frontend Setup

1. Navigate to the frontend directory:

cd frontend/NavApp

2. Install dependencies:

npm install

3. Create a config.secret.ts file in the frontend/NavApp directory:

export const GOOGLE_MAPS_API_KEY = 'your_google_maps_api_key';
export const API_URL = 'http://your_pc_ipaddress:3000';

4. Update the Google Maps API key in app.json:

{
  "expo": {
    "ios": {
      "config": {
        "googleMapsApiKey": "your_google_maps_api_key"
      }
    },
    "android": {
      "config": {
        "googleMaps": {
          "apiKey": "your_google_maps_api_key"
        }
      }
    }
  }
}

4. Environment Variables

Create a .env file in the root directory /NavApp:

GOOGLE_MAPS_API_KEY=YOURAPIKEY
API_URL=http://your_pc_ipaddress:3000

5. Configure API Endpoints:
   • Update the following files with your PC's IP address:
     • frontend/NavApp/app/admin/users.tsx (line 21)
     • frontend/NavApp/app/admin/incidents/[id].tsx (line 34)
     • frontend/NavApp/app/admin/incidents.tsx (line 24)
   • Replace http://your_pc_ipaddress:3000 with your actual IP address
   • Example: If your PC's IP is 192.168.1.100, use http://192.168.1.100:3000
   • Make sure your backend server is running on this IP address
   • Ensure your PC and mobile device are on the same network

5. Start the frontend development server:
```bash
npm expo start --tunnel

4. Environment Variables

Create a .env file in the root directory:

GOOGLE_MAPS_API_KEY=your_google_maps_api_key
API_URL=http://your_pc_ipaddress:3000

Important: Replace your_pc_ipaddress with your actual IP address in all configuration files. You can find your IP address by:

• Windows: Run ipconfig in Command Prompt
• macOS/Linux: Run ifconfig or ip addr in Terminal
• Make sure to use the IP address of your computer on the local network
