🔌 API Reference

Geolocation API Integration

The application integrates with the following browser APIs:

Navigator.geolocation

// Get current position
navigator.geolocation.getCurrentPosition(
  (position) => {
    const { latitude, longitude, accuracy } = position.coords;
    // Handle successful location acquisition
  },
  (error) => {
    // Handle location error
  },
  {
    enableHighAccuracy: true,
    timeout: 10000,
    maximumAge: 300000
  }
);

// Watch position for continuous updates
const watchId = navigator.geolocation.watchPosition(
  (position) => {
    // Handle position updates
  },
  (error) => {
    // Handle watch error
  }
);

// Stop watching
navigator.geolocation.clearWatch(watchId);

Nominatim API (OpenStreetMap)

// Reverse geocoding request
const response = await fetch(
  `https://nominatim.openstreetmap.org/reverse?format=json&lat=${latitude}&lon=${longitude}&zoom=18&addressdetails=1`
);
const data = await response.json();

Custom Hooks

useGeolocation

const {
  latitude,
  longitude,
  accuracy,
  loading,
  error,
  supported,
  getPosition,
  startWatching,
  stopWatching
} = useGeolocation();

useReverseGeocode

const { address, loading, getAddress } = useReverseGeocode();

🚀 Deployment

Vercel (Recommended)

1. Connect your GitHub repository to Vercel
2. Configure build settings:
   • Build Command: npm run build
   • Output Directory: dist
   • Install Command: npm install
3. Add environment variables if needed
4. Deploy automatically on push

Netlify

1. Connect repository to Netlify
2. Set build command: npm run build
3. Set publish directory: dist
4. Configure redirects for SPA routing

Manual Deployment

# Build the application
npm run build

# Deploy the dist/ folder to your web server

🔒 Privacy & Security

Data Handling

• No Data Storage: Location data is never stored on servers
• Client-Side Processing: All location processing happens in the browser
• User Consent: Location access requires explicit user permission
• HTTPS Required: Geolocation API requires secure context

Security Considerations

• Content Security Policy: Implemented to prevent XSS attacks
• Secure Headers: Appropriate security headers configured
• API Rate Limiting: Respectful usage of external geocoding services
