#### iOS Setup

1. Add the following permission to your ios/YourApp/Info.plist:

`xml
NSLocationWhenInUseUsageDescription
This app needs access to your location to provide location-based services.
`

For background location (optional):

`xml
NSLocationAlwaysAndWhenInUseUsageDescription
This app needs access to your location in the background.
NSLocationAlwaysUsageDescription
This app needs access to your location.
`

2. Run pod install:

`bash
cd ios && pod install && cd ..
`

#### Android Setup

1. Add permissions to your android/app/src/main/AndroidManifest.xml:

`xml







`

2. For Android 10+ (API level 29+), request runtime permissions in your app before using location services.

📖 Usage

$3

Wrap your app (or specific components) with NewLocationProvider:

`tsx
import NewLocationProvider from '@eyuphantilki/location-listener';

function App() {
return (



);
}

export default App;
`

$3

Use the useLocation hook to access the current location and control the listener:

`tsx
import { useLocation } from '@eyuphantilki/location-listener';
import { View, Text, Button } from 'react-native';

function MyComponent() {
const { location, startListening } = useLocation();

if (!location) {
return Waiting for location...;
}

return (

Latitude: {location.lat}
Longitude: {location.long}


);
}
`

$3

Pass an onLocation callback to NewLocationProvider to receive location updates directly. This is perfect for logging, analytics, or sending data to your backend:

`tsx
import NewLocationProvider, { LocationType } from '@eyuphantilki/location-listener';

function App() {
const handleLocationUpdate = (loc: LocationType) => {
console.log('New location:', loc.lat, loc.long);
// Send to your API, log to analytics, etc.
logToBackend(loc);
};

return (



);
}
`

$3

`tsx
import React, { useCallback } from 'react';
import NewLocationProvider, { LocationType } from '@eyuphantilki/location-listener';
import { NavigationContainer } from '@react-navigation/native';

function App() {
const logLocationToServer = useCallback(async (loc: LocationType) => {
try {
await fetch('https://your-api.com/log-location', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_TOKEN'
},
body: JSON.stringify({
latitude: loc.lat,
longitude: loc.long,
timestamp: new Date().toISOString(),
accuracy: 'medium'
})
});
} catch (error) {
console.error('Failed to log location:', error);
// Handle error (e.g., queue for retry)
}
}, []);

return (





);
}

export default App;
`

`tsx
import React, { useCallback, useState } from 'react';
import NewLocationProvider, { useLocation, LocationType } from '@eyuphantilki/location-listener';
import { View, Text, Button, StyleSheet } from 'react-native';

function LocationDisplay() {
const { location, startListening } = useLocation();
const [lastUpdate, setLastUpdate] = useState(null);

if (!location) {
return (

🔍 Acquiring location...
Please enable location services

);
}

return (

📍 Current Location
Latitude: {location.lat.toFixed(6)}
Longitude: {location.long.toFixed(6)}
{lastUpdate && (

Last update: {lastUpdate.toLocaleTimeString()}

)}


);
}

function App() {
const handleLocationUpdate = useCallback((loc: LocationType) => {
console.log('📍 Location updated:', loc);
setLastUpdate(new Date());

// Your custom logic here
// - Send to analytics
// - Update map
// - Trigger geofencing checks
}, []);

return (



);
}

🔧 API Reference

$3

The main provider component that manages location tracking lifecycle.

Props:

| Prop | Type | Required | Default | Description |
|------|------|----------|---------|-------------|
| children | React.ReactNode | ✅ Yes | - | Your app components that will have access to location context |
| onLocation | (loc: LocationType) => void | ❌ No | undefined | Callback function invoked on every location update. Receives the new location object. |

Example:

`tsx
console.log('Location:', loc)}>
{children}

`

Behavior:
- Automatically requests location permissions on mount
- Starts location tracking immediately after permission is granted
- Cleans up all watchers and timers on unmount
- Manages internal retry logic for failed location requests

$3

Access location state and controls from any component within the provider.

Returns:

`typescript
{
location: LocationType | null; // Current location or null if not yet available
startListening: () => void; // Function to manually restart location tracking
}
`

Example:

`tsx
const { location, startListening } = useLocation();

if (location) {
console.log(Current position: ${location.lat}, ${location.long});
}

// Manually restart location tracking
startListening();
`

Notes:
- location will be null until the first successful location fetch
- location will be set to null if permissions are denied
- startListening() can be called to manually restart the entire location acquisition flow
- This hook must be used within a NewLocationProvider component

$3

The location object type returned by the hook and passed to callbacks.

`typescript
type LocationType = {
lat: number; // Latitude in decimal degrees
long: number; // Longitude in decimal degrees
};
`

Example:

`tsx
const location: LocationType = {
lat: 37.7749,
long: -122.4194
};
`

$3

The underlying React Context. Exported for advanced use cases.

`typescript
const LocationListener = createContext({
location: null,
startListening: () => {}
});
`

Interface:

`typescript
interface LocationContextType {
location: LocationType | null;
startListening: () => void;
}
`

⚙️ How It Works

$3

The package follows a sophisticated initialization sequence to ensure reliable location acquisition:

1. Mount & Permission Request
- On component mount, automatically calls Geolocation.requestAuthorization()
- Handles both success and error callbacks

2. Fast Location Fetch
- Immediately attempts to get current position with getCurrentPosition()
- Uses optimized settings for quick response (20s timeout, 10s maximum age)

3. Intelligent Retry Logic
- If location fetch fails, implements exponential backoff
- Retries up to 5 times with increasing delays
- Delay formula: Math.min(2000 * Math.pow(1.5, attempt), 30000)

4. Continuous Watching
- After successful initial location, switches to watchPosition()
- Provides real-time location updates as user moves
- Updates every 5 meters or 10 seconds (whichever comes first)

5. Error Recovery
- If watcher encounters errors, automatically restarts after 5 seconds
- Checks isActiveRef to prevent unnecessary operations if component unmounted

$3

The exponential backoff strategy ensures we don't hammer the GPS service while still being responsive:

| Attempt | Delay | Cumulative Time |
|---------|-------|-----------------|
| 1 | 2 seconds | 2s |
| 2 | 3 seconds (2 × 1.5) | 5s |
| 3 | 4.5 seconds (3 × 1.5) | 9.5s |
| 4 | 6.75 seconds (4.5 × 1.5) | 16.25s |
| 5 | 10.125 seconds (6.75 × 1.5) | 26.375s |
| Fallback | Switch to watchPosition() | - |

Why this approach?
- Fast initial attempts for responsive UX
- Progressive delays to avoid battery drain
- Fallback to continuous watching as last resort
- Maximum delay capped at 30 seconds

$3

#### getCurrentPosition Configuration:
`typescript
{
enableHighAccuracy: false, // Uses network/WiFi for faster, battery-friendly results
timeout: 20000, // 20 second timeout per request
maximumAge: 10000 // Accept cached location up to 10 seconds old
}
`

Why these settings?
- enableHighAccuracy: false prioritizes speed and battery over precision
- 20s timeout balances responsiveness with giving GPS enough time
- 10s maximum age allows using recent cached positions

#### watchPosition Configuration:
`typescript
{
enableHighAccuracy: false, // Battery-friendly continuous tracking
distanceFilter: 5, // Only update if user moves 5+ meters
interval: 10000, // Check location every 10 seconds
fastestInterval: 5000, // Minimum 5 seconds between updates
timeout: 20000, // 20 second timeout per update
maximumAge: 5000 // Accept cached location up to 5 seconds old
}
`

Why these settings?
- distanceFilter: 5 prevents excessive updates when stationary
- interval: 10000 provides good update frequency without battery drain
- fastestInterval: 5000 prevents update flooding during fast movement
- Shorter maximumAge for watching ensures fresher data

$3

The package uses React refs for internal state to avoid unnecessary re-renders:

`typescript
const watchIdRef = useRef(null); // Current watch subscription ID
const retryTimerRef = useRef | null>(null); // Pending retry timer
const retryAttemptRef = useRef(0); // Current retry attempt count
const isActiveRef = useRef(false); // Whether tracking is active
`

Benefits:
- No re-renders from internal state changes
- Proper cleanup of timers and subscriptions
- Thread-safe state management

$3

The package implements comprehensive error handling:

| Error Type | Handler Behavior | Recovery Action |
|------------|------------------|-----------------|
| Permission Denied | Sets location to null, logs error | Stops tracking, waits for manual restart |
| Location Timeout | Logs error, increments retry counter | Retries with exponential backoff |
| Watcher Error | Logs error, clears current watch | Waits 5s, then restarts watch |
| Network Error | Handled by geolocation API | Uses cached location if within maximumAge |
| Component Unmount | Sets isActiveRef to false | Cancels all pending operations |

Console Logging:
- 'Geolocation permission granted' - Permission successfully obtained
- 'Geolocation permission denied' - User denied permission
- 'Location error:' - Error during getCurrentPosition
- 'Watcher error:' - Error during continuous watching

$3

On component unmount, the package performs thorough cleanup:

`typescript
useEffect(() => {
// ... initialization code

return () => {
isActiveRef.current = false; // Stop all operations
clearRetry(); // Cancel pending retry timers
clearWatch(); // Unsubscribe from location updates
};
}, []);
`

What gets cleaned up:
1. All watchPosition subscriptions via Geolocation.clearWatch()
2. All pending setTimeout retry timers
3. Active state flag to prevent zombie operations
4. No memory leaks, even with rapid mount/unmount cycles

💡 Best Practices

$3

Place the provider at your app's root to make location available globally:

`tsx
// App.tsx
import NewLocationProvider from '@eyuphantilki/location-listener';
import { NavigationContainer } from '@react-navigation/native';

export default function App() {
return (





);
}
`

$3

Never assume location is available immediately:

`tsx
const { location } = useLocation();

// ❌ Bad - Can crash
const distance = calculateDistance(location.lat, location.long);

// ✅ Good - Safe
if (!location) {
return ;
}
const distance = calculateDistance(location.lat, location.long);
`

$3

Use useCallback to prevent unnecessary re-renders:

`tsx
import { useCallback } from 'react';

const handleLocation = useCallback((loc: LocationType) => {
// Your logic here
sendToAnalytics(loc);
updateMap(loc);
}, []); // Empty deps = stable reference


`

$3

Wrap location-dependent components in error boundaries:

`tsx
import { ErrorBoundary } from 'react-error-boundary';

function LocationErrorFallback({ error }) {
return (

Failed to get location: {error.message}
window.location.reload()} />

);
}






`

$3

The default settings are battery-optimized, but you can further optimize:

`tsx
// ✅ Good - Use the package as-is for balanced performance


// ❌ Avoid - Don't modify internal settings unless necessary
// The package is already optimized for:
// - 5-meter distance filter (no updates when stationary)
// - 10-second intervals (reasonable update frequency)
// - Low accuracy mode (uses WiFi/cellular over GPS)
`

Additional battery tips:
- Stop tracking when app goes to background
- Increase distanceFilter for less frequent updates
- Use startListening() sparingly (it restarts the entire flow)

$3

Provide fallback UI when permissions are denied:

`tsx
function LocationAwareComponent() {
const { location } = useLocation();
const [permissionDenied, setPermissionDenied] = useState(false);

useEffect(() => {
const timer = setTimeout(() => {
if (!location) setPermissionDenied(true);
}, 5000); // Assume denied after 5 seconds

return () => clearTimeout(timer);
}, [location]);

if (permissionDenied) {
return (

Location permission required
title="Open Settings"
onPress={() => Linking.openSettings()}
/>

);
}

return ;
}
`

$3

Don't spam your backend with every location update:

`tsx
import { useRef } from 'react';

const lastLoggedRef = useRef(0);
const MIN_LOG_INTERVAL = 30000; // 30 seconds

const handleLocation = useCallback((loc: LocationType) => {
const now = Date.now();
if (now - lastLoggedRef.current > MIN_LOG_INTERVAL) {
sendToBackend(loc);
lastLoggedRef.current = now;
}
}, []);
`

$3

Leverage the exported types for type safety:

`tsx
import NewLocationProvider, {
LocationType,
useLocation
} from '@eyuphantilki/location-listener';

// Type your callbacks
const handleLocation = (loc: LocationType): void => {
console.log(loc);
};

// Type your state
const [locations, setLocations] = useState([]);

// Type your refs
const lastLocationRef = useRef(null);
`

🐛 Troubleshooting

$3

Possible causes:
- ❌ Location permissions denied by user
- ❌ Location services disabled in device settings
- ❌ Using iOS simulator without location mock
- ❌ Android emulator without GPS mock
- ❌ App in background without background permission

Solutions:

1. Check permissions:
`tsx
import { PermissionsAndroid, Platform } from 'react-native';

const checkPermission = async () => {
if (Platform.OS === 'android') {
const granted = await PermissionsAndroid.check(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION
);
console.log('Permission granted:', granted);
}
};
`

2. Verify Info.plist (iOS):
`bash

Check if permission keys exist

cat ios/YourApp/Info.plist | grep -A1 "NSLocation"
`

3. Enable location in simulator:
- iOS Simulator: Features → Location → Custom Location
- Android Emulator: Extended controls (⋯) → Location

4. Check device settings:
- iOS: Settings → Privacy → Location Services
- Android: Settings → Location → App permissions

$3

Possible causes:
- ❌ Poor GPS signal (indoors, urban canyons)
- ❌ Device in airplane mode
- ❌ Location services in battery saver mode
- ❌ Too many apps using location simultaneously

Solutions:

1. Increase timeout values (fork and modify):
`typescript
// In index.tsx
timeout: 30000, // Increase from 20000 to 30000
maximumAge: 15000 // Increase from 10000 to 15000
`

2. Enable high accuracy mode (trades battery for accuracy):
`typescript
enableHighAccuracy: true // Change from false
`

3. Check signal strength:
`tsx
// Log accuracy from position object
Geolocation.getCurrentPosition(
position => {
console.log('Accuracy:', position.coords.accuracy, 'meters');
}
);
`

$3

Possible causes:
- ❌ enableHighAccuracy set to true
- ❌ Very low distanceFilter causing constant updates
- ❌ Very low interval causing frequent checks
- ❌ Multiple location providers active

Solutions:

1. Use default settings (already optimized):
`tsx
// Default settings are battery-friendly:
enableHighAccuracy: false // Uses WiFi/cell instead of GPS
distanceFilter: 5 // Only updates after 5m movement
interval: 10000 // 10 second check interval
`

2. Stop tracking when not needed:
`tsx
import { AppState } from 'react-native';

useEffect(() => {
const subscription = AppState.addEventListener('change', nextAppState => {
if (nextAppState === 'background') {
// Optionally stop tracking when app goes to background
isActiveRef.current = false;
clearWatch();
}
});

return () => subscription.remove();
}, []);
`

3. Implement smart update logic:
`tsx
const handleLocation = useCallback((loc: LocationType) => {
// Only process if location changed significantly
if (lastLocationRef.current) {
const distance = calculateDistance(lastLocationRef.current, loc);
if (distance < 10) return; // Ignore < 10m changes
}

lastLocationRef.current = loc;
processLocation(loc);
}, []);
`

$3

Error: Unable to resolve module @eyuphantilki/location-listener

Solutions:

1. Clear Metro cache:
`bash
npx react-native start --reset-cache
`

2. Reinstall dependencies:
`bash
rm -rf node_modules
npm install

or

yarn install
`

3. Clear watchman (if installed):
`bash
watchman watch-del-all
`

4. Verify installation:
`bash
npm list @eyuphantilki/location-listener
`

$3

Error: Cannot find module '@eyuphantilki/location-listener' or its corresponding type declarations

Solutions:

1. Restart TypeScript server in VS Code:
- Cmd/Ctrl + Shift + P → "TypeScript: Restart TS Server"

2. Check tsconfig.json:
`json
{
"compilerOptions": {
"moduleResolution": "node",
"esModuleInterop": true,
"allowSyntheticDefaultImports": true
}
}
`

3. Verify types field in package.json:
`bash
npm view @eyuphantilki/location-listener types

Should return: index.tsx

`

$3

Permissions not being requested on Android:

1. Check targetSdkVersion in android/app/build.gradle:
`gradle
android {
defaultConfig {
targetSdkVersion 31 // Should be 23+
}
}
`

2. Request runtime permissions (Android 6.0+):
`tsx
import { PermissionsAndroid, Platform } from 'react-native';

const requestLocationPermission = async () => {
if (Platform.OS === 'android') {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
{
title: 'Location Permission',
message: 'This app needs access to your location',
buttonNeutral: 'Ask Me Later',
buttonNegative: 'Cancel',
buttonPositive: 'OK',
}
);
return granted === PermissionsAndroid.RESULTS.GRANTED;
}
return true;
};
`

$3

Location not working on iOS:

1. Rebuild after Info.plist changes:
`bash
cd ios
pod install
cd ..
npx react-native run-ios
`

2. Check app capabilities in Xcode:
- Open ios/YourApp.xcworkspace in Xcode
- Select target → Signing & Capabilities
- Verify "Location" capability if using background location

3. Reset location permissions in simulator:
- Simulator → Features → Location → Don't Simulate Location
- Then: Features → Location → Custom Location

🔒 Privacy & Security

$3

1. Be transparent about location usage in your privacy policy
2. Request permissions with clear explanation
3. Minimize data collection - only log what you need
4. Encrypt location data when sending to backend
5. Implement data retention policies

$3

`tsx
import { useCallback } from 'react';
import CryptoJS from 'crypto-js';

const ENCRYPTION_KEY = 'your-secret-key';

const handleLocation = useCallback(async (loc: LocationType) => {
// Encrypt location data
const encrypted = CryptoJS.AES.encrypt(
JSON.stringify(loc),
ENCRYPTION_KEY
).toString();

// Send encrypted data
await fetch('https://api.example.com/location', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': Bearer ${userToken}
},
body: JSON.stringify({ data: encrypted })
});
}, []);
`

🧪 Testing

$3

`tsx
// __mocks__/@eyuphantilki/location-listener.tsx
import React from 'react';

export const mockLocation = { lat: 37.7749, long: -122.4194 };

export const useLocation = jest.fn(() => ({
location: mockLocation,
startListening: jest.fn()
}));

export default function NewLocationProvider({ children }: any) {

test('displays location when available', () => {
(useLocation as jest.Mock).mockReturnValue({
location: { lat: 37.7749, long: -122.4194 },
startListening: jest.fn()
});

render();

expect(screen.getByText(/37.7749/)).toBeTruthy();
expect(screen.getByText(/-122.4194/)).toBeTruthy();
});
`

📊 Performance Considerations

$3

- Lightweight: ~5KB gzipped
- No memory leaks: Proper cleanup on unmount
- Minimal re-renders: Uses refs for internal state

$3

- Efficient: Callback-based, no polling
- Battery optimized: Uses WiFi/cellular over GPS when possible
- Smart updates: Distance filter prevents unnecessary callbacks

$3

- No dependencies: Pure geolocation API usage
- User-controlled: You control when/how to send data
- Bandwidth efficient: Only lat/long values (16 bytes)

🔄 Migration Guide

$3

Before:
`tsx
useEffect(() => {
Geolocation.getCurrentPosition(
position => setLocation(position.coords),
error => console.log(error)
);
}, []);
`

After:
`tsx
import NewLocationProvider, { useLocation } from '@eyuphantilki/location-listener';

// Wrap app




// Use hook
const { location } = useLocation();
`

$3

Most location libraries expose similar patterns. Simply:

1. Remove old library
2. Install @eyuphantilki/location-listener
3. Replace provider component
4. Replace hook calls
5. Update permission handling

❓ FAQ

Q: Does this work with Expo?
A: Yes, as long as you have @react-native-community/geolocation installed or use expo-location.

Q: Can I use this for background location tracking?
A: The package supports foreground tracking. For background tracking, you'll need additional native modules and permissions.

Q: How accurate is the location?
A: With enableHighAccuracy: false, accuracy is typically 10-100 meters. Enable high accuracy for GPS-level precision (5-20 meters).

Q: Does this drain battery?
A: The default settings are optimized for battery life. Battery usage is minimal with enableHighAccuracy: false` and reasonable update intervals.

Q: Can I customize the retry logic?
