#### 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.
๐ 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', {

๐ง API Reference
$3
The main provider component that manages location tracking lifecycle.
Props:
| Prop | Type | Required | Default | Description |
|------|------|----------|---------|-------------|
| children | React.ReactNode | โ
Yes | - | Your app components that will have access to location context |
| onLocation | (loc: LocationType) => void | โ 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;
}
`
โ๏ธ 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 ร 1.5) | 5s |
| 3 | 4.5 seconds (3 ร 1.5) | 9.5s |
| 4 | 6.75 seconds (4.5 ร 1.5) | 16.25s |
| 5 | 10.125 seconds (6.75 ร 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
๐ก 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();
// โ Bad - Can crash
const distance = calculateDistance(location.lat, location.long);
// โ
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}
);
}
`
$3
The default settings are battery-optimized, but you can further optimize:
`tsx
// โ
Good - Use the package as-is for balanced performance
// โ 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);
`
๐ Troubleshooting
$3
Possible causes:
- โ Location permissions denied by user
- โ Location services disabled in device settings
- โ Using iOS simulator without location mock
- โ Android emulator without GPS mock
- โ 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 โ Location โ Custom Location
- Android Emulator: Extended controls (โฏ) โ Location
4. Check device settings:
- iOS: Settings โ Privacy โ Location Services
- Android: Settings โ Location โ App permissions
$3
Possible causes:
- โ Poor GPS signal (indoors, urban canyons)
- โ Device in airplane mode
- โ Location services in battery saver mode
- โ 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:
- โ enableHighAccuracy set to true
- โ Very low distanceFilter causing constant updates
- โ Very low interval causing frequent checks
- โ 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 โ "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 โ Signing & Capabilities
- Verify "Location" capability if using background location
3. Reset location permissions in simulator:
- Simulator โ Features โ Location โ Don't Simulate Location
- Then: Features โ Location โ Custom Location

๐ 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)
๐ 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
