Question 1

How to use react-native-boundary with Expo?

Accepted Answer

react-native-boundary requires native linking, so it's not compatible with Expo's managed workflow out of the box. You may need to eject to the bare workflow or use alternative libraries that support Expo.

Question 2

react-native-boundary vs react-native-geolocation for geofencing?

Accepted Answer

react-native-boundary is optimized for geofencing with native APIs, offering better battery efficiency for region monitoring. react-native-geolocation is better for continuous tracking but can drain battery faster if used for geofencing.

Question 3

How to set up background location permissions for react-native-boundary?

Accepted Answer

For iOS, add NSLocationAlwaysAndWhenInUseUsageDescription to Info.plist; for Android, add ACCESS_FINE_LOCATION permission in AndroidManifest.xml, as specified in the README's post-install instructions.

Question 4

Can I add multiple boundaries with react-native-boundary?

Accepted Answer

Yes, the library supports adding and managing multiple boundaries with unique IDs, and event callbacks can handle triggers from multiple boundaries, as shown in the usage code snippet.

Question 5

What is the accuracy of react-native-boundary geofencing?

Accepted Answer

Accuracy relies on native platform APIs; the README recommends a radius over 50 meters for consistency, suggesting smaller geofences might not trigger reliably due to platform limitations.

Question 6

How to fix react-native-boundary events not firing?

Accepted Answer

Ensure location permissions are correctly set, the radius is sufficiently large, and native linking is properly configured. Check event listeners and boundary IDs in your code, as per the API documentation.
