react-native-background-geolocation/mocks/react-native.js

The most sophisticated cross-platform background location-tracking & geofencing module with battery-conscious motion-detection intelligence

const listeners = new Set();

class NativeEventEmitter {
  addListener(event, cb) {
    const sub = { remove: () => listeners.delete(sub) };
    listeners.add(sub);

}

// The native module is a TurboModule: every data method returns a Promise (not the pre-migration
// callback convention). NativeModule.js returns these calls directly, so the mocks must resolve a
// Promise. `log`/`playSound` are fire-and-forget (void).
