@errtap/react-native

React Native SDK for ErrTap — hooks the global ErrorUtils runtime for uncaught JS errors without importing React Native internals. Repeated init calls are idempotent. Production Hermes promise rejections are captured when the runtime provides its rejection-tracker hook.

npm i @errtap/react-native

// App.tsx (or index entry — call once at startup)
import { init } from '@errtap/react-native';

init({
  dsn: process.env.EXPO_PUBLIC_ERRTAP_DSN!, // https://et_…@host
  environment: __DEV__ ? 'development' : 'production',
  release: '1.0.0',
});

Keep crash reports that happen offline

A fatal JS error ends a release build, so ErrTap holds React Native's crash handler for up to 2 seconds while the report is sent. Pass a key-value store and a crash that can't be sent in time (offline, flaky network) is saved and delivered on next launch:

import AsyncStorage from '@react-native-async-storage/async-storage';

init({ dsn: process.env.EXPO_PUBLIC_ERRTAP_DSN!, release: '1.0.0', storage: AsyncStorage });

Manual capture / logs:

import { captureException, logger } from '@errtap/react-native';

logger.info('checkout started');
try {
  await pay();
} catch (e) {
  captureException(e as Error);
  throw e;
}
