@life-hack-tools/device-handoff

React Native / Expo QR handoff UI and payload helpers.

Features

• Show a QR code for the current app-owned identifier
• Scan a QR code with expo-camera
• Validate structured handoff payloads
• Keep app-specific storage and restore logic outside the package

Usage

import { DeviceHandoffModal } from '@life-hack-tools/device-handoff';

<DeviceHandoffModal
  visible={visible}
  value={userId}
  payloadType="my-app-handoff"
  labels={labels}
  onClose={() => setVisible(false)}
  validateValue={(value) => value.length > 0}
  onApplyValue={async (nextValue) => {
    await saveUserId(nextValue);
    await restoreRemoteData(nextValue);
  }}
/>

deviceId, onApplyDeviceId, and validateDeviceId remain available as backward-compatible aliases.

Data Restore

Use restoreRecords() when the scanned handoff key unlocks remote data and you need to merge that data into local storage.
