Adapters

The Teardown SDK uses adapters to abstract platform-specific functionality. This allows the SDK to work across different React Native environments (Expo, bare RN) and with different underlying libraries.

Adapter Types

Device Adapters

Collect device and application information for identification and analytics.

Adapter	Package	Use Case
`ExpoDeviceAdapter`	`expo-device`, `expo-application`	Expo projects
`DeviceInfoAdapter`	`react-native-device-info`	Bare RN projects
`BasicAdapter`	None	Fallback/testing

Storage Adapters

Handle persistent data storage for sessions, device IDs, and version status.

Adapter	Package	Use Case
`MMKVStorageAdapter`	`react-native-mmkv`	Fast sync storage (recommended)
`AsyncStorageAdapter`	`@react-native-async-storage/async-storage`	Broader compatibility

Notification Adapters

Handle push notification registration and token management.

Adapter	Package	Use Case
`ExpoNotificationsAdapter`	`expo-notifications`	Expo projects
`FirebaseMessagingAdapter`	`@react-native-firebase/messaging`	Firebase Cloud Messaging
`WixNotificationsAdapter`	`react-native-notifications`	Wix notifications library

Required Adapters

When initializing TeardownCore, you must provide:

const teardown = new TeardownCore({
  org_id: 'your-org-id',
  project_id: 'your-project-id',
  api_key: 'your-api-key',
  storageAdapter: new MMKVStorageAdapter(),    // Required
  deviceAdapter: new ExpoDeviceAdapter(),       // Required
});

Common Configurations

Expo Project

import { TeardownCore } from '@teardown/force-updates';
import { ExpoDeviceAdapter } from '@teardown/force-updates/adapters/expo';
import { MMKVStorageAdapter } from '@teardown/force-updates/adapters/mmkv';

export const teardown = new TeardownCore({
  org_id: 'your-org-id',
  project_id: 'your-project-id',
  api_key: 'your-api-key',
  storageAdapter: new MMKVStorageAdapter(),
  deviceAdapter: new ExpoDeviceAdapter(),
});

Bare React Native Project

import { TeardownCore } from '@teardown/force-updates';
import { DeviceInfoAdapter } from '@teardown/force-updates/adapters/device-info';
import { AsyncStorageAdapter } from '@teardown/force-updates/adapters/async-storage';

export const teardown = new TeardownCore({
  org_id: 'your-org-id',
  project_id: 'your-project-id',
  api_key: 'your-api-key',
  storageAdapter: new AsyncStorageAdapter(),
  deviceAdapter: new DeviceInfoAdapter(),
});

Custom Adapters

All adapter types can be extended for custom implementations. See individual adapter sections for interface definitions.
