Teardown | Kill Old App Versions Instantly. Ship Without Fear. Build Boldly.

Device adapters collect device and application information for identification and analytics. You must provide a device adapter when initializing TeardownCore.

Available Adapters

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

Collected Information

All device adapters provide:

Application Info

interface ApplicationInfo {
  version: string;      // App version (e.g., "1.2.3")
  buildNumber: string;  // Build number (e.g., "45")
  bundleId: string;     // Bundle identifier (e.g., "com.example.app")
}

Hardware Info

interface HardwareInfo {
  deviceName: string;   // Device name (e.g., "iPhone 14 Pro")
  brand: string;        // Manufacturer (e.g., "Apple")
  deviceType: string;   // Device type (e.g., "phone", "tablet")
}

OS Info

interface OSInfo {
  osName: string;       // OS name (e.g., "iOS", "Android")
  osVersion: string;    // OS version (e.g., "17.0")
}

Usage

import { TeardownCore } from '@teardown/react-native';
import { ExpoDeviceAdapter } from '@teardown/react-native/adapters/expo';

const teardown = new TeardownCore({
  deviceAdapter: new ExpoDeviceAdapter(),
  // ... other options
});

Device ID

The SDK generates a stable device ID that persists across app sessions:

const deviceId = await core.device.getDeviceId();
// Returns a UUID that persists in storage

Custom Adapter

Implement the DeviceInfoAdapter interface:

import type { DeviceInfoAdapter, ApplicationInfo, HardwareInfo, OSInfo } from '@teardown/react-native';

class CustomDeviceAdapter implements DeviceInfoAdapter {
  get applicationInfo(): ApplicationInfo {
    return {
      version: '1.0.0',
      buildNumber: '1',
      bundleId: 'com.example.app',
    };
  }

  get hardwareInfo(): HardwareInfo {
    return {
      deviceName: 'Custom Device',
      brand: 'Custom',
      deviceType: 'phone',
    };
  }

  get osInfo(): OSInfo {
    return {
      osName: 'iOS',
      osVersion: '17.0',
    };
  }
}
