⚛ Enhances the reliability of managing app lifecycles across iOS and Android platforms, ensuring consistent behavior regarding foreground and background states.

It implements the Lifecycle for Android and falls back to the AppState for iOS.

The original AppState API provided by React Native behaves differently between Android and iOS, particularly regarding the background state:

• On iOS, the background state signifies that the entire app is in the background.
• On Android, the background state indicates that the React Native Activity is in the background, which might not necessarily mean the entire app is in the background.

By using react-native-applifecycle, you can handle these differences seamlessly across both platforms, ensuring that the state background will be dispatched only when the entire app is in background.

Install dependency package

yarn add react-native-applifecycle

Or

npm i -S react-native-applifecycle

The App Lifecycle API is compatible with the original AppState.

import {AppLifecycle} from 'react-native-applifecycle';

const App = () => {

  useEffect(() => {
    const listener = AppLifecycle.addEventListener('change', state => {
      // do something
    });

    return () => listener.remove();
  }, []);

  return <View />;
}

export default App;

import {useAppLifecycle} from 'react-native-applifecycle';

const App = () => {
  const currentLifecycle = useAppLifecycle();

  // do something

  return <View />;
}

export default App;

For more details, see the Sample Project.

• active - The app is running in the foreground
• background - The app is running in the background. The user is either:
  • in another app
  • on the home screen
• [iOS] inactive - This is a state that occurs when transitioning between foreground & background, and during periods of inactivity such as entering the multitasking view, opening the Notification Center or in the event of an incoming call.

For more information, see React Native documentation.

This event is received when the app state has changed. The listener is called with one of the current app state values.

Falls back to AppState

static addEventListener(
  type: AppStateEvent,
  listener: (state: AppStateStatus) => void,
): NativeEventSubscription;

Sets up a function that will be called whenever the specified event type on Lifecycle occurs. Valid values for eventType are listed above. Returns the EventSubscription.

static currentState: AppStateStatus;

jest.mock('react-native-applifecycle/dist/AppLifecycle', () => require('react-native-applifecycle/jest/AppLifecycleMock'));
