react-native-app-state-higher-order-component v0.1.1

🌈 react-native-app-state-higher-order-component

A React Native higher-order component listening to AppState changes.

Installation

npm install react-native-app-state-higher-order-component --save

Usage

Import withAppStateListener from this library.

import { withAppStateListener } from 'react-native-app-state-higher-order-component';

Call withAppStateListener with the component you'd like to extend with it's functionality.

const EnhancedComponent = withAppStateListener(YourComponent);

Your component now receives an appState prop, which updates to the AppState.currentValue (i.e. 'active', 'inactive', 'background') value every time AppState updates.

import { Text } from 'react-native';
import { withAppStateListener } from 'react-native-app-state-higher-order-component';

const YourComponent = (props) => {
  const { appState } = props;
  return <Text>{appState}</Text>;
}

const YourComponentWithAppState = withAppStateListener(YourComponent);

Extended Props

A component enhanced with withAppStateListener is extended with three optional, additional props:

Pass these optional props to your component enhanced with withAppStateListener:

import { Text } from 'react-native';
import { withAppStateListener } from 'react-native-app-state-higher-order-component';

const YourComponent = (props) => {
  const { appState } = props;
  return <Text>{appState}</Text>;
}

const YourComponentWithAppState = withAppStateListener(YourComponent);

const YourApp = () => {
  const onAppStateChange = (appState) => {
    console.log(`AppState updated to: ${appState}`);
  }

  const onBackground = () => console.log('App is in the background.');
  const onForeground = () => console.log('App is active.');

  return (
    <YourComponentWithAppState
      onAppStateChange={onAppStateChange}
      onBackground={onBackground}
      onForeground={onForeground}
    />
  );
}
