React Native Restart: How to Do That?

To restart a React Native app, you can use the restart function from the react-native-restart package. To install this package, run the following command:

npm install react-native-restart

or

yarn add react-native-restart

Then, you can use the restart function as follows:

import { restart } from 'react-native-restart'; function restartApp() { restart(); }

You can call the restartApp function wherever you want to restart the app, such as in response to a button press or after some asynchronous operation has completed.

It's important to note that the react-native-restart package only works on iOS and Android. If you are targeting other platforms, you will need to use a different approach to restart the app.

Alternatively, you can also use the AppState API from the react-native package to detect when the app is backgrounded or terminated, and then manually reload the app when it is brought back to the foreground. Here is an example of how to do this:

import { AppState, View, Text } from 'react-native';

function App() {
  const [appState, setAppState] = useState(AppState.currentState);

  useEffect(() => {
    AppState.addEventListener('change', handleAppStateChange);
    return () => {
      AppState.removeEventListener('change', handleAppStateChange);
    };
  }, []);

  function handleAppStateChange(newAppState) {
    if (appState.match(/inactive|background/) && newAppState === 'active') {
      console.log('App has come to the foreground!');
      // You can reload the app here
    }
    setAppState(newAppState);
  }

  return (
    <View>
      <Text>Current app state: {appState}</Text>
    </View>
  );
}

This example uses the useState and useEffect hooks to listen for changes to the app state, and it logs a message when the app is brought to the foreground. You can modify the example to reload the app when the app is brought to the foreground by calling ReactNative.restartApp() or by using a different approach.
