AppRegistry

Project with Native Code Required

If you are using the managed Expo workflow there is only ever one entry component registered with AppRegistry and it is handled automatically (or through registerRootComponent). You do not need to use this API.

AppRegistry is the JS entry point to running all React Native apps. App root components should register themselves with AppRegistry.registerComponent, then the native system can load the bundle for the app and then actually run the app when it's ready by invoking AppRegistry.runApplication.

React TSX

import {Text, AppRegistry} from 'react-native';

const App = () => (
  <View>
    <Text>App1</Text>
  </View>
);

AppRegistry.registerComponent('Appname', () => App);

To "stop" an application when a view should be destroyed, call AppRegistry.unmountApplicationComponentAtRootTag with the tag that was passed into runApplication. These should always be used as a pair.

AppRegistry should be required early in the require sequence to make sure the JS execution environment is setup before other modules are required.
