在应用程序启动时反应原生 Android / iOS 调用 function

Question

I am new to React Native.

I am trying to call a react native method from native code without having any UI components from RN.

The idea is to add a DeviceEmitter listener at application start and later on post events from Native code.

The question is where should I put JS code to add DeviceEmitter listener at app start?

AppRegistry.registerHeadlessTask is probably where you should start.
