Detect application termination with react native

Question

Is there a way to detect when a react-native application will terminate?

I was thinking of componentWillUnmount at the main component level, do you think that's best way to do it?

I would like to send a "Save" request to the server before. I'm not sure if that's appropriate while the application in terminating, any better suggestion?

Thanks

According to https://github.com/facebook/react-native/issues/9348, it is not possible to do any cleanup on the JS side, you need to do it natively with applicationWillTerminate (which also means sync stuff between js and native code). I have an issue with my app terminating while running in the background, and I'm really looking forward to finding an explanation on how to do that.
