We all got really excited about React Native (both our mobile and our web people), but we don't have anywhere near the people-nhours needed to use it as our primary way of making views on mobile (at least not yet).
One idea that myself and some others had, though, was to utilize it as a data layer that we could share across our mobile and web platforms as we start to stabilize our APIs, with the native developers still making views in UIKit and Android in the interim.
Hence why I was asking if there was some way to have a top-level React component that would allow us to communicate with the React Native runtime (apologies if I'm using the wrong words to describe it here). That way we could share Flux stores/API endpoint specifications between these different platforms as needed.
Does that make any more sense? I also know that it goes a bit against the whole "learn once, write anywhere" thinking you all talked about at the conference.
