Basically, our framework works and reacts to offline state changes.
Currently, our experience is that users need to do some heavy lifting and manually fetch fresh and essential data when the application starts and when it becomes online again.
However, JS-SDK does not offer a way for them to actually know the network state so they cannot really react to it unless they duplicate the code. Our showcase is kinda hacking things to get this now. I think we can simply expose network interface with very quick fix and enable users to get access to network state events etc.
