Fork me on GitHub

hey all, I'm looking for a way to handle errors and roll back my app state to a 'last known good point' - is there any way to register a listener of some kind on the entire React tree so that it lets me know when all components have finished re-rendering on change?


failing a clean render listener, I guess I can just snapshot a second or so after the state has changed unless an error flag has been raised, but that seems.... iffy..
