Thats one of the really nice things about react: you can update the state on the clients copy of the board data, let react change the UI as required, then let the server send over the new state once it has one, update the clients state as required and let react deal with the ui updates.<p>As for reconcillation I would probably just have the server send over the entire current state of the board when the client connects. It is much easier and doesn&#x27;t waste that much bandwidth, which is cheap anyhow.<p>Am I missing something?
