I recently built https://github.com/siriusastrebe/jsynchronous https://github.com/siriusastrebe/jsynchronous which uses event sourcing to synchronize javascript variables on the server with connected browsers. You can also replay states using a special “rewind” mode, a core advantage of event sourcing.
