optimistic updates

Are you guys working on optimistic updates like firebase does... ?

Basically on any add or modify of a table, it would automatically update the DOM (or cache) asynchronously while waiting on the confirmation from the database to change...

This is how firebase works. I know this is a similar question to offline support, but I look at this differently. You could technically do this in react or angular on its own by setting values to a variable that binds to the DOM and gets updated by the websockets, but doing this automatically would be a plus.

Thanks,
