Of course, you don’t have to code this functionality from scratch! You can also look at open-source software like Yjs, text-crdt, Automerge and so many more. Alternatively, you can check out tools like Liveblocks, Ably, etc. Which enable collaborative multi-player features. - Source: dev.to / 4 months ago

I write undo/redo/history in web/JS extensively. This the best lib out there for such tasks IMHO: https://github.com/yjs/yjs And you're right. You don't want undo/redo only in multi-user apps. You want to have each user have their own local undo/redo events that they can apply and unapply from the shared state which has its own events apart from each user.
