I notice that in the code example above, the updater function passed to setState is impure, and when rendering app inside <React.StrictMode /> during development, react will run the updater twice facebook/react#12856 (comment)

so can we implement undo feature in a better pattern?

I'm not sure where it is an issue in all places, but WebSocket's message that was sent to clients is array buffer and sending it via JSON.stringify makes JSON.parse face error in useSocket

converting it to JSON first and then stringifying it to make it work for me.

  ws.on('message', function incoming(message) {
     history.push(...JSON.parse(message));
     connections
       .filter(client => client !== ws)
       .forEach(client => {
         client.send(JSON.stringify(JSON.parse(message)));
       });
   });
