What’s Next

Being able to communicate with the server via polling is nice, but we still have a delay between when the change is made and when the server is polled. We could have a more direct update if the server were able to update the client when a change happens. A way to do that on the web is using the WebSocket protocol, and Rails provides ActionCable as a library for making WebSocket connections and broadcasting updates to clients. We’ll take a look at both ActionCable and WebSockets in the next chapter.
