Websockets

Websocket support in Rhino is provided by ActionCable and Solid Cable and is configured by default.

Rhino provides websocket authentication by default, but NOT authorization - ensure the user has access to the data they are requesting.

Creating a channel

Create a channel with standard rails generator:

rails g channel Test

Connecting to a channel

The front end provides a useCable hook that can be used to connect to a channel.

const consumer = useCable();
const [messages, setMessages] = useState([]);

useEffect(() => {
  if (!resource?.id) return;

  consumer.subscriptions.create(
    { channel: "TestChannel", id: resource.id },
    {
      connected() {},
      received(data) {
        setMessages((currentValues) => {
          const a = [...currentValues, data];

          return a;
        });
      },
    }
  );
}, [consumer, resource.id]);
