Subscribe to immediate live updates from your server

While polling for changes is a simple, safe solution, sometimes we'd like updates pushed to us by the server as soon as they happen. We might also like small chunks of updates, rather than re-requesting the whole initial query. In this lesson, we'll look at making GraphQL subscription with the "useSubscription" hook. We'll also set-up a conditional protocol link, that either uses the HTTP or Websocket protocols based on the type of query being attempted.
