Yes, I think think the Apollo Angular documentation should be updated to use the Apollo-recommendedgraphql-ws WebSockets implementation. We've replacedsubscriptions-transport-ws withgraphql-ws in our Apollo Angular project following thegraphql-ws Apollo Client Web Recipe but are still figuring out how to cleanly unsubscribe from all GraphQL Subscriptions on user sign-out, asgraphql-ws doesn't seem to have an equivalent to thesubscriptions-transport-wsSubscriptionClient.unsubscribeAll().
