I don't use GraphQL and I have subscriptions or real time updates as well. On the backend whenever I do a equivalent of INSERT, UPDATE, DELETE I send a message over a websocket connection out to the connected clients. The client sends it's context whenever that changes so that the client only receives the necessary updates. I don't need GraphQL for that and I know what my code does, but with GraphQL I don't. I use Go on the server side and Angular or Flutter on the client side.
