- Make it a Server method. - Pass Server instead of App. - Remove global app instance from NewServer, rather create local instances whenever needed. - Remove App from Websocket router, and create dynamically on every request. - Remove HubStart and HubStop from App methods. - Explicitly using s.Log instead of the global logger to indicate dependency on Server. We could have passed the logger explicitly but it doesn't look ideal. ```release-note NONE ```
