almost all of the mentioned issues have solutions out their but the author is jumping around the stack with no sense of true purpose. How does graphql impact your SPA updating views, it doesn’t..
Of course it does, because GraphQL allows you to roll up queries for separate entities and get the data back for those in a single HTTP request. And that capability is something Relay and Apollo take advantage of. In this way a component can reference only the data it needs and the query rollup and caching happens automatically.
