If you're interested in an example of really good tooling and DevEx for GraphQL, then may I shamelessly promote this video in which I demonstrate the Isograph VSCode extension: https://www.youtube.com/watch?v=6tNWbVOjpQw

TLDR, you get nice features like: if the field you're selecting doesn't exist, the extension will create the field for you (as a client field.) And your entire app is built of client fields that reference each other and eventually bottom out at server fields.
