Super interesting!
This seems like a pretty plausible way to add support for this sort of thing.
Have you looked at Schema stitching yet? We really need support for that to make it easier for people to pull in existing GraphQL schemas. Probably doesn't need to be done in this PR but an additional thing to be considering https://dev-blog.apollodata.com/graphql-schema-stitching-8af23354ac37

Per the API specification, this should be setSchemaFields https://www.gatsbyjs.org/docs/api-specification/#operators

Actually, let's make this createSchemaFields. There's no reason to allow people to override the default fields so we should validate against that.

@uttrasey you think you'll have time soon to finish this up? |
|
I've not had a chance to finish the site implementation and think it should wait for that. It's going to be a push for this year. We could close and re-open next year? |
|
Nah, not a big deal. We can leave it open. |

Hey, closing out old PRs. Would love to see you or someone else pick this up and carry it to the finish line! |
Raising a super rough PR to get early feedback.
Following on from the discussion here #2775 I've proposed a new API to allow sites/plugins to manipulate the GQL schema to do cool stuff. In my case I wanted to add a Union type which would allow me to query for 2 types at the same time. This has been achieved (very roughly) over here uttrasey/gatsby-union-demo#2
Assuming a path exists forward I'm keen to hear thoughts if it's possible to make use of some of the awesome stuff available in build-node-connections for filtering, paging, sorting etc.
What do folks think?
