Apollo Federation Spec Support

[audiolion]

Hi @rmosolgo 👋

Apollo announced their federation service today which enables the creation of a graphql gateway that merges multiple graphql schemas together under one graphql endpoint. Would graphql-ruby consider adding support for the Federation spec? It would enable people using graphql-ruby to easily compose multiple graphql apis into a single graphql gateway.

Based on this SO answer (https://stackoverflow.com/a/56432125/3271124) there is some hope in building this out ourselves before it is build-in with this gem. Creating few types, custom directives, and implementation should all be possible.

Has anyone had a chance to start? I will be exploring this pretty soon and will share any progress I got.

Hey, thanks for sharing that news! I'd be happy to include support along with GraphQL-Ruby, but personally I don't expect to have bandwidth for it until 1.10 (#2100) is done. If someone wants to implement it separately, please upstream any improvements to graphql-ruby that would make it easier to support!

I'm also starting to take a look at this in my own fork. Will use this issue to post future questions and progress 👋

I just published the first version of a Ruby implementation of Apollo Federation: https://github.com/Gusto/apollo-federation-ruby. It works alongside graphql-ruby. Please try it out and let me know what you think!

@rylanc that is awesome! Going to try this out next week

@rylanc Also going to give this a try this week, first glance it looks like a great start.

Thanks for your work on this @rylanc! Please do open an issue if there's anything we could do in GraphQL-Ruby to help you support it.
