add example using @interfaceObject directive

[oskargotte]

I was looking into adding an example using the @interfaceObject directive from federation v2.3, similar to what's outlined in #222. Is this of any value or is it better to add that to the subgraph compatibility testing repository where there are examples of all federation directives?

the subgraph compatibility is maybe even better.
Another idea is #215

Yes. Adding the compliance tool would be nice. But I'm not sure what's need in terms of subgraph support. Would it mean this repository would have a complete copy of the sangria folder? As a complement to the current example or as a replacement?

I'm sure I follow you.

• for the subgraph compatibility testing repository, we need to update https://github.com/apollographql/apollo-federation-subgraph-compatibility/blob/main/implementations/sangria/build.sbt#L10
• for Use Apollo federation spec compliance tool in CI #215, the idea would be to add spec compliance tool as github action in this repository. I haven't checked the details.

Yeah, this one seems fairly straight forward. I can open a draft PR in the compatibility repo for you to review. If you're ok with that?

But this one seems to be a bit more work. From what I understand it's not only adding the tool as a github action but it would also require this repository to implement the same kind of subgraph as the one in the subgraph compatibility testing repository.

of course! Thanks a lot!

Yes you're right.

Great! I'll try to target the first bullet then.

Please have a look when you have time: apollographql/apollo-federation-subgraph-compatibility#554

Closing this since there is now an example of @interfaceObject usage in apollographql/apollo-federation-subgraph-compatibility#555
