Import interfaces from source schema

[pmelab]

Is it possible to define an interface in my source schema and properly reflect it in the Gatsby schema?

Example:

interface Person {
  name: String!
}

type Employee implements Person {
  name: String!
  department: String!
}

type Client implements Person {
  name: String!
  company: String!
}

Both Employee and Client are nodes that are sourced to Gatsby, but the interface is dropped entirely. If a field returns the Person type, the interface will be created and correctly applied to Employee and Client, but it won't contain any fields except remoteTypeName.

I would be great to be able to run a reusable fragment against an interface:

fragment Person {
  name
}

But if i'm not mistaken, this is not possible right now?
