Federation

I like what I’m seeing - I’m curious - I need to be able to add attributes for federation support

ie sample schema:

type Post @key(fields: "id") {
  id: ID!
  title: String!
  content: String!
  published: Boolean!
  createdAt: String!
  userId: Int
  user: User
}


extend type Query {
  posts: [Post!]!
  post(id: ID!): Post
}

extend type User @key(fields: "id") {
  id: ID! @external
  posts: [Post]
}

Is this possible ?

@sgentile Example should work with next version

/// @NG.Directive('@extends')
/// @NG.Directive('@key(fields: "id")')
model User {
    /// @NG.Directive('@external')
    id String @id
}

generator nestgraphql {
    fields_NG_from = "@nestjs/graphql"
    fields_NG_output = false
    fields_NG_model = true
}

Thank you!

Question… and I probably overlooked this: Apply ‘extends’ and @key is great’ there is another use case with this - you can see this in the post schema:

extend type User @key(fields: "id") {
  id: ID! @external
  posts: [Post]
}

This User type is not part of ‘Posts’ Prisma schema, however this is what links the above user model as shown here: https://github.com/sgentile/nest-apollo-federation/blob/main/posts-service/src/posts/schema.graphql

Just for reference this is then used in the resolver- ie.: @ResolveField(‘user’) getUser(@Parent() post: Post) { return { __typename: ‘User’, id: post.userId }; }
