Nested query for the new GraphQL buildSchema

Question

How can I make resolver for my friendList with the new GraphQL Schema language? friendList have an array of people _id.

My new people type with GraphQL Schema language:

const schema = buildSchema(`
  type People {
    _id: String
    firstName: String
    lastName: String
    demo: String
    friendList: [People]
  }
  type Query {
    getPeople(_id: String): People
  }
`);

My old people type with GraphQLObjectType:

const PeopleType = new GraphQLObjectType({
  name: 'People',
  fields: () => ({
    _id: {
      type: GraphQLString,
    },
    firstName: {
      type: GraphQLString,
    },
    lastName: {
      type: GraphQLString,
    },
    friendList: {
      type: new GraphQLList(PeopleType),
      // pass @friends parentValue
      resolve: ({ friends }) {
        return People.find({ _id: { $in: friends } }).then(res => res);
    },
  }),
});

I want to achieve this query:

{
  people(_id: "ABC123") {
    firstName
    lastName
    friendList {
      firstName
      lastName
    }
  }

did you ever find the answer to this? Struggling through this myself right now. — Charles Burgess

Your resolver should return a new instance of a class as explained in the updated GraphQL documentation: http://graphql.org/graphql-js/object-types/.

class People {
  friendList () {}
}
var rootValue = {
  getPeople: function () {
    return new People();
  }
}
