modelToType(model, options)

Convert a mongoose model to graphql types.

You can use this type definition in graphql-tools to build an executable schema.

const CategorySchema = new Schema({
  type: String,
});

const BookModel = mongoose.model('Book', new Schema({
  category: CategorySchema,
  name: String,
}));

const typeDef = modelToType(BookModel, {
  extend: {
    Book: {
      publishers: '[Publisher]',
    },
    BookCategory: {
      genre: 'Genre',
    },
  },
});

console.log(typeDef);

Outputs:

type BookCategory {
  _id: String
  genre: Genre
  type: String
}
type Book {
  _id: String
  category: BookCategory
  name: String
  publishers: [Publisher]
}
