相当于EnumSet的Typescript GraphQL

enum MyEnum {
  VALUE1,
  VALUE2,
  VALUE3,
  // ...
}

import { GraphQLObjectType, GraphQLList, GraphQLNonNull } from 'graphql';

const MyEnumSetType = new GraphQLObjectType({
  name: 'MyEnumSet',
  fields: {
    values: {
      type: GraphQLNonNull(GraphQLList(GraphQLNonNull(MyEnum))),
    },
  },
});

import { GraphQLSchema, GraphQLObjectType, GraphQLNonNull, GraphQLList } from 'graphql';

const QueryType = new GraphQLObjectType({
  name: 'Query',
  fields: {
    enumSet: {
      type: MyEnumSetType,
      resolve: () => {
        // 返回枚举值的集合
        return {
          values: [MyEnum.VALUE1, MyEnum.VALUE2],
        };
      },
    },
  },
});

const schema = new GraphQLSchema({
  query: QueryType,
});

query {
  enumSet {
    values
  }
}

{
  "data": {
    "enumSet": {
      "values": ["VALUE1", "VALUE2"]
    }
  }
}
