在Apollo GraphQL中跨本地和远程模式对嵌套数组中的数据进行建模的最佳方法？

import { ApolloServer, gql } from 'apollo-server';
import DataLoader from 'dataloader';

// 模拟的数据源
const users = [
  { id: '1', name: 'User 1', posts: ['1', '2', '3'] },
  { id: '2', name: 'User 2', posts: ['4', '5'] },
];

const posts = [
  { id: '1', title: 'Post 1' },
  { id: '2', title: 'Post 2' },
  { id: '3', title: 'Post 3' },
  { id: '4', title: 'Post 4' },
  { id: '5', title: 'Post 5' },
];

// 创建数据加载器
const postLoader = new DataLoader(async (postIds) => {
  // 从数据源加载对应的数据
  const result = postIds.map((postId) => {
    return posts.find((post) => post.id === postId);
  });

  return result;
});

// 定义GraphQL模式
const typeDefs = gql`
  type User {
    id: ID!
    name: String!
    posts: [Post!]!
  }

  type Post {
    id: ID!
    title: String!
  }

  type Query {
    user(id: ID!): User
  }
`;

// 解析GraphQL查询
const resolvers = {
  Query: {
    user: (_, { id }) => {
      // 从数据源加载用户数据
      const user = users.find((user) => user.id === id);

      return user;
    },
  },
  User: {
    posts: (user) => {
      // 使用数据加载器批量加载帖子数据
      return postLoader.loadMany(user.posts);
    },
  },
};

// 创建Apollo服务器
const server = new ApolloServer({
  typeDefs,
  resolvers,
});

// 启动服务器
server.listen().then(({ url }) => {
  console.log(`Server running at ${url}`);
});
