如何拆分很长的 GraphQL 模式 [英] How to split a long GraphQL schema

问题描述

我正在尝试创建一个架构，但是会变得太长和混乱，拆分不同的查询、突变和输入的最佳实践是什么，以便我可以只需要它们并组织它们以使其易于阅读.

I am trying to create a Schema, however is going to get too long and confusing, what are the best practices to split the different queries, mutations and inputs so I can just require them and organize them to make it easy to read.

我试图在网上查找信息，但没有任何明确的信息，我尽量不使用 Apollo.

I have tried to find information online but there is nothing clear at all and I am trying not to use Apollo.

const { buildSchema } = require('graphql');

module.exports = buildSchema(`
type Region {
  _id: ID!
  name: String!
  countries: [Country!]
}

type Country {
  _id: ID!
  name: String!
  region: [Region!]!
}

type City {
  _id: ID!
  name: String!
  country: [Country!]!
}

type Attraction {
  _id: ID!
  name: String!
  price: Float!
  description: String!
  city: [City!]!
}

type Eatery {
  _id: ID!
  name: String!
  cuisine: String!
  priceRange: String!
  location: [Location!]!
  typeOfEatery: String!
  city: [City!]!
}

type Location {
  _id: ID!
  latitude: String!
  longitude: String!
  address: Float
}

type User {
  _id: ID!
  email: String!
  password: String!
}

type AuthData {
  userId: ID!
  token: String!
  tokenExpiration: String!
}

type RegionInput {
  name: String!
}

type CountryInput {
  name: String!
}

type CityInput {
  name: String!
}

type RootQuery {
  regions: [Region!]!
  countries: [Country!]!
  login(email: String!, password: String!): AuthData!
}

type RootMutation {
  createRegion(regionInput: RegionInput): Region
  createCountry(countryInput: CountryInput): Country
  createCity(cityInput: CityInput): City
}

schema {
  query: RootQuery
  mutation: RootMutation
}
`);

我需要一些非常有条理的东西，让我可以把所有东西都整理得井井有条，将所有文件合并到一个索引中是最好的解决方案.

I need something that is very organized and allows me to get everything in order and clear, merge all files in one index is the best solution.

推荐答案

有多个选项，这里是其中三个:

There are multiple options, here are three of them:

1. 你可以看看 Apollo 的博客——他们展示了一种模块化架构的方法:模块化你的 GraphQL 模式代码如果你想要一个例子，你可以看看这个 github 仓库

1. You can take a look at Apollo's blog - they show a way to modularize the schema: Modularizing your GraphQL schema code If you want an example, you can take a look at this github repository

当然，您始终可以只使用模板文字将架构的一部分嵌入为字符串:

Of course you can always just use the template literals to embed parts of the schema as strings:

const countryType = `
type Country {
  _id: ID!
  name: String!
  region: [Region!]!
}
`

const regionType = `
type Region {
  _id: ID!
  name: String!
  countries: [Country!]
}
`

const schema = `
${countryType}
${regionType}

# ... more stuff ...
`

module.exports = buildSchema(schema);

1. 另一种方法是使用代码优先的方法，并用 javascript 而不是 graphql 模式语言编写模式.
