开源软件名称(OpenSource Name):ardatan/graphql-tools开源软件地址(OpenSource Url):https://github.com/ardatan/graphql-tools开源编程语言(OpenSource Language):TypeScript 98.4%开源软件介绍(OpenSource Introduction):This package provides a few useful ways to create a GraphQL schema:
DocumentationBinding to HTTPIf you want to bind your JavaScript GraphQL schema to an HTTP server, you can use You can develop your JavaScript based GraphQL API with ExampleWhen using const typeDefs = /* GraphQL */ `
type Author {
id: ID! # the ! means that every author object _must_ have an id
firstName: String
lastName: String
"""
the list of Posts by this author
"""
posts: [Post]
}
type Post {
id: ID!
title: String
author: Author
votes: Int
}
# the schema allows the following query:
type Query {
posts: [Post]
}
# this schema allows the following mutation:
type Mutation {
upvotePost(postId: ID!): Post
}
# we need to tell the server which types represent the root query
# and root mutation types. We call them RootQuery and RootMutation by convention.
schema {
query: Query
mutation: Mutation
}
`
export default typeDefs Then you define resolvers as a nested object that maps type and field names to resolver functions: const resolvers = {
Query: {
posts() {
return posts
}
},
Mutation: {
upvotePost(_, { postId }) {
const post = find(posts, { id: postId })
if (!post) {
throw new Error(`Couldn't find post with id ${postId}`)
}
post.votes += 1
return post
}
},
Author: {
posts(author) {
return filter(posts, { authorId: author.id })
}
},
Post: {
author(post) {
return find(authors, { id: post.authorId })
}
}
}
export default resolvers At the end, the schema and resolvers are combined using import { makeExecutableSchema } from '@graphql-tools/schema'
const executableSchema = makeExecutableSchema({
typeDefs,
resolvers
}) GraphQL-Tools schema can be consumed by frameworks like GraphQL Yoga, Apollo GraphQL or express-graphql For example in Node.js; const { createServer } = require('@graphql-yoga/node')
const server = createServer({
schema: executableSchema
})
server.start() You can check GraphQL Yoga for other JavaScript platforms and frameworks besides vanilla Node.js HTTP. This example has the entire type definition in one string and all resolvers in one file, but you can combine types and resolvers from multiple files and objects, as documented in the modularizing type definitions and merging resolvers section of the docs.
