graphql-http

官方 graphql-http 包 提供了一种创建完全兼容的 GraphQL 服务器的简单方法。它有一个针对 Node.js 原生 http 的处理程序，以及针对 Express、Fastify 和 Koa 等知名框架的处理程序；以及不同运行时（如 Deno 和 Bun）的处理程序。

¥The official graphql-http package provides a simple way to create a fully compliant GraphQL server. It has a handler for Node.js native http, together with handlers for well-known frameworks like Express, Fastify and Koa; as well as handlers for different runtimes like Deno and Bun.

Express

import { createHandler } from "graphql-http/lib/use/express" // ES6
const { createHandler } = require("graphql-http/lib/use/express") // CommonJS

createHandler

function createHandler({
  schema,
  rootValue,
  context,
  formatError,
  validationRules,
}: {
  rootValue?: any,
  context?: any,
  formatError?: Function,
  validationRules?: any[],
}): Handler

基于 GraphQL 结构构造 Express 处理程序。
