graphql-http

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;

Constructs an Express handler based on a GraphQL schema.

See the tutorial for sample usage.
