Installation

npm i graphql graphql-yoga

Start

Provide the database GraphQL schema.

examples/server/graphql-yoga/index.ts

import { createServer } from 'node:http';
import { createYoga } from 'graphql-yoga';
import { sessionIdFromCookie, sessionIdToCookie } from '@server/common';
import { buildSchema, createContext } from '@database/mongodb/schema';
 
const SESSION_REQUEST_TO_ID_MAP = new WeakMap<Request, string>();
 
const yoga = createYoga({
  schema: await buildSchema(),
  context: ({ request }) =>
    createContext({
      sessionId: sessionIdFromCookie(request.headers.get('cookie')),
      setSessionId(sessionId) {
        SESSION_REQUEST_TO_ID_MAP.set(request, sessionId);
      },
    }),
  plugins: [
    {
      onResponse({ request, response }) {
        const sessionId = SESSION_REQUEST_TO_ID_MAP.get(request);
        if (sessionId) {
          response.headers.set('set-cookie', sessionIdToCookie(sessionId));
        }
      },
    },
  ],
});
 
const server = createServer(yoga);
 
server.listen(50005, () => {
  console.info('Server is running on http://localhost:50005/graphql');
});

And run it:

npx tsx index.ts

Visit http://localhost:50005/graphql (opens in a new tab) to see Yoga in action.
