import { makeHandler, handleProtocols } from 'graphql-ws/lib/use/lib/bun';
import { schema } from './previous-step';

Bun.serve({
  fetch(req, server) {
    const [path, _search] = req.url.split('?');
    if (!path.endsWith('/graphql')) {
      return new Response('Not Found', { status: 404 });
    }
    if (req.headers.get('upgrade') != 'websocket') {
      return new Response('Upgrade Required', { status: 426 });
    }
    if (handleProtocols(req.headers.get('sec-websocket-protocol') || '')) {
      return new Response('Bad Request', { status: 404 });
    }
    if (!server.upgrade(req)) {
      return new Response('Internal Server Error', { status: 500 });
    }
    return new Response();
  },
  websocket: makeHandler({ schema }),
  port: 4000,
});

console.log('Listening to port 4000');

Start the server with Deno

import { schema } from './previous-step.ts';

const handler = makeHandler({ schema });

serve(
  (req: Request) => {
    const [path, _search] = req.url.split('?');
    if (!path.endsWith('/graphql')) {
      return new Response('Not Found', { status: 404 });
    }
    if (req.headers.get('upgrade') != 'websocket') {
      return new Response('Upgrade Required', { status: 426 });
    }
    const { socket, response } = Deno.upgradeWebSocket(req, {
      protocol: GRAPHQL_TRANSPORT_WS_PROTOCOL,
      idleTimeout: 12_000,
    });
    handler(socket);
    return response;
