const server = http.createServer((req: http.IncomingMessage, res: http.ServerResponse) => {
  res.setHeader('Content-Type', 'application/json');
  const corsMiddleware = getCorsMiddleware();
  corsMiddleware(req, res);
  res.end('{}');
});

Example - SuGo Server

import { defaultOptions, getCorsMiddleware } from '@sugo/cors';
const corsMiddleware = getCorsMiddleware();
const server = createServer((req: SuGoRequest, res: SuGoResponse) => res.json({})).useMiddleware(corsMiddleware);

Example - default middleware
