// Create an HTTP server
const server = http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('okay');
});
  
// Now that server is running
server.listen(3000, '127.0.0.1', () => {
  
console.log("Server is Started")
  // Make a request
  const options = {
    port: 3000,
    host: '127.0.0.1',
    headers: {
      'Connection': 'Upgrade',
      'Upgrade': 'websocket'
    }
  };
  
  // Getting client request

  // Aborting the request
  // by using abort() api
  req.abort()
  
  // checking if the client request
  // has been aborted or not
