Return Value: This method has nothing to return.

Example 1: Filename-index.js

Javascript

// Node.js program to demonstrate the
// request.setNoDelay() method

// Importing http module
const http = require('http');

// 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', () => {

  // Make a request
  const options = {
    port: 3000,
    host: '127.0.0.1',
    headers: {
      'Connection': 'Upgrade',
      'Upgrade': 'websocket'
    }
  };

  // Getting client request
  const req = http.request(options);

  req.host = '127.0.0.1'

  // Setting the nodelay for the socket
  // by using setNoDelay method
  req.setNoDelay(true);

  // Display the result
  console.log("no delay is set")

  process.exit(0)
});

Run the index.js file using the following command:

node index.js

Output:

no delay is set
