Synopsis#

An example of a web server written with Node.js which responds with 'Hello World': 

const http = require('http');

http.createServer( (request, response) => {
  response.writeHead(200, {'Content-Type': 'text/plain'});
  response.end('Hello World\n');
}).listen(8124);

console.log('Server running at http://127.0.0.1:8124/');

To run the server, put the code into a file called example.js and execute it with the node program 

$ node example.js
Server running at http://127.0.0.1:8124/

All of the examples in the documentation can be run similarly.
