Can't start http server on node js?

Question

Node.js

The code:

var http = require('http');

var server = new http.Server();

server.listen(1337, '127.0.0.1');

server.on('require', function(req, res) {
  res.end("Привет Мир!");
});

console.log('Успешный запуск');

What the console outputs:

And nothing is displayed in the browser at 127.0.0.1:1337.
