Fastest WebSockets for node to node data exchange.

// use same options as: https://nodejs.org/api/tls.html, you need to generate own key.pem and cert.pem.
var options = {

  key: fs.readFileSync(__dirname + '/keys/key.pem'),

  requestCert: true
};

var server = nws.createServer(options, function(socket) {
