Shiny Web UIs

I think the correct usage is:

var Blynk = require('http://tiny.cc/blynk-js');
var blynk = new Blynk.Blynk('715f8caae9bf4a91bae319d0376­caa8d', options = {
  certs_path : '../certs/'
});
var v1 = new blynk.VirtualPin(1);
var v9 = new blynk.VirtualPin(9);

v1.on('write', function(param) {
  console.log('V1:', param);
});

v9.on('read', function() {
  v9.write(new Date().getSeconds());
});

The link to the node.js module is a bit confusing... But to be honest the code itself is relatively compact, and can be auto-minified (via Web IDE settings) so shouldn't use up too much space.

No, you'd have to upload to the Espruino to verify it I'm afraid - to check it more sensibly I'd really need to run an Espruino instance in the web browser :)
