Running inside X Virtual Frame Buffer

[sriducati]

I have to nightmare script inside xvfb.

xvfb-run node cnn.js

cnn.js has....

var Nightmare = require('../nightmare');
var vo = require('vo');

vo(run)(function(err, result) {
  if (err) throw err;
});

function *run() {
  var nightmare = Nightmare();
  var title = yield nightmare
    .goto('http://cnn.com')
    .evaluate(function() {
      return document.title;
    });
  console.log(title);
  yield nightmare.end();
}

is there a way to write the whole code inside X Virtual Frame Buffer, so that we can execute in normal way

node cnn.js instead of xvfb-run node cnn.js
