A quick way to stage and application to nodejitsu (doesn't yet copy environment variables)

staging.js

/*
 * Use this file to deploy an app to the staging server on nodejitsu.
 */

var fs = require('fs');
var package = '';
var bash = require('child_process');
var jitsu;

// Save a backup of package.json, alter the current one, deploy to nodejitsu,
// and upon successful deploy, restore the package.json to it's original form.
fs.readFile('package.json', {encoding: 'utf-8'}, function (err, data) { // grab the package.json file contents
  if (err) throw err;
  package = JSON.parse(data);
  fs.rename('package.json', 'production-package.json'); // rename the package.json file
  package.name = 'stajing'; // alter json
  package.subdomain = 'stajing'; // alter json
  package.domains = []; // alter json
  fs.writeFile('package.json', JSON.stringify(package, null, 2), function(err) { // write the new package to package.json
    if (err) throw err;

    // Do `jitsu deploy` now with the new package.json.
    jitsu = bash.spawn('jitsu', ['deploy'], { // Spawn Bash instance to deploy to staging drone.
      cwd: process.cwd(),
      stdio: 'inherit'
    });

    // If `jitsu deploy` yields an error...
    jitsu.on('error', function (code, signal) {
      if(error) {
        console.log("Some kind of Bash Error: ", code, signal);
        return bash.disconnect();
      }
    });

    // If `jitsu deploy` exits successfully...
    jitsu.on('exit', function (code, signal) {
      if (code === 0) {
        fs.unlink('package.json', function (err) {

          fs.rename('production-package.json', 'package.json');
          return console.log("App staged successfully : )");
        });
      } else {
