$ npm install googleapis

 var google = require('googleapis');
 var urlshortener = google.urlshortener('v1');
 var params = { shortUrl: 'http://goo.gl/xKbRu3' };
 // get the long url of a shortened url
 urlshortener.url.get(params, function (err, response) {
  console.log('Long url is', response.longUrl);
 });

 var google = require('googleapis');
 var plus = google.plus('v1');
 var oauth2Client = new OAuth2(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);
 // Retrieve tokens via token exchange explained above or set them:
 oauth2Client.setCredentials({
  access_token: 'ACCESS TOKEN HERE',
  refresh_token: 'REFRESH TOKEN HERE'
 });
 plus.people.get({ userId: 'me', auth: oauth2Client }, function(err, response) {
  // handle err and response
 });

 var fs = require('fs');
 var drive = google.drive({ version: 'v2', auth: oauth2Client });
 drive.files.insert({
  resource: {
  title: 'testimage.png',
  mimeType: 'image/png'
  },
  media: {
  mimeType: 'image/png',
  body: fs.createReadStream('awesome.png') // read streams are awesome!
