Elastic Beanstalk deploy from a script and know when actually finished

Is there a to deploy an EB application from a script of some sort and know when it's actually up and running? git aws.push just returns when the git push is successful, but a lot of other stuff has to happen on EB before its live. I'm using Node.js if that helps. It'd be nice to be able to do something like:

console.log('Uploading to EB...');  
AWS.eb.push({
  onSuccess: function () {
    console.log('Push success!');
  },
  onFailure: function () {
    console.log('Push Failed!');
  },
  onDeploy: function () {
    console.log('This is actually live now!');
  }
});
