How to utilize Yeoman, AngularJS data, and Node.js to upload data into the Heroku starter database?

My app is using Yeoman, AngularJS. I'm fairly new to it and so this questions is regarding managing data. Currently I am hard coding my data into an array of JSON object in my main.js file as such

angular.module('myApp')
.controller('AdminCtrl', ['$scope', '$filter', function($scope, $filter) {
    //<--ARRAY OF DATA with multiple attributes<--
    $scope.campaigns = [
    { name:'', description'', etc... etc...},
    {...Lots of Data...},
    {...Lots of Data...},
    {...Lots of Data...},
    {...Lots of Data...},
    ];
}]);

I am already deploying the site via heroku and so I wanted to upload this data into the starter dev Heroku Postgres Database. This is my first time uploading data to the heroku database and was wondering how I would go about this process. I want to use Node.js (also new for me) and I found this article (https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-node-js) but is this all I have to do? Where and how do I transfer my current array data into Node.js and then upload it to heroku?

Edit: I followed the http://www.sitepoint.com/deploying-yeomanangular-app-heroku/, and http://www.lars-schenk.com/deploying-a-yeoman-angular-app-to-heroku/1661 articles (basically the same it seems) that @montecruiseto suggested and did a "grunt build" but the data is still lost when I refresh the page. This is my first time using Node.js but I believe these examples are deploying a static angular app without dynamic data update. What are the steps I need to take to take my current array data and utilize the "web.js" to make it persist up in the Heroku database?
