How to utilise RequireJS and still access Drupal(7) JS API?
Woops, I'm not sure how the explanation got lost!

The script include:

&lt;script id="requirejs" data-rev="1485975293" data-main="main.js?rev=1485975293" src="require.js?rev=1485975293"&gt;&lt;/script&gt;


Alright, so this is in my main.js (data-main) file, that requirejs uses for loading up the dependencies and all that.  

I'm just posting the relevant code block here (notice the Drupal.attachBehaviors(document, Drupal.settings); at the end:

    require([
      'jquery',
      'underscore',
      'intentcontext',
      'app',
      'primary-menu'
      ], function ($, _, IntentContext, app) {
      'use strict';

       // DOM ready
      $(function() {

        // js loaded only on homepage
        if ($('body').hasClass('front')) {
          require(['homepage']);
        }

        /*
         * loaded js for foundation and intention
         */
        require(['foundation']);
        require(['intentinit']);

        // call drupal behaviors
        Drupal.attachBehaviors(document, Drupal.settings);
      }); // DOM ready
    });


And then example of a dependent js module (primary-menu.js):

    define([
      'jquery',
      'intentcontext'
    ], function ($, IntentContext) {
      'use strict';

      /*
       * constructor
       */
      var PrimaryMenu = function(context, settings) {
        var
          self = this;

        self.$elm = $(context).find('#block-system-main-menu');
        $('body').once('primaryMenu').each(function() {
          self.init();
        });
      }; // PrimaryMenu constructor

      /*
       * on document ready with drupal behaviors
       */
      (function($, Drupal) {
        Drupal.behaviors.primaryMenu = {
          attach: function(context, settings) {
            var
              primaryMenu = new PrimaryMenu(context, settings);
          }
        };
      }(jQuery, Drupal));
    });


Hope that helps.
