Add a module initializer

A module initializer is a JavaScript function that runs when the related module starts. This is useful for performing configuration or script loading before the edit user interface is available.

Configure the initializer in the module.config file for your app (add-on). The initializer attribute on the clientModule element determines the path to the module initializer to run. For example:

<clientModule initializer="acme/Initializer">
</clientModule>

The module initializer returns an object that has an initialize function. This function is called when the module initializer runs. Extend epi/_Module when implementing a module initializer because it implements the expected API and provides helper methods for common initializer actions. The skeleton for a module initializer looks like this:

define([
    'dojo/_base/declare',
    'epi/_Module'
  ],
  function (declare, _Module) {
    return declare([_Module], {
      initialize: function () {
        this.inherited(arguments);
      }
    });
  }
);
