Module not found in angularjs
Many has fallen into the same trap. Me included.
The following does not define a new module. It will try to retrieve a module named UserHandler which isn't defined yet.
angular.module('UserHandler')Providing a (empty) array of dependencies as the second argument will define your module.
angular.module('UserHandler', [])
I am new to javascript and have spent a couple of hours to discover my issue. The module initialization function can be ignored. To avoid this, do not forget to add empty parenthesis to the end of a function:
(function() { "use strict"; var app = angular.module("app", []); })(); //<<---Here
Also, don't forget to add the new module in your index.html:
<script src="app/auxiliary/test.module.js"></script><script src="app/auxiliary/test.route.js"></script><script src="app/auxiliary/test.controller.js"></script>
