Multi-functional Directives in Angular

I have developed a versatile directive that I want to be able to use on any Angular page within our website. I do not want to constrain each page to using the same app variable. Can someone provide guidance on how I can modify this directive to make it generic so that it can simply be added as a dependency (included in a separate js file, of course)?

var app = angular.module('myapp', []);

app.directive('helloWorld', function() {
 return {
  restrict: 'AE',
  replace: 'true',
  scope: {
  name: '@',
 },
 template: '<h3 >Hello {{name}}</h3> ',
   }
  };
});

To streamline your code, you can set up a common module where you define your directive and then include it as a dependency in each of your applications. By including the common module in your app's dependencies, you gain access to your directive as well as any providers you've specified in the common module.

/common.module.js

;(function() {

    var commom = angular.module('common', []);

    commom.directive('helloWorld', function() {
        return {
            restrict: 'AE',
            replace: true,
            scope: {
                name: '@',
            },
            template: '<h3 >Hello {{name}}</h3> ',
        };
    });

})();

/index.html

<html>
...
<body ng-app="myapp">

    <hello-world name="World"></hello-world>

    <script src="angular.min.js"></script>
    <script src="common.js"></script>
    <script>    
        var app = angular.module('myapp', ['common']);
    </script>
</body>
</html>
