<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>

<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
System.import('app').catch(function(err){ console.error(err); });

<!-- 3. Display the application -->

Kindly help me what is going wrong.

I think that you have a problem in the template of your main component. For example a HTML element that isn't correctly closed:

template : '<div</div>'

See this issue for more details:


The problem is that your h1 isn't correct (no begin element):

  selector: 'my-app',
  template: '<h1>My first Angular 2 App</h1>' // <------
export class AppComponent {}
