Angular 2 HTTP JSON Service

Live Demo
Github Repo

Here is a bare minimum demo of how to use Angular 2 HTTP JSON Service:https://github.com/huguogang/ng2tsdemo/blob/master/json_service.html

The demo uses observable instead of promise. A few potential catches:

• Import Rx.js in html file:

  <script src="node_modules/rxjs/bundles/Rx.js"></script>
  

• Import rxjs/Rx in service:

  import 'rxjs/Rx'

• Register HTTP_PROVIDERS
