title: Show loading bar for every http request angular2
body: <p>I am moving my app from angularjs to angular2. I was using <code>Angular Loading Bar</code> which is </p>
  
  <blockquote>
    <p>An automatic loading bar using angular interceptors. It works
    automatically, so simply include it as a dependency and it will
    automatically display the progress of your $http requests.</p>

  <p>I am trying to find similar plugin in angular2. I came across a few like <code>ng2-slim-loading-bar</code> but here I have to manually manage the progress. For every http request, I have to manually start the progress bar and then finish it. </p>
  
  <p>So, are there any existing plugin available which can do exactly what <code>Angular Loading Bar</code> does in angularjs. Or how can I modify any existing plugin to behave like this.</p>
