title: CI CD Pipeline for Angular4 Application in VSTS with Multiple Environment Azure
body: <p>I have an Angular 4 front end application which doesn't have any backend like java or .Net. Just a frontend UI which I need to host in Azure as Web App. It have few sets of environment specific variables. Right now I have Separate Builds and Release for each environment specific. This is a kind of tedious work when I need to build and deploy each and every time.</p>
  
  <p>Questions are:</p>
  
  <ol>
  <li>I would like to know how to read App Settings that are in Azure App service in Angular 4.</li>
  <li>How can be have a single build and just change the app settings for each environment specific.</li>
  </ol>
  
  <p>Thanks in advance.</p>
