title: Download MS Excel/Word via AngularJS call to a REST service
body: <p>I have an AngularJS application that sends a POST request to a REST service (onClick method of a button). The POST request contains a JSON object with various settings. The REST service uses those settings to create a MS Word/Excel file.</p>
  
  <p>At the moment the REST service sends the contents of the file back as a byte stream (in response to the previously mentioned POST request). When the file arrives I want a save-file-dialog to show up, where I can save the file. The backend is a Spring Boot app using Spring-MVC.</p>
  
  <p>Can this be done in AngularJS?</p>
