title: Cache busting static files(images, pdf's, png etc.) in assets folder for angular application?
body: <p>Our application is developed using angular-cli (version: 7.0.2) &amp; angular (version: 7.0.0).
  We have few image files, pdf's maintained in assets folder. These files change for every version of the app which releases every 3 months. </p>
  
  <ul>
  <li>What is the best way to achieve cache busting for all the files in assets folder?</li>
  <li>Is there a common technique which can be added to client app to load the latest of all files in assets folder whenever accessed? Is there any configuration which can be added in webpack.config.js (the file which gets generated when the project is created with angular-cli tool)?</li>
  </ul>
  
  <p>I read through various techniques mentioned in this link: <a href="https://stackoverflow.com/questions/1077041/refresh-image-with-a-new-one-at-the-same-url">Refresh image with a new one at the same url</a></p>
  
  <p>Not sure which is the best solution. Any suggestions / code snippets on how to implement cache busting is appreciated.</p>
