title: Why does my Angular PWA fails on Lighthouse PWA audit while everything work fine when i manually test it?
body: <p>I you go to the app <a href="https://quotesaboutjesus.netlify.com/quotes" rel="nofollow noreferrer">https://quotesaboutjesus.netlify.com/quotes</a> and look at Application tab in Chrome Dev tool, you'll see after few seconds the service worker runing well... and the app work well in online mode.</p>
  
  <p>But Lighthouse audit result always says me : </p>
  
  <ul>
  <li><strong>Current page does not respond with a 200 when offline</strong>.</li>
  <li><strong>start_url does not respond with a 200 when offlineThe start_url did respond, but not via a service worker.</strong></li>
  <li><strong>Does not register a service worker that controls page and start_url</strong></li>
  </ul>
  
  <p>But as you'll see in my <a href="https://github.com/WilChrist/QAJ-APP-FE" rel="nofollow noreferrer">code here</a> or directly in <a href="https://github.com/WilChrist/QAJ-APP-FE/blob/master/src/manifest.webmanifest" rel="nofollow noreferrer">my manifest.webmanifest here</a>, i did (i think ?: because Lighthouse says me i didn't) :</p>
  
  <ol>
  <li>add a web app manifest.</li>
  <li>Check that the start_url in your manifest is correct.</li>
  <li>Add a service worker to your app.</li>
  <li>Use the service worker to cache files locally.</li>
  <li>When offline, use the service worker as a network proxy to return
  the locally cached version of the file.</li>
  </ol>
  
  <p>So i don't understand why i fails the audit test (you can easily reproduce it yourself <a href="https://quotesaboutjesus.netlify.com/quotes" rel="nofollow noreferrer">online</a>).</p>
  
  <p>i imagined that it can be cause by the fact that my SW register a little late, so i try to optimise the performance of the app, but even now it has better performances score (90 at least during audit test), it's didn't pass this test.</p>
  
  <p>Can someone help me ?</p>
