title: React service worker not working?
body: <h1>Hello Guys !</h1>
  
  <p>Today I deployed an app online to test it but didn't understood very well why it didn't work.</p>
  
  <h2>What I did :</h2>
  
  <p>I've created a <code>sample react app</code> using <code>bootstrap</code> and used <code>firebase</code> to deploy it. <a href="https://testingsw-ebe1c.firebaseapp.com/" rel="nofollow noreferrer">Here is the link</a>.</p>
  
  <h2>What was expected ?</h2>
  
  <p>I wanted the app to be able to be downloaded on the phone as <a href="https://angular.io/" rel="nofollow noreferrer">angular.io</a> is.</p>
  
  <h2>Reality :</h2>
  
  <p>Nothing special. It's in fact registered in service worker and very fast to load and download, but nothing more.</p>
  
  <h2>Problem now :</h2>
  
  <p>I've done it today two times but wasn't able to use it as well as the image of service workers I had.</p>
  
  <p>What should I do ?</p>
