Converting WordPress website to Progressive Web App
<p>I am building a Progressive Web App but there is a very little documentation and support online so far. I am listing down all my questions in this email.</p>

<ol>
<li><p>What is the current support of Service Worker API (Offline Mode) for
desktops? I wrote a small app which worked in offline mode for
mobile (Android-Chrome) but not for my Desktop (Chrome 42). We need
to configure development environment for this so we need to know
what will we be needing to test our apps. It doesn't work on
IOS-Safari/Chrome even.</p></li>
<li><p>The service work uses caches extensively and there is a very good
    way to debug or unregistered service worker internals on Dekstop
    Chrome; but if I run my application on Mobile how would I remove
    service worker cache?</p></li>
<li><p>If I have a responsive application (A WordPress site) and need to
    convert it into PWA; would I need to rewrite the application with
    RestAPI for mobile version all again? (Read App Shell of PWA). In
    PWA, application shell is separate from data however in CMS like
    WordPress data is not separate from the UI.</p></li>
</ol>

<p>I have been looking for these answers for very long and not being able to find any proper support.</p>
