title: Right place for response parsing in PWA?
body: <p>I am building a magazine on top of a website.
  For this I am querying the public pages, and parsing the html content into JSON.</p>
  
  <p>Now, the simplest thing is to parse the html on the webpage/client.</p>
  
  <p>However with large payload my client will be busy for multiple frames, which is not desirable effect for a PWA.</p>
  
  <p>I am also using service workers.
  Is service worker the right place to do the parsing instead or just a web worker?</p>
  
  <p>If parsing is done by webpage, should the SW cache html texts?</p>
