title: Excluding analytics.js and fbevents.js from Service Worker
body: <p>Is there a possibility to exclude fetching Google Analytics, Google Tag Manager and Facebook Pixel scripts via Service Worker in PWA?</p>
  
  <p>From what I found out today - Facebook Pixel Helper and Google Tag Assistant return errors after reload if a website uses Service Workers. I'm not entierly sure if the data is not sent though (Chrome Dev Tools show that request to Facebook and Google is beeing sent with code 200). </p>
  
  <p>It looks like both scripts fire on the first visit but won't fire on reload. I have no programming experience and have a vague notion of how Service Workers work but I need to make sure that I get all the data correctly because I'm an analyst. Can anyone point me to the right direction? </p>
