Replies for: Hi, I just followed your guide but it did not work. Maybe my chrome does not support service worker? I am working with this: Version 80.0.3987.122 ...

Hi Lizzy, what does the chrome console say?

Lizzy Mendivil • Feb 28 '20

I added this:
if ("serviceWorker" in navigator) {
in serviceWorker.js file
So it never enters into the conditional

Please try the code as from the tutorial:

// serviceWorker.js
import { Meteor } from 'meteor/meteor'

Meteor.startup(() => {
  navigator.serviceWorker
    .register('/sw.js')
    .then(() => console.info('service worker registered'))
    .catch(error => { 
      console.log('ServiceWorker registration failed: ', error)
    })
})

does it throw an Error? If so, could you please show me the error stack?

Hm there seems to be no service worker in navigator. Is this a private session or do you block all cookies? I think there were some sw issues at least in Firefox that were related to these.
