sw-registration.js is fingerprinted incorrectly when rootURL is set.

I am trying to setup service workers for an ember 3.4 app. The app is served from a sub directory ‘/mobile/’ so the config/environment.js rootURL is set to ‘/mobile/’.

In development the sw-registration.js script is added to the index.html page and mobile is prepended. However when deployed via ember-cli-deploy the sw-registration.js is fingerprinted and a incorrect ‘/mobile/’ path is added. (I say incorrect because all other assets are not prefixed by a mobile path).

All assets are fingerprinted and served from a cdn. I am unsure how or if the app should fingerprint the sw-registration.js file.

Thanks @martndemus for the suggestion. I started to refactor the add-on to omit the rootURL from the sw-registration.js src if the fingerprint prepend option is present. But because _getRootURL() function is used by the sw.js file as well, so I punted.

It turns out there is a config option that handles this better any how. By using the inline registrationStrategy we don’t have to worry about the rootURL being appended to the fingerprint.prepend string.

    //ember-cli-build.js
    'ember-service-worker': {
      registrationStrategy: 'inline'
    }
