service worker - navigator.serviceWorker is never ready -


i registered service worker successfully, code

navigator.serviceworker.ready.then(function(serviceworkerregistration) {     // have push message subscription?     ....

hangs -- function never called. why?

the problem service-worker.js file stored in assets sub-directory.

don't that: store service-worker.js in root of app (or higher). way app can access service-worker.

see html5rocks article --

one subtlety register method location of service worker file. you'll notice in case service worker file @ root of domain. means service worker's scope entire origin. in other words, service worker receive fetch events on domain. if register service worker file @ /example/sw.js, service worker see fetch events pages url starts /example/ (i.e. /example/page1/, /example/page2/).

added

a new problem serviceworker never ready if page hard-reloaded. subsequent soft page reloads work fine. google's own sample code fails. see chrome bug report.

the bug fix included chrome 44.
