问题 I have a SSR based react app and at present implementing Workbox tools for precaching and offline capabilities into it. I ran into issues mainly because the site relies on cookies at server side and issues redirects based on these. Initial load works fine, but once service worker(sw) is online and another refresh results in sw doing a fetch call with the url from within workbox source. During this time, the server doesn't find cookies(fetch doesn't carry credentials - link) and issues a

问题 I have a service worker. Here's the install event: self.addEventListener('install', function (event) { console.log('Installing Service Worker ...', event); return self.skipWaiting() .then(() => caches.open(CACHE_STATIC_NAME)) .then(function (cache) { return cache.addAll([ './file1.html', './file2.html' ]) }) }); For some reason, when I edit the service worker code and update the query parameter in the service worker file URL, it installs but does not activate (according to Chrome DevTools) —

问题 Is it possible to read from local storage and track geolocation in PWAs with a service worker while app is not open on phone (in background) So far my research is pointing to no, and I am finding that the PWA needs to be open for location services.
