问题 I am trying to make my website as PWA and got the ServiceWorker integrated into it. The ServiceWorker is registered properly as I am able to see the "offline" capabilities.

I have also opened a Github issue for the same which has more details and screenshots: https://github.com/pwa-builder/pwa-install/issues

问题 I was running through FCM documentation and - I would like to understand about what would happen when the subscribers come online after a longer offline period. - Will FCM store all the push notifications received during the offline period - Will FCM deliver all the messages once the subscribers have come online 回答1: If the device is not connected to FCM, the message is stored until a connection is established (again respecting the collapse key rules). When a connection is established, FCM

问题 Quick question: I have a service worker that caches a page from subdomain "domainB.project.company.com" Expl: domainB.project.company.com/mypage.html This works, I can see the assets + html being cached in my Chrome Dev Tools. Then I have another subdomain "domainA.project.company.com" with a page domainA.project.company.com/hello.html so, both pages have the same host... Now: the mypage.html is fully cached. Why - when offline - isn't the "mypage.html" shown when navigating to that url from

问题 I have PWA and I can run it as standalone (if user clicks icon on a device) or I can run as normal website (if user enter URL directly into web browser). Is it possible to redirect page (open as standalone) if user open it as non standalone?

By clicking the icon on the device (meaning you already installed

问题 Imagine we have N assets that need to be pre-cached with a service-worker once user navigated to the web site. We have appropriate precache-manifest.js with listed N-files and we are using workbox.precaching.precacheAndRoute([...]) to configure needed behavior (default CRA setup) Is there a way to keep track of precaching progress when using workbox.precaching.precacheAndRoute or workbox.precaching.precache? I imagine it could be something like passing a parameter-callback function to the
