问题 I've started with PWA, I want to add home screen icon to my app, but it's added to apps menu instead of home screen 回答1: It's usually added to BOTH app and home screen.

问题 I have created a PWA using Angular guidelines. I am facing problem intercepting the app install banner. I am using this code to defer it to a later point: let deferredPrompt; window.addEventListener('beforeinstallprompt', (e) => { // Prevent Chrome 67 and earlier from automatically showing the prompt e.preventDefault(); // Stash the event so it can be triggered later. deferredPrompt = e; console.log("Intercepting the app install banner prompt"); setTimeout(function() { deferredPrompt.prompt()

I am linkin it in my html like this: <link rel="manifest" href="/manifest.json"> The manifest looks as following: { "short_name": "Tabbs Web App", "name":

问题 I wrote a simple PWA (current version) based on this tutorial by Vaadin. It works fine, tested in Chrome, also in offline mode. By using it on a mobile device, issues occur: After saving the PWA, starting it once, it runs fine. then after closing, turning on flight mode and restarting the PWA, I get a system message, saying I have no internet connection -> no problem, I can ignore that after ignoring, the app does not load the static assets as I expected it, but shows a blank page, saying the

问题 I am new to PWA and have been testing my PWA project using firebase console database. When offline, I have code to save my post data in indexedDB when i submit my post data to saved later when there is WiFi(online). It did save the data in indexedDB when no WiFi found, but when i turn on my WiFi, it doesn't post my data in realtime.

问题 In an Angular PWA I would like to redirect the user to a custom offline page (offline.html) if there is no internet connection available. Using the ng-sw.config.json file I setup the assets and APIs to be cached and which strategy to use (performance/freshness) and I could serve the application even when offline without any problems.
