问题 My question is, Is it possible for the Users to acquire these changes without having to REINSTALL the PWA application? I have a PWA application deployed in Production. The client already installed the deployed PWA application in their MOBILE devices and I want to DEPLOY another patch of updates in the PWA application in the HTTP server. 回答1: Another simple way to update application is using workbox-window. You can detect updates in PWA and restart your application to get the last updates. For

问题 I have a working google app script web app and trying to migrate it as a progressive web app. I googled but found no documents on how to do it. I found a link describing how to migrate a web app into a progressive one in the fallowing link (on the google site): Migrate Your Site to Progressive Web App I started applying the steps but, when it comes to change the default manifest file (appsscript.json) I got an error like "Invalid manifest:unknown property name ". The original manifest content

问题 I have converted a single page HTML5 Cordova app into a PWA. The app uses jPlayer extensively to play mp3 files. I am using a variant of the circular jPlayer here: http://jplayer.org/latest/demo-05/. The circle player has a circular progress bar that can also be used to scrub backwards and forwards through the track. Everything works fine in PWA mode until I cache the mp3 with Workbox (version 4.3.1). Then scrubbing fails. I can grab the scrub bar and move it but when I release it the track

问题 Push subscription has unsubscribed or expired, with statusCode 410 , in less then 24 hours. I'm using web-push to send notifications with fcm-endpoint & vapidDetails.

问题 This is an architectural question. I haven't implemented FCM yet, but as far as I understand someone needs to deploy an XMPP server in a real world scenario which provisions the inventory of the registered device tokens. In my use case I'd like to just broadcast short messages about important update information, like "XY presenter's session at 15:00 got cancelled" and I'm not interested in the device tokens. My application is a Progressive Web App, so I would use FCM for Web. The demos I saw

问题 I'm using TrustedWebActivities and I'm getting an immediate app crash on Samsung S8, S9, and Pixel 2 devices with the below Exception. Some research suggests that this might happen on devices where there's an older version of Chrome installed which doesn't support TWA and the fall-back method fails. But I've confirmed that the Chrome version is 71 (also, this works on Samsung S7, Pixel 3). java.lang.NullPointerException: at android.support.customtabs.TrustedWebUtils.launchAsTrustedWebActivity

问题 I am new to Xamarin and I have successfully created an application in Xamarin for iOS. What I need is a way for this application to be viewed in the browser as a PWA. I figured to learn xamarin because I thought that this was a useful resource. I have looked in to ooui but I can't successfully attach my Xamarin project to ooui. At the end of this project I will have a running PWA coded in c# for iOS in the browser. A link to the Xamarin can be found here: https://github.com/SunRhythms

问题 Trying to solve the problem referenced in this article: https://philna.sh/blog/2018/10/23/service-workers-beware-safaris-range-request/ and here: PWA - cached video will not play in Mobile Safari (11.4) The root problem is that we aren't able to show videos on Safari. The article says it has the fix for the issue but seems to cause another problem on Chrome. A difference in our solution is that we aren't using caching. Currently we just want to pass through the request in our service worker.
