service-worker

问题 I have a site with a Service Worker that caches some static resources on install. Some other resources are not cached, like data requests. So if you test the site using offline mode in Chrome, most of the page is properly displayed, but data is not there, and some errors appear in the console because of those failed requests. All right so far. But then I've created a test with Selenium and Chromedriver. I load that site, I visit the home page, Service Worker is properly installed, and then I

问题 To get history mode working with Vue-Router you need to return the contents of your main page when trying to access a route that doesn't exist. For example when you visit mypwa.com/route1 your server checks if there is a resource at route1 and if there isn't, it returns the contents that is found at mypwa.com/ (but without redirecting you). This is great and works when you're online, but it requires your server to do the actual re-routing. If you have a PWA that's meant to work offline, you

问题 Following This Discussion, Where there is a comment that speaks of patching a Fetch by overriding self.fetch, self.XMLHttpRequest, and self.caches (for cache.add/addAll)? It would seem these would let you intercept network requests and manipulate responses before the main SW script sees them. I have been looking out for any documentation that speaks of such stuff, and can not seem to find any. In a scenario where I simply need multiple service workers to co exist in a single scope, After

问题 When you visit this web site https://bugs.stringmanolo.ga/index.html, while navigating around the main.js file is calling a method from ff.js file to cache a good amount of the resources. So next time you land to the web the files are directly taken from your browser cache without make any request. This means if you visited my website before, you can load it again without internet conection. The problem is, this only works if you directly time the index.html file in the addressbar. Lame. Thid

问题 I hava a pwa with this sw.js: const info = "versione: 1.0.0 data: 07-01-2020 12:46"; const CACHE = "pwa-offline"; const pages = [ // some files ]; self.addEventListener("install", function (event) { //console.log("Install Event processing"); self.skipWaiting(); event.waitUntil( caches.open(CACHE).then(function (cache) { //console.log("Cached offline page during install"); return cache.addAll(pages); }) ); }); self.addEventListener("activate", (event) => { }); self.addEventListener("fetch",

问题 I'm building a PWA that on Android uses Push Notifications to receive alerts. Of course, Safari/iOS doesn't support Push Notifications, so I need to implement an equivalent. Can I have my Service Worker poll for data, either using http long timeouts or socket.io? On receiving an alert, the SW will focus/create an app window to then deal with the UX. If there is a list of cans & can'ts or dos * don'ts for service workers, that would be great. 回答1: No, that is not possible. You cannot keep the

问题 I wanna implement push notification for my website: Consider we have a shopping site, whenever a user click on one product, the server should push notification to the owner of the product that user (for example John) wants to buy your shoe. (real-time). I have read some articles about web worker (like socket.io) and service workers, I conclude that service workers are the best choice. Am I true? How can I implement that push notification? 回答1: A Service Worker is a special kind of Web Workers
