Best practice for instant claim of a page by Service Worker

由 帅比萌擦擦* 提交于 2019-12-14 01:45:24
问题 I currently have a service worker set up to claim the page immediately, due to the nature of the application and user experience. As this application is converting over from AppCache, which had a dynamic Manifest file created for each user, I found that the best method was to Parse this Manifest file to a JSON array and send it to the Service Worker in order to cache it. The problem being I need to wait until the Service Worker is active before it can receive this array. I currently have set

Angular 5 Service worker not working / Doesn't cache background-image

由 百般思念 提交于 2019-12-13 13:33:34
问题 I'm having trouble getting my angular5 service worker to work. I have two main problems: The service worker doesn't cache assets images that are used as background-images After simulating a network disconnect the service worker initially pulls files from the cache (except the the aforementioned non cached files), but after a second refresh it runs into an error. Below is a more detailed report of my problem. You can follow along by cloning a repo I made to highlight this problem located here.

The problem is whenever I make any changes to the views or the js file it won't get reflected after deploying the new WAR file without clearing cache and doing a hard

Is it possible to combine a dom-repeat on a platinum service worker?

由 亡梦爱人 提交于 2019-12-13 04:44:45
问题 I want to provide a user the ability to cache up to 2,600+ items, by groupings (categories of book, individual books, or possibly even just chapters of a certain book if they don't want the whole book). It is not possible, as far as I can tell, to precache all of these items because there are 2,600+ of them, and will be more in the future - the service worker will timeout with under a couple hundred. And since service workers either get all or none on install (if I understand correctly), do I
