Our team just finished creating an Ionic Application with the intent of using it as a PWA and not having to bother with putting it on any App Store. We want our users to be able to use the app while disconnected, create entities inside the app which save to IndexedDB and then persist to the server when connection is made. Right now all of this works flawlessly on a laptop or desktop. The app also works fine when added to the home screen, as long as you have internet. But when the mobile device does not have connection, you obviously just get a disconnected browser message. Is there any way to include the app files into an app cache using config.xml? Is this even possible at the current point in time?
