Progressive Web App demo for a presentation given at DrupalCamp Krasnodar 2017.
You may look at the application in action here: kkomelin.github.io/pwa-demo.
Briefly, what it can:
-
It works offline. When you're online and load it first time, it caches all resources except the Druplicon image. When you load it being offline, it loads resources from cache, so that it's almost the same app, except the Druplicon image, which is replaced with an offline image.
-
You can pin it to your home screen through Chrome on Android or to your desktop through Chrome on Ubuntu. Chrome will actually advise you to do so if you visit the app at least twice, with at least five minutes between visits.
