Progressive Web App (PWA) version

[dandv]

Any thoughts on developing Laverna as a Progressive Web App, instead of spreading efforts across native Android and iOS apps, that (will) come with their own bugs (e.g. #478)?

Making Laverna a PWA would involve registering a service worker - pretty simple. From there on, the following capabilities become available:

• working offline (the service worker can intercept any requests from the page, and serve cached results)
• adding a Laverna icon to the user's home screen
• sending push notifications
• having links to individual notes that the user can bookmark

There will also no need to constantly push updates to the Play Store, because the service worker can fetch the latest JS from the server.

PWAs already work in Chrome, Firefox and Opera, with Edge slated to implement service worker, and Safari considering it. But even without service worker, on Safari the user can already add the web app to the home screen.

Another popular app that started a PWA version after seeing the above advantages is Rocket.Chat, a Slack alternative.
