We built a PWA with vanilla javascript that does a lot of augmented reality work with the camera. The main issue is the lack of iOS support. Apple recently updated iOS to include support for the service worker (literally like this week) but it still lacks a huge number of features that chrome on Android has and basically every desktop browser has.

You do get access to a lot of the core sensors on the device but the inconsistencies on iOS just really make life a lot harder. Hopefully this will change over the next year but I'm not sure how quickly it will happen. So basically yes, you should build PWAs but until apple gets completely on board you can't really leverage them to their full extent like you can with chrome on android.

ios supports PWAs (service workers) now doesn't it?

[michaelgreen]

Yeah they added it in the most recent version of iOS (11.3) but progressive web apps have a very loose definition the most basic of which is, as you correctly stated, using a service worker. However service workers are just the ground floor of a much bigger building of features that should be able to be leveraged cross browsers.

Yes, just released in 11.3
