A nice overview of the Payment Request API, which is getting more and more browser support.
Andrew picks out his favourite bits from this year’s Google I/O, covering web payments, CSS containment, and—of course—Service Workers and progressive web apps, although he does note (and I concur):
I wish Google would focus as much attention on ‘normal’ sites that perform navigations as they do on so called ‘app-shell’ (which is just a new name for single-page apps, as far as I can tell), but then many people will be building SPAs and these recipes will make those apps fly. In news publishing we seem to flip flop between traditional page navigations and SPAs, but I’ve never found a SPA news site (or a native app) that I really like more than a normal website. Maybe a really good progressive web app will change that. But I’m not convinced.
Still, as he says:
All this really just underscores how flexible ServiceWorker is and that with it we can disagree on what the right solution is, but we can all get what we want anyway.
PayPal moves into the territory of merchant accounts. With an API no less!
