The slides from Calum’s presentation about progressive web apps. There are links throughout to some handy resources.
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.
Outlining the architectural thinking required to create what the Google devrel folks are calling progressive apps.
Browsers without service worker support should always be served a fall-back experience. In our demo, we fall back to basic static server-side rendering…
…but this is only one of many options.
Hmmm. In my opinion, sending usable HTML on first request isn’t an implementation detail—it’s crucial. But on the whole, this approach is very sensible indeed.
