PWA are a hot topic and it is important to understand that they are a different approach to apps than the traditional way of packaging something and letting the user install it. In this keynote you'll see some of the differences.

8. “But, what is a PWA?”,
I hear you ask.
Yeah, OK, a developer can dream…

9. A PWA is
Discoverable Installable Linkable
Network
Independent
Safe Re-engageable
Progressive Responsive App-Like Fresh

10. Asking that much is a bit
of a stretch…

11. Let’s make this simpler…
A PWA is a web-technology
based application. It mixes the
best of the web and the app
space.

12. Let’s make this simpler…
A PWA has a unique URL. This
can be used as a distribution
model. The link.

13. Let’s make this simpler…
PWAs are progressive.
They don’t work and behave
the same everywhere.

14. Let’s make this simpler…
PWAs are progressive.
They improve over time and
with the ability of the host
environment.

15. Let’s make this simpler…
If you choose to install PWAs
they behave like we expect
apps to behave. Without any
of the annoying bits…

16. Bridging the gap between
apps and web needed
good technology

17. PWAs use the
current web,
progressively
aka.ms/webcando

18. Additionally, we needed
two new technologies.

19. Web
Manifest

20. Service
Workers

21. We talk far too much

47. PWA tooling is great!
(as always, it is tough to build tools for an open stack)

60. It is tough to find
PWAs on FIRE
(that aren’t demos)

61. PWA Stats
(Cloud Four)
aka.ms/pwa-stats

62. ▪ Web App Manifests should suggest quality:
we found 1.5 million manifests across 800k
domains. Most are not ready. We will be
looking for non-boilerplate manifests that
include a name, description, and at least
one icon that is larger than 512px square.
▪ Sites should be secure (“HTTPS”)
▪ Service Workers should be an
enhancement: we expect experiences to
degrade gracefully if Service Worker is
unsupported.
▪ Sites should consider automated testing for
quality.
▪ PWAs must be compliant with Microsoft
Store policies:
PWA need to be
high quality
