Pretty big deal for PWA. Now we can send push notifications, and update app badges.

Now if we could get periodic background sync api, and vibration api, that would be perfect.

Only for web pages that user has manually added to the home screen. Since normal users don't even know what that is, I don't see this as pushing the PWA envelope forward.

This is one of the integral features that prevented a lot of places from even creating PWAs. Now that it no longer exists as a problem, PWA adoption will increase and alongside it education. For example, many places are probably going to show a "add to home screen" banner, with related icons to make it easy for people to find where that setting is. Kind of like how many "normal users" in the past would have been scared about downloading a new browser, but now when you download a new browser it shows you the next steps on how to do so (most of us don't even think about these anymore, but they exist and are important).

A next major step is inclusion into the app store, but until then this is a major win for PWA.

> PWA adoption will increase

This is the 2020ies' "year of the Linux Desktop", right?

I tested some features on my PWAs.

New wake lock API does not work in PWA, only works in Safari...

Apple is making sure that nobody will use PWAs.

https://whatpwacando.today/wake-lock

The release notes for 16.4 include "Added Support for the Screen Wake Lock API"

https://developer.apple.com/documentation/safari-release-not...

Yeah, but "bugs" happen and this new wake lock only works in browser safari.

Does NOT work in PWA. Bug or intentional road block?

It does not work for me in browser Safari (iOS) either:

undefined is not an object (evaluating 'navigator.wakeLock.request')

Update: Turns out it's only available behind HTTPS. The PWA bug might be related.

I'd love to know if anyone discovers what is goin on with PWAs. I got wake lock working in the browser but not with the PWA.

> Apple is making sure that nobody will use PWAs.

Ah yes. The amount of random APIs that are an absolute necessity for something to be called the true PWA just keeps growing with every release.

Not really

If there is a bug, we will fix it. Bugs can be reported at https://bugs.webkit.org. We would never intentionally prevent web technology from working when a site is added to the Home Screen and opened as a web app.

Thanks!

Thanks for posting the bug links.

Also wanted to point out that the user feedback in https://bugs.webkit.org/show_bug.cgi?id=249645 is not the way we should treat browser developers. (Not blaming the parent - I assume this is some other user being..... cranky?)

Notification from WebPush does not play alert sound
