One of the smaller (but big for webdevs) announcements from yesterday’s WWDC keynote was Web Push coming to Safari. It’s built on three web standards all working together. What does it do, well it enables websites to “notify their users of time-sensitive or high-priority events, even if the user does not currently have the site open.”

As long as you’ve coded your web application to the standards you will be able to reach Safari 16 users on macOS Ventura. You don’t need to join the Apple Developer Program to send Web Push notifications.

That’s good news, but is this feature something users want? I can think of zero websites that I’ve allowed to send me notifications even when Safari is open, let alone when I’m not even browsing the web.

Jen Simmons posted a nice thread on Twitter alongside the announcement and fielded many people’s questions/concerns along the way.

Safari 15.4 dropped today and it has a bunch of goodies in there for web devs including lazy-loading images, the <dialog> element, the :has(), pseudo-class, and more.

With the release of Safari 15 for macOS Monterey, iPadOS 15, iOS 15, and watchOS, as well as macOS Big Sur and macOS Catalina, WebKit brings significant advancements in privacy and security, improved interoperability, and a host of new features for web developers. Take a look.

We discussed a few of these in-depth on JS Party #195, but at the time I was referencing the beta features announcement and it was 404ing during the show. This is a much better resource.

Workers will be at your service in an upcoming release of Safari — specifically Safari Technology Preview 48, macOS High Sierra 10.13.4 and iOS 11.3 beta seed 2.

While WebKit’s implementation and feature set is quickly evolving, we believe it has reached an important milestone in terms of functionality and compliance: applications using service workers for offline support or network/cache optimizations run successfully on latest WebKit builds. Let’s now dive into the specifics…
