Here’s a good reason why you may want to reach for plain HTML first: mohkohn.co.uk/writing/html...

Out-of-order streaming HTML is coming to a browser near you! This means you can stream HTML to the browser in any order, which enables web apps to send the most important HTML first, regardless of where it is in the document. This is huuuuuge! 🧵1/3

I don’t think HTML-in-canvas is the biggest revolution in HTML right now. I think another feature is. One that will be truly revolutionary and that will have cross-browser support very soon. Details in tomorrow’s edition of Modern Web Weekly. Subscribe link 👇

Your web app can read and write files on the user’s device and request persistent storage so it’ll never lose data again, even if it’s not used for a while. Check the details in Modernn Web Weekly 73 Subscribe link 👇

Don't wait for iOS support to make your PWA installable. If we can teach users 4 clicks to add a web app to their favorites, we can teach them how to install a web app. Users are not unfamiliar with PWAs because of the lack of iOS support. It's because we don't build enough of them. 🧵 1/2

Firefox 151 now support the Document Picture-in-Picture API that enables web apps to open an always on top window that can be populated with arbitrary HTML content. Details in the upcoming edition of Modern Web Weekly. Demo and subscribe link 👇 🧵1/3

I just published Modern Web Weekly #71 🎉 This edition is all about the WebAuthn PRF extension which enables web apps to derive encryption keys using the user's passkey. This means your web app no longer needs to store a private key in localStorage or IndexedDB. Demo and subscribe link 🧵1/3

It sucks that it's so difficult to install a PWA on iOS. It sucks that support for PWAs on iOS is limited. But we can't wait for Apple to improve this before we start building great web apps. When users perceive web apps as not as good as native apps, it's not always about the... 1/4 🧵

If you have a web app that doesn’t even work offline, you have no business complaining about PWA limitations. Use what’s available.

Progressive web apps (PWA) are disruptive because they eliminate gatekeepers like Apple and Google that basically determine if your business becomes a success or not. If you're not in the app stores or they kick you out, tough luck. PWAs change that. That's my mission.

Jean-Jacques Dubray built a very nice PWA for his restaurant. I'm proud What PWA Can Do Today was helpful in building it! Great work Jean-Jacques! www.linkedin.com/posts/jdubra...

OWA has been singularly effective in winning letter-of-the-law chamge, and the action now lies with regulators. They meed reasons to believe *enforcing* the law is worth the effort, and your voice can make a difference. Read @open-web-advocacy.org's roundup to learn about the fights that matter:

A bit of a vulnerable post by me but we need your help to get us through what has been a more difficult period than 2020. It would be really appreciated if you could read and share in your networks too 💛 bell.bz/its-been-a-v...

From Chrome 142, you can use range syntax in style queries. I created a demo of a slider with changing background color based on its progress value using range syntax and if(). Demo link in the first comment 👇

The Web Install API is very promising and even enables web apps to install other web apps. Check the demo: whatpwacando.today/installation

How's the mobile CPU landscape evolving? Thanks to process node improvements, a mid-range Android from 2025 is (finally!) as fast as 2017's iPhone 8, but a low-end (~$100) smartphone isn't yet as speedy as a decade-old iPhone 6s.

We don't need to wait for better PWA support on iOS to make web apps a success medium.com/gitconnected...

Lit is great 🔥

What do we need to do to make web apps a success? Here's my vision: medium.com/@dannymoerke...

I can’t even begin to explain how utterly useless the Google Cloud Translation API is on web dev docs that are translated to Dutch. It literally translates all technical English terms that we use verbatim to Dutch. It’s comical at best.

TIL when an iOS device is connected to a macBook, click the inspect tool icon in Safari Web Inspector, then tap an element on the screen, the Elements panel reveals that element. I always thought it was a useless tool since the screen doesn't show the iPhone screen, but now I know how it works!

I added a demo to What PWA Can Do Today to demonstrate how the viewport meta tag configures how the on-screen keyboard resizes the viewport. Supported in Chrome on Android and coming soon to Safari. I explain this in the upcoming edition of Modern Web Weekly. Subscription link and demo 👇 🧵1/3

Like @bram.us already mentioned, viewport behaviour in Safari 26 is broken. It seems safe-area-inset-* no longer works and the on-screen keyboard makes matters worse. Here's a screen recording of Safari and a PWA. First Safari: 🧵1/2

Hallelujah! In Safari 26 on macOS Tahoe, you can now finally inspect the service worker of a remotely connected iOS device 🎉🎉🎉

PWAs can capture links, but support is fragmented across OSes and platforms. I tested all platforms and wrote about my findings in my new article "The state of link capturing in PWAs" Read if for free on Medium 👇
