298992 โ€“ Pan gestures pass through scroll containers laid over vertical-rl body text (but only once the document's scrollingElement has been scrolled by about one viewport of width)

Bug filed here! Thanks for the push.

It's even worse on the latest releases of Safari. The scroll container doesn't even render! Wasn't expecting that.

macOS Tahoe 26.0 (25A353):
- Left: Safari 26.0 (21622.1.22.11.14).
- Middle: Safari on iOS 26.0.
- Right: Safari TP 227 (WebKit 21623.1.5).

Linking this as well.

It seems it doesn't require a mix of horizontal-tb and vertical-rl. Purely vertical-rl is enough. Will link this video in the Bugzilla report.

I think I've got a repro! Both a scrolling issue (as the pan gesture passes straight through the overlay) and a rendering issue (as the bottom portion of the overlay unexpectedly goes black).

Just cleaning it up, then will file it.

@smfr.bsky.social did offer to raise visibility โ€“ I just hadn't had any time to try to make a repro, sorry! I'm trying to make a repro now, just failing to work out the exact combination of factors behind the ebook that was causing the issue.

This is another big deal. We can write React Native modules in Rust now, with a standard approach rather than deep, specialist expertise.

Heck, we can code in C, C++, C#, Swift, Zig, Go, too โ€“ pick whichever you feel most comfortable in!

This is it, the most consequential evolution of React Native since JSI and New Arch. Through Node-API, we can:

- unit-test native modules in Node.js
- code-share with Electron
- use NativeScript inside React Native
- prebuild community modules
- achieve 7-second app builds

Merge pull request #1 from shirakaba/source-assets ยท shirakaba/paranovel-two@16fc303 support "source assets" to improve DX of injecting scripts into the WebView

See this PR in which I set up Metro to special-case certain file extensions.

I transpile .wvts files from TS to JS, then wrap in a string (to inject into a WebView).

In your case, youโ€™d transpile .purs files to JS ESM modules, without wrapping in a string afterwards.

The number of people who didnโ€™t even bother reading Anders and Ryanโ€™s summaries of how the language evaluation went, and just parrot bastardised takes by lazy influencers, is just aggravating

I've just uploaded the lightning talk I gave on build profiling at React Native Meetup #20 (featuring Meta and Callstack) on Feb 18th.

Now streaming! We're going to be recreating the Xcode UI as a React DOM + Tailwind component for teaching purposes.

In this screenshot, the top bit is what I've completed so far, while the bottom bit is the reference image that we need to reproduce!

More progress on my Xcode classroom โ€“ a React DOM + Tailwind v4 component for making tutorials that involve Xcode!

Lately I've been improving window resizing. I wanted to match how Xcode collapses labels (yet not icons) when space is limited. Keep your eyes on the run destination!

my understanding is that you are also not allowed to just write css anymore and you have to use some sort of meteorological phenomenon to manage it for you

Whoops, obviously forgot to rename "compendium" -> "paranovel" for the screenshot.

Well, there's plenty of other glaring errors in there anyway ๐Ÿ˜…

Continuing work on my fake in-browser Xcode mockup for making React Native tutorials. Spot the difference!

Built using React DOM and Tailwind v4. I can't use SFSymbols due to licensing, so I'm doing the best I can with Material Icons/Symbols ๐Ÿ˜… it somewhat works!

I've been making a docs site to share everything I've learned as a fullstack dev. ๐Ÿ“œ

When it came to documenting React Native, I decided that instead of using static screenshots of Xcode, it would be nice to have an interactive mockup of Xcode in-browser. So I began making one!

Speeding up the JavaScript ecosystem - Rust and JavaScript Plugins Up until recently, supporting JavaScript in Rust based tools has been deemed not worth it. The main concern is the overhead of the de-/serialization cost when sending data back and forth. But there is...

Very cool, and great writing as always. Iโ€™ve heard this โ€œarrays, not treesโ€ sentiment for AST-traversal come up a few times in the last couple years.

I heard on the Devtools podcast that Tailwind and/or VoidZero (canโ€™t recall) are investigating the same. The idea came up on Hacker News too.

Unfortunately the patching necessary to implement Expo support for react-native-macos and react-native-windows is not very talk-friendly and the content would quickly go out of date, so mmm it's a hard one.

React Native is responsible for most of the Ruby, Swift, Objective-C and C++ learning Iโ€™ve ended up doing.

There are certainly many products that can be built just in JS land with off-the-shelf native modules, but to be truly unlimited, an RN dev should definitely be ready to dive into native code.
