One of the final bosses for oxlint to implement is typescript-eslint/member-ordering. It handles how methods, fields, and other members are ordered inside classes, types, and interfaces.
An implementation was attempted with Codex but it seems the iceberg was deeper than expected

For web developers on Mac, good news! Safari is adding an MCP server so your agent can easily test, preview, and debug web content with @webkit. For example, @claude can now see what it's building without needing Playwright or other tools. More here: webkit.org/blog/18136/introd…

npx expo-desktop create-app scaffolds iOS, Android, macOS, and Windows in one shot, pod install included.
Watch @birch_js's talk on why @expo reaching desktop could pull more React Native devs away from Electron on Mac and Windows👇 youtube.com/watch?v=D4yUa0-w…

Even in the age of agentic coding, if you have three platforms to target, I think you'd be mad not to use a cross-platform framework.
It allows you to focus your time (and tokens!) on a single abstraction to raise the quality bar for all of your platforms.
> first class desktop experience
looks inside
> it's vibecoded electron slop
can't even be bothered to vibecode native apps, smh. i thought you were on self-improving recursive loops, what went wrong.

My App.js Conf talk just got uploaded 🥳
It introduces my new library for setting up an Expo project to target both mobile and desktop.
Since the talk, I have been working on Expo Prebuild support, so that you can use Continuous Native Generation with desktop platforms as well!

Don't use computed properties to split a large View 🙅🏽♀️🙅🏻♂️
This an official bad practice written by Apple in Xcode 27 coding skills

12 years ago in Bulgaria, Telerik created a proof-of-concept NativeScript for Universal Windows Platform, to go after the emerging Windows Phone market.
Sadly, Windows Phone was a commercial failure so the project was sunset, but Osei’s here to push it over the line for desktop!
I finally got the chance to finish up my work on the @NativeScript Windows Runtime also added support for WinUI3 inside of Core. We plan to add desktop support in the next major 😇. So yes @windowsdev support for all
I created a demo app for anyone wanting to give it a try 👇

I’m trying to make the best git / diff / PR review app for macOS. It’s already FAST AF 🔥
30MB, low memory usage, loads any repo instantly, full syntax highlighting. Using React Native macOS for the best performance.
v1 coming soon!
What would make this the best app for your?

(actually, there's thousands of lines to delete still, as I haven't done the cleanup pass yet to remove my previous approach that leaned on Expo CLI, but the point is – it's a big feature and a lot of work)

56 files changed, 6101 insertions(+), 553 deletions(-).
That's how much extra code I've had to port, to fully implement Expo Prebuild for macOS and Windows in Expo Desktop.
Can finally proceed to the testing phase! 👨🔬

I just added support for inline native modules on react-native-macos in Expo Desktop 🫡
Expo SDK 56 is out 🙌
◆ Expo UI is stable on iOS and Android
◆ iOS builds 16% faster, plus another 20% on EAS from precompiled community libs
◆ Android cold starts 40% faster
◆ Expo Router decoupled from React Navigation
◆ Inline native modules: write Swift and Kotlin right next to your TypeScript
◆ Hermes v1 by default
◆ Bytecode diffing on by default (~58% smaller OTA updates)
◆ iOS Widgets stable
◆ React Native 0.85 + React 19.2
It's been two months since SDK 55, and we packed in everything we could fit. Your iOS build times are going to thank you. Full changelog ↓

I'm so happy that SwiftUI in iOS 27 supports granular text selection! We can just apply the existing textSelection() modifier to a Text view, and instead of selecting the entire text block like in iOS 26, it lets users select a portion of the text with the standard drag gesture.
ALT Side-by-side comparison of text selection in a SwiftUI app. iOS 26 selects the entire text block, while iOS 27 allows selecting individual words or portions of text with the standard drag gesture. A SwiftUI code snippet using textSelection(.enabled) is shown on the left.
