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 – 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 · 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, you’d transpile .purs files to JS ESM modules, without wrapping in a string afterwards.

The number of people who didn’t even bother reading Anders and Ryan’s summaries of how the language evaluation went, and just parrot bastardised takes by lazy influencers, is just aggravating

DMed! 🥳

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

Someone should really look into the cmake settings for Android!

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 – 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 😅

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 😅 it somewhat works!

I've been making a docs site to share everything I've learned as a fullstack dev. 📜

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...

Speeding up the JavaScript ecosystem part 11 is here! This time we're looking at:

Extending Rust tools with JavaScript plugins

Very cool, and great writing as always. I’ve heard this “arrays, not trees” 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 (can’t recall) are investigating the same. The idea came up on Hacker News too.

Helping bring Node-API to React Native 🫡

Join us, you'll never have time to spare for language-learning ever again haha

Just successfully built a Node-API module for iOS, tvOS, visionOS, and macOS (with and without Catalyst), all packaged into a single XCFramework 🥹

Had to dig through the cmake internals to figure out how to build for Catalyst properly, but got there in the end! 😮‍💨

Yeeep

I think the talks aren't streamed or recorded, but I'll make the slides available online afterwards.

There are still some spots available however, so please attend if you can make it!

まだ空きがありますので、お時間があれば、ぜひご参加ください！

トークは配信も録画もされないと思いますが、後ほどスライドをオンラインで公開いたします。

Thank you!

Thank you! It's certainly on my mind! Just a bit overloaded with other stuff lately 😅

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.

We just annouced the React Native app I've been working on!

noman is an app for transcribing meetings, capturing audio from any video conferencing software (on desktop).

It might be the first Expo app in the world to target iOS, Android, macOS, and Windows?

React Native is responsible for most of the Ruby, Swift, Objective-C and C++ learning I’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.

I've started writing a docs website to share all the knowledge I've learned over nearly a decade of working with various technologies such as React Native.

As Docusaurus makes it so easy to set up (🙇‍♂️ @sebastienlorber.com), I've decided to provide screenshots in both light-mode and dark-mode!

Challenge:

Start a clock. Look for where the React Native CLI starter template lives (let's say the TypeScript one). Stop the clock. Tell me how long it took you to find it.

Ohh yeah. Can now start to run your GitHub Actions CI builds on arm64-based Ubuntu machines.

It says they're faster than previous Arm-based VMs, but mainly I'll be interested in whether they're faster than x64!

I've not filed any bugs yet (usually too exhausted to invest any deeper), but here's the other show-stopper I ran into:

I'll try to file both!
