🖤❤️ RNR 363 ❤️🖤 AI coding tools are moving fast 👀 This week: @robinheinze.dev and @mazenchami.dev talk Claude, Cursor, Expo Agent and what building React Native apps actually looks like in the AI era. Listen now 👇 infinite.red/react-native...

Yatsi can compile and evaluate functional closures now, and you can watch in the closure visualizer: yatsi.dev/closures/ It's still tailored to my own perspective on what's interesting. Gonna build a lot of these playgrounds until I figure out what's more useful for other people

In search of: updog joke, but it's about upvalues

Yatsi can finally return values from functions. And recursion just sort of works out of the box (I do have to add some call stack limits just in case): No real closures yet. Once I add that, I'll start working on some fun visualizations for how that all works under the hood.

Yatsi can run parameter-less functions that return `undefined` now:

Happening Wednesday 🚨 The one and only @wcandillon.bsky.social is joining React Native Live 🔥 He's talking to @mazenchami.dev about React Native Skia: high-performance UI, rich graphics, smooth animations. 📅 Wed, May 13 • 9 AM PT 🎥 youtube.com/live/GChgKhf...

Having a blast with more compiler visualizations. This one is helping me understand backpatching:

React Native is extremely capable. If you like deep dives about cross platform mobile apps in the real world, I would highly recommend this article.

🎤 Announcing: Seth Webster From leading React at Meta → co-founding the React Foundation → and now at @expo.dev… Seth has deeply shaped the ecosystem we all build in every day 🔥 Catch him live at Chain React 2026. 🎟️ ti.to/chainreact/c...

Playin' around with compiler visualizations. Here's some lexing from my toy TypeScript interpreter:

Thank you to @tannerlinsley.com for joining React Native Radio this week! Really excited to get this one out there.

Chain React Conf is one of my favorite conferences to learn about fresh ideas. If you’ve been working on React Native, this is a great place to share with the community. Speaking spots are still open so submit your talk by Friday! sessionize.com/chain-react-...

Todd hosting always makes for the best episodes. I have a feeling you’ll want to listen to this one.

Happy “tell lies on the internet” day to all who celebrate

🖤❤️ RNR 358 ❤️🖤 Build apps for Meta Quest using tools you already know? In Part 2, Evan Albert joins @mazenchami.dev and @robinheinze.dev to show how React Native devs can start shipping for the Quest headset 🥽 Listen now 👇 infinite.red/react-native...

i'm continually mystified why otherwise smart people keep publishing llm-assisted essays. the bla IS the bla; it's not foo, it's bar. look this shit just sucks to read, pls stop this

Really enjoyed the most recent issue of the React Native Newsletter. Short, sweet, and made me chuckle. If you aren’t reading, you’re missing out: mailchi.mp/infinite/rea...

It's been a while since MobX-State-Tree had a proper release (we have mostly slowed down development on it). But the last couple weeks have seen an influx of high quality PRs. In particular, applySnapshot is up to two orders of magnitude faster on 7.1.0, with no API changes. Strictly perf gains.

I don’t think it’s accurate to say something got “quietly” shipped if a bunch of people are talking about it on LinkedIn lol

Our team knows how to use AI. More importantly, we know when it's important to step in. Compliance, security, performance… the last 20% is where a seasoned engineer becomes critical. Our own @joshuayoes.com recently wrote about this and it's worth the read 👇 shift.infinite.red/you-built-an...

Hey this one rhymes!

I've known about the maxWorkers trick for a while, but a few months ago I sat down to dig into *why* it fixes things. This was a fun experimental set up. and if you are sick of blogs about AI, this one has none of that, so you may find it refreshing lol

🚀 AI is about to change React Native forever. We’re going live with This Dot Labs in 30 minutes to talk about it! Join @gantlaborde.com, Tracy Lee, @mazenchami.dev, @brandonmathis.bsky.social to see what's possible 👇 luma.com/m5etppc8?tk=...

🖤❤️ RNR 356 ❤️🖤 Building Vercel’s v0 mobile app with Fernando Rojo! ​ @mazenchami.dev and @robinheinze.dev talk with Fernando about React Native, @expo.dev, native-level performance, sharing code with web, and more. Link in thread 🧵

Ok so I tried the Big Arch and I think I understand why that CEO video went so poorly. It’s too wide, doesn’t stay together easily. It’s an awkward sandwich to eat, and they made an awkward person eat it. Tastes fine but won’t replace my normal McDonalds order anytime soon

Thinking I’m gonna mess around with Skia this weekend…

Tickets are going fast 🎟️ Get your Chain React ticket at the best price before we announce our epic speaker lineup. Prices go up after. Lock yours in today 👇 ti.to/chainreact/c...

🤖AI is changing A LOT about React Native development. Chain React is your guide through it! We'll have lots of AI topics at the conf. Blind Bird tickets are the BEST price and the price goes up when speakers are announced. Grab yours today 🎟️ ti.to/chainreact/c...

Isn’t it wild that a few years ago people were still sort of debating over TypeScript adoption, and now we’re like “hmm should I give my autonomous coding robot full permissions to my machine, or make it do PRs in the cloud that I have another robot read?”

if you believe in any form of free enterprise at all, the idea that the Pentagon can not only cut off your contract but designate you a supply chain risk and prevent other companies from buying from you just because you won't build killbots for the government should be terrifying

So who is gonna be the one to tell Pete Hegseth how many massive American companies are investors in Anthropic?

🖤❤️ RNR 354 🖤❤️ Krzysztof Magiera (@kzzzf.bsky.social) joins @mazenchami.dev and @robinheinze.dev to talk React Native Screens! This discussion goes deep into how it started + where it's headed with a V5 rewrite built for the New Architecture. Listen now! 👇 infinite.red/react-native...

You can take the boy out of the Naugatuck River Valley, but he will return to the Naugatuck River Valley

The idea that coding agents prove "learn to code was a mistake" is kind of analogous to thinking the printing press meant "psych! y'all wasted a lot of time learning how to write." Computational thinking is getting easier to pick up, and also providing more leverage than before.

We’re gonna want new modalities of configuring and paying for services. I’m tired of making tokens and giving them to Claude. So I made a static web host that treats LLMs as the primary interface. LLM requests a token, you pay with a Stripe link, LLM can use token to do stuff. shipsite.sh

RNR is taking a break this week 😮‍💨 But if you missed RNR 346, now's your chance! It's one of our most popular episodes. Mustafa and Thiago from Shopify talk migrating to the new architecture: what worked, what broke, and more! infinite.red/react-native...

History, rhyming, etc…. en.wikipedia.org/wiki/Softwar...

I've been running Claude with `--dangerously-skip-permissions` on an old Macbook I wiped and it's so nice. When I *do* run Claude on my real machine I find it so jarring how much it needs from me (rightfully so) to run commands.

Really wanna buy the software dip… lots of analysts who don’t understand the limitation of AI. There’s alpha to be had lol.
