How to force client-side rendering ONLY for whole route(page.tsx) in Next.js. Please don't tell me it's impossible...🫣

How to force client-side rendering ONLY for whole route(page.tsx) in Next.js. Please don't tell me it's impossible...🫣
On `legend-state` when `store$.prop.assign({ key: [1, 2] })` tracking it with `use$(store$.prop)` doesn't react. While working with primitives and arrays is super slick, it's absolutely unclear to me how to work with more complex objects+arrays data structures. Any hints?

I had a lot of moments reconsidering life choices or just raising alpacas instead of migrating, but it’s finally done. New architecture, @expo.dev SDK 53 (RN 0.79.1), and the fastest React Native app we’ve ever built (and I’ve ever seen!). Thanks to all contributors. Amazing achievement.

I was exploring a hard to debug memory leak in react native for at least 6 hours today. Turns out that when you don't add accessibilityLabel to RectButton or Pressable, it will fucking traverse all children to find a Text node or View with accessibilityLabel. This is insane. 1/4

Had some fun today deep-diving into Expo config plugins 🔌
Ran into an issue this week with an outdated plugin, so I used my day off today to fix it and learn more about how it all works. A few takeaways from the adventure below. 🧵👇

Seems like `react-native-live-markdown` seems as the only option for rich text editor. Is it possible to make format symbols(*,#,_) invisible?

I made an app that opens faster than any Mac app I've seen, loading a 5500 line markdown file instantly.
It's not Swift. Not Rust. Not C++.
It's JavaScript! react-native-macos is INSANELY fast 🤯
And 10% the size of an Electron app!
I had no idea RN on desktop is this good.
