For the record the case for usage is pretty common - you need site with SSR plus pretty big dashboard as `/admin` route as SPA for faster speed/more convenient data fetching/shared state across routes...

Thanks @leerob.com ! From docs i found out that:
- SPA mode in config is all or nothing
- `dynamic` can restrict to CSR only component, not route

Conclusion is Next.js router doesn't allow CSR for single route(and sub-routes), to do it i need to add 3rd party router.

Or am i missed something?

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

3. Reactivity of nested data change DOES NOT WORK when data changed on one screen and observed on another one

I'll try to dedicate more time for investigation, but if you have any thoughts why observer could work with primitives and not work with objects in different mobile screens, pls let me know

Was not able to track down root cause, but that's where i stopped by:

1. Reactivity of nested data change(as in initial post) WORKS on the same `expo-router` screen[mobile native]
2. Reactivity of primitives change WORKS on when data changed on one screen and observed on another one

Thanks for quick response Jay. Yeah, tests seems to cover my case. I'll try to isolate the code and update you with my findings...

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?

🥓 Expo Router v5 is packed with powerful new features to help you build beautiful full-stack native apps.

◆ Improved Errors and Logging
◆ API Routes in Production
◆ React Server Functions (Beta)
◆ ....and way more!

All the deets are in the blog from @bacon.bsky.social:

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. 🧵👇

Amazing job! 😍

Did you compare perf with the new FlashList 2 alpha?

Legend List 1.0 is LIVE!

The ⚡️ fastest React Native list library, 100% JS, with powerful new features. For new and old arch.

✨ maintainContentVisiblePosition
✨ Bidirectional infinite scrolling
✨ Chat UI without the inverting hack

I hope it helps make your apps better!

Expo SDK 53 beta is now available - Expo Changelog Learn about the changes, how to try it out, and how to give feedback.

🆕 We just released the SDK 53 beta. Please go test it out and make sure it doesn't introduce any regressions for you.

Just a heads up that we’ll be releasing fixes and improvements during the ~2 week beta period — some of these may include breaking changes.

Legend List is getting very close to 1.0! Please try it and try to find bugs 🐞

I'm trying to make sure it's extremely stable and covers all of your edge cases before 1.0 ❤️

Hola, thank You! Just curious, do you use RN's TextInput in a new solution or building from the ground up?

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

It's all great, but when we'll be able to use Expo insights? At least the ability to turn it on/off by code?

Insane performance guys! 60fps all the way

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.

I finally recreated the Airbnb slider in React Native ✨
I've been wanting to do this since it came out.

🔥 Tried out a shiny metal card effect!

Built with @expo.dev, @swmansion.com's Reanimated, and @wcandillon.bsky.social's RN Skia.

Big shoutout to @jerinjohnk.bsky.social, followed his implementation, and his blog made it super easy to understand.

Here’s my take on it, check out the video! 👇

amazing, thnx!

hey man
any chance you can drop the gist of the custom button based on `PureNativeButton`? it shouldn't be clean/polished, just to save the time not diving into `useHandler`/`useEvent` w/o docs...🫠

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?
