@TomaszLorencDev GitKraken? Huh, are they still around?

[Dorian Mazur @dorian__mazur]

We’re hiring React Native engineers at Kraken 🐙
If you care about performance and the little details that make an app feel great, DM me.

[Dorian Mazur @dorian__mazur]

@josefrichter React Native is native, and it’s only slow if you don’t know how to use it.

[Dorian Mazur @dorian__mazur]

@mustafaabobakr_ No idea who you're talking about 😁

[Dorian Mazur @dorian__mazur]

@KennethBrattli Interesting, I will check it out

[Dorian Mazur @dorian__mazur]

Dynamic trays are coming to react-native-screen-choreography.
Built-in navigation, animated transitions, and views that keep their state when you go back. All inside a sheet that resizes to fit, or expands to full screen.
Try it in 0.8.0-alpha.0

[Dorian Mazur @dorian__mazur]

@krsnphnx How so?

[Dorian Mazur @dorian__mazur]

Krak just got some seriously smooth screen transitions 😍
Built with react-native-screen-choreography and react-native-teleport.
More coming to the Kraken apps 👀

[Dorian Mazur @dorian__mazur]

@wgmi420 @zuhayr_dev @egorvodopyanov It’s only for testing the internals right now, but it’ll be possible to use in the future. I just patched it so I could use it for the library. No weirdness at all, it works great.

[Dorian Mazur @dorian__mazur]

React Native can feel like this 😍
Been squeezing more performance out of react-native-screen-choreography.
Performance tests run on every commit to help keep it smooth.

[Dorian Mazur @dorian__mazur]

@reactiive_ How about Skia, WebGPU and Codex? 🤔

[Dorian Mazur @dorian__mazur]

For anyone curious about the implementation, the library, example apps, and performance tests are all in the repo (including React Native Fantom benchmarks) 👇

@zuhayr_dev @egorvodopyanov They flag slowdowns for review rather than failing CI on timing alone. Each scenario runs 20 round trips, and I compare medians against a compatible baseline. There’s some variation between GitHub runners, but the results are still useful for spotting regressions.

[Dorian Mazur @dorian__mazur]

@erikkovari @egorvodopyanov GitHub Actions is free for public repositories. Slow? 20–30 minutes isn’t quick, but I’m in no rush.

[Dorian Mazur @dorian__mazur]

@egorvodopyanov The tests replay navigation journeys and measure layout preparation, transition presentation timing, and render counts. Each scenario runs 20 round trips on iOS/Android, with results compared against a baseline.

[Dorian Mazur @dorian__mazur]

@ChmalSzymon Nice! How does it compare to Astra?

[Dorian Mazur @dorian__mazur]

People ask me about Android (it’s not even a release build)

[Dorian Mazur @dorian__mazur]

Here’s a taste of what you can build with react-native-screen-choreography, and there’s plenty more to explore.
0.6.0 is coming soon with better performance and new helpers for smoother transitions 👀
Oh, and it has docs now: https://t.co/5cD2BbuvUl
