Just released react-native-columnar 🚀

A zero-copy columnar transport for React Native built around ArrayBuffer + TypedArrays.

Benchmarks are pretty wild:

• 27× faster at 100 rows
• 94× faster at 500 rows
• 121× faster at 1000 rows
• 208× faster at 2000 rows

Really cool stuff 🔥

We just released react-native-runtimes! 🥳
👉 Render React components on separate JS Runtimes
👉 Share state (Zustand) across Runtimes, synced in C++
👉 Dual-Thread-approach for rendering/business logic
We plugged this into MetaMask which made the app start substantially faster:

@ospfranco That's understood - maybe I misunderstood your tweet. What I meant is that moving from a pure HostFunction to calling the same function through NativeState adds almost no overhead
HostObject case is a different story
HostObject: 188ms
NativeState: 38ms
HostFunction: 26ms

@peterpme It won’t be the last one, will be part 2, then 3 , 😃

[Alex @pioner_dev]

@BoazWith I will add it 👍

[Alex @pioner_dev]

@BoazWith Do you think this is necessary ? since the user of the library will never touch this and works under the hood

[Alex @pioner_dev]

@peterpme if you return some data from the native side, and the data is like Array<{id: number, isActive: bool}>, and there are a lot of objects, you should try this solution, it's much faster

[Alex @pioner_dev]

@BoazWith When the last reference is destroyed, the class destructor is called and releases all resources

[Alex @pioner_dev]

@BoazWith it will be destroyed when both sides no longer hold it

@mrousavy @SamuelScheit the best solution (nitrogen schema generation )

[Alex @pioner_dev]

@mau_dev_uday Yeah, preparing a package 😃

[Alex @pioner_dev]

@gabimoncha react-native-quick-base64: Yes, it has the same API.
this -> react-native-quick-crypto I am not sure

[Alex @pioner_dev]

Just published a new release of react-native-turbo-base64 with more optimizations 🚀

[Alex @pioner_dev]

@SamuelScheit @mrousavy yep 😀
