open-native VS hermes

What they decided to do is really quite strange. Something like Capacitor makes much more sense but they said they wanted access to React Native libraries... I hope https://github.com/OpenNative/open-native can address their requirements in the future. It's goal is to make things like React Native native modules work across frameworks (e.g., react native libraries working in capacitor and native script)

You can now use React Native plugins within NativeScript projects through the Open Native effort and it's only a matter of time before NativeScript can be used where the React Native community sees fit.

As NativeScript offers a cross-platform UI abstraction, you can build your whole UI without writing platform-specific code. There are often cross-platform plugins available to avoid having to write any platform-specific code, and in fact we’ve recently built Open Native to allow you to use React Native native modules in NativeScript apps (Svelte Native included). But even when there is no plugin available, writing the native code is a breeze, as it has full TypeScript typings and you can pass real native values back and forth between native and JS rather than just JSON-serialisable ones. It’s really quite incredible!

Open Native is the long overdue Rosetta Stone that allows native modules to be used cross-ecosystem. It handles all the necessary auto-linking, type marshalling and API-binding to allow you to choose the highest quality native module for your project, no matter what ecosystem it comes from.

The complete steps to run the benchmarks are available in the main repo: https://github.com/OpenNative/open-native/blob/main/benchmark.md

Hermes is a big one as well: low startup latency, low memory

Hermes

InstagramBundle.js.hbc.spk.xz is likely a compressed version of Hermes bytecode (js.hbc)"

In React Native's case, it uses an engine called Hermes:

📜 I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.

For me it’s a JS engine for React Natve - https://hermesengine.dev/

💉 Building and injecting a JS bundle a basic concept: If the native code wasn’t changed, simply create JS bundle and inject it into the precompiled application. (You must take an extra step to convert a js file to bytecode if you use the Hermes js engine.)
