Write ultra fast React Native modules in Rust

jsi-rs

This library makes it possible to write React Native JSI modules in Rust.

For an example, check out the example folder.

Getting Started

1. Clone this repo
2. Run git submodule init
3. Run git submodule update, this will ensure that all the vendor dependencies are cloned locally
4. Make sure you have Ninja installed locally, which is necessary for building Hermes. You can find instructions here. On macOS, you can install it with brew install ninja
5. Install dependencies for the example app: cd example && yarn install
6. Run the example app on android with yarn android

NOTE: Make sure that you have not installed rust with homebrew on mac, use the rustup toolchain instead.

Contributing

I wrote this code in winter 2022 as part of another project. A few months later, I have decided to release it to the world. However, I'm not planning to maintain it unless I encounter another project that requires it, so for now, the code is given to you as-is. Feel free to contribute PRs that would improve the API or stability of the library.

Safety

Right now, this library is quite unsafe.
