uniffi-bindgen for React Native

uniffi-rs is a suite of projects to allow Rust to be used from other languages. It was started at Mozilla to facilitate building cross-platform components in Rust which could be run on Android and iOS.

It has since grown to support for other languages not in use at Mozilla.

uniffi-bindgen-react-native is the project that houses the bindings generators for React Native, the Web, and Node.js.

It supports all language features that uniffi-rs supports, including:

• calling functions from Typescript to Rust, synchronous and asynchronous.
• calling functions from Rust to Typescript, synchronous and asynchronous.
• objects with methods, including:
  • garbage collection integration.
  • uniffi traits
• custom types

It contains tooling to generate bindings:

• for Hermes via JSI, and to generate the code to create turbo-modules.
• for WASM, using wasm-bindgen, and the WASM crate.
• for Node.js, calling a compiled cdylib through an N-API runtime.

New projects depend on the @ubjs runtime packages; see Packages for what to install. Code generated before those packages existed keeps working unchanged.
