**Nitro Modules** are highly efficient native modules with a statically compiled binding layer to JSI, and typesafe JS bindings.

It consists of two parts:

- [**react-native-nitro-modules**](packages/react-native-nitro-modules): The core C++ library powering all nitro modules

- [**nitrogen**](packages/nitrogen): A code-generator for nitro module library authors

## Installation

Install [react-native-nitro-modules](https://npmjs.org/react-native-nitro-modules) from npm:

```sh

npm i react-native-nitro-modules

cd ios && pod install

```

## Documentation

## Supported Platforms

### Cross-platform

Cross-platform native modules can be built with C++.

Any custom C++ types can be used and bridged to JS with minimal overhead.

JS <-> C++ type converters are statically generated ahead of time - no more dynamic lookups or runtime parser errors! 🥳

### iOS

iOS native modules and view components can be written either in pure C++, or pure Swift.

Thanks to Swift 5.9, Swift Nitro Modules [bridge directly to C++](https://www.swift.org/documentation/cxx-interop/) instead of going through Objective-C message sends. Woohoo, no more Objective-C, and **zero overhead** C++ -> Swift calls! 🥳

### Android

Android native modules and view components can be written either in pure C++, or pure Kotlin/Java.

Thanks to fbjni, even complex types can be effortlessly bridged to Kotlin/Java with minimal overhead! 🔥
