Nitro is a framework for building fast, type-safe native modules for React Native (and any JSI environment) implemented in C++, Swift, or Kotlin. It includes a core library (react-native-nitro-modules) and an optional code generator (nitrogen) that statically compiles type-safe bindings from TypeScript interfaces.

Use cases

• write react native native modules in swift instead of objective-c
• create fast c++ native modules for react native
• generate type-safe jsi bindings from typescript interfaces
• call native kotlin code from javascript in react native
• speed up native method calls compared to turbomodules
• build cross-platform native modules with c++ for ios and android

When to choose

• you need high-performance native-to-JS communication in React Native with minimal overhead
• you want to write native modules in Swift or Kotlin without Objective-C or JNI boilerplate
• you want compile-time type safety between TypeScript and native code

When to avoid

• you only need simple native modules and prefer the mainstream Expo Modules or Turbo Modules ecosystem
• your project does not use React Native or any JSI-based JavaScript runtime
• you need a mature ecosystem with extensive third-party module support
