What problem does it solve? Building a React Native native module with the Nitro framework involves many error-prone steps: scaffolding a monorepo, writing HybridObject TypeScript specs, running Nitrogen codegen, implementing generated specs in Swift, Kotlin, or C++, wiring an example app, and preparing the package for npm publishing. This Skill guides the entire workflow with Nitro-specific API design rules and platform implementation patterns. ## Core Features & Use Cases - End-to-end module scaffolding: Initialize a Nitro library with Nitrogen, configure nitro.json autolinking, and set up a monorepo with an example app for real-device testing. - HybridObject API design: Apply Nitro-specific rules for factories, native state ownership, zero-copy data, listener subscriptions, Promise-based async boundaries, and Hybrid View components. - Native implementation guidance: Implement generated specs correctly in Swift, Kotlin, or C++ with proper threading, Promise helpers, annotations, and file organization. - Use Case: You want to create a react-native-math library with a native Math HybridObject. The Skill walks you through nitrogen init, writing Math.nitro.ts, running codegen, implementing HybridMath in Swift and Kotlin, and running the example app on Android and iOS. ## Quick Start Ask the assistant to create a new Nitro Module library, then answer its questions about the library name, monorepo layout, example app, native languages, and module purpose.
