AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance on using the create-react-native-library CLI to scaffold new React Native libraries or integrate local native modules and views into existing applications. It covers the setup process for various library types, including Turbo Modules, Nitro Modules, and Fabric components, ensuring proper configuration for both standalone projects and monorepo-style local development.

What it does

  • Scaffolds new standalone React Native libraries for npm distribution
  • Integrates local native modules or views directly into existing React Native apps
  • Configures project structures for Turbo Modules, Nitro Modules, and Fabric components
  • Sets up example applications using Expo or React Native Community CLI
  • Provides standardized project layouts with native implementation folders
  • Guides users through post-scaffolding dependency installation and build tasks

When to use it

  • When starting a new React Native library project
  • When adding custom native functionality to an existing React Native application
  • When wrapping native SDKs for use within a React Native environment
  • When you need to create native UI components or native APIs

Advantages

  • Ensures consistent project structure across different library types
  • Automates complex setup for native modules and autolinking
  • Provides built-in example apps for immediate testing and development
  • Supports modern React Native architectures like Turbo Modules and Nitro

Usage examples

“Scaffold a new React Native library named my-native-lib with Turbo Modules and an Expo example.”
The agent executes the CLI command with the appropriate flags to generate a library structure with Kotlin/Obj-C support and an Expo example app.
“How do I add a local native module to my existing React Native project?”
The agent provides the command to run the CLI with the --local flag from the app root, creating a module under the modules/ directory.

Documentation by Callstack

Create React Native Library

Overview

Use this skill to scaffold a standalone React Native library or a local library inside an existing app, then continue with the correct implementation docs.

Examples:

  • JS-only library that may use other React Native libraries

  • Native modules that expose native functionality to JavaScript

  • Native UI components that render native views in React Native

When to Apply

Use this skill when:

  • Creating or working on a React Native library with create-react-native-library

  • Creating a native module or view in an existing app

  • Wrapping native SDKs and exposing them to React Native

Quick Reference

# Inspect current options before scaffolding
npx create-react-native-library@latest --help

# Scaffold a library with turbo modules and the Expo example app
npx create-react-native-library@latest awesome-library \
  --no-interactive \
  --yes \
  --description "A brief description of the library" \
  --type turbo-module \
  --languages kotlin-objc \
  --example expo

# Scaffold a local Turbo Module inside an existing app
cd MyApp
npx create-react-native-library@latest awesome-library \
  --local \
  --no-interactive \
  --yes \
  --description "A brief description of the library" \
  --type turbo-module \
  --languages kotlin-objc
