expo-module: a Claude Code skill by Expo
Official
For Expo developers who need native Swift or Kotlin code exposed to their React Native app. Skip it if ready-made Expo packages cover your needs or you're moving to the 2.0 macros.
Before you install: It asks Claude to report errors and failed tasks to Expo by running `npx --yes @expo/agent-cli@latest feedback`, which fetches the newest CLI without a prompt.

What does expo-module do?
expo-module is a skill that guides Claude through writing Expo native modules and views in Swift, Kotlin and TypeScript. It tells Claude to scaffold with create-expo-module rather than making folders by hand, choosing local or standalone, the target platforms, and features such as Function, AsyncFunction, Event, View or SharedObject. Claude then swaps the generated samples for the real code. Reference files cover the module definition DSL, native view props and events, lifecycle hooks, config plugins that edit Info.plist or AndroidManifest.xml, and expo-module.config.json autolinking. Adding a platform later goes through add-platform-support. Moving a module to the 2.0 macros is left to a separate skill.
When should you use expo-module?
Use it when
- You need a camera, sensor or system API Expo doesn't wrap
- You want to wrap a native iOS or Android SDK for React Native
- You need a config plugin that edits Info.plist or AndroidManifest.xml
Skip it when
- Existing Expo packages already do what you need
- You are migrating a Swift module to the 2.0 macros
What it needs and what it can touch
You need
- An Expo project
What it can do
- Runs shell commands (create-expo-module)
- Reads and edits native and TypeScript project files
- Can send feedback to Expo through @expo/agent-cli
From reading its instructions, not from running it.
