expo-migrate-module

An agent skill by expo, from expo/skills. Tags: mobile, react-native, web.

What it does

Framework (OSS). Migrate an existing Apple/Swift Expo native module from the Expo Modules API 1.0 definition DSL to the 2.0 macro API (sometimes called v2) while preserving its JavaScript and TypeScript contract. Use when converting or incrementally adopting @ExpoModule, @JS, @Event, @SharedObject, or @Record in an existing module. Do not use for creating a new module, general Expo SDK upgrades, or Android/Kotlin migrations.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add expo/skills --skill expo-migrate-module

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/expo/skills
cp -r skills/plugins/expo-experiments/skills/expo-migrate-module ~/.claude/skills/expo-migrate-module
