Expo Migrate Module

expo-migrate-module

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

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

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

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Expo Migrate Module

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /expo-migrate-module.

It contains no scripts, only instructions and reference files, so it can't run code on its own.
