Developing Expo Modules

This skill helps you create and develop expo-modules for React Native app to call native iOS code.

When to use this skill

Use this skill when you need to:

• Create or modify Expo modules for React Native applications.
• Interface with native iOS code using the Expo Modules API.

Creating a new Expo module

This only needs to be done once per module.

1. Run bunx create-expo-module@latest --local to scaffold a new local Expo module.
2. Follow the prompts to set up your module.

Developing

1. Navigate to your module directory, likely ./modules/<your-module-name>.
2. Make code changes to the .ts and .swift files as needed.

Building and testing

Each time you make changes to the native code, you need to rebuild the native bundle and run the app.

bunx expo run:ios \
  --device "Kevin's iPhone" \
  --scheme tindeqtrackerdev
