Complete reference for creating Expo native modules and views with the Modules API, covering Swift (iOS), Kotlin (Android), and TypeScript. Reach for it when adding native functionality like camera or sensors to an Expo app, wrapping platform SDKs, or building config plugins. Handles module definition DSL, shared objects, lifecycle hooks, and autolinking—but not migrations from older DSL to 2.0 macros.
- Define native modules and views in Swift/Kotlin with TypeScript type bindings
- Wrap platform SDKs (camera, sensors, system APIs) for React Native consumption
- Create and edit config plugins that modify native project files and lifecycle hooks
- Set up autolinking, expo-module.config.json, and multi-platform module architecture
