Description
expo-module is an agent skill from the Expo skills collection that gives a coding agent a reference for writing Expo native modules and native views with the Expo Modules API, in Swift for iOS, Kotlin for Android and TypeScript for the JavaScript side. It covers the module definition DSL, including Function, AsyncFunction, Property, Constant and Events, as well as native views, shared objects and the type system, with examples in both Swift and Kotlin. The skill is meant for tasks such as creating a new native module or view, adding native features like camera, sensors or system APIs to an Expo app, wrapping a platform SDK for React Native, building config plugins that change native project files, and adding Android, Apple or web support to an existing module. It also covers editing expo-module.config.json and lifecycle hooks. For migrating a Swift module to the newer Expo Modules API 2.0 macros, the skill points to a separate expo-migrate-module skill. It is listed on skills.sh, where the page shows install counts, GitHub stars and security audit results.…
