GitHub Actions workflow patterns for React Native iOS simulator and Android emulator cloud builds with downloadable artifacts. Use when setting up CI build pipelines or downloading GitHub Actions artifacts via gh CLI and GitHub API.
GitHub patterns using gh CLI for pull requests, stacked PRs, code review, branching strategies, and repository automation. Use when working with GitHub PRs, merging strategies, or repository management tasks.
Provides an incremental adoption strategy to migrate native iOS or Android apps to React Native or Expo using @callstack/react-native-brownfield for initial setup. Use when planning migration steps, packaging XCFramework/AAR artifacts, and integrating them into host apps.
React Native core components, layout, styling, animations, lists, platform APIs, and best practices. Use when building iOS/Android UIs with native components.
React Native ecosystem — navigation, state, data fetching, Reanimated, storage, TypeScript patterns, accessibility, and deep linking. Use when building production React Native apps with React Navigation, Zustand, TanStack Query, or Reanimated v3.
Expo toolchain for React Native — Expo Router, EAS Build/Update/Deploy, native modules, SDK upgrading, and Expo UI/data patterns.

Deep performance reference. Canonical home for React Native performance — covers FlatList tuning, memoization, Hermes, expo-image, FPS measurement, bundle treemap analysis, Hermes mmap, R8 Android, 16 KB page-size alignment, view flattening, native threading, JNI memory patterns, and the profiling toolchain.
