Quick, modder-friendly recipes for common React Native patterns. Copy, paste, tweak.
Tip: keep examples in a /sandbox app and promote stable pieces into core/.
See also: ../sandboxes/react-native-expo for a minimal Expo starter. Wrap your root with NavigationContainer and/or QueryClientProvider as noted in each guide.
Expo (recommended on Windows)
# 1) Create a sandbox app
npx create-expo-app@latest rn-sandbox
cd rn-sandbox
# 2) Install libs as needed per pattern (pick what you use)
npx expo install @tanstack/react-query
npx expo install @react-navigation/native @react-navigation/native-stack react-native-screens react-native-safe-area-context
npx expo install @react-native-async-storage/async-storage
npx expo install react-native-mmkv
npx expo install expo-router # only for the Expo Router guide
# 3) Run
npx expo start
Then copy files from a pattern page into your app/ or src/ folders (e.g., screens/, hooks/, navigation/) and tweak imports. For React Navigation, wrap your root with NavigationContainer. For React Query, wrap with a QueryClientProvider.
