Build cross-platform mobile apps with Expo SDK and React Native. Expo provides a managed workflow with built-in APIs (camera, location, SQLite, notifications, auth). Expo Router provides file-based navigation. EAS Build handles native compilation. OTA updates skip app store review. Cross-platform iOS + Android apps from one codebase Apps needing native features (camera, GPS, biometrics) MVPs requiring fast iteration with OTA updates Teams wanting to avoid native build tooling setup 1. Scaffold: npx create-expo-app my-app --template blank-typescript, then cd my-app && npx expo start. 2. Add routing: install expo-router and use file-based routes under app/ (or run with the default router template). 3. Configure native APIs: run npx expo install expo-camera expo-location expo-sqlite and add the plugin config in app.json. 4. Develop on device: open in Expo Go or run npx expo run:ios/run:android for a native dev build. 5. Store data locally: use expo-sqlite (SQL via db.getAllAsync) or AsyncStorage for key-value state. 6. Ship: eas build --platform all, then eas submit; iterate with npx expo update (OTA). Use Expo SDK with Expo Go for fast development iteration. Manage dependencies with
