React Native with Expo
Overview
Expo is an open-source framework for building universal native apps with React Native from a single TypeScript codebase. It provides file-based routing (Expo Router), cloud build services (EAS Build/Submit/Update), and a rich set of native modules for device APIs.
When to use: Mobile apps targeting iOS and Android, universal apps with web support, projects needing OTA updates, apps requiring native device APIs (camera, notifications, haptics), teams preferring managed infrastructure over bare React Native.
When NOT to use: Apps requiring heavy custom native code incompatible with Expo Modules API, brownfield integration into existing native apps, apps with native-only CI/CD requirements.
