React Native continues its reign as a premier choice for cross-platform mobile development, enabling Android and iOS applications from a single JavaScript codebase. For 2026, the ecosystem has matured significantly, simplifying development workflows. The recommended approach now centers on Expo, which has evolved into a comprehensive framework and ecosystem atop React Native—much like Next.js extends React for web development. Expo provides a robust SDK, a streamlined development environment, and integrated cloud deployment services (EAS), offering an opinionated yet highly beneficial path over raw React Native setups. Key recommendations for the modern stack include TypeScript for enhanced code quality, Expo Router for file-system-based navigation, and Expo Modules for pre-configured functionalities like maps, location, and icons. Productivity is further boosted by AI-powered code editors such as Cursor or VS Code with GitHub Copilot.

Building out the application, developers leverage sophisticated libraries for various concerns. For state management, Zustand or TanStack Query (the latter excelling in data fetching with caching and deduplication) are favored. Complex form handling is streamlined with React Hook Form paired with Zod for validation, or the modern TanStack Form. UI performance benefits from FlashList for large datasets, while React Native Reanimated and React Native Gesture Handler are indispensable for smooth animations and intuitive user interactions. Styling embraces utility-first approaches with NativeWind/Uniwind for Tailwind CSS integration, complemented by UI component libraries like React Native Reusables (akin to Shadcn UI) or Expo’s native-looking UI kit. Local data persistence is managed with Expo SQLite for relational data and MMKV for high-performance key-value storage. The deployment process is simplified through Expo Application Services (EAS) for cloud builds, and external services like Clerk (authentication), Sentry (analytics and error tracking), RevenueCat (in-app payments), and Backend-as-a-Service (BaaS) platforms such as Supabase or InstantDB complete the modern React Native application architecture.
