React Native vs Next.js: Architecture strategies for maximum code reuse
Sharing business logic, API clients, and state management across mobile apps and web platforms while keeping UI components native where performance demands it.
Avoiding the write-once-run-everywhere trap
Attempting to force identical UI component code across web and native mobile platforms leads to compromised UX on both. Web interfaces demand mouse hover states and fluid CSS grids, while iOS and Android require native gesture handlers and safe-area layouts.
The shared business logic monorepo model
Structure your application as a monorepo (using Turborepo or Nx). Move shared API SDKs, TanStack Query hooks, state stores (Zustand/Redux), and validation logic into a core `@workspace/core` package.
Both your Next.js web app and React Native mobile app import the exact same authentication, data fetching, and business validation functions while maintaining platform-native rendering layers.
