// Overview

How we use React Native

React Native enables us to build iOS and Android apps from a single TypeScript codebase. With Expo and the new architecture, React Native apps deliver near-native performance with meaningfully faster development cycles than separate native codebases.

// Use cases

  • Cross-platform iOS and Android apps
  • Apps sharing logic with Next.js web apps
  • Consumer apps prioritising development speed
  • Internal tools for iOS and Android

// Why it matters

Shared codebase

70–90% of code shared between iOS and Android. TypeScript types and business logic shared with web applications in a monorepo.

Expo ecosystem

Expo provides native modules, OTA updates, and managed build infrastructure, reducing native toolchain complexity significantly.

New Architecture

JSI and Fabric renderer in React Native 0.73+ provide synchronous JS-native communication and concurrent rendering, resolving historic performance concerns.

// Production patterns

How we ship with React Native

Expo prebuild with EAS for store releases; OTA updates for JS-only fixes when Apple review cycles would block critical copy changes.

Offline-first patterns use WatermelonDB or SQLite queues with background sync and idempotent API IDs, field inspection and logistics apps are common shapes.

Crashlytics + Sentry with release health; staged rollouts via Play internal tracks before production percentage ramps.

// FAQ

React Native: common questions

React Native vs native Swift/Kotlin?+

React Native when time-to-market and shared logic with web matter. Native when AR, heavy GPU, or platform APIs dominate the product.

Do you publish to both stores?+

Yes, App Store and Play Console assets, privacy nutrition labels, and review response support included in launch scope.

How do you handle push notifications?+

FCM + APNs via Expo Notifications or OneSignal; deep links tested on cold start and background kill states.
