What it is

React Native is a cross-platform mobile framework that lets developers write native Android and iOS apps using React and JavaScript. It renders to native UI components (not WebView), providing genuine native performance and platform-specific behavior while sharing a single codebase across platforms. Monorepo structure: packages/react-native/src/ contains the public API and cross-platform logic; packages/react-native/src/private/ segregates internal components (animated/, assets/, components/, devsupport/), each with multiple platform implementations. Native Android code lives in C++/Kotlin/Java under ReactAndroid/; iOS/Objective-C in parallel. Development tools (eslint, prettier, flow,…

Start here

Open these first:

• packages/react-native/src/asset-registry.js — Entry point for asset registration system used across React Native components and modules.
• packages/react-native/src/private/featureflags/ReactNativeFeatureFlags.js — Central feature flag management controlling experimental and production behavior across the framework.
• packages/react-native/src/private/renderer/events/dispatchNativeEvent.js — Core event dispatcher bridging native platform events to React event handlers.
• packages/react-native/src/private/animated/NativeAnimatedHelper.js — Helper for native animation bridge communication, critical for performance-sensitive UI animations.
• packages/react-native/src/private/devsupport/devmenu/DevMenu.js — Developer menu orchestrator providing debugging, inspection, and hot-reload capabilities.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/facebook/react-native.git
cd react-native
yarn install
yarn start          # Start rn-tester development server
# For Android: yarn android
# For iOS: yarn test-ios

The monorepo uses yarn 1.22.22 (see packageManager field); follow repo documentation for platform-specific setup (Android SDK/NDK, Xcode).

Daily commands:

yarn start              # Start development server for rn-tester app
yarn android            # Build and run Android (via packages/rn-tester)
yarn test-ios           # Run iOS tests (./scripts/objc-test.sh test)
yarn test-ci            # Run Jest suite with jest-junit reporters

Each command maps to cwd-scoped yarn runs or gradle/shell orchestration defined in root package.json scripts.

Key cautions & unknowns

• Monorepo complexity: Changing one file may require rebuilds across multiple platforms (Android via Gradle, iOS via Xcode). Native bridge fragility: Errors in native module mappings cause runtime crashes, not…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
