What it does

Implements an accepted incremental brownfield migration from native iOS or Android to React Native or Expo using @callstack/react-native-brownfield. Use after the brownfield path has been selected, when setting up the integration, packaging XCFramework or AAR artifacts, or adding React Native surfaces to native hosts.

Migrating to React Native

Use this skill only after the decision to adopt brownfield migration has been made. When the user is still choosing between brownfield, greenfield, a checkpoint-based path, defer, or no migration, use assess-react-native-migration first.

Overview

Prescriptive workflow for incremental adoption of React Native in existing native apps using @callstack/react-native-brownfield, from initial setup through phased host integration.

  • Expo track
  • Bare React Native track

Use one track per task unless the user explicitly asks for migration or comparison.

Migration Strategy

Use this strategy for brownfield migration planning and execution:

  1. Assess app state and select Expo or bare path.
  2. Perform initial setup with @callstack/react-native-brownfield.
  3. Package RN artifacts (XCFramework/AAR) from the RN source app.
  4. Integrate one RN surface into the host app and validate startup/runtime.
  5. Repeat integration by feature/screen for incremental rollout.
