brownfield-navigation

# Overview Brownfield navigation has three steps: 1. Define `brownfield.navigation.ts` 2. Run `npx brownfield navigation:codegen` 3. Wire native delegates before JS calls Read only the smallest reference that matches the question. ## Routing (concern -> file) Concern | Read --------|------ Contract file location, supported signatures, codegen command, generated artifacts | [`references/setup-codegen.md`](references/setup-codegen.md) Calling methods from React Native, `undefined is not a function`, API drift after contract edits | [`references/javascript-usage.md`](references/javascript-usage.md) iOS-only delegate implementation and startup registration | [`references/native-ios-integration.md`](references/native-ios-integration.md) Android-only delegate implementation and startup registration | [`references/native-android-integration.md`](references/native-android-integration.md) ## Minimal command reference ```bash npx brownfield navigation:codegen npx brownfield package:ios npx brownfield package:android npx brownfield publish:android ```
