Navigation Architect Skill

This skill ensures that the app's navigation is intuitive, performant, and follows Expo Router best practices.

Core Concepts

• File-based Routing: Map the file system to the app's navigation structure.
• Dynamic Routes: Use [id].tsx for dynamic segments.
• Layouts: Use _layout.tsx for shared UI (headers, tabs).
• Groups: Use (group) folders to organize routes without affecting the URL.
• Typed Routes: Leverage Expo Router's static typing for navigation.

Instructions

1. Map User Flow: Define how the user moves between screens.
2. Structure app/: Create the directory structure that matches the flow.
3. Handle Params: Use useLocalSearchParams for passing data.
4. Deep Linking: Ensure all routes are accessible via URI schemes.
5. Modals: Use layout groups and specific screen options for presentation.

Example

app/
  (tabs)/
    index.tsx       # Home tab
    settings.tsx    # Settings tab
    _layout.tsx     # Tab bar configuration
  details/
    [id].tsx        # Item detail screen
  _layout.tsx       # Root layout (Stack, ThemeProvider)
