# Expo Router Navigation

Navigation and routing for Expo Router apps. For screen styling, colors, controls, animations, media, and visual effects, use the `expo-native-ui` skill.

## References

Consult these resources as needed:

```
references/
  route-structure.md     Route conventions, dynamic routes, groups, folder organization
  tabs.md                NativeTabs, migration from JS tabs, iOS 26 features
  toolbar-and-headers.md Stack headers and toolbar buttons, menus, search (iOS only)
  form-sheet.md          Form sheets in expo-router: configuration, footers and background interaction.
  search.md              Search bar with headers, useSearch hook, filtering patterns
  zoom-transitions.md    Apple Zoom: fluid zoom transitions with Link.AppleZoom (iOS 18+)
```

## Code Style

- Always use kebab-case for file names, e.g. `comment-card.tsx`
- Always remove old route files when moving or restructuring navigation
- Never use special characters in file names
- Configure tsconfig.json with path aliases, and prefer aliases over relative imports for refactors.

## Routes

See `./references/route-structure.md` for detailed route conventions.

- Routes belong in the `app` directory.
- Never co-locate components, types, or utilities in the app directory. This is an anti-pattern.
- Ensure the app always has a route that matches "/", it may be inside a group route.

## Library Preferences

- `Color` from `expo-router` for native semantic colors, not raw `PlatformColor` (type-safe, auto-adapts to light/dark). See `expo-native-ui` for the full color palette pattern.
- In SDK 56+, never import from `@react-navigation/*` directly — use `expo-router/react-navigation` instead (covers `@react-navigation/native`, `/core`, `/elements`, `/routers`)

## Behavior

- Prefer `Stack.SearchBar` to add a search bar to a screen

# Navigation

## Link

Use `<Link href="/path" />` from 'expo-router' for navigation between routes.

```tsx
import { Link } from 'expo-router';

// Basic link
<Link href="/path" />

// Wrapping custom components
<Link href="/path" asChild>
  <Pressable>...</Pressable>
</Link>
```

Whenever possible, include a `<Link.Preview>` to follow iOS conventions. Add context menus and previews frequently to enhance navigation.

## Stack

- ALWAYS use `_layout.tsx` files to define stacks
- Use Stack from 'expo-router/stack' for native navigation stacks

### Page Title

Set the page title with `Stack.Title`:

```tsx
<Stack.Title>Home</Stack.Title>
```

## Context Menus

Add long press context menus to Link components:

```tsx
import { Link } from "expo-router";

<Link href="/settings" asChild>
  <Link.Trigger>
    <Pressable>
      <Card />
    </Pressable>
  </Link.Trigger>
  <Link.Menu>
    <Link.MenuAction
      title="Share"
      icon="square.and.arrow.up"
      onPress={handleSharePress}
    />
    <Link.MenuAction
      title="Block"
      icon="nosign"
      destructive
      onPress={handleBlockPress}
    />
    <Link.Menu title="More" icon="ellipsis">
      <Link.MenuAction title="Copy" icon="doc.on.doc" onPress={() => {}} />
      <Link.MenuAction
        title="Delete"
        icon="trash"
        destructive
        onPress={() => {}}
      />
    </Link.Menu>
  </Link.Menu>
</Link>;
```

## Link Previews

Use link previews frequently to enhance navigation:

```tsx
<Link href="/settings">
