Expo Router Navigation

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

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">  <Link.Trigger>    <Pressable>      <Card />    </Pressable>  </Link.Trigger>  <Link.Preview /></Link>

Link preview can be used with context menus.

Modal

Present a screen as a modal:

tsx
<Stack.Screen name="modal" options={{ presentation: "modal" }} />

Prefer this to building a custom modal component.

Sheet

Present a screen as a dynamic form sheet:

tsx
<Stack.Screen  name="sheet"  options={{    presentation: "formSheet",    sheetGrabberVisible: true,    sheetAllowedDetents: [0.5, 1.0],    contentStyle: { backgroundColor: "transparent" },  }}/>
  • Using contentStyle: { backgroundColor: "transparent" } makes the background liquid glass on iOS 26+.

Common route structure

A standard app layout with tabs and stacks inside each tab:

app/  _layout.tsx — <NativeTabs />  (index,search)/    _layout.tsx — <Stack />    index.tsx — Main list    search.tsx — Search view
tsx
// app/_layout.tsximport { NativeTabs } from "expo-router/unstable-native-tabs";import { ThemeProvider, DarkTheme, DefaultTheme } from "expo-router/react-navigation";import { useColorScheme } from "react-native";
export default function Layout() {  const colorScheme = useColorScheme();  return (    <ThemeProvider value={colorScheme === "dark" ? DarkTheme : DefaultTheme}>      <NativeTabs>        <NativeTabs.Trigger name="(index)">          <NativeTabs.Trigger.Icon sf="list.dash" md="list" />          <NativeTabs.Trigger.Label>Items</NativeTabs.Trigger.Label>        </NativeTabs.Trigger>        <NativeTabs.Trigger name="(search)" role="search" />      </NativeTabs>    </ThemeProvider>  );}

Create a shared group route so both tabs can push common screens:

tsx
// app/(index,search)/_layout.tsximport { Stack } from "expo-router/stack";import { colors } from "@/theme/colors";
export default function Layout({ segment }) {  const screen = segment.match(/\((.*)\)/)?.[1]!;  const titles: Record<string, string> = { index: "Items", search: "Search" };
  return (    <Stack      screenOptions={{        headerTransparent: true,        headerShadowVisible: false,        headerLargeTitleShadowVisible: false,        headerLargeStyle: { backgroundColor: "transparent" },        headerTitleStyle: { color: colors.label },        headerLargeTitleEnabled: true,        headerBlurEffect: "none",        headerBackButtonDisplayMode: "minimal",      }}    >      <Stack.Screen name={screen} options={{ title: titles[screen] }} />      <Stack.Screen name="i/[id]" options={{ headerLargeTitleEnabled: false }} />    </Stack>  );}

headerLargeTitleEnabled is the SDK 56+ option name; older SDKs use headerLargeTitle, which is deprecated upstream.

Submitting Feedback

If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve:

bash
npx --yes @expo/agent-cli@latest feedback --category skills --subject "expo-router" "<actionable feedback>"

Only submit when you have something specific and actionable to report. Include as much relevant context as possible. If an agent repeatedly fails at an Expo task or the user has to step in, submit a brief report of the task, expected result, and what went wrong using --category evals and the relevant Expo package or command as --subject.
