Written by AutoGineer from the skill’s own files, not by the author
Expo Router provides a file-based routing system for Expo applications, enabling native navigation stacks, tabs, modals, and form sheets. It leverages a directory-based structure where the file system defines the app's route hierarchy. This skill covers route organization, dynamic routing, layout management, and native UI integration for headers, search bars, and context menus to ensure a consistent iOS and Android experience.
What it does
- Defines app navigation via file-based routing in the app directory.
- Configures native stacks, tabs, and modal presentations using _layout.tsx files.
- Implements dynamic routes and catch-all segments for flexible URL handling.
- Integrates native UI elements like search bars, headers, and context menus.
- Supports advanced presentation styles including form sheets with custom detents.
- Provides type-safe navigation and link previews for enhanced user interaction.
When to use it
- When building a new Expo application requiring native navigation.
- When migrating from standard React Navigation to a file-based routing architecture.
- When implementing complex navigation patterns like nested stacks, tabs, or modals.
- When you need to leverage native iOS/Android navigation features like form sheets or search bars.
Advantages
- Simplifies navigation logic by mapping the file system directly to app routes.
- Ensures native performance and look-and-feel across platforms.
- Promotes clean project structure by separating route definitions from business logic.
- Provides built-in support for native UI components like context menus and sheet detents.
Usage examples
- “How do I create a modal screen in my Expo Router app?”
- You define the modal in your _layout.tsx using Stack.Screen and set the presentation option to 'modal'.
- “How can I implement a form sheet that slides up from the bottom?”
- Configure a Stack.Screen with presentation: 'formSheet', define sheetAllowedDetents, and set the contentStyle background to transparent.
- “How do I add a context menu to a link in my app?”
- Wrap your component in a Link.Trigger and add a Link.Menu component containing Link.MenuAction items inside the Link.
- “What is the best way to organize routes for a tabbed application?”
- Use a root _layout.tsx with NativeTabs, then nest individual Stack navigators within group routes for each tab.

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.

Always use kebab-case for file names, e.g.
comment-card.tsxAlways 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
appdirectory.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
Colorfromexpo-routerfor native semantic colors, not rawPlatformColor(type-safe, auto-adapts to light/dark). Seeexpo-native-uifor the full color palette pattern.In SDK 56+, never import from
@react-navigation/*directly — useexpo-router/react-navigationinstead (covers@react-navigation/native,/core,/elements,/routers)
Behavior
Prefer
Stack.SearchBarto add a search bar to a screen
Navigation
Link
Use <Link href="/path" /> from 'expo-router' for navigation between routes.
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.tsxfiles to define stacksUse Stack from 'expo-router/stack' for native navigation stacks
Page Title
Set the page title with Stack.Title:
<Stack.Title>Home</Stack.Title>Context Menus
Add long press context menus to Link components:
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:
<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:
<Stack.Screen name="modal" options={{ presentation: "modal" }} />Prefer this to building a custom modal component.
Sheet
Present a screen as a dynamic form sheet:
<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// app/_layout.tsx
import { 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:
// app/(index,search)/_layout.tsx
import { 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:
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.

Route Structure
File Conventions
Routes belong in the
appdirectoryUse
[]for dynamic routes, e.g.[id].tsxRoutes can never be named
(foo).tsx- use(foo)/index.tsxinsteadUse
(group)routes to simplify the public URL structureNEVER co-locate components, types, or utilities in the app directory - these should be in separate directories like
components/,utils/, etc.The app directory should only contain route and
_layoutfiles; every file should export a default componentEnsure the app always has a route that matches "/" so the app is never blank
ALWAYS use
_layout.tsxfiles to define stacks
Dynamic Routes
Use square brackets for dynamic segments:
app/
users/
[id].tsx # Matches /users/123, /users/abc
[id]/
posts.tsx # Matches /users/123/postsCatch-All Routes
Use [...slug] for catch-all routes:
app/
docs/
[...slug].tsx # Matches /docs/a, /docs/a/b, /docs/a/b/cQuery Parameters
Access query parameters with the useLocalSearchParams hook:
import { useLocalSearchParams } from "expo-router";
function Page() {
const { id } = useLocalSearchParams<{ id: string }>();
}For dynamic routes, the parameter name matches the file name:
[id].tsx→useLocalSearchParams<{ id: string }>()[slug].tsx→useLocalSearchParams<{ slug: string }>()
Pathname
Access the current pathname with the usePathname hook:
import { usePathname } from "expo-router";
function Component() {
const pathname = usePathname(); // e.g. "/users/123"
}Group Routes
Use parentheses for groups that don't affect the URL:
app/
(auth)/
login.tsx # URL: /login
register.tsx # URL: /register
(main)/
index.tsx # URL: /
settings.tsx # URL: /settingsGroups are useful for:
Organizing related routes
Applying different layouts to route groups
Keeping URLs clean
Stacks and Tabs Structure
When an app has tabs, the header and title should be set in a Stack that is nested INSIDE each tab. This allows tabs to have their own headers and distinct histories. The root layout should often not have a header.
Set the 'headerShown' option to false on the tab layout
Use (group) routes to simplify the public URL structure
You may need to delete or refactor existing routes to fit this structure
Example structure:
app/
_layout.tsx — <Tabs />
(home)/
_layout.tsx — <Stack />
index.tsx — <ScrollView />
(settings)/
_layout.tsx — <Stack />
index.tsx — <ScrollView />
(home,settings)/
info.tsx — <ScrollView /> (shared across tabs)Array Routes for Multiple Stacks
Use array routes '(index,settings)' to create multiple stacks. This is useful for tabs that need to share screens across stacks.
app/
_layout.tsx — <Tabs />
(index,settings)/
_layout.tsx — <Stack />
index.tsx — <ScrollView />
settings.tsx — <ScrollView />This requires a specialized layout with explicit anchor routes:
// app/(index,settings)/_layout.tsx
import { useMemo } from "react";
import Stack from "expo-router/stack";
export const unstable_settings = {
index: { anchor: "index" },
settings: { anchor: "settings" },
};
export default function Layout({ segment }: { segment: string }) {
const screen = segment.match(/\((.*)\)/)?.[1]!;
const options = useMemo(() => {
switch (screen) {
case "index":
return { headerRight: () => <></> };
default:
return {};
}
}, [screen]);
return (
<Stack>
<Stack.Screen name={screen} options={options} />
</Stack>
);
}Complete App Structure Example
app/
_layout.tsx — <NativeTabs />
(index,search)/
_layout.tsx — <Stack />
index.tsx — Main list
search.tsx — Search view
i/[id].tsx — Detail page
components/
theme.tsx
list.tsx
utils/
storage.ts
use-search.tsLayout Files
Every directory can have a _layout.tsx file that wraps all routes in that directory:
// app/_layout.tsx
import { Stack } from "expo-router/stack";
export default function RootLayout() {
return <Stack />;
}// app/(tabs)/_layout.tsx
import { NativeTabs, Icon, Label } from "expo-router/unstable-native-tabs";
export default function TabLayout() {
return (
<NativeTabs>
<NativeTabs.Trigger name="index">
<Label>Home</Label>
<Icon sf="house.fill" />
</NativeTabs.Trigger>
</NativeTabs>
);
}Route Settings
Export unstable_settings to configure route behavior:
export const unstable_settings = {
anchor: "index",
};initialRouteNamewas renamed toanchorin v4
Not Found Routes
Create a +not-found.tsx file to handle unmatched routes:
// app/+not-found.tsx
import { Link } from "expo-router";
import { View, Text } from "react-native";
export default function NotFound() {
return (
<View>
<Text>Page not found</Text>
<Link href="/">Go home</Link>
</View>
);
