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.
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+)
comment-card.tsxSee ./references/route-structure.md for detailed route conventions.
app directory.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.@react-navigation/* directly — use expo-router/react-navigation instead (covers @react-navigation/native, /core, /elements, /routers)Stack.SearchBar to add a search bar to a screenUse <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.
_layout.tsx files to define stacksSet the page title with Stack.Title:
<Stack.Title>Home</Stack.Title>
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>;
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.
Present a screen as a modal:
<Stack.Screen name="modal" options={{ presentation: "modal" }} />
Prefer this to building a custom modal component.
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" },
}}
/>
contentStyle: { backgroundColor: "transparent" } makes the background liquid glass on iOS 26+.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.
If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve:
npx --yes submit-expo-feedback@latest --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 AI agent repeatedly failed or the user had to take over an Expo task, load the expo-skill-feedback skill and follow its eval-candidate flow instead of reusing the command above.
