AutoGineer summary

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.

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.

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:

<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.
