React, Off the Web
File-based navigation with expo-router
Lesson 2 of 5
The app/ directory is your navigation tree — stacks and tabs come from _layout files, params from [bracket] segments.
What you'll learn
- Map files in app/ to screens, exactly like Next.js routes map to pages
- Compose Stack and Tabs navigators with _layout files and route groups
- Navigate with Link and read dynamic segments via useLocalSearchParams
