File-based routing in Expo Router maps your directory structure directly to URL routes. You create files and folders in your project to define the navigation hierarchy, simplifying app structure without manual route configuration.

Dynamic routes in Expo Router handle variable parameters using bracket syntax like `/user/[id]`. This pattern captures URL segments as parameters, allowing you to pass data programmatically to specific screens.

Configuring layouts in Expo Router involves defining root, tab, and modal configurations within your directory structure. This wraps nested screens in shared UI components, creating consistent navigation flows across your app.

You can secure screens with protected routes based on authentication status in Expo Router. This restricts unauthorized access and redirects unauthenticated users away from sensitive screens.

Setting up deep linking in Expo Router configures your app to handle external links pointing to specific app routes. This allows incoming URLs to navigate users directly to the correct screen within your React Native application.
