Build reusable UI components for Expo Router by applying native-first design principles, compound patterns, and platform-aware overrides to ensure consistent behavior across iOS, Android, and web. Use design tokens and CSS variables to maintain cohesive theming across your portable primitives.

Compound components are composable UI primitives that enable flexible screen composition while maintaining cohesive behavior. In native-first UI design, they allow developers to build portable components that share state internally without prop drilling across iOS, Android, and web platforms.

Add accessibility to portable UI components by implementing built-in keyboard support and safe area handling. These accessible defaults ensure your native-first Expo Router primitives remain usable across iOS, Android, and web without requiring additional manual configuration.

Yes, you can use design tokens and CSS variables to theme Expo Router components. Specifying design tokens in your global CSS ensures consistent theming and behavior across portable UI components, allowing you to adapt tokens easily for different platform overrides.

The best way to share UI components across multiple Expo projects is creating copy-paste ready portable primitives. Drop these native-first components directly into your src/components/ui/ directory and compose them in your screens using standard Expo CLI workflows.

No external dependencies are required to create portable native-first UI components. The guidelines leverage Expo Router primitives, compound patterns, and platform-specific overrides natively, relying solely on design tokens and CSS variables for consistent cross-platform theming.
