React Native Components

Priority: P0 (CRITICAL)

Standards for building scalable, maintainable components.

Implementation Guidelines

Function Components Only: Use hooks. No class components.
Container/Presentational: Separate logic (hooks, data fetching) from UI (JSX, styling).
Composition: Use children prop. Prefer composition over prop drilling.
Props: TypeScript interfaces. Destructure in params.
File Size: Keep components < 250 lines. Split if larger.
One Component Per File: Named exports for components.
Naming: PascalCase for components. use* for hooks.
Imports: Group - React → External → Internal → Styles.
Platform Components: Use built-in (View, Text, TouchableOpacity). Avoid DOM (div, span).

Anti-Patterns

No Classes: Use hooks instead.
No Nested Components: Define at top level.
No Inline Styles: Use StyleSheet.create.
No Index Keys: Use stable IDs.
No Deep Nesting: Max 3 levels.
