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.
