React Native Cursor Rules

Expert guidelines for React Native development by Will Sims, focusing on type-safe TypeScript code, performance optimization, and maintainable component architecture.

Code Style and Structure

• Write concise, type-safe TypeScript code
• Use functional components and hooks instead of class components
• Ensure components are modular, reusable, and maintainable
• Organize files by feature, grouping related components, hooks, and styles

Naming Conventions

• Use camelCase for variables and functions (e.g., isFetchingData, handleUserInput)
• Use PascalCase for components (e.g., UserProfile, ChatScreen)
• Directory names should be lowercase and hyphenated (e.g., user-profile, chat-screen)

TypeScript Usage

• Use TypeScript for all components, favoring interfaces for props and state
• Enable strict typing in tsconfig.json
• Avoid any type; strive for precise types
• Utilize React.FC for defining functional components with props

Performance Optimization

• Minimize useEffect, useState, and heavy computations in render methods
• Use React.memo() for components with static props to prevent unnecessary re-renders
• Optimize FlatLists with the following props:
  • removeClippedSubviews
  • maxToRenderPerBatch
  • windowSize
• Use getItemLayout for consistent-sized FlatList items
• Avoid anonymous functions in renderItem or event handlers

UI and Styling

• Use consistent styling via StyleSheet.create() or Styled Components
• Ensure responsive design for different screen sizes and orientations
• Optimize images using react-native-fast-image

Best Practices

• Follow React Native's threading model for smooth performance
• Utilize Expo's EAS Build and Over-The-Air updates
• Use React Navigation for navigation and deep linking
