Awesome Cursor Rules Collection

You are an expert in TypeScript, React Native, Expo, and Mobile UI development.

Code Style and Structure:

- Write concise, type-safe TypeScript code.
- Write Clean, Readable Code: Ensure your code is easy to read and understand. Use descriptive names for variables and functions.
- Use Functional Components: Prefer functional components with hooks (useState, useEffect, etc.) over class components.
- Component Modularity: Break down components into smaller, reusable pieces. Keep components focused on a single responsibility.
  - Ensure components are modular, reusable, and maintainable.
- Organize Files by Feature: Group related components, hooks, and styles into feature-based directories (e.g., user-profile, chat-screen).
  - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
  - Structure files: exported component, subcomponents, helpers, static content, types.

Naming Conventions:

- Variables and Functions: Use camelCase for variables and functions (e.g., isFetchingData, handleUserInput).
- Components: Use PascalCase for component names (e.g., UserProfile, ChatScreen).
- Directories: Use lowercase and hyphenated names for directories (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 using `any`; strive for precise types.
- Avoid Global Variables: Minimize the use of global variables to prevent unintended side effects.
- Use ES6+ Features: Leverage ES6+ features like arrow functions, destructuring, and template literals to write concise code.
- Use TypeScript for all code; prefer types over interfaces.
- Avoid enums; use maps instead.
- Use functional components with TypeScript types.
- Use strict mode in TypeScript for better type safety.

  Syntax and Formatting

  - Use the "function" keyword for pure functions.

Performance Optimization:

- Minimize the usage of `useEffect`, `useState`, and heavy computations inside render methods.
- Optimize State Management: Avoid unnecessary state updates and use local state only when needed.

  - Use Expo's AppLoading and SplashScreen for optimized app startup experience.
  - Optimize images: use WebP format where supported, include size data, implement lazy loading with expo-image.
  - Implement code splitting and lazy loading for non-critical components with React's Suspense and dynamic imports.

    - Profile and monitor performance using React Native's built-in tools and Expo's debugging features.

  - Avoid unnecessary re-renders by memoizing components and using useMemo and useCallback hooks appropriately.

- Prefer FlashList over FlatList for better performance
- FlatList Optimization: Optimize FlatList with props like removeClippedSubviews, maxToRenderPerBatch, and windowSize.
- Avoid Anonymous Functions: Refrain from using anonymous functions in renderItem or event handlers to prevent re-renders.
- use tanStack query for api calls
- use react navigation v6

UI and Styling:

- Consistent Styling: Use StyleSheet.create() for consistent styling or Styled Components for dynamic styles.
- Responsive Design: Ensure your design adapts to various screen sizes and orientations. Consider using responsive units and libraries like react-native-responsive-screen.
- Optimize Image Handling: Use optimized image libraries like @candlefinance/faster-image to handle images efficiently. Refer to the official documentation for setup and usage: https://github.com/candlefinance/faster-image
- use react native paper for UI components
  - Ensure high accessibility (a11y) standards using ARIA roles and native accessibility props.
  - Leverage react-native-reanimated and react-native-gesture-handler for performant animations and gestures.

Best Practices:

- Follow React Native's Threading Model: Be aware of how React Native handles threading to ensure smooth UI performance.
- Use Expo Tools: Utilize Expo's EAS Build and Updates for continuous deployment and Over-The-Air (OTA) updates.

Safe Area Management

- Use SafeAreaProvider from react-native-safe-area-context to manage safe areas globally in your app.
- Wrap top-level components with SafeAreaView to handle notches, status bars, and other screen insets on both iOS and Android.
- Use SafeAreaScrollView for scrollable content to ensure it respects safe area boundaries.
- Avoid hardcoding padding or margins for safe areas; rely on SafeAreaView and context hooks.

Navigation

- Use React Navigation for handling navigation and deep linking with best practices.
- Leverage deep linking and universal links for better user engagement and navigation flow.

  State Management

  - Use React Context and useReducer for managing global state.
  - Leverage react-query for data fetching and caching; avoid excessive API calls.
  - For complex state management, consider using Zustand.
  - Handle URL search parameters using libraries like expo-linking.

Error Handling and Validation

- Use Zod for runtime validation and error handling.
- Implement proper error logging using Sentry or a similar service.
- Prioritize error handling and edge cases:

  - Handle errors at the beginning of functions.
  - Use early returns for error conditions to avoid deeply nested if statements.
  - Avoid unnecessary else statements; use if-return pattern instead.
  - Implement global error boundaries to catch and handle unexpected errors.

  Testing

  - Write unit tests using Jest and React Native Testing Library.
  - Implement integration tests for critical user flows using Detox.
  - Use Expo's testing tools for running tests in different environments.
  - Consider snapshot testing for components to ensure UI consistency.

Security

- Sanitize user inputs to prevent XSS attacks.
- Implement secure authentication mechanisms with HTTPS and secure cookies.
- Use expo-secure-store for secure storage of sensitive information.
- Implement rate limiting and throttling to prevent abuse.
- Use HTTPS for all network requests to prevent man-in-the-middle attacks.
- Implement secure session management and token expiration.
- Use expo-crypto for secure encryption and decryption.
- Implement secure logging and monitoring for security incidents.

  Internationalization (i18n)

  - Use react-native-i18n or expo-localization for internationalization and localization.
  - Support multiple languages and RTL layouts.
  - Ensure text scaling and font adjustments for accessibility.

Key Conventions

1. Rely on Expo's managed workflow for streamlined development and deployment.
2. Prioritize Mobile Web Vitals (Load Time, Jank, and Responsiveness).
3. Use expo-constants for managing environment variables and configuration.
4. Use expo-permissions to handle device permissions gracefully.
5. Implement expo-updates for over-the-air (OTA) updates.
6. Follow Expo's best practices for app deployment and publishing: https://docs.expo.dev/distribution/introduction/
7. Ensure compatibility with iOS and Android by testing extensively on both platforms.

# TrailMates Profile Image Storage Rules

## Profile Image Storage Hierarchy
1. Remote Storage (Firebase)
   - profileImageUrl: Primary full-size image URL
   - profileThumbnailUrl: Optimized thumbnail URL
   - These URLs are the source of truth when available

2. Local Storage (SwiftData)
   - @Attribute(.externalStorage) profileImageData: Binary image data
   - Stored outside main database for performance
   - Used for offline access and caching

3. In-Memory (Computed)
   - profileImage: UIImage computed property
   - Provides convenient UIImage interface
   - Automatically manages conversion to/from Data

## Data Flow Rules
1. Image Upload
   - Set profileImage (converts to profileImageData)
   - Upload to Firebase
   - Clear local data
   - Store remote URLs

2. Image Download
   - Try remote URLs first (AsyncImage)
   - Fall back to local data if offline
   - Cache as needed

3. Offline Mode
   - Use profileImageData
   - Sync when online resumes

## SwiftData Integration
1. External Storage
   - Large binary data stored separately
   - Automatic cleanup by SwiftData
   - Better performance than inline storage

2. Model Requirements
   - User must be final class
   - @Model attribute required
   - Codable conformance maintained

## Validation Rules
1. Location Coordinates
   - Both latitude and longitude required if either present
   - Throws error if only one coordinate provided

2. Image Data
   - JPEG compression at 0.8 quality
   - Thumbnail generation handled by Firebase

## Equality Comparison
All properties compared including:
- Profile image data
- Remote URLs
- Location coordinates
- Optional properties
