# 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

generating-lwc-components

Included

Lightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

document-processor-api

Included

Process documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.
