SOLID principles for React 19. Files < 100 lines, hooks separated, interfaces in src/interfaces/, JSDoc mandatory. Use for React architecture and code quality.
React Native with Expo framework for building native mobile apps on Android, iOS, and web from a single TypeScript codebase. Covers Expo Router file-based navigation (stack, tabs, drawer), EAS Build/Submit/Update for CI/CD and OTA updates, expo-dev-client for custom development builds, Expo Modules API for native Swift/Kotlin modules, core RN patterns (StyleSheet, FlatList, Platform-specific code), native device APIs (camera, notifications, haptics), and NativeWind for Tailwind CSS styling. Use when building React Native apps with Expo, configuring Expo Router navigation, setting up EAS Build pipelines, implementing OTA updates, creating native modules, or integrating device APIs like camera and push notifications.
Universal coding standards, best practices, and patterns for TypeScript, JavaScript, React, and Node.js development.
Diagnose and fix React Native & Expo codebase health issues. Use when reviewing React Native code, fixing performance problems, auditing accessibility, or improving architecture.
Build and maintain React Native apps with Expo SDK, EAS Build, EAS Update, and Continuous Native Generation. Use when configuring Expo projects, adding native modules, building binaries, or shipping over-the-air updates.
Full Sentry SDK setup for React Native and Expo. Use when asked to "add Sentry to React Native", "install @sentry/react-native", "setup Sentry in Expo", or configure error monitoring, tracing, profiling, session replay, or logging for React Native applications. Supports Expo managed, Expo bare, and vanilla React Native.
Application-level React performance optimization covering React Compiler mastery, bundle optimization, rendering performance, data fetching, Core Web Vitals, state subscriptions, profiling, and memory management. Use when optimizing React app performance, analyzing bundle size, improving Core Web Vitals, or profiling render bottlenecks. Complements the react skill (API-level patterns) with holistic performance strategies. Does NOT cover React 19 API usage (see react skill) or Next.js-specific features (see nextjs-16-app-router skill).
Testing Library for React 19 - render, screen, userEvent, waitFor, Suspense. Use when writing tests for React components with Vitest.
Best practices for developing tools, dashboards and interactive data apps with HoloViz Panel. Create reactive, component-based UIs with widgets, layouts, templates, and real-time updates. Use when developing interactive data exploration tools, dashboards, data apps, or any interactive Python web application. Supports file uploads, streaming data, multi-page apps, and integration with HoloViews, hvPlot, Pandas, Polars, DuckDB and the rest of the HoloViz and PyData ecosystems.
Comprehensive UI/UX guidelines for building React/Next.js components with Ant Design, shadcn/ui charts, and consistent styling. Use when creating forms, tables, modals, cards, or any UI component. Enforces color palette, typography, spacing (8px/12px/16px/24px), animations, and component patterns specific to the application.
Enterprise shadcn/ui Component Library with AI-powered design system architecture, Context7 integration, and intelligent component orchestration for modern React applications
