Guide detailing Next.js 14+ App Router patterns, emphasizing Server Components, ISR caching, middleware, server actions, and parallel routes to build scalable, data-driven apps with minimal client JS.

This guide provides expert patterns for implementing secure, full-stack authentication in Next.js using Supabase. It covers essential architectural components, including setting up separate browser and server clients, utilizing middleware for route protection and session refreshing, handling OAuth callbacks, and implementing auth operations safely via Server Actions and Server Components. Essential knowledge for building secure, modern web applications.

Runs automated visual regression tests via Percy, Chromatic, or BackstopJS to capture component or page screenshots, compare them against baselines, and flag unintended UI changes during feature updates or CI/CD runs.

This guide details the standardized directory structure and best practices for building robust and maintainable plugins for Claude Code. It covers critical components including the plugin manifest (plugin.json), commands, agents, skills, and hooks. Use this skill when you need to scaffold a new plugin, understand the required component organization, or configure the plugin's architecture according to best practices.

Guides building accessible Radix UI design systems using headless primitives, focusing on theming, composition, keyboard navigation and WCAG compliance for custom component libraries in React-based apps.

A comprehensive guide maintained by Vercel for optimizing performance in React and Next.js applications. It covers critical rules across multiple categories, including eliminating waterfalls, bundle size optimization, server-side caching, and granular control over client-side rendering and data fetching. Use this when building new components or refactoring existing code for maximum speed and efficiency.

Automated assistance for building React components, offering best practices, production-ready code generation, and validation guidance for frontend patterns like accessibility and performance optimization.

This guide outlines best practices for building highly flexible and maintainable React components. It addresses common architectural pitfalls, such as 'boolean prop proliferation,' by recommending advanced patterns like compound components, state lifting, and context providers. Use this when refactoring large component libraries, designing robust APIs, or reviewing component architecture, including considerations for React 19 APIs.

A specialist skill for building robust, scalable, and high-performance React applications. Expertise covers modern patterns including React 19, Server Components (RSC), Next.js App Router, and advanced state management (Redux/Zustand). Ideal for implementing complex features, optimizing rendering, and adhering to strict TypeScript/accessibility standards.

Defines how to create React Flow node components using shared templates with TypeScript typings, store hooks, and canvas registration so you can add consistent, editable nodes to your app.

This skill guides the process of modernizing React applications. It covers crucial tasks such as major version upgrades, migrating from class components to functional components using hooks, adopting advanced concurrent features (like Suspense), and utilizing codemods for automated, large-scale code transformation. Ideal for maintaining and scaling complex React codebases.
