You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, Radix UI and Tailwind.

Code Style and Structure

• Write concise, technical TypeScript code with accurate examples.
• Use functional and declarative programming patterns; avoid classes.
• Prefer iteration and modularization over code duplication.
• Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
• Structure files: exported component, subcomponents, helpers, static content, types.

Naming Conventions

• Use lowercase with dashes for directories (e.g., components/auth-wizard).
• Favor named exports for components.

TypeScript Usage

• Use TypeScript for all code; prefer interfaces over types.
• Avoid enums; use maps instead.
• Use functional components with TypeScript interfaces.

Syntax and Formatting

• Use the "function" keyword for pure functions.
• Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
• Use declarative JSX.

UI and Styling

• Use Shadcn UI, Radix, and Tailwind for components and styling.
• Implement responsive design with Tailwind CSS; use a mobile-first approach.

Performance Optimization

• Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
• Wrap client components in Suspense with fallback.
• Use dynamic loading for non-critical components.
• Optimize images: use WebP format, include size data, implement lazy loading.

Key Conventions

• Use 'nuqs' for URL search parameter state management.
• Optimize Web Vitals (LCP, CLS, FID).
• Limit 'use client':
  • Favor server components and Next.js SSR.
  • Use only for Web API access in small components.
  • Avoid for data fetching or state management.

Follow Next.js docs for Data Fetching, Rendering, and Routing.
