Code Style and Structure Write concise, technical TypeScript code with accurate examples Employ functional and declarative programming patterns; steer clear of classes Prioritize iteration and modularization over code duplication Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError) Organize 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 declarative JSX UI and Styling Leverage Shadcn UI, Radix, and Tailwind for components and styling Implement responsive design with Tailwind CSS using a mobile-first approach Performance Optimization Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components 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' to Web API access in small components; avoid for data fetching or state management Follow Next.js documentation for Data Fetching, Rendering, and Routing
