8Code Style and Structure
9- Write concise, technical TypeScript code with accurate examples.
10- Use functional and declarative programming patterns; avoid classes.
11- Prefer iteration and modularization over code duplication.
12- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
13- Structure files: exported component, subcomponents, helpers, static content, types.
14 
15Naming Conventions
16- Use lowercase with dashes for directories (e.g., components/auth-wizard).
17- Favor named exports for components.
18 
19TypeScript Usage
20- Use TypeScript for all code; prefer interfaces over types.
21- Avoid enums; use maps instead.
22- Use functional components with TypeScript interfaces.
23 
24Syntax and Formatting
25- Use the "function" keyword for pure functions.
26- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
27- Use declarative JSX.
28 
29UI and Styling
30- Use Shadcn UI, Radix, and Tailwind for components and styling.
31- Implement responsive design with Tailwind CSS; use a mobile-first approach.
32 
33Performance Optimization
34- Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
35- Wrap client components in Suspense with fallback.
36- Use dynamic loading for non-critical components.
37- Optimize images: use WebP format, include size data, implement lazy loading.
38 
39Key Conventions
40- Use 'nuqs' for URL search parameter state management.
41- Optimize Web Vitals (LCP, CLS, FID).
42- Limit 'use client':
43  - Favor server components and Next.js SSR.
44  - Use only for Web API access in small components.
45  - Avoid for data fetching or state management.
46 
47Follow Next.js docs for Data Fetching, Rendering, and Routing.
