# React Component Standards

## Purpose
Ensure consistent React component patterns across the frontend codebase.

## Priority
High

## Instructions
- Use functional components with TypeScript
- Define props interfaces above the component
- Use React.FC only when children are expected
- Colocate styles using CSS Modules (*.module.css)
- Extract hooks into separate files when reused
- Memoize expensive computations with useMemo
- Use React.lazy for route-level code splitting

# PearAI Project Rules

## Framework
- Next.js 15 App Router with TypeScript
- Drizzle ORM with PostgreSQL
- TailwindCSS v4 for styling

## Patterns
- Use server actions for mutations
- Colocate loading.tsx and error.tsx with page routes
- Prefer RSC; add "use client" only when needed

## Naming
- Components: PascalCase (UserProfile.tsx)
- Utilities: camelCase (formatDate.ts)
- Database tables: snake_case

## Dependencies
- Do NOT add new dependencies without asking
- Use date-fns for date manipulation
- Use zod for all validation

## Commands
- Dev: pnpm dev
- Build: pnpm build
- Lint: pnpm lint
