# 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

# My Project

## Overview
This is a Next.js e-commerce storefront with Stripe payments, NextAuth
authentication, and a PostgreSQL database via Prisma ORM.

## Tech Stack
- Framework: Next.js 14 (App Router, server components by default)
- Database: PostgreSQL with Prisma ORM
- Auth: NextAuth.js with GitHub and Google providers
- Payments: Stripe Checkout and webhooks
- Styling: Tailwind CSS with shadcn/ui components

## Development Phase
Currently building the product catalog and cart system. Authentication
and payment flows are complete. Next up: order history and admin dashboard.

## Code Style
- TypeScript strict mode enabled
- Prefer server components; use "use client" only when needed
- Use server actions for mutations (app/actions/)
- Validate all inputs with Zod schemas

## Commands
- `npm run dev` — start development server on port 3000
- `npm run build` — production build
- `npm run db:push` — push Prisma schema to database
- `npm run db:seed` — seed database with sample data
- `npm test` — run Jest test suite

Amazon Q Developer: Supported. Replit: Not supported.

2. IDE integration

Amazon Q Developer: CLI. Replit: Platform.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Amazon Q Developer, configure .amazonq/rules/*.md. If you use Replit, configure replit.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
