# 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

# Code Standards

## TypeScript
- Enable strict mode in all tsconfig files
- No `any` types — use `unknown` and narrow
- Prefer interfaces over type aliases for object shapes

## React
- Functional components only
- Use custom hooks for shared stateful logic
- Colocate component, styles, and tests

## Git
- Conventional commits (feat:, fix:, chore:, etc.)
- Keep commits atomic and focused
- Squash merge feature branches

KEY DIFFERENCES

1. IDE integration

Replit: Platform. Roo Code: Supported.

WHICH SHOULD I USE?

Recommendation

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