# Project Context

## Stack
- Node.js 22 with TypeScript 5.x
- Express.js for the API server
- Prisma ORM with PostgreSQL
- React 19 with Vite for the frontend

## Architecture
- Monorepo with pnpm workspaces
- packages/api — Express REST API
- packages/web — React SPA
- packages/shared — Shared types and utilities

## Commands
- pnpm dev — Start all services
- pnpm test — Run vitest across all packages
- pnpm lint — ESLint + Prettier check
- pnpm db:migrate — Run Prisma migrations

## Conventions
- Use barrel exports (index.ts) for public APIs
- Error responses use RFC 7807 Problem Details format
- All API endpoints require authentication except /health

# 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
