Frontend Stack

• React 18 - Modern UI library
• TypeScript - Type safety
• Vite - Lightning-fast build tool
• React Router - Client-side routing
• Axios - HTTP client with interceptors
• Tailwind CSS - Utility-first styling

Backend Stack

• Node.js + Express - Web server
• TypeScript - Type safety
• Prisma ORM - Type-safe database access
• PostgreSQL - Production database
• JWT - Authentication
• Zod - Request validation

🚀 Quick Start

Automated Setup (Recommended)

./setup.sh

Manual Setup

1. Install Dependencies

Frontend:

cd frontend
npm install

Backend:

cd backend
npm install

2. Configure Environment

Backend: Update backend/.env:

PORT=3000
DATABASE_URL="postgresql://user:password@localhost:5432/skyartshop"
JWT_SECRET=your-secret-key
CORS_ORIGIN=http://localhost:5173

Frontend: Update frontend/.env:

VITE_API_URL=http://localhost:3000/api

3. Set Up Database

cd backend
npx prisma generate
npx prisma migrate dev

4. Start Development Servers

Terminal 1 - Backend:

cd backend
npm run dev
# Runs on http://localhost:3000

Terminal 2 - Frontend:

cd frontend
npm run dev
# Runs on http://localhost:5173

📝 How to Add a New Feature

See docs/ARCHITECTURE.md for a complete step-by-step guide on adding the "Wishlist" feature.

Quick Overview

Backend:

1. Update Prisma schema
2. Create service (business logic)
3. Create controller (request handler)
4. Add routes
5. Add validation

Frontend:

1. Add TypeScript types
2. Create API client methods
3. Create custom hook (optional)
4. Use in components

---

🔐 Security

• JWT authentication on protected endpoints
• Password hashing with bcrypt
• Input validation with Zod
• Security headers with Helmet
• CORS configured for specific origins
• SQL injection prevention via Prisma
• Client-side route protection

---

🧪 Testing
