Static generation (ISR)	Lightning-fast product pages with auto-refresh
API Routes	Backend logic without a separate server
Image optimization	Automatic WebP, lazy loading, responsive sizes
Edge functions	Fast global response times
Vercel deployment	One-click deploy with SSL and CDN

Key Implementation Patterns

Product Pages with ISR

Use Incremental Static Regeneration to pre-render product pages at build time and revalidate every 60 seconds:

Generate static pages for all products at build time
Set revalidate: 60 so pages refresh every minute
New products appear without a full rebuild
Google crawls fully-rendered HTML (great for SEO)

Cart State Management

For MVP, use React Context + localStorage:

CartProvider wraps the app, holds cart items in state
Cart persists across page refreshes via localStorage
Cart items: { productId, title, price, quantity, image }
Cart operations: add, remove, update quantity, clear

Checkout with Stripe

User clicks "Checkout" on cart page
Frontend sends cart items to /api/checkout
API creates Stripe Checkout Session with line items
User is redirected to Stripe's hosted checkout
After payment, redirected to /checkout/success
Webhook creates order in database

SEO Optimization

Page	SEO Strategy
Homepage	Target brand keywords, featured products
Category pages	Target category keywords, unique descriptions
Product pages	Product name as title, rich meta descriptions, Product schema
Blog	Educational content for top-of-funnel traffic

Product Schema (JSON-LD)

Add structured data to product pages for rich search results with price, availability, and ratings.

Performance Checklist

Images: Next.js <Image> component with WebP and lazy loading
Fonts: next/font for zero layout shift
JavaScript: Dynamic imports for below-the-fold components
CSS: Tailwind CSS (purged unused styles)
Caching: ISR for product pages, SWR for cart state
Target: Core Web Vitals all green
