一覽

Next.js Commerce is the skill of building end-to-end online stores using Next.js 13+, Stripe, Vercel, and a product database. Used by startups and mid-market SaaS to sell digital and physical goods. Senior practitioners earn 30-40% premium because they design systems handling 10k+ transactions/day. Time to mastery: 8-12 weeks. Sits between full-stack Next.js and Stripe integration.

什麼是 Next.js Commerce

Next.js Commerce is the architecture and practice of building full-stack e-commerce platforms using Next.js 13+, TypeScript, Stripe, and a relational database (PostgreSQL). It covers the entire stack: product pages, shopping cart, checkout flow, payment processing, order management, and customer accounts. Unlike traditional monoliths or Shopify themes, Next.js Commerce gives you raw control over UX, integrations, and scaling. You own the server logic (inventory management, pricing rules, taxes), client rendering (fast product pages, cart state), and payment flow (Stripe webhooks, idempotency).

❓ 常見問題

Should I build custom or use Shopify/WooCommerce?
Custom (Next.js) if: unique UX, high transaction volume, custom integrations. Shopify if: launching fast, need plugins, limited technical resources. Next.js = more control but 3-5x more dev time.
How do I handle inventory sync?
Inventory source of truth lives in database (PostgreSQL with Prisma). Update on purchase completion. For multi-channel (web + mobile app), use a message queue (Bull/Agenda) to sync inventory 50ms after purchase.
What about payment retry logic?
Stripe webhook for payment.succeeded. Retry logic via Stripe (automatic retries 3 days post-failure). You listen for payment.failed and notify customer. Never retry manually, Stripe handles it.
How do I prevent double-charging?
Idempotency keys. Every purchase attempt gets a UUID. If retry happens, same UUID prevents duplicate charge. Stripe native support: pass idempotencyKey in request.
What about international payments?
Stripe handles 135+ countries. Localize currency display. Handle tax (Stripe Tax API). Currency conversion = Stripe's job, not yours. Test with test cards per country.
