Shopify

Build me a small self-hosted shop for a handful of products, the honest small slice of Shopify. Requirements: - Node + Express + better-sqlite3 on a VPS; products in products.json (slug, name, price, images, stock count), server-rendered catalog and product pages. - Cart in a session cookie; checkout hands off entirely to Stripe Checkout (keys in .env). Never touch card data. - Stripe webhook records the order, decrements stock, and emails me and the buyer via Resend (key in .env). - An /admin page behind basic auth: order list and a mark-shipped button that emails the buyer with an optional tracking number. - Flat shipping rates per region in a config file; sold-out products stay visible but cannot be bought. - No customer accounts, no telemetry; orders stay in my SQLite file. - Out of scope: discount engines, multi-currency, POS, and tax automation. Use Stripe Tax for tax; do not write tax logic. - README: Stripe webhook setup, a plain warning that I am now the fraud department, and a note that this is not Shopify, whose trusted checkout, payment risk handling, and app ecosystem cannot be rebuilt; if volume grows, move to Shopify or Medusa rather than growing this.
