An online store is the most unforgiving thing you can build. The cart must never lose an item. The webhook may arrive twice. Two customers will race for the last unit in stock. And none of it may fail on the busiest day of the year.
Across 301 pages you build **ShopFlow**, a complete Django e-commerce platform — and you build it the way a store that handles real money has to be built.
**What's inside**
- Catalog and product variants that don't collapse under real-world data
- A storefront people can actually navigate: search, filters, categories
- A cart that survives sessions, logins and tab-closing
- Checkout with Stripe: payment intents, 3-D Secure, and failure paths
- Webhooks done right — idempotency, replay, and the double-charge you must prevent
- Orders, fulfilment and customer accounts
- Inventory with concurrency safety: how two buyers don't get the same last item
- Discounts, coupons and promotions
- The admin the shop owner will actually use
- Security, performance, deployment — and how to survive a traffic spike
Every chapter closes with a summary and key takeaways. Five appendices cover a launch checklist, a Stripe reference, a security checklist, a glossary and further reading.
