How rainel0421/e-commerce-backend works

This is an Express e-commerce API: clients browse products and categories, manage carts, authenticate, and place orders; checkout and payment confirmation complete the purchase. Admin routes provide product, category, and order management, while uploads and Stripe webhooks support commerce operations. The sampled code confirms routing through controllers, services, and repositories for products, categories, and authentication, plus the order webhook path. Cart, upload, and several service/repository internals are represented from the tree and route wiring, but their exact internal calls were not sampled.
