## Overview

Velora is a full-stack storefront and administration platform: customers browse and search products, manage carts and wishlists, check out, and track orders; administrators manage catalog, users, and order operations. React routes and shared contexts call REST services, while Spring controllers implement API behavior and repositories persist domain data. The README documents MySQL and the broader feature set; source excerpts substantiate selected frontend wiring and backend calls, but not every controller or integration.

Main entry points: [`ECommerceApplication Backend/src/main/java/com/velora/velora_backend/controllers/OrderController.java`](https://github.com/itizzakir/ecommerceapplication/blob/main/ECommerceApplication%20Backend/src/main/java/com/velora/velora_backend/controllers/OrderController.java) (Order and checkout API), [`ECommerceApplication Frontend/src/routes/AppRouter.jsx`](https://github.com/itizzakir/ecommerceapplication/blob/main/ECommerceApplication%20Frontend/src/routes/AppRouter.jsx) (Route dispatch), [`ECommerceApplication Frontend/src/services`](https://github.com/itizzakir/ecommerceapplication/tree/main/ECommerceApplication%20Frontend/src/services) (API services), [`ECommerceApplication Backend/src/main/java/com/velora/velora_backend/controllers/AuthController.java`](https://github.com/itizzakir/ecommerceapplication/blob/main/ECommerceApplication%20Backend/src/main/java/com/velora/velora_backend/controllers/AuthController.java) (Authentication API)
