## Overview

The Shopping App is a MERN storefront and order-tracking system. Customers browse products, manage a cart and addresses, place orders, and follow fulfillment; sellers manage products and mark orders shipped, while shippers deliver them and admins manage roles and catalog permissions. The graph separates the React experience, API routing and controllers, and MongoDB models. README documents the role-based lifecycle and additional facilities; unsampled frontend actions and several backend handlers limit which cross-layer calls can be verified.

Main entry points: [`controllers/orderController.js`](https://github.com/moelashmawy/inventory-application/blob/master/controllers/orderController.js) (Order lifecycle), [`views/src/App.js`](https://github.com/moelashmawy/inventory-application/blob/master/views/src/App.js) (Application routes), [`server.js`](https://github.com/moelashmawy/inventory-application/blob/master/server.js) (HTTP server), [`controllers/permissionsController.js`](https://github.com/moelashmawy/inventory-application/blob/master/controllers/permissionsController.js) (Role administration)
