E-Commerce Application (MERN Stack)

This is a modern full-stack E-Commerce application built using the MERN stack (MongoDB, Express, React, Node.js). It includes authentication with JSON Web Tokens (JWT), role-based authorization (Admin & User access control), password hashing, and concurrent client-server execution.

---

🚀 Features

• User Authentication: Secure registration, login, and forgot password flows.
• Security: Password hashing using bcrypt and token-based authentication via jsonwebtoken.
• Role-based Access Control: Route protections for standard Users and Admin users.
• Concurrent Development: Run both the Express backend and React frontend with a single command.
