User Management API

Project Summary

A backend service built with Node.js, Express, and MongoDB (using Mongoose). The service provides a robust RESTful API for managing users and products while ensuring secure authentication and role-based access control. A simple dashboard is also included to help manage data visually.

Features

• User & Product Management:
  • Full CRUD operations for users and products.
• Secure Authentication:
  • Uses JSON Web Tokens (JWT) for authentication.
  • Passwords are securely hashed with bcrypt.
• Role-Based Access Control:
  • Enforces different access levels (Admin, Seller, Customer) for various endpoints.
• Clean and Modular Architecture:
  • Easy to extend and maintain.

Tech Stack

• Backend: Node.js, Express.js
• Frontend: Ejs
• Database: MongoDB with Mongoose
• Authentication: JWT, bcrypt.js
• Utilities: dotenv, nodemon, morgan, cors
