Role-Based Access Control (RBAC) Web Application

This project is a Role-Based Access Control (RBAC) web application built using the MERN stack (MongoDB, Express, React, Node.js). The application includes user authentication, role-based authorization, and secured routes.

It demonstrates scalable, secure, and efficient handling of user roles and permissions.

Features

Authentication & Authorization

• User Registration: Users can register with a username, email, password, and role (e.g., User, Admin, Moderator).
• User Login: Secure login using JWT-based authentication.
• Role-Based Access Control:
  • Admin can access and manage all routes.
  • Users have limited access based on their roles.

Key Functionalities

• Logout: Users can securely log out from the application.
• Protected Routes: Role-specific routes are implemented for secure navigation.
• Dynamic Role Selection: Role assignment during registration.

User Roles

1. Admin:
   • Full access to all routes.
2. Moderator:
   • Limited access based on business requirements.
3. User:
   • Basic access to user-specific routes.
