User Management System

Overview

FLIES is a full-stack web application built with React (Material UI) for the frontend and Go (Gin) for the backend. It provides authentication, role-based access control, and user management capabilities.

Technologies Used

Frontend (React.js)

• React.js with Material UI
• React Router for navigation
• Axios for API requests
• JWT Authentication for secure access

Backend (Go)

• Go (Golang) for the backend API
• Gin Framework for routing and middleware
• GORM for database management
• PostgreSQL as the database
• JWT Authentication for secure user sessions

User Roles & Permissions

Role	Permissions
User	View Profile
Admin	Manage Users, Change Roles, Delete Users (except Admins)

Installation and Setup

Backend (Go)

1. Clone the repository:

git clone https://github.com/your-repo/user-management.git
cd user-management/backend

2. Install dependencies:

go mod tidy

3. Configure environment variables in .env:

DATABASE_URL=your_postgres_connection_string
JWT_SECRET=your_secret_key

4. Run the server:

go run main.go

Frontend (React)

1. Navigate to the frontend directory:

cd ../frontend

2. Install dependencies:

npm install

3. Start the development server:

npm start

API Endpoints

Authentication

• POST /login - User login (returns JWT token)
• POST /register - Register a new user

Users (Admin Only)

• GET /users - Get all users
• PATCH /users/:id/role - Update user role (Admin cannot change their own role)
• DELETE /users/:id - Delete a user (Admins cannot be deleted)

User Profile

• GET /profile - Get current user profile
• PATCH /profile - Update user details

Security Considerations

• JWT Storage: Stored in localStorage for persistence.
• Token Expiry: Tokens expire after X hours (define if necessary).
• Role Protection: Admin roles cannot be modified or removed.
