# 🔐 Simple User Management System
|
|
|
|
## ✅ What We Built
|
|
|
|
A **lightweight, persistent user management system** that extends your existing OAuth2 authentication using your existing JSON data storage.
|
|
|
|
## 🎯 Key Features
|
|
|
|
### ✅ **Persistent Storage**
|
|
- Uses your existing JSON data file storage
|
|
- No third-party services required
|
|
- Completely self-contained
|
|
- Users preserved across server restarts
|
|
|
|
### 🔧 **New API Endpoints**
|
|
- `GET /auth/users` - List all users (admin only)
|
|
- `PATCH /auth/users/:email/role` - Update user role (admin only)
|
|
- `DELETE /auth/users/:email` - Delete user (admin only)
|
|
- `GET /auth/users/:email` - Get specific user (admin only)
|
|
|
|
### 🎨 **Admin Interface**
|
|
- Beautiful React component for user management
|
|
- Role-based access control (admin only)
|
|
- Change user roles with dropdown
|
|
- Delete users with confirmation
|
|
- Responsive design
|
|
|
|
## 🚀 How It Works
|
|
|
|
### 1. **User Registration**
|
|
- First user becomes administrator automatically
|
|
- Subsequent users become coordinators by default
|
|
- All via your existing Google OAuth flow
|
|
|
|
### 2. **Role Management**
|
|
- **Administrator:** Full access including user management
|
|
- **Coordinator:** Can manage VIPs, drivers, schedules
|
|
- **Driver:** Can view assigned schedules
|
|
|
|
### 3. **User Management Interface**
|
|
- Only administrators can access user management
|
|
- View all users with profile pictures
|
|
- Change roles instantly
|
|
- Delete users (except yourself)
|
|
- Clear role descriptions
|
|
|
|
## 📋 Usage
|
|
|
|
### For Administrators:
|
|
1. Login with Google (first user becomes admin)
|
|
2. Access user management interface
|
|
3. View all registered users
|
|
4. Change user roles as needed
|
|
5. Remove users if necessary
|
|
|
|
### API Examples:
|
|
```bash
|
|
# List all users (admin only)
|
|
curl -H "Authorization: Bearer YOUR_JWT_TOKEN" \
|
|
http://localhost:3000/auth/users
|
|
|
|
# Update user role
|
|
curl -X PATCH \
|
|
-H "Authorization: Bearer YOUR_JWT_TOKEN" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"role": "administrator"}' \
|
|
http://localhost:3000/auth/users/user@example.com/role
|
|
|
|
# Delete user
|
|
curl -X DELETE \
|
|
-H "Authorization: Bearer YOUR_JWT_TOKEN" \
|
|
http://localhost:3000/auth/users/user@example.com
|
|
```
|
|
|
|
## 🔒 Security Features
|
|
|
|
- **Role-based access control** - Only admins can manage users
|
|
- **Self-deletion prevention** - Admins can't delete themselves
|
|
- **JWT token validation** - All endpoints require authentication
|
|
- **Input validation** - Role validation on updates
|
|
|
|
## ✅ Important Notes
|
|
|
|
### **Persistent File Storage**
|
|
- Users are stored in your existing JSON data file
|
|
- **Users are preserved across server restarts**
|
|
- Perfect for development and production
|
|
- Integrates seamlessly with your existing data storage
|
|
|
|
### **Simple & Lightweight**
