   - 401/403 responses auto-logout and redirect

4. **Role-Based Access Control:**

---

## Technical Details

### Database Migrations Applied:
- Created `users` table
- Seeded default superadmin user
- Existing schema already had campaign_id foreign key on posts

### NPM Packages Installed:
- `bcrypt` - Password hashing
- `jsonwebtoken` - JWT token generation and verification

### Authentication Flow:
1. User logs in with email/password
2. Server validates credentials and generates JWT token
3. Token stored in localStorage
4. All API requests include `Authorization: Bearer <token>` header
5. Server validates token on protected routes
6. Invalid/expired tokens trigger logout and redirect to login

### Security Measures:
- Passwords hashed with bcrypt (10 rounds)
- JWT tokens expire after 7 days
- Protected routes require valid authentication
- Role-based access control enforced
- Cannot delete own user account
- Proper error handling and user feedback

---

## Testing

### Server:
✅ Server starts successfully on port 3001
✅ Default superadmin created
✅ Uploads directory created and served

### Client:
✅ Build completes successfully
✅ All components compile without errors

### Default Credentials:
- **Email:** f.mahidi@samayainvest.com
- **Password:** admin123

**⚠️ IMPORTANT:** Change the default password immediately after first login!

## Next Steps (Recommended)

1. **Change Default Password:** Login and change the default superadmin password
2. **Add More Users:** Create user accounts for your team members
3. **Test Role Permissions:** Verify that Manager and Contributor roles have appropriate access
4. **Customize Avatars:** Add avatar images for users
5. **Password Reset:** Consider adding password reset functionality
6. **Session Management:** Consider adding "Remember Me" functionality
7. **Activity Logging:** Add user activity logs for audit trail
