# Comprehensive Project Review and Fix Plan

## 1. Missing Frontend Components

### Issue
The admin layout has navigation links for several pages, but the corresponding Vue components are missing:
- `/admin/posts` - Posts.vue
- `/admin/works` - Works.vue  
- `/admin/snippets` - Snippets.vue
- `/admin/settings` - Settings.vue
- `/admin/logs` - Logs.vue

### Fix
Create the missing admin page components with basic CRUD functionality:
- Posts.vue - Display and manage blog posts
- Works.vue - Display and manage portfolio works
- Snippets.vue - Display and manage code snippets
- Settings.vue - Manage system configurations
- Logs.vue - View operation logs

## 2. Backend Security Issues

### Issue 1: Hardcoded JWT Secret
- **Location**: `server/middleware/auth.go:14`
- **Impact**: Compromises all JWT tokens if source code is exposed

### Fix
Replace hardcoded secret with environment variable:
```go
var jwtSecret = []byte(os.Getenv("JWT_SECRET"))
```

### Issue 2: Hardcoded Password Check
- **Location**: `server/main.go:37`
- **Impact**: All admin accounts use the same password "admin123"

### Fix
Implement proper bcrypt password hashing and verification:
```go
// Replace with actual bcrypt comparison
if err := bcrypt.CompareHashAndPassword([]byte(user.PasswordHash), []byte(req.Password)); err != nil {
    c.JSON(http.StatusUnauthorized, gin.H{"error": "Invalid username or password"})
    return
}
```

### Issue 3: Missing Role-Based Authorization
- **Location**: `server/main.go` - admin routes
- **Impact**: No role-based access control for admin endpoints

### Fix
Implement role middleware for admin routes:
```go
// Example: Only allow admin users to delete users
authAdmin.DELETE("/users/:id", middleware.RoleMiddleware("admin"), adminDeleteUser)
```

### Issue 4: Insecure CORS Configuration
- **Location**: `server/main.go:564`
- **Impact**: Allows all origins (*) which is insecure for production

### Fix
Restrict CORS to specific origins in production:
```go
c.Writer.Header().Set("Access-Control-Allow-Origin", os.Getenv("ALLOWED_ORIGINS"))
```

### Issue 5: Missing CSRF Protection
- **Location**: All POST/PUT/DELETE endpoints
- **Impact**: Vulnerable to CSRF attacks

### Fix
Implement CSRF protection middleware

### Issue 6: Missing Rate Limiting
- **Location**: Authentication endpoints
- **Impact**: Vulnerable to brute force attacks

### Fix
Implement rate limiting middleware for login endpoint

## 3. Database Issues

### Issue 1: Inconsistent Role Implementation
- **Location**: Database schema
- **Impact**: User table uses ENUM for role instead of foreign key to roles table

### Fix
1. Modify user table to use role_id foreign key instead of role enum
2. Update user registration and authentication logic

### Issue 2: Missing API Endpoints
- **Location**: `server/main.go`
- **Impact**: No endpoints for tags and access logs

### Fix
Implement missing API endpoints:
- Tag management endpoints
- Access log viewing endpoints

## 4. Implementation Issues

### Issue 1: Inconsistent ID Types
- **Location**: Multiple models and endpoints
- **Impact**: Confusion and potential bugs in data handling

### Fix
Standardize ID types across the application:
- Use uint for auto-incrementing primary keys
- Use string for UUIDs if needed

### Issue 2: Missing Validation
- **Location**: Many API endpoints
- **Impact**: Potential for invalid data in database

### Fix
Implement validation middleware for all request bodies

### Issue 3: Incomplete Error Handling
- **Location**: Several repository functions
- **Impact**: Unhandled errors could crash the server

### Fix
Add proper error handling and logging throughout the codebase

## 5. Code Quality Improvements

### Issue 1: Duplicate Code
- **Location**: Similar CRUD operations across endpoints
- **Impact**: Increased maintenance effort

### Fix
Refactor common functionality into reusable functions/middleware

### Issue 2: Missing Documentation
- **Location**: Most files
- **Impact**: Difficult for new developers to understand the codebase

### Fix
Add appropriate comments and documentation

## Implementation Order

1. **Create missing frontend components** - Priority 1
2. **Fix critical security issues** - Priority 1
3. **Implement role-based access control** - Priority 2
4. **Fix database inconsistencies** - Priority 2
5. **Implement missing API endpoints** - Priority 3
6. **Improve code quality and documentation** - Priority 3

This plan addresses all identified issues while prioritizing critical functionality and security fixes first.
