Amazon CodeWhisperer 치트 시트

개요

Amazon CodeWhisperer는 실시간으로 지능적인 코드 제안을 제공하는 AWS의 AI 기반 코드 완성 서비스입니다. 코드와 주석을 분석하여 문맥에 맞는 관련 추천을 생성하며, 여러 프로그래밍 언어를 지원하고 인기 있는 IDE와 통합됩니다.

⚠️ 참고: CodeWhisperer는 Amazon Q Developer로 리브랜딩되었습니다. 이 치트 시트는 레거시 CodeWhisperer 인터페이스와 명령어를 다룹니다.

보안 스캔

취약점 탐지

# Automatic security scanning
# Detects common vulnerabilities:
# - SQL injection
# - Cross-site scripting (XSS)
# - Hardcoded credentials
# - Insecure cryptographic practices
# - Path traversal vulnerabilities

수동 보안 스캔

# VS Code:
# 1. Open Command Palette (Ctrl+Shift+P)
# 2. Type "CodeWhisperer Security Scan"
# 3. Select files to scan
# 4. Review results in Problems panel

# JetBrains:
# 1. Tools > AWS > CodeWhisperer > Security Scan
# 2. Select scope (file/project)
# 3. Review results in inspection panel

보안 스캔 결과

# High severity issues:
# - Critical security vulnerabilities
# - Immediate attention required
# - Detailed remediation steps provided

# Medium/Low severity:
# - Potential security concerns
# - Best practice recommendations
# - Code quality improvements

명령줄 사용

Authenticate with AWS Builder ID

codewhisperer auth login

Use AWS credentials

codewhisperer auth login —profile your-aws-profile

Check authentication status

codewhisperer auth status

```bash
# Generate code from prompt
codewhisperer generate --prompt "Python function to sort dictionary by values"

# Generate with context file
codewhisperer generate --prompt "Add error handling" --context main.py

# Interactive mode
codewhisperer interactive
```## 모범 사례
```python
# Good: Specific and descriptive comments
# Function to validate email format using regex and return boolean
def validate_email(email):
    # CodeWhisperer generates accurate implementation

# Bad: Vague comments
# Email function
def email_func():
    # Less accurate suggestions
```### 효과적인 프롬프팅

Troubleshooting

Common Issues

# CodeWhisperer not working:
# 1. Check internet connection
# 2. Verify authentication status
# 3. Restart IDE
# 4. Update AWS Toolkit extension

# No suggestions appearing:
# 1. Check if CodeWhisperer is enabled
# 2. Verify file type is supported
# 3. Check automatic trigger settings
# 4. Try manual trigger (Alt+C)

Performance Issues

# Slow suggestions:
# 1. Close unnecessary files
# 2. Reduce project size
# 3. Check network connectivity
# 4. Update to latest extension version

# High CPU usage:
# 1. Adjust suggestion frequency
# 2. Disable automatic triggers
# 3. Use manual triggers only
# 4. Configure suggestion limits

Debug Information

# VS Code debug info:
# 1. View > Output
# 2. Select "AWS Toolkit" from dropdown
# 3. Check for error messages

# JetBrains debug info:
# 1. Help > Show Log in Explorer
# 2. Look for AWS-related log files
# 3. Check for error patterns

Code Examples

Python Data Processing

# Function to process CSV file and calculate statistics
import pandas as pd
import numpy as np

def process_sales_data(file_path):
    df = pd.read_csv(file_path)
    
    # Calculate key metrics
    total_sales = df['amount'].sum()
    avg_sale = df['amount'].mean()
    top_products = df.groupby('product')['amount'].sum().sort_values(ascending=False).head(5)
    
    return {
        'total_sales': total_sales,
        'average_sale': avg_sale,
        'top_products': top_products.to_dict()
    }

JavaScript API Integration

// Function to fetch user data with error handling and retry logic
async function fetchUserData(userId, maxRetries = 3) {
    for (let attempt = 1; attempt <= maxRetries; attempt++) {
        try {
            const response = await fetch(`/api/users/${userId}`);
            
            if (!response.ok) {
                throw new Error(`HTTP error! status: ${response.status}`);
            }
            
            const userData = await response.json();
            return userData;
            
        } catch (error) {
            console.error(`Attempt ${attempt} failed:`, error.message);
            
            if (attempt === maxRetries) {
                throw new Error(`Failed to fetch user data after ${maxRetries} attempts`);
            }
            
            // Wait before retry
            await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
        }
    }
}

Java Spring Boot Controller

// REST controller for product management with validation
@RestController
@RequestMapping("/api/products")
@Validated
public class ProductController {
    
    @Autowired
    private ProductService productService;
    
    @PostMapping
    public ResponseEntity<Product> createProduct(@Valid @RequestBody ProductDTO productDTO) {
        try {
            Product product = productService.createProduct(productDTO);
            return ResponseEntity.status(HttpStatus.CREATED).body(product);
        } catch (ValidationException e) {
            return ResponseEntity.badRequest().build();
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
        }
    }
}
