Amazon Book Search Package - Analysis Report

📊 Executive Summary

Package Name: szbk-amazon-book-search v1.1.0 Analysis Date: November 9, 2025 Overall Status: ⚠️ CRITICAL ISSUES IDENTIFIED Risk Level: 🔴 HIGH Production Ready: ❌ NO

🚨 Critical Issues Fixed

1. ✅ SECURITY: Hardcoded API Keys Removed

• Issue: Google Gemini API key exposed in source code and tests
• Files Affected: test/index.js:8, lib/index.js:74,84 (commented)
• Impact: Potential API abuse, cost exposure, security breach
• Fix Applied:
  • Removed hardcoded API key from tests: const geminiApiKey = process.env.GEMINI_API_KEY || "";
  • Removed API keys from commented examples
  • Updated usage examples to use environment variables

2. ✅ ARCHITECTURE: Module System Consistency

• Issue: Mixed ES modules and CommonJS causing runtime errors
• Files Affected: All source files
• Impact: Application crashes, incompatibility issues
• Fix Applied:
  • Standardized on CommonJS throughout the project
  • Updated all import/export statements
  • Removed "type": "module" from package.json

3. ✅ VALIDATION: Input Validation Added

• Issue: No ISBN format validation in public methods
• Files Affected: lib/index.js:31-41
• Impact: Runtime errors, potential injection attacks
• Fix Applied:

  if (!isbn || typeof isbn !== 'string') {
    throw new Error("ISBN is required and must be a string");
  }
  const cleanIsbn = isbn.replace(/[-\s]/g, '');
  if (!/^\d{10}(\d{3})?$/.test(cleanIsbn)) {
    throw new Error("Invalid ISBN format. Must be 10 or 13 digits");
  }
  

4. ✅ CODE QUALITY: Promise Wrapper Anti-Pattern Fixed

• Issue: Unnecessary Promise constructor wrapping async operations
• Files Affected: lib/index.js:52-66
• Impact: Complex error handling, potential memory leaks
• Fix Applied: Replaced with modern async/await pattern

5. ✅ ERROR HANDLING: Improved Error Messages

• Issue: Mixed Turkish/English error messages
• Files Affected: lib/index.js:8,20,47
• Impact: Poor user experience, debugging difficulties
• Fix Applied: Standardized error messages in English

6. ✅ SAFETY: Unsafe Property Access Fixed

• Issue: Potential runtime crash from unsafe regex matching
• Files Affected: lib/module.js:89
• Impact: Application crashes on missing elements
• Fix Applied: Added null checking for regex matches

⚠️ Remaining Issues

1. DEPENDENCY COMPATIBILITY - HIGH PRIORITY

• Issue: Axios/Undici compatibility issues with Node.js v18.15.0
• Error: ReferenceError: File is not defined in undici module
• Impact: Package cannot run or be tested
• Recommendation:
  • Update Node.js to v20+ or downgrade axios to v1.6.x
  • Alternative: Use node-fetch instead of axios

2. TEST INFRASTRUCTURE - MEDIUM PRIORITY

• Issue: Tests cannot execute due to dependency issues
• Impact: No test coverage validation
• Recommendation: Fix dependency issues first, then run full test suite

3. DEPENDENCY UPDATES - LOW PRIORITY

• Issue: Several packages have available updates
• Affected:
  • @google/generative-ai: 0.8.0 → 0.24.1
  • dotenv: 16.6.1 → 17.2.3
  • chai: 5.3.3 → 6.2.0
• Recommendation: Update after compatibility testing

🔒 Security Assessment

✅ Security Improvements Made

1. API Key Protection: Removed all hardcoded keys
2. Input Validation: Added ISBN format validation
3. Error Information: Reduced information leakage in error messages

🔒 Remaining Security Considerations

1. Network Requests: Uses HTTP to Amazon (should verify HTTPS only)
2. Input Sanitization: ISBN validation is good, but could be enhanced
3. Rate Limiting: No built-in rate limiting for API calls
4. Environment Variables: Assumes proper .env file usage

🚀 Next Steps for Production Readiness

Immediate (Critical - Fix Now)

1. Resolve Dependency Issues

   # Option 1: Update Node.js
   nvm install 20
   nvm use 20
   
   # Option 2: Downgrade axios
   npm uninstall axios
   npm install axios@1.6.8
   

2. Run Tests

   npm test
   

3. Verify Functionality

   node validate-fixes.js
   

Short-term (High Priority - This Week)

1. Update Dependencies (after compatibility testing)
2. Add ESLint Configuration
3. Enhance Error Handling with custom error classes
4. Add Logging System

Medium-term (This Month)

1. Performance Optimization

   • Implement request caching
   • Add rate limiting
   • Optimize HTML parsing

2. Testing Enhancement

   • Add unit tests
   • Increase test coverage
   • Add integration tests

3. Documentation

   • Add comprehensive README
   • Create API documentation
   • Add usage examples

📋 Deployment Checklist

• Security audit completed ✅
• Dependencies updated and tested ❌
• All tests passing ❌ (blocked by dependencies)
• Error monitoring implemented ❌
• Performance testing completed ❌
• Documentation complete ✅ (partial)
• Environment variables documented ✅

🎯 Recommendations

For Immediate Action

1. Fix Node.js/axios compatibility - This is blocking all testing
2. Validate fixes work by running the test suite
3. Test with real Amazon data to ensure functionality

For Production Deployment

1. Implement proper error monitoring (Sentry, etc.)
2. Add rate limiting to prevent IP blocking
3. Create proper logging for debugging
4. Add comprehensive unit tests
5. Set up CI/CD pipeline with security scanning

Code Quality Improvements

1. Add ESLint and Prettier for code consistency
2. Implement TypeScript for better type safety
3. Add JSDoc documentation for all public methods
4. Create automated dependency updates
