🛤️ Project Root Path Normalization System

Consistent caching and path handling regardless of execution location:

• 📁 Auto Project Root Detection: Automatically finds project root using markers (package.json, .git, tsconfig.json, etc.)
• 🔄 Path Normalization: Converts any path to project-root-relative format (./src/file.ts)
• 💾 Cache Efficiency: Single cache entry per file regardless of execution directory
• 🌍 Cross-Platform: Unified path handling for Windows/Unix systems
• ⚡ Performance Optimized: Cached project root detection for repeated operations

// All paths normalized to project root - same cache key
await analyzer.analyzeFile('./src/component.tsx');           // From project root
await analyzer.analyzeFile('src/component.tsx');             // From project root
await analyzer.analyzeFile('/full/path/src/component.tsx');  // Absolute path
await analyzer.analyzeFile('../project/src/component.tsx');  // From subdirectory

// All generate the same normalized path: "./src/component.tsx"

    console.log(format(tomorrow, 'yyyy-MM-dd'));
  }, [date]);

  const debouncedUpdate = debounce(() => {
    setDate(new Date());
  }, 1000);

  // throttle is imported but never used

  return <div onClick={debouncedUpdate}>Click me</div>;
}
`;

  const parser = new TypeScriptParser();
  const parseResult = await parser.parse('/example.tsx', code);

  const extractor = new EnhancedDependencyExtractor();
  const result = extractor.extractEnhanced(parseResult.ast, '/example.tsx');

🎯 Usage Scenarios

1. Code Review and Optimization

• Identify unused imports for code cleanup
• Find over-imported packages for tree-shaking
• Analyze method usage patterns for refactoring

2. Bundle Size Optimization

• Detect inefficient lodash/utility library usage
• Recommend specific imports over namespace imports
• Calculate potential bundle size savings

3. Dependency Management

• Monitor actual usage vs. declared dependencies
• Identify packages with low utilization rates
• Track method-level dependency patterns

4. Development Workflow

• Automated dead code detection in CI/CD
• Usage-based dependency recommendations
• Performance-focused import analysis

💡 Best Practices

• Use for Large Codebases: Most effective on projects with many dependencies
• Regular Analysis: Run periodically to maintain clean imports
• Combine with Linting: Integrate findings with ESLint unused import rules
• Focus on Heavy Packages: Prioritize analysis of large libraries (lodash, moment, etc.)
• Bundle Analysis: Use results to guide tree-shaking and bundler configuration

// 2. Export 유형별 필터링
const publicAPI = exportData.exportMethods.filter(exp =>
  exp.exportType === 'function' ||
  (exp.exportType === 'class_method' && exp.visibility === 'public')
);

// 3. 클래스 구조 분석

    memoryLimit: 200 * 1024 * 1024 // Increase to 200MB
  });
  

• Timeout Issues

  extractor.configure({
    timeout: 30000 // Increase to 30 seconds
  });
  

• Parser Errors

  const parseResult = await parser.parse(filePath, sourceCode);

Performance Tips

• Use appropriate memory limits for your use case
• Set reasonable timeouts for large files
• Consider processing files in batches for bulk analysis
• Cache parser instances for repeated use

The EnhancedExportExtractor is production-ready with comprehensive testing and provides detailed insights for code analysis, documentation generation, API discovery, and export management workflows.

Simple Function API

const {
  analyzeTypeScriptFile,
  extractDependencies,
  getBatchAnalysis,
  analyzeDirectory
} = require('@context-action/dependency-linker');

// Standard analysis
const result = await analyzeTypeScriptFile('./src/index.ts', {
  format: 'json',
  includeSources: true,
  parseTimeout: 10000
});

// Enhanced integrated analysis (recommended)
const integratedResult = await analyzeTypeScriptFile('./src/index.ts', {
  useIntegrated: true,
  preset: 'balanced',
  format: 'report'
});

// Custom integrated configuration
const customResult = await analyzeTypeScriptFile('./src/index.ts', {
  useIntegrated: true,
  detailLevel: 'comprehensive',
  optimizationMode: 'accuracy',
  enabledViews: ['summary', 'table', 'tree'],
  maxStringLength: 2000
});

// Batch processing with presets
const results = await getBatchAnalysis([
  './src/index.ts',
  './src/utils.ts'
], {
  concurrency: 3,
  useIntegrated: true,
  preset: 'fast',
  onProgress: (completed, total) => console.log(`${completed}/${total}`)
});

// Directory analysis with configuration
const dirResults = await analyzeDirectory('./src', {
  extensions: ['.ts', '.tsx'],
  ignorePatterns: ['**/*.test.ts', '**/node_modules/**'],
  useIntegrated: true,
  preset: 'balanced'
});

Class-based API

const { TypeScriptAnalyzer } = require('@context-action/dependency-linker');

// Create analyzer with options
const analyzer = new TypeScriptAnalyzer({
  enableCache: true,
  cacheSize: 1000,
  defaultTimeout: 30000
});

// Analyze file with options
const result = await analyzer.analyzeFile('./src/index.ts', {
  format: 'json',
  includeSources: true
});

// Convenience methods
const dependencies = await analyzer.extractDependencies('./src/index.ts');
const imports = await analyzer.getImports('./src/index.ts');
const exports = await analyzer.getExports('./src/index.ts');

// Batch processing
const batchResult = await analyzer.analyzeFiles([
  './src/index.ts',
  './src/utils.ts'
], {
  concurrency: 5,
  continueOnError: true
});

// Clean up
analyzer.clearCache();

🗄️ 캐시 관리

const { TypeScriptAnalyzer, resetFactoryAnalyzers, resetSharedAnalyzer } = require('@context-action/dependency-linker');

const analyzer = new TypeScriptAnalyzer();

// 개별 분석기 캐시 초기화
analyzer.clearCache();

// 팩토리 공유 분석기 초기화 (권장: 테스트 환경)
resetFactoryAnalyzers();
resetSharedAnalyzer();

// 캐시 통계 확인
const stats = analyzer.getCacheStats();
console.log(`Cache size: ${stats.size}, hits: ${stats.hits}`);

Advanced Batch Processing

const { BatchAnalyzer } = require('@context-action/dependency-linker/dist/api/BatchAnalyzer');

const batchAnalyzer = new BatchAnalyzer(analyzer, {
  maxConcurrency: 5,
  enableResourceMonitoring: true,
  memoryLimit: 512 // MB
});

const result = await batchAnalyzer.processBatch(filePaths, {
  continueOnError: true,
  onProgress: (completed, total) => {
    console.log(`Progress: ${completed}/${total}`);
  },
  onFileError: (filePath, error) => {
    console.log(`Error in ${filePath}: ${error.message}`);
  }
});

console.log('Resource metrics:', batchAnalyzer.getResourceMetrics());
batchAnalyzer.dispose();
