• Identifying refactoring candidates
• Technical debt monitoring
• Code review automation
• CI/CD quality gates
• Team performance tracking
• Legacy code analysis

Quick Start

Minimal working example:

import * as ts from "typescript";
import * as fs from "fs";

interface ComplexityMetrics {
  cyclomaticComplexity: number;
  cognitiveComplexity: number;
  linesOfCode: number;
  functionCount: number;
  classCount: number;
  maxNestingDepth: number;
}

class CodeMetricsAnalyzer {
  analyzeFile(filePath: string): ComplexityMetrics {
    const sourceCode = fs.readFileSync(filePath, "utf-8");
    const sourceFile = ts.createSourceFile(
      filePath,
      sourceCode,
      ts.ScriptTarget.Latest,
      true,
    );
