# Check for vulnerabilities
npm audit --audit-level=moderate

# Analyze bundle size impact
npx bundle-phobia-cli package-name

Core Functionality

Key Features

1. Dependency Audit: Security vulnerabilities and outdated packages
2. Bundle Analysis: Size impact and tree-shaking effectiveness
3. Circular Detection: Find and resolve circular dependencies
4. License Compliance: Verify license compatibility
5. Update Strategy: Safe update recommendations

Usage Examples

Example 1: Full Dependency Audit

import { DependencyAnalyzer } from '@j0kz/dependency-analyzer';

const analyzer = new DependencyAnalyzer();
const report = await analyzer.audit({
  checkVulnerabilities: true,
  checkOutdated: true,
  checkLicenses: true,
  checkBundleSize: true
});

console.log(report.summary);

Example 2: Find Circular Dependencies

const circles = await analyzer.findCircularDependencies();
if (circles.length > 0) {
  console.log('Circular dependencies found:', circles);
}

Configuration

{
  "dependency-analyzer": {
    "autoFix": false,
    "severity": "moderate",
    "ignoreDev": false,
    "maxBundleSize": "500kb",
    "allowedLicenses": ["MIT", "Apache-2.0", "BSD-3-Clause"]
  }
}

Integration with CI/CD

# GitHub Actions example

  run: |
    npm audit --audit-level=moderate
    npx @j0kz/dependency-analyzer audit --fail-on-high

Notes

• Integrates with npm, yarn, and pnpm
• Caches results for faster subsequent runs
• Supports monorepo structures
• Can generate SBOM (Software Bill of Materials)
