Dependency Checker

What is Dependency Checking?

Dependency checking analyzes package dependencies in your project to identify outdated packages, version conflicts, and security vulnerabilities. It compares installed package versions with the latest versions available in package registries. Regular dependency checking helps maintain project security and compatibility.

Our free Dependency Checker analyzes your package.json file and checks dependencies against the npm registry. It identifies outdated packages and shows current vs. latest versions. For comprehensive analysis, use npm outdated or specialized dependency management tools.

Why Check Dependencies?

Dependency checking is important for:

• Identifying outdated packages
• Finding security vulnerabilities
• Detecting version conflicts
• Maintaining project compatibility
• Planning updates

Best Practices

• Regular Checks: Check dependencies regularly
• Update Carefully: Test updates before applying
• Use Lock Files: Commit package-lock.json
• Security Audits: Run npm audit for security
• Version Pinning: Pin critical dependency versions
