## What it is
npm-check is a Node.js CLI tool that checks npm projects for outdated, incorrect, and unused dependencies. It offers an interactive update mode and works with global packages, scoped packages, and private registries.

## Use cases
- find outdated npm dependencies in a project
- detect unused dependencies in package.json
- interactively update npm packages
- audit global npm packages for updates
- check dependency versions in CI

## When to choose
- you maintain an npm-based JavaScript project and want a friendly dependency audit
- you want interactive updating with links to package docs
- you need a non-zero exit code for CI dependency checks

## When to avoid
- you use Yarn or pnpm lockfiles exclusively and prefer their native tooling
- you need automated security vulnerability scanning rather than staleness checks

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: cli, developer-tools, dependency-audit, package-manager
- domain: developer-tools, version-control
- platform: cli, cross-platform
