## What it is
Depcheck is a CLI tool that analyzes an npm project's dependencies to find unused packages and missing entries in package.. It supports JavaScript, TypeScript, JSX, Vue, SASS, and CoffeeScript syntax, plus specials for tools like Babel and ESLint.

## Use cases
- find unused npm dependencies in my project
- check which packages in package. are never imported
- detect missing dependencies not listed in package.
- clean up devDependencies in a JavaScript project
- audit dependency usage in a TypeScript or Vue project

## When to choose
- you have a legacy JavaScript/TypeScript project and want a quick unused-dependency check
- you need a simple npx-runnable audit without configuration

## When to avoid
- you need active maintenance or support for modern tooling, monorepos, or newer frameworks - the README recommends knip instead
- you need reliable TypeScript or monorepo support
