# pkg-config [![version][npm-version]][npm-url] [![License][npm-license]][license-url]

> parse the closest `package.json` and get package specific configurations

Useful for package developers to store package-related configuration in dependent's `package.json`.

defaults to `config` as root, which allows you to still leverage npm's standard [config](https://docs.npmjs.com/files/package.json#config)
