# Compress Commons
Compress Commons is a library that defines a common interface for working with archive formats within node.
[![NPM](https://nodei.co/npm/compress-commons.png)](https://nodei.co/npm/compress-commons/)
## Install
```bash
npm install compress-commons --save
```
You can also use `npm install https://github.com/archiverjs/node-compress-commons/archive/master.tar.gz` to test upcoming versions.
## Things of Interest

- [Contributing](https://github.com/archiverjs/node-compress-commons/blob/master/CONTRIBUTING.md)
- [MIT License](https://github.com/archiverjs/node-compress-commons/blob/master/LICENSE-MIT)
## Credits
Concept inspired by [Apache Commons Compress](http://commons.apache.org/proper/commons-compress/)&trade;.
Some logic derived from [Apache Commons Compress](http://commons.apache.org/proper/commons-compress/)&trade; and [OpenJDK 7](http://openjdk.java.net/).
