# optimize-cssnano-plugin [![Build Status](https://travis-ci.org/intervolga/optimize-cssnano-plugin.svg?branch=master)](https://travis-ci.org/intervolga/optimize-cssnano-plugin)

It will search for CSS assets during the Webpack build and minimize it with [cssnano](http://github.com/ben-eb/cssnano).
Solves [extract-text-webpack-plugin](http://github.com/webpack/extract-text-webpack-plugin) CSS duplication problem.

Just like [optimize-css-assets-webpack-plugin](http://github.com/NMFR/optimize-css-assets-webpack-plugin) but more accurate with source maps.

## Installation:

Using npm:
```shell
$ npm install --save-dev @intervolga/optimize-cssnano-plugin
```
