> [gulp](http://gulpjs.com/) plugin to minify CSS, using [clean-css](https://github.com/jakubpawlowicz/clean-css)

## Regarding Issues

This is just a simple [gulp](https://github.com/gulpjs/gulp) plugin, which means it's nothing more than a thin wrapper around `clean-css`. If it looks like you are having CSS related issues, please contact [clean-css](https://github.com/jakubpawlowicz/clean-css/issues). Only create a new issue if it looks like you're having a problem with the plugin itself.

## Install

```
npm install gulp-clean-css --save-dev
```

## API

### cleanCSS([*options*], [*callback*])

#### options

See the [`CleanCSS` options](https://github.com/jakubpawlowicz/clean-css#how-to-use-clean-css-api).

```javascript
let gulp = require('gulp');
let cleanCSS = require('gulp-clean-css');

gulp.task('minify-css', () => {
  return gulp.src('styles/*.css')
    .pipe(cleanCSS({compatibility: 'ie8'}))
    .pipe(gulp.dest('dist'));
});
```

#### callback

Useful for returning details from the underlying [`minify()`](https://github.com/jakubpawlowicz/clean-css#using-api) call. An example use case could include logging `stats` of the minified file. In addition to the default object, `gulp-clean-css` provides the file `name` and `path` for further analysis.

```javascript
let gulp = require('gulp');
let cleanCSS = require('gulp-clean-css');

gulp.task('minify-css', () => {
  return gulp.src('styles/*.css')
    .pipe(cleanCSS({debug: true}, (details) => {
      console.log(`${details.name}: ${details.stats.originalSize}`);
      console.log(`${details.name}: ${details.stats.minifiedSize}`);
    }))
  .pipe(gulp.dest('dist'));
});
```

[Source Maps](http://www.html5rocks.com/tutorials/developertools/sourcemaps/) can be generated by using [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps).

```javascript

let gulp = require('gulp');
let cleanCSS = require('gulp-clean-css');
let sourcemaps = require('gulp-sourcemaps');

gulp.task('minify-css',() => {
  return gulp.src('./src/*.css')
    .pipe(sourcemaps.init())
    .pipe(cleanCSS())
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));
});
```
