Install
$ npm install cssnext-brunch
Usage
Add a cssnext section in the plugins section of your brunch config file
plugins: cssnext: sourcemap: true features: prefixes: browsers:'> 5%''last 3 version''IE 8' import: path: 'app/css'Options are directly passed to cssnext, so checkout cssnext options directly.
Notes
cssnext-brunch is a compile-type plugin, so it's play well optimizer like clean-css-brunch
SourceMaps
For now, sourcemap is inlined in the generated css. If you want to enable cssnext sourcemap, you should disabled brunch default sourcemap.
Also, it seems that minification (via compress option or via another brunch plugin) broke sourcemap support.
Import
By default, brunch concatenates css files. In order to take advantage of postcss-import, you'll need to add _ to filename (* @import "_filename.css"*.
You also need to specify import folder in the brunch config.
import: "app/css" for example.
Production
When build for production, inlined sourcemap is disabled.
