postcss-modules-dead-css v0.2.3
potscs-modules-dead-css 
A PostCSS plugin to remove unused CSS from CSS Modules. Provide a list of used class names and all unused rule sets will be removed. Most useful in combination with Webpack, where static analysis can figure out the used classes for you.
Usage
var postcss = require("postcss");
var deadcss = require("postcss-modules-dead-css");
var pipeline = postcss([ deadcss({ used: ['class'] }) ]);
pipeline.process(".class { color:blue; } .otherClass { color:red; } .class:hover { color:green; }").toString();
// => '.class { color:blue; } .class:hover { color:green; }'Options
| Name | Default | Description |
|---|---|---|
used | [] | Array of class names to keep (don't include preceding '.') |
ignore | [] | Array of selectors to keep (strings or RegExps) |
allowIds | false | Allow selectors which contain ids, eg #id.usedClass |
allowNonClassCombinators | false | Allow selectors with subselectors that don't match a used class, eg .usedClass > a |
allowNonClassSelectors | false | Allow selectors that don't contain a used class at all, eg div + span |
The allow* options should not be necessary with CSS Modules but may be useful when importing legacy CSS as if it were modular.
Thanks
A large part of the filtering code is lifted from uncss. Thanks!
