leodidopostcss-clean 
PostCss plugin to minify your CSS
Compression will be handled by clean-css, which according to this benchmark is one of the top (probably the best) libraries for minifying CSS.
Install
With npm do:
npm install postcss-clean --saveExample
Input
.try {
color: #607d8b;
width: 32px;
}Output
.try{color:#607d8b;width:32px}Input
:host {
display: block;
}
:host ::content {
& > * {
color: var(--primary-color);
}
}Output
:host{display:block}:host ::content>*{color:var(--my-color)}Note this example assumes you combined postcss-clean with other plugins (e.g. postcss-nesting).
API
clean([options])
Note that postcss-clean is an asynchronous processor. It cannot be used like this:
var out = postcss([ clean() ]).process(css).css;
console.log(out)Instead make sure your runner uses the async APIs:
postcss([ clean() ]).process(css).then(function(out) {
console.log(out.css);
});options
It simply proxies the clean-css options. See the complete list of options here.
Usage
See the PostCSS documentation for examples for your environment.
