Can you add console.log to css-loader sources to see that CSS does it received?

Seems like postcss-simple-vars didn’t transform CSS. Maybe PostCSS doesn’t see the config with the plugins list.

@senya-g Did you mean to write without quotes?

$prefix: foo;

Your version would output .'foo'-button {}, whereas I expect you want .foo-button {}
