Usage

Any CSS, JS, JSON, HTML, SVG or XML resource can be minified using resources.Minify which takes for argument the resource object.

{{ $css := resources.Get "css/main.css" }}
{{ $style := $css | resources.Minify }}

Note that you can also minify the final HTML output to /public by running hugo --minify.
