Mayu::CSS

This library is used for CSS parsing/transformations/minifications in Mayu Live.

It uses lightningcss (webpage) which is a state-of-the-art CSS parser/transformer/bundler/minifier.

I do not know Rust. I have no idea what I'm doing.

Mayu::CSS is published on rubygems.org and there are pre-built extensions for:

• aarch64-linux
• arm64-darwin
• x86_64-darwin
• x86_64-linux

gem install mayu-css

require "mayu/css"

result = Mayu::CSS.transform("/app/components/Hello.css", <<~CSS)
  ul { background: rgb(0 128 255 / 50%); }
  li { border: 1px solid #f0f; }
  .foo { border: 1px solid #f0f; }
  .bar { background: url("./bar.png"); }
