This is a Ruby library that implements the host side of the Embedded Sass protocol.

It exposes a Ruby API for Sass that's backed by a native Dart Sass executable on supported hardware architectures and platforms or a Node.js Dart Sass executable everywhere else.

gem install sass-embedded

The Ruby API provides two entrypoints for compiling Sass to CSS.

• Sass.compile takes a path to a Sass file and return the result of compiling that file to CSS.

require 'sass-embedded'
result = Sass.compile('style.scss')
puts result.css
compressed = Sass.compile('style.scss', style: :compressed)
puts compressed.css

• Sass.compile_string takes a string that represents the contents of a Sass file and return the result of compiling that file to CSS.

require 'sass-embedded'
result = Sass.compile_string('h1 { font-size: 40px; }')
puts result.css
compressed = Sass.compile_string('h1 { font-size: 40px; }', style: :compressed)
puts compressed.css
