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.
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
