This is a Go API backed by the native [Dart Sass Embedded](https://github.com/sass/dart-sass-embedded) executable.
The primary motivation for this project is to provide `SCSS` support to [Hugo](https://gohugo.io/). I welcome PRs with bug fixes. I will also consider adding functionality, but please raise an issue discussing it first.
For LibSass bindings in Go, see [GoLibSass](https://github.com/bep/golibsass).
The benchmark below compares [GoLibSass](https://github.com/bep/golibsass) with this library. This is almost twice as fast when running single-threaded, but slower when running with multiple Goroutines. We're communicating with the compiler process via stdin/stdout, which becomes the serialized bottle neck here. That may be possible to improve, but for most practical applications (including Hugo), this should not matter.
