- Lightning fast Sass compiling with libsass, Node-sass and Grunt-sass — by Ben Frain, August 2013
- Node, Express and libSass — Node, Express and libSass: a project from scratch workshop
LibSass is an implementation of Sass in C/C++, designed to be easy to integrate into many different languages. However, as time wore on it ended up lagging behind Dart Sass in features and CSS compatibility. LibSass is now deprecated—new projects should use Dart Sass instead.
LibSass is just a library. To run the code locally (i.e. to compile your stylesheets), you need an implementer, or "wrapper". There are a number of other wrappers for LibSass. We encourage you to write your own wrapper — the whole point of LibSass is that we want to bring Sass to many other languages, not just Ruby!
Below are the LibSass wrappers that we're currently aware of. Sometimes there are multiple wrappers per language – in those cases, we put the most recently-updated wrapper first.
SassC (get it?) is a wrapper written in C.
To run the compiler on your local machine, you need to build SassC. To build SassC, you must have either a local copy of the LibSass source or it must be installed into your system. For development, please use the source version. You must then setup an environment variable pointing to the LibSass folder, for example:
The executable will be in the bin folder. To run it, try something like:
./bin/sassc [input file] > output.css
The Lua wrapper is found at lua-sass.
LibSass has also been ported back into Ruby for the sassc-ruby project.
sass_rscrate is a LibSass wrapper and is updated regularly.
The only Scala project, Sass-Scala, hasn't been updated in a couple of years.
