WORK IN PROGRESS...

This Node module is an attempt to provide a faster binding to Ruby Sass than currently available.

Explanation: Sass in a Rails app with LiveReload seems much faster than things like gulp-ruby-sass. I'm guessing this is because Rails runs Sass using the same Ruby process every compile, avoiding Ruby spin-up time, and benefiting from in-memory caching. This module tries to do something similar. Benchmarks to follow.

Installation

$ npm install ruby-sass

Usage

var sass = require('ruby-sass');
 
sass('path/to/something.scss', function (err, css) {
    // got the css (or an error with a *sass* stack trace) 
});

Repeated calls should be faster than the first one.

You can also pass options as a second argument.

Options

• loadPaths (array)
• sourcemap (boolean)

Alternative API

var Sass = require('ruby-sass').Sass;
 
var sass = new Sass();
 
sass.compile(filename, options, callback); // same as the `sass` function in standard API. 

Constructor options

These are optional.

• port – which port to use
• basePort (default: 8500) – if you don't set a port, portfinder will be used to find one manually, starting at this base port.

To do

• source maps
• make it so you don't have to wait for ready
• kill ruby process when node exits or on uncaught exception
• make a way to stop it manually
• write benchmarks
• see if repeat runs on the same file are actually any faster. if not, look at using Sass::Plugin (?)
• make post install script to check if required gems are installed and print instructions to install them (or just install them?)
• pass in sass options per-file, not per-instance
• simplify api
• test it on windows
