npm install --save-dev sass-to-js-var-loader
This simple, stupid loader will find all variables in a SASS file and provide their compiled values in a JS object with the camel-cased variable names as the keys. This can be useful when you need to reference styling information within your JS files (hopefully a fairly rare occurance).
test.scss
$foo: #f00;
$bar-baz: lighten(#444, 20%);
test.js
var variables = require('sass-to-js-var!./test.scss');
console.log(variables.foo);
console.log(variables.barBaz);
Output
#f00
