get-sass-vars-sync

Get Sass variables synchronously as JSON object.

Install

npm install get-sass-vars-sync node-sass --save-dev

The sass-loader requires node-sass as peerDependency. Thus you are able to specify the required versions accurately.

Usage

const fs = require('fs');
const sassVarsSync = require('get-sass-vars-sync').default;

sassVarsSync(fs.readFileSync('./index.scss', 'utf-8'))
    .then(function ( json ) {
        console.log(json);
        /* {
        "$foo": "16px",
        "$bar": "17.6px",
        "$baz": 42,
        "$foo-bar": "#666",
        "$foo-bar-baz": "#262626",
        "$foo-bar-baz-bad": "#123",
        "$grault": [1, 2, "3", "4px", "42%", "1.23457px", [4, 5, 6], {"foo": "bar baz"}],
        "$garply": {"foo": 1, "bar": [2, 3], "baz": "3 3 3"},
        "$qux": false,
        "$fred": true,
        "$corgle": null
        } */
  });
