scss-splinter enables the creation of multiple stylesheets from a common set of modules with minimal effort via SCSS mixins and functions.

scss-splinter accepts an options object that specifies a partial, a base, and a optional keyword to grep for.

  const parse = require('scss-splinter');

  parse({
    partial: 'src/scss/_brands.scss',
    base: 'src/scss/_base.scss',
    keyword: 'split',
  })

1. Partial is the name of the file that scss-splinter will generate with "split" code, e.g. code that is specified in the matching mixin or sass-function.

2. Base is the name of the main sass index file in a project. This is the file scss-splinter will use to find all the files it needs to parse.

scss-splinter fills the partial file with "split" scss and returns a promise that contains "global" scss. It's up to the project to determine what to do with this global string. One approach would be to run the string through node-sass and write the compiled css to a file.

  const fs = require('fs');
  const parse = require('scss-splinter');
  const nodeSass = require('node-sass');

  parse({
    partial: 'src/scss/_brands.scss',
    base: 'src/scss/_base.scss',
    keyword: 'split',
  })
  .then((scss) => {
    const compiledGlobal = nodeSass.renderSync({
      data: scss,
    });

    fs.writeFileSync('global.css', compiledGlobal.css.toString());
  });

If your SCSS files are not located at src/scss, you can pass cwd in the params:

  const parse = require('scss-splinter');

  parse({
    partial: '_brands.scss',
    base: '_base.scss',
    keyword: 'split',
    cwd: 'i/keep/my/scss/files/here',
  })
