sass-brunch

Adds Sass support to brunch.

Usage

Install the plugin via npm with npm install --save sass-brunch.

Or, do manual install:

  • Add "sass-brunch": "x.y.z" to package.json of your brunch app. Pick a plugin version that corresponds to your minor (y) brunch version.
  • If you want to use git version of plugin, add "sass-brunch": "git+ssh://git@github.com:brunch/sass-brunch.git".

Options

The default compilation method is libsass, with an automatic revert to the sass ruby gem for .sass files or if compass is @imported. It is possible to set a particular mode regardless of automatic detection. If using a libsass-compatible compass replacement such as compass-mixins, it is necessary to set native mode.

Note that source maps are only supported in the native mode.

config =
  plugins:
    sass:
      mode: 'ruby' # set to 'native' to force libsass

Set additional include paths:

config =
  plugins:
    sass:
      options:
        includePaths: ['node_modules/foundation/scss']

Print line number references as comments or sass's FireSass fake media query:

config =
  plugins:
    sass:
      debug: 'comments' # or set to 'debug' for the FireSass-style output

Set the precision for arithmetic operations. This is useful for building Bootstrap, Zurb Foundation, and the like.

config =
  plugins:
    sass:
      precision: 8

Allow the ruby compiler to write its normal cache files in .sass-cache (disabled by default). This can vastly improve compilation time.

config =
  plugins:
    sass:
      allowCache: true

To enable embedded source maps, pass the option sourceMapEmbed. This is only supported in native mode; Ruby Sass isn't supported.

config =
  plugins:
    sass:
      sourceMapEmbed: true

To include the source files' name/path in either debug mode, create a parent file that @include your actual sass/scss source. Make sure the source files are renamed to start with an underscore (_file.scss), or otherwise exclude them from the build so they don't get double-included.

To pass any other options to sass:

config =
  plugins:
    sass:
      options: ['--quiet']

Use sass/compass installed in custom location:

config =
  plugins:
    sass:
      gem_home: './gems'

This could be useful for the environment which doesn't allow to install gems globally, such as CI server.

Use libsass experimental custom functions:

types = require('node-sass').types
config =
  plugins:
    sass:
      mode: 'native' # custom functions are only supported in 'native' mode
      functions:
        sin: (val) -> types.Number(Math.sin(val.getValue()))
        cos: (val) -> types.Number(Math.cos(val.getValue()))
        tan: (val) -> types.Number(Math.tan(val.getValue()))

CSS Modules

Starting Brunch 2.6.0, you can use CSS Modules with css-brunch. To enable it, change your config to:

module.exports = {
  // ...
  plugins: {
    sass: {
      modules: true
    }
  }
};

You can also pass options directly to postcss-modules:

module.exports = {
  // ...
  plugins: {
    sass: {
      modules: {
        generateScopedName: '[name]__[local]___[hash:base64:5]'
      }
    }
  }
};

Then, author your styles like you normally would:

.title {
  font-size: 32px;
}

And reference CSS class names by requiring the specific style into your javascript:

var style = require('./title.scss');

<h1 className={style.title}>Yo</h1>

Note: enabling cssModules does so for every stylesheet in your project, so it's all-or-nothing. Even the files you don't require will be transformed into CSS modules (aka will have obfuscated class names, like turn .title into ._title_fdphn_1).
