ember-cli-sass

Use node-sass to preprocess your ember-cli app's files, with support for source maps and include paths.

Installation

npm install --save-dev ember-cli-sass

Usage

By default this addon will compile app/styles/app.scss or app/styles/app.sass into dist/assets/app.css and produce a source map for your delectation.

Or, if you want more control then you can specify options using the sassOptions config property in the Brocfile:

var app = new EmberApp({
  sassOptions: {...}
});

.includePaths: an array of include paths
.sourceMap: controls whether to generate sourceMaps, defaults to true in development. The sourceMap file will be saved to options.outputFile + '.map'
.extension: optionally specify the file extension for the input files. If not specified then the filesystem is checked for the existence of an scss or sass file. Please note that, at this point in time, you must specify this option when using ember-cli-sass inside an addon
See broccoli-sass-source-maps for a list of other supported options.

Processing multiple files

If you need to process multiple files, it can be done by configuring the output paths in your Brocfile.js:

var app = new EmberApp({
  outputPaths: {
    app: {
      css: {
        'app': '/assets/application-name.css',
        'themes/alpha': '/assets/themes/alpha.css'
      }
    }
  }
});

Upgrading from a previous version

In a previous versions the sassOptions config property was incorrectly moved to the config/environment.js file. This usage is deprecated, and you should specify the config in the Brocfile.

If you were using the .inputFile and .outputFile options, this is now done by configuring the output paths in your Brocfile.js

Example

The following example assumes your bower packages are installed into bower_components/.

Install some SASS:

bower install --save foundation

Specify some include paths in your Brocfile:

var app = new EmberApp({
  sassOptions: {
    includePaths: [
      'bower_components/foundation/scss'
    ]
  }
});

Import some deps into your app.scss:

@import 'foundation'; /* import everything */
/* or just import the bits you need: @import 'foundation/functions'; */

Addon Usage

To compile SASS within an ember-cli addon, there are a few additional steps:

Include your styles in addon/styles/addon.scss.
Ensure you've installed ember-cli-sass under dependencies in your package.json.

Define an included function in your app:

// in your index.js
module.exports = {
  name: 'my-addon',
  included: function(app) {
    this._super.included(app);
  }
};

If you omit this step, it will throw the following error:

Cannot read property 'sassOptions' of undefined
TypeError: Cannot read property 'sassOptions' of undefined
at Class.module.exports.sassOptions (~/my-plugin/node_modules/ember-cli-sass/index.js:43:48)

Make sure your dummy app contains an app.scss
If you run ember build dist, your styles from addon/styles/addon.scss should appear correctly in dist/assets/vendor.css

For an example of an addon that does this correctly, see ember-cli-notifications

Source Maps

Be aware that there are some issues with source maps in broccoli-sass. The source maps it generates will at least show you the source file names and line number in your dev tools. When we've got a better solution in broccoli-sass you'll be able to click through to view and update the SASS files in the dev tools \o/.
