broccoli-eyeglass

broccoli-eyeglass is a broccoli plugin that compiles .scss and .sass files with libsass and uses eyeglass for project and sass module support.

Installation

npm install --save-dev broccoli-eyeglass

Usage

In your Brocfile.js:

var compileSass = require('broccoli-eyeglass');

var outputDirectory = "dist";
var options = {
  cssDir: "assets/css",
  fullException: false
}
var outputTree = new compileSass(inputTrees, options);

• inputTrees: An array of trees that act as the include paths for libsass. If you have a single tree, pass [tree]. All sass files in these trees that are not prefixed with an underscore (a.k.a. a partial), will be compiled into a single output directory. Use the node-sass includePaths option to make other directories available for import without compiling them to css. Note that eyeglass will make sure that all your eyeglass-compatible sass modules can be imported.

• options: Except for the options that are specific to this plugin. All the rest are passed through eyeglass and then to node-sass.

Note: that the following node-sass options are managed by this plugin and must not be provided: file, data, outFile

Options

The following options are specific to this plugin:

• cssDir - Required. The directory where CSS files should be written relative to the build output directory.

• sassDir - The directory to look for scss files to compile. Defaults to tree root.

• renderSync - Force sass rendering to use node-sass's synchronous rendering. Defaults to false.

• fullException - When set to true, instead of generating a build error, the css output file will be written such that it displays a compilation failure in the browser. This is useful during development but should not be used for production builds. (Not yet implemented)

• verbose - When true, console logging will occur for each css file that is built along with timing information.

• discover - When true, will discover sass files to compile that are found in the sass directory. Defaults to true unless sourceFiles are specified.

• sourceFiles - Array of file names or glob patterns (relative to the sass directory) that should be compiled.

• optionsGenerator - Function that accepts four arguments:

  • sassFile - The sass file being compiled.
  • cssFile - The place where broccoli-eyeglass plans to write the cssFile relative to the build output directory.
  • options - The compilation options that will be passed to eyeglass and then to node-sass. This is a copy of plugin's options and so it can be modified or augmented.
  • compilationCallback - This callback accepts a css filename and options to use for compilation. This callback can be invoked 0 or more times. Each time it is invoked, the sass file will be compiled to the provided css file name (relative to the output directory) and the options provided.

  In this way a sass file can be skipped or permuted during your build process by passing different options. Examples where this is useful include A/B testing or localization specific output. Note: if you invoke the callback more than once, you should change the output filename to avoid overwriting previous invocations' output.
