broccoli-postcss-sourcemaps v2.2.0-sourcemaps.1

broccoli-postcss-sourcemaps

The broccoli-postcss-sourcemaps plugin runs your css through postcss plugins of your choosing.

This is a fork of broccoli-postcss which adds support for sourcemaps and other 1-to-many css output scenarios.

Installation

npm install --save-dev broccoli-postcss-sourcemaps

Usage

var compileCSS = require('broccoli-postcss-sourcemaps');

var outputTree = compileCSS(inputTree, options);

• inputTrees: An array of trees that specify the directories used by Broccoli. If you have a single tree, pass [tree].
• options: Options for PostCSS. Additional options are specified below.

Options not passed to PostCSS

• plugins An array of plugin objects to be used by PostCSS (a minimum of 1 plugin is required). The supported object format is module: the plugin module itself, and options: an object of supported options for the given plugin.
• resultHandler: A callback that is invoked after each file is processed by PostCSS. This can be used to process the PostCSS result messages or do other per-file operations. Note: the primary output file has not yet been written to disk when this callback is invoked. It is passed result, filter, relativePath, addOutputFile.
  • result: Object The PostCSS result object.
  • filter: Object The Broccoli Multi Filter object.
  • relativePath: String The relative path of the file being compiled.
  • addOutputFile: Function A callback that can be used to register additional output files with the Broccoli Multi Filter
