ember-cli-postcss

Use postcss to process your css with a large selection of JavaScript plug-ins.

Installation

npm install --save-dev ember-cli-postcss

Usage

The addon is still a little rough around the edges, but it will look for either app.css or <project-name>.css in your styles directory. Postcss requires at least one plug-in to actually do any processing, and so broccoli-postcss will throw an error if at least one is not provided.

Configuring Plug-ins

There are two steps to setting up postcss with ember-cli-postcss:

1. install and require the node modules for any plug-ins
2. provide the node module and plug-in options as a postcssOptions object in the Brocfile

The postcssOptions object should have a property plugins, which is an array of objects that contain a module property and an options property:

postcssOptions: {
  plugins: [
    {
      module: <module>,
      options: {
        ...
      }
    }
  ]
}

Example

Install the autoprefixer plugin:

npm i --save-dev autoprefixer-core

Specify some plugins in your Brocfile.js:

var EmberApp = require('ember-cli/lib/broccoli/ember-app');
var autoprefixer = require('autoprefixer-core');

var app = new EmberApp({
  postcssOptions: {
    plugins: [
      {
        module: autoprefixer,
        options: {
          browsers: ['last 2 version']
        }
      }
    ]
  }
});

module.exports = app.toTree();
