autoprefixer-loader

autoprefixer-loader

An autoprefixer loader for webpack.

Usage

var css = require('!raw!autoprefixer!./file.css'); // Just the CSS
var css = require('!css!autoprefixer!./file.css'); // CSS with processed url(...)s

See css-loader to see the effect of processed url(...)s.

Or within the webpack config:

module: {
  loaders: [{
    test: /\.css$/,
    loader: 'css-loader!autoprefixer-loader?browsers=last 2 version'
  }]
}

Then you can: var css = require('./file.css');.

Use in tandem with the style-loader to add the css rules to your document:

module: {
  loaders: [{
    test: /\.css/,
    loader: 'style-loader!css-loader!autoprefixer-loader'
  }]
}

and then require('./file.css'); will compile and add the CSS to your page.

Options

browsers

Specify a single browser to support. Read more

loaders: [{
  loader: 'css-loader!autoprefixer-loader?browsers=last 2 version',

  loader: 'css-loader!autoprefixer-loader?cascade=false',
