Webpack loader to transform url() to es6 imports inside the css or sass when using separate files to create styled-jsx styles.
This loader needs to be used together with styled-jsx/webpack loader.
It's similar to what css-loader does, but css-loader is incompatible with styled-jsx/webpack loader.

Using yarn:

yarn add styled-jsx-url-loader --dev

Or using npm:

npm install styled-jsx-url-loader --dev

This loader should be executed right after styled-jsx/webpack and before babel loader.
Since loaders are executed from last to first, usage can be like this (with next.js):

config.module.rules.push({
  test: /\.s?css$/,
  use: [
    options.defaultLoaders.babel,
    {
      loader: require.resolve('styled-jsx-url-loader'),
      options: {},
    },
    {
      loader: require('styled-jsx/webpack').loader,
      options: {
        type: 'scoped',
      },
    },
  ],
})

Type: Boolean
Default: false

Allow parsing scss code.
(It will not transform scss to css, only allow parser to parse it)

Type: String|RegExp
Default: null

Exclude urls from transformations.

Type: Boolean
Default: false

Print debug messages.

Sass variables inside the urls are not supported. For example: background: url($heroImage).
If you need to transform urls with variables, transform your sass code first to plain css.

There is no source maps support. (PR welcome)
