Usage

When you want to trasform url(/assets/...) to url(https://domain/assets/...), the webpack.config.js is below

module.exports = {
  ...
  module: {
    rules: [
      ...
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            'css-loader',
            {
              loader: 'css-fix-url-loader',
              query: {
                from: '/assets/',
                to: 'https://domain/assets/'
              }
            }
          ],
        }),
      },
      ...
    ],
  },
  plugins: [
    ...
    new ExtractTextPlugin('bundle.css'),
    ...
  ],

When you want to trasform url(/assets/...) to url(/dir/assets/...), the webpack.config.js is below

module.exports = {
  ...
  module: {
    rules: [
      ...
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            'css-loader',
            {
              loader: 'css-fix-url-loader',
              query: {
                from: '/assets/',
                to: '/dir/assets/'
              }
            }
          ],
        }),
      },
      ...
    ],
  },
  plugins: [
    ...
    new ExtractTextPlugin('bundle.css'),
    ...

          use: [
            'css-loader',
            {
              loader: 'css-fix-url-loader',
              query: {
                from: '/assets/',
                to: '/tmp/assets/',
                env: 'development'
              }
            }
          ],
        }),
      },
      ...

    new ExtractTextPlugin('bundle.css'),
    ...
  ],
