How to use postcss-js with Webpack? SyntaxError: Unexpected token export

[mahnunchik]

I've faced with the following error:

ERROR in ./src/test.style.js
Module build failed: /test-webpack/src/test.style.js:3
export default {
^^^^^^

SyntaxError: Unexpected token export

    at Object.runInThisContext (vm.js:116:10)
    at Module._compile (module.js:533:28)

    at Promise.resolve.then.then (/test-webpack/node_modules/postcss-loader/lib/index.js:109:18)
    at <anonymous>

My webpack.config.js:

const path = require('path');
const webpack = require('webpack');

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: 'babel-loader',
        },
      },
      {
        test: /\.style.js$/,
        use: [
          'style-loader',
          { loader: 'css-loader', options: { importLoaders: 2 } },
          { loader: 'postcss-loader', options: { parser: 'postcss-js' } },
          'babel-loader'
        ]
      },
    ],
  },
};

index.js:

import React from 'react';
import ReactDOM from 'react-dom';

import style from './test.style.js';

class Hello extends React.Component {
  render() {
    return <div style={style.main}>Hello World!</div>;
  }
}

ReactDOM.render(
  <Hello />,
  document.getElementById('root')
);

test.style.js:

export default {
  'main': {
    color: 'black',
    height: 25,
    display: 'flex',
  }
}

You should ask postcss-loader, because issue goes from webpack config
