问使用webpack将es6类构建为单独的文件

EN

import MyComponent from 'component-kit/MyComponent';

component-kit/
   src/
     MyComponent/
       index.js
     index.js
   package.json
   webpack.config.js

import('./MyComponent');

const webpack = require('webpack');

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'dist.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['env', 'es2015', 'stage-0', 'react'],
            plugins: ['syntax-dynamic-import']
          }
        }
      }
    ]
  }
};
