Webpack 加载器作为外部

Question

我在 npm 上将 React 组件作为 webpack 包发布，我遵循库指南并使用 externals 和 webpack-node-externals 告诉 webpack 不要捆绑组件所依赖的库（例如 React）。我的包现在相当小，但我注意到样式加载器仍然存在，有没有办法告诉 webpack 不要捆绑 style-loader 并依赖将导入我的库/组件的项目的 style-loader ？

    webpack.config.js

   "use strict";
    var webpack = require('webpack');
    var path = require('path');
    var loaders = require('./webpack/loaders');

    var ExtractTextPlugin = require('extract-text-webpack-plugin');

    const HOST = process.env.HOST || "127.0.0.1";
    const PORT = process.env.PORT || "5000";

    const paths = {
      SRC:path.resolve(__dirname,'src'),
      HOT_RELOADER:'react-hot-loader/patch'

    module.exports = {

        path.join(paths.SRC,'index.jsx')

      devtool: process.env.WEBPACK_DEVTOOL || 'eval-source-map',
      output: {
