我也有同样的问题，必须满足以下所有要求:

缩小版+非缩小版(如问题所示) ES6 跨平台(Windows + Linux)。

我最终解决如下:

webpack.config.js:

const path = require('path');
const MinifyPlugin = require("babel-minify-webpack-plugin");

module.exports = getConfiguration;

function getConfiguration(env) {
    var outFile;
    var plugins = [];
    if (env === 'prod') {
        outFile = 'mylib.dev';
        plugins.push(new MinifyPlugin());
    } else {
        if (env !== 'dev') {
            console.log('Unknown env ' + env + '. Defaults to dev');
        }
        outFile = 'mylib.dev.debug';
    }

    var entry = {};
    entry[outFile] = './src/mylib-entry.js';

    return {
        entry: entry,
        plugins: plugins,
        output: {
            filename: '[name].js',
            path: __dirname
        }
    };
}

package.json:

{
    "name": "mylib.js",
    ...
    "scripts": {
        "build": "npm-run-all webpack-prod webpack-dev",
        "webpack-prod": "npx webpack --env=prod",
        "webpack-dev": "npx webpack --env=dev"
    },
    "devDependencies": {
        ...
        "babel-minify-webpack-plugin": "^0.2.0",
        "npm-run-all": "^4.1.2",
        "webpack": "^3.10.0"
    }
}

然后我可以通过(不要忘记npm install之前):

npm run-script build

要添加另一个答案，flag -p(——optimize- minimal的缩写)将启用带有默认参数的UglifyJS。

您不会在一次运行中获得一个缩小的原始包，也不会生成不同名称的包，因此-p标志可能不符合您的用例。

相反，-d选项是——debug——devtool sourcemap——output-pathinfo的缩写

我的webpack.config.js省略了devtool、debug、pathinfo和最小化插件，取而代之的是这两个标志。

你应该像这样导出一个数组:

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

const libName = 'YourLibraryName';

function getConfig(env) {
  const config = {
    mode: env,
    output: {
      path: path.resolve('dist'),
      library: libName,
      libraryTarget: 'umd',
      filename: env === 'production' ? `${libName}.min.js` : `${libName}.js`
    },
    target: 'web',
    .... your shared options ...
  };

  return config;
}

module.exports = [
  getConfig('development'),
  getConfig('production'),
];

你可以在webpack配置中定义两个入口点，一个用于普通js，另一个用于迷你js。然后你应该输出你的bundle和它的名字，并配置UglifyJS插件来包含min.js文件。请参阅webpack配置示例了解更多细节:

module.exports = {
 entry: {
   'bundle': './src/index.js',
   'bundle.min': './src/index.js',
 },

 output: {
   path: path.resolve(__dirname, 'dist'),
   filename: "[name].js"
 },

 plugins: [
   new webpack.optimize.UglifyJsPlugin({
      include: /\.min\.js$/,
      minimize: true
   })
 ]
};

运行webpack后，你会在dist文件夹中得到bundle.js和bundle.min.js，不需要额外的插件。

根据这一行:https://github.com/pingyuanChen/webpack-uglify-js-plugin/blob/master/index.js#L117

应该是这样的:

var webpack = require("webpack");

module.exports = {

  entry: "./entry.js",
  devtool: "source-map",
  output: {
    path: "./dist",
    filename: "bundle.js"
  },
  plugins: [
    new webpack.optimize.UglifyJsPlugin({
     minimize: true,
     compress: false
    })
  ]
};

实际上，通过根据env / argv策略导出不同的配置，您可以拥有多个构建。
