这是我的webpack.config.js

var webpack = require("webpack");

module.exports = {

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

我用

$ webpack

在dist文件夹里,我只得到

bundle.min.js bundle.min.js.map

我还想看看未压缩的bundle.js

你可以为webpack创建两个配置,一个可以减少代码,另一个则不能(只需删除优化)。然后同时运行两个配置$ webpack && webpack——config webpack.config.min.js

也许我来晚了,但我也有同样的问题,所以我为此写了一个unminifiedwebpack插件。

安装

npm install --save-dev unminified-webpack-plugin

使用

var path = require('path');
var webpack = require('webpack');
var UnminifiedWebpackPlugin = require('unminified-webpack-plugin');

module.exports = {
    entry: {
        index: './src/index.js'
    },
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'library.min.js'
    },
    plugins: [
        new webpack.optimize.UglifyJsPlugin({
            compress: {
                warnings: false
            }
        }),
        new UnminifiedWebpackPlugin()
    ]
};

通过上述操作,您将得到library.min.js和library.js两个文件。不需要执行webpack两次,它只是工作!^ ^

我找到了解决这个问题的新方法。

这使用了一个配置数组,使webpack能够并行地构建精简版和非精简版。这使得构建更快。不需要运行webpack两次。不需要额外的插件。只是webpack。

webpack.config.js

const devConfig = {
  mode: 'development',
  entry: { bundle: './src/entry.js' },
  output: { filename: '[name].js' },
  module: { ... },
  resolve: { ... },
  plugins: { ... }
};

const prodConfig = {
  ...devConfig,
  mode: 'production',
  output: { filename: '[name].min.js' }
};

module.exports = (env) => {
  switch (env) {
    case 'production':
      return [devConfig, prodConfig];
    default:
      return devConfig;
  }
};

运行webpack将只生成非缩小版本。

运行webpack——env=production将同时构建缩小版和非缩小版。

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

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'),
];
