Question

开发wordpress网站并使用webpack捆绑资产。

我有一个将SCSS编译为CSS的设置。我想缩小输出CSS并删除注释。我试图添加 optimize-css-assets-webpack-plugin 并将其配置为as example suggests，但是它不起作用（没有错误）...

那么我该如何修改此webpack配置，以使输出（1）去除注释并缩小（2）？

webpack.config.js：

const path = require("path");
const config = require('./config.js');
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');

module.exports = {
  mode: 'production',
  entry: ["./src/app.js", "./src/scss/style.scss"],
  output: {
    path: path.resolve(__dirname, "wp-content/themes/ezdigital"),
    filename: "js/[name].js"
  },
  module: {
    rules: [
      {
        test: /\.scss$/,
        use: [
          {
            loader: "file-loader",
            options: {
              name: "[name].css"
            }
          },
          {
            loader: "extract-loader"
          },
          {
            loader: "css-loader?-url"
          },
          {
            loader: "postcss-loader"
          },
          {
            loader: "sass-loader"
          }
        ]
      },
      {
        test: /\.js$/,
        exclude: /(node_modules)/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["env"]
          }
        }
      },
      {
        test: /\.(png|svg|jpg|gif)$/,
        use: ["file-loader"]
      }
    ]
  },
  //remove comments from JS files
  optimization: {
    minimizer: [
      new UglifyJsPlugin({
        uglifyOptions: {
          output: {
            comments: false,
          },
        },
      }),
    ],
  },
  plugins: [
    new BrowserSyncPlugin( {
            proxy: config.url,
            files: [
                '**/*.php'
            ],
            reloadDelay: 0
        }
  )
]

};

其他postss.config.js：

module.exports = {
    plugins: {
        'autoprefixer': {}
    }
}

Package.json：

原来的问题是我试图使用 extract-text-webpack-plugin ，该功能不适用于webpack4。

我改为使用 mini-css-extract-plugin 和 optimize-css-assets-webpack-plugin 。

我的新webpack.config.js文件：
