Vue CLI 3 vue.config.js 与 webpack.config.js 插件

我正在使用 Vue CLI 3，我需要添加更简洁的 Webpack 插件 https://webpack.js.org/plugins/terser-webpack-plugin/用于去除控制台日志 and comments从代码中。这不适用于我当前的设置 - 日志和注释仍在构建中。我的制作流程：

1. Run npm run build
2. Run serve -s dist

vue.config.js：

module.exports = {
  publicPath: "./"
}

webpack.config.js：

const TerserPlugin = require('terser-webpack-plugin');

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
      new TerserPlugin({
        terserOptions: {
          ecma: undefined,
          warnings: false,
          parse: {},
          compress: { drop_console: true },
          mangle: true, // Note `mangle.properties` is `false` by default.
          module: false,
          output: { comments: false },
          toplevel: false,
          nameCache: null,
          ie8: false,
          keep_classnames: undefined,
          keep_fnames: false,
          safari10: false,
        },
      }),
    ],
  },
};

我需要改变什么才能让它发挥作用？是webpack.config.js代码的正确位置？

在Vue CLI项目中，Webpack配置在<projectRoot>/vue.config.js https://cli.vuejs.org/config/#vue-config-js通过configureWebpack https://cli.vuejs.org/guide/webpack.html#simple-configuration or chainWebpack https://cli.vuejs.org/guide/webpack.html#chaining-advanced特性。您可以从命令行检查已解析的 Webpack 配置vue inspect https://cli.vuejs.org/guide/webpack.html#inspecting-the-project-s-webpack-config.

根据您的情况，添加一个<projectRoot>/vue.config.js包含以下内容：

const TerserPlugin = require('terser-webpack-plugin')

module.exports = {
  configureWebpack: config => {
    config.optimization = {
      minimize: true,
      minimizer: [
        new TerserPlugin({
          terserOptions: {
            ecma: undefined,
            warnings: false,
            parse: {},
            compress: { drop_console: true },
            mangle: true, // Note `mangle.properties` is `false` by default.
            module: false,
            output: { comments: false },
            toplevel: false,
            nameCache: null,
            ie8: false,
            keep_classnames: undefined,
            keep_fnames: false,
            safari10: false,
          },
        }),
      ],
    }
  }
}
