cronsun 前端采用 vue 编写，打包后转为 go 静态代码并被一起编译为二进制包。代码目录为 cronsun/web/ui。但由于依赖库版本等问题需要修改部分构建代码。

1. 新增 cronsun/web/ui/copy-files.js

   const fs = require('fs');
   fs.copyFileSync('index.html', './dist/index.html');

2. 修改 cronsun/web/ui/package.json

   {
     "name": "cronsun-web-ui",
     "version": "1.0.0",
     "description": "",
     "scripts": {
       "dev": "cross-env NODE_ENV=development webpack-dev-server --open --inline --hot --disableHostCheck=true",
       "build": "cross-env NODE_ENV=production webpack --progress --hide-modules && node copy-files.js",
       "test": "echo \"Error: no test specified\" && exit 1"
     },
     "private": true,
     "author": "heshitan@sunteng.com",
     "dependencies": {
       "chart.js": "^2.5.0",
       "core-js": "^3.36.1",
       "jquery": "^3.1.1",
       "jquery.cookie": "^1.4.1",
       "semantic-ui": "^2.5.0",
       "vue": "^2.3.4",
       "vue-router": "^2.2.1",
       "vuex": "^2.3.1"
     },
     "devDependencies": {
       "babel-core": "^6.0.0",
       "babel-loader": "^6.0.0",
       "babel-preset-es2015": "^6.0.0",
       "cross-env": "^3.0.0",
       "css-loader": "^0.26.1",
       "file-loader": "^0.9.0",
       "style-loader": "^0.13.1",
       "vue-loader": "^10.0.0",
       "vue-template-compiler": "^2.3.4",
       "webpack": "^2.1.0-beta.25",
       "webpack-dev-server": "^2.1.0-beta.9"
     }
   }
   

3. 修改 cronsun/web/ui/webpack.config.js

   var path = require('path')
   var webpack = require('webpack')
   
   var fontPublicPath = process.env.NODE_ENV === 'production' ? '/ui/' : '';
   module.exports = {
     entry: path.resolve(__dirname, 'src', 'main.js'),
     output: {
       path: path.resolve(__dirname, './dist'),
       publicPath: '/',
       filename: 'build.js'
     },
     module: {
       rules: [
         {
           test: /\.vue$/,
           loader: 'vue-loader',
           options: {
             loaders: {
               // Since sass-loader (weirdly) has SCSS as its default parse mode, we map
               // the "scss" and "sass" values for the lang attribute to the right configs here.
               // other preprocessors should work out of the box, no loader config like this nessessary.
               'scss': 'vue-style-loader!css-loader!sass-loader',
               'sass': 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
             }
             // other vue-loader options go here
           }
         },
         {
           test: /\.js$/,
           loader: 'babel-loader',
           exclude: /node_modules/
         },
         {
           test: /\.(png|jpg|gif|svg|ttf|woff|woff2|eot)\w*/,
           loader: 'file-loader',
           options: {
             publicPath: fontPublicPath,
             name: '[name].[ext]?[hash]'
           }
         },
         {
           test: /\.css$/,
           loader: 'style-loader!css-loader'
         }
       ]
     },
     resolve: {
       alias: {
         'vue$': 'vue/dist/vue.common.js',
         'semantic$': 'semantic-ui/dist/semantic.min.js',
         'semanticcss$': 'semantic-ui/dist/semantic.min.css',
         'charts$': 'chart.js/dist/Chart.min.js'
       }
     },
     devServer: {
       proxy: {
         '/v1': {
           target: 'http://127.0.0.1:7079',
           secure: false
         }
       },
       historyApiFallback: true,
       noInfo: true
     },
     performance: {
       hints: false
     },
     devtool: '#eval-source-map'
   }
   
   if (process.env.NODE_ENV === 'production') {
     module.exports.devtool = '#source-map'
     // http://vue-loader.vuejs.org/en/workflow/production.html
     module.exports.plugins = (module.exports.plugins || []).concat([
       new webpack.DefinePlugin({
         'process.env': {
           NODE_ENV: '"production"'
         }
       }),
       new webpack.LoaderOptionsPlugin({
         minimize: true
       })
     ])
   }

4. node 版本为 14.21.3 (可以采用 nvm 进行管理)

   mac M 芯片此版本安装需要 rosetta [在 Apple Silicon M1/M2 Mac 电脑上安装 Rosetta 2 运行 intel 应用](https://macoshome.com/course/6879.html)

   > cronsun/web/ui
   npm install semantic-ui --ignore-scripts
   npm i
   npm run build

5. 通过脚本将前端代码转为 go 静态文件

   > cronsun/web
   sh gen_bindata.sh

6. 构建 go 二进制文件

   > cronsun
   sh build.sh

   生成的二进制文件就在 cronsun/dist 下
