1、在build文件夹中创建testing.js文件
// 配置环境变量 type 为 testing process.env.type = '"testing"' // 引入build.js文件 require('./build')
2、修改config文件夹中的prod.env.js文件
module.exports = { NODE_ENV: '"production"', // 将上文设置的环境变量，赋值到 type 属性上 type: process.env.type }
3、在package.json文件中添加npm run testing命令
"testing": "node build/testing.js", // 添加testing命令 "build": "node build/build.js"
4、config ->index.js中把build这个命令复制一份改成testing(此步为了打包到不同文件夹)
build: { env: require('./prod.env'), // Template for index.html index: path.resolve(__dirname, '../dist/index.html'), // Paths assetsRoot: path.resolve(__dirname, '../dist'), assetsSubDirectory: 'static', assetsPublicPath: '/mshop/', /** * Source Maps */ productionSourceMap: true, // https://webpack.js.org/configuration/devtool/#production devtool: '#source-map', // Gzip off by default as many popular static hosts such as // Surge or Netlify already gzip all static assets for you. // Before setting to `true`, make sure to: // npm install --save-dev compression-webpack-plugin productionGzip: false, productionGzipExtensions: ['js', 'css'], // Run the build command with an extra argument to // View the bundle analyzer report after build finishes: // `npm run build --report` // Set to `true` or `false` to always turn it on or off bundleAnalyzerReport: process.env.npm_config_report }, testing: { env: require('./prod.env'), index: path.resolve(__dirname, '../testing/index.html'), assetsRoot: path.resolve(__dirname, '../testing'), assetsSubDirectory: 'static', assetsPublicPath: 'https://www.jb51.net/', productionSourceMap: true, // Gzip off by default as many popular static hosts such as // Surge or Netlify already gzip all static assets for you. // Before setting to `true`, make sure to: // npm install --save-dev compression-webpack-plugin productionGzip: false, productionGzipExtensions: ['js', 'css'], // Run the build command with an extra argument to // View the bundle analyzer report after build finishes: // `npm run build --report` // Set to `true` or `false` to always turn it on or off bundleAnalyzerReport: process.env.npm_config_report },
5、修改build->webpack.prod.conf文件
修改filename
new HtmlWebpackPlugin({ filename: process.env.type == '"testing"' ? config.testing.index : config.build.index }),
修改output
output: { path: process.env.type == '"testing"' ? config.testing.assetsRoot : config.build.assetsRoot, },
6、修改build->build.js文件
路径都修改为根据正式、测试环境判断（不然执行npm run testing, npm run build命令时输出的文件有问题）
复制代码 代码如下:
rm(path.join(process.env.type == '"testing"' ? config.testing.assetsRoot : config.build.assetsRoot, process.env.type == '"testing"' ? config.testing.assetsSubDirectory : config.build.assetsSubDirectory), err => {
7、根据不同环境配置不同域名地址
let baseURL if (process.env.NODE_ENV === 'production') { if (process.env.type === 'testing') { // 测试环境 baseUrl = '测试环境地址' } else { // 正式环境 baseUrl = '正式环境地址' } } else { // 本地环境 baseUrl = '本地环境地址' }
最后执行:
npm run testing 就会执行测试环境配置的地址，并生成testing文件夹
npm run build就会执行正式环境配置的地址，并生成dist文件夹
