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: '/',
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）
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
