NODE_ENV判断node服务器环境的设置

build->webpack.sit.conf.js 

拷贝webpack.prod.conf.js，新建webpack.sit.conf.js、webpack.uait.conf.js ,根据环境修改env的引入文件

config->sit.env.js

 build->bulid.js

src -> config文件夹 -> index.js

package.json

修改package.json配置，实现不同环境包的打包命令

npm run build:sit    //打包sit包
npm run build:uat    //打包uat包
npm run build          //打包生产包

1、安装 cross-env ：cross-env能跨平台设置及使用环境变量

npm install cross-env --save

2、修改scripts部分：配置跨平台环境变量

.gitignore
