大前端搭建时常用的一些命令

　　cnpm install --save *****     //安装一个脚手架运行需要的中间件

       cnpm install --save-dev ****    //安装一个开发过程中依赖的中间件

　　rm -r -f **** //强制删除一个文件夹，多用于删除node_modules目录

　　webpack  //打包的指令

　　webpack-dev-server --open //启动测试服务，并打开浏览器

webpack常用的配置如下：

var path = require('path');

const config = {
    entry: "./src/index.tsx",
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, "dist"),

    },

    resolve: {
        extensions: [".ts", ".tsx", ".js"]
    },
    module: {
