1、安装：
cnpm i webpack-dev-server -D
2、package.json中配置命令：
"dev": "webpack-dev-server --open chrome --port 3000 --hot --host 127.0.0.1"{
"name": "wp4-1",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"dev": "webpack-dev-server --open chrome --port 3000 --hot --host 127.0.0.1"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"webpack": "^4.41.5",
"webpack-cli": "^3.3.10",
"webpack-dev-server": "^3.10.1"
}
}
3、运行命令打包“npm run dev”
说明：webpack-dev-server实时打包好的main.js是托管在内存中，所以在项目根目录中看不到，但是我们可以认为在项目根目录中有一个看不见的main.js。
