首先新建文件index.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="/style.css">
</head>
<body>
<h1>hello, world! <small>by 老雷</small></h1>
<hr>
<p>今天的天气真好，万里<strong>无云</strong>。</p>
<p>今天的天气真好，万里<strong>无云</strong>。</p>
<p>今天的天气真好，万里<strong>无云</strong>。</p>
</body>
</html>新建文件style.css：
body {
background: #f8f8f8;
color: #555555;
width: 80%;
margin: 100px auto 50px auto;
}
h1 {
text-align: center;
color: blueviolet;
}
small {
font-size: 40%;
}
p {
margin: 2em 0;
font-size: 18px;
border: 1px solid deepskyblue;
padding: 4px;
cursor: pointer;
}
p:hover {
background: yellowgreen;
}新建文件index.js：
console.log('hello, world');在当前项目根目录下执行以下命令：
$ devserver start -w -o -p 8000稍等几秒，服务器启动后会自动在浏览器打开地址http://127.0.0.1:8000即可看到显示的页面。
说明：
- 如果启动服务器时使用了
-w参数，则当目录下的任意文件有改动时，在浏览器中打开的HTML会自动刷新 - 在 JavaScript 文件内，可以使用
require()来载入模块，实际上会通过 Browserify 来进行打包
