可以通过NPM安装Handlebars,用命令$npm install handlebars 或$npm install handlebars --save.
示例： handlebars-example.js文件如下:
var handlebars = require('handlebars'), fs = require('fs'); var data = { title: 'practical node.js', author: { name: 'lijian', weibo: 'weibo@lijian' }, tags: ['express', 'node', 'javascript'] } data.body = process.argv[2]; fs.readFile('handlebars-example.html', 'utf-8', function(error, source){ handlebars.registerHelper('custom_title', function(title){ var words = title.split(' '); for (var i = 0; i < words.length; i++) { if (words[i].length > 4) { words[i] = words[i][0].toUpperCase() + words[i].substr(1); } } title = words.join(' '); return title; }) var template = handlebars.compile(source); var html = template(data); console.log(html) });文件handlebars-example.html中用到了helper custom_title,里面有用他输出属性的用法：
<div class="header"> <h1>{{custom_title title}}</h1> </div> <div class="body"> <p>{{body}}</p> </div> <div class="footer"> <div><a href="http://weibo.com/{{author.weibo}}">{{author.name}}</a> </div> <ul> {{#each tags}} <li>{{this}}</li> {{/each}} </ul> </div>当运行$node handlebars-example.js 'email body'时，会生成下面的HTML：
<div class="header"> <h1>Practical Node.js</h1> </div> <div class="body"> <p>'email</p> </div> <div class="footer"> <div><a href="http://weibo.com/weibo@lijian">lijian</a> </div> <ul> <li>express</li> <li>node</li> <li>javascript</li> </ul> </div>
