nodejs中使用velocity

scuess

学习nodejs框架发现都是jade，不复杂，也不想学，如果会velocity就不用再学jade了。
可以直接在nodejs中使用velocity，因为npm里有velocityjs。
用express建一个项目引用
express demo
目录如下：│  app.js            //node app.js 启动
│  package.json
│
├─public
│  ├─css
│  ├─img
│  └─js
├─routes
│      index.js
│      user.js
└─views              //vm模板
footer.vm
head.vm
index.vm
mainBody.vm改package.json(默认是jade，其实不改也没关系){
"name": "cjx",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node app.js"
},
"dependencies": {
"express": "3.4.3",
"jade": "*",
"velocityjs":"0.4.2"
}
}

稍改app.js就行/**
* Module dependencies.
