crossplaform---Nodejs in Visual Studio Code 04.Swig模版
1.开始
设置Node_Global:npm config set prefix "C:\Program Files\nodejs"
Express组件:npm install express -g(全局安装)
Express-Generator:npm install express-generator -g(全局安装)
如果没有设置global可能导致express命令在cmd里面无法执行
我接触过3个模版jade,ejs,swig,最后选择了swig
jade :是express的默认View模版,jade的功能强大(模版继承、判断、循环、变量等),然而风格我忍不了,放出来感受一下;

extends layout block content h1= title p Welcome to #{title} |
ejs : 看起来像是html了,风格我喜欢,但是里面把模版要素和js混用看着很纠结,如果写到后面很难维护 ,最重要的是功能没有jade那么多,弃用原因2是不支持模版继承;

<% if (names.length) { %> <ul> <% names.forEach( function (name){ %> <li foo= '<%= name + "' " %>'><%= name %></li> <% }) %> </ul> <% } %> |
swig :缺点是搜索结果比ejs、jade少很多,然而支持继承,功能比ejs强大,又是html风格的,没有和js混用的缺点,棒棒哒;

<! doctype html> < html > < head > < meta charset="utf-8"> < title >{% block title %}My Site{% endblock %}</ title > {% block head %} < link rel="stylesheet" href="main.css"> {% endblock %} </ head > < body > {% block content %}{% endblock %} </ body > </ html > |
注:上表Swig最强参考 http://paularmstrong.github.io/node-templates/
2.改造Express默认模版使用swig作为ViewEngine
打开CMD使用命令新建一个Express Example

$ cd D:\Libraries\Documents\Visual Studio Code $ express myapp create : myapp create : myapp /package .json ...... install dependencies: > cd myapp && npm install run the app: > SET DEBUG=myapp:* & npm start |
修改package.json文件,将jade替换为swig
修改app.js将jade viewengine替换为swig viewengine
修改后:swig ViewEngine
