Discover Jade, a great template engine for Node
Jade is a powerful tool that makes writing HTML easier than ever. We use it extensively in our project and wanted to share our experience.
What is Jade ? #
Jade is a robust, elegant, feature rich template engine for nodejs. 1
A web template engine is a tool that allow developers to write simpler HTML, while adding some nice features that quickly become essential.
These templates are then rendered in standard, W3C-compliant HTML and are completely transparent to your users.
What does it look like ? #
As a simple example, this :
doctype html
html(lang="en")
head
title Shawt !
body
h1 Home page
ul#menu
li.menuitem Item 1
li.menuitem Item 2
li.menuitem Item 3
is rendered as :
<!DOCTYPE html>
<html lang="en">
<head>
<title>Shawt !</title>
</head>
<body>
<h1>Home page</h1>
<ul id="menu">
<li class="menuitem">Item 1</li>
<li class="menuitem">Item 2</li>
<li class="menuitem">Item 3</li>
</ul>
</body>
</html>
What about those features ? #
Jade adds some essential features to HTML, such as conditionals, loops, and mixins.
Conditionals #
- var user = { name: 'John' }
if user
div.welcomebox
// Filtered inline output
p.
Welcome, #{user.name}
else
div.loginbox
form(name="login", action="/login", method="post")
input(type="text", name="user")
input(type="password", name="pass")
input(type="submit", value="login")
is rendered as :
<div class="welcomebox">
<!-- Filtered inline output-->
<p>Welcome, John</p>
</div>
Loops #
ul
each val in [1, 2, 3, 4, 5]
li= val
is rendered as :
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
Mixins #
Mixins allow developers to create snippets to reduce redundancy and increase code reusability.
//- Declaration
mixin list
ul
li foo
li bar
li baz
//- Use
+list()
+list()
is rendered as :
<ul>
<li>foo</li>
<li>bar</li>
<li>baz</li>
</ul>
<ul>
<li>foo</li>
<li>bar</li>
<li>baz</li>
</ul>
Great then, how do I get it ? #
Jade is a great, simple tool that gives more freedom to web developers to build what they want, the way they want. We highly recommend you to try it :)
You can visit the official website [here](www.jade-lang.com), or install Jade through npm via npm install jade.
Hope this helps !
