Do you even Jade, bro?

Making HTML fun again

What is Jade?

  • DRY HTML templating language
  • terse
  • supports dynamic code
  • uses nesting
  • clean to read and write

Tags

Tags are defined by their name, a space and then any text.

// Jade tags
ul
    li This is a bullet point
    li Another bullet point

p This is a paragraph
// HTML output
<ul>
    <li>This is a bullet point</li>
    <li>Another bullet point</li>
</ul>

<p>This is a paragraph</p>

Tag Examples

// Jade tags with attributes
img(src="cat.jpg", alt="Persian")

// HTML output
<img src="cat.jpg" alt="Persian"/>
// Jade inline syntax
ul
    li: img
    li This is some text #[span with a tag inside a span]

// HTML output
<ul>
  <li><img/></li>
  <li>This is some text <span>with an inline span</span></li>
</ul>
