JADE To HTML - Complete Guide

Jade to HTML converter transforms Jade template syntax into standard HTML markup. Jade (now called Pug) is a high-performance template engine with clean, whitespace-sensitive syntax that compiles to HTML. Essential for legacy Jade projects and learning template engines.

How It Works

Parse Jade syntax (indentation-based structure, tag shortcuts, attributes in parentheses) and convert to HTML. Handle mixins, includes, extends, conditionals, and iterations. Generate properly indented, valid HTML output.

Technical Details

Jade uses indentation for nesting (like Python), tag names without brackets (div, p, span), classes/ids with CSS selectors (div.class#id), attributes in parentheses. Jade was renamed to Pug in 2016 due to trademark issues. Same syntax, different name.

Common Use Cases

  1. Legacy Projects: Convert old Jade templates to HTML.
    • Example: Migrate from Jade to static HTML
  2. Learning: Understand what Jade compiles to.
  3. Debugging: See the HTML output for template issues.
  4. Static Generation: Generate static HTML from Jade source.

Code Examples

Jade to HTML Conversion

// Jade input:
doctype html
html(lang="en")
  head
    meta(charset="UTF-8")
    title My Page
    link(rel="stylesheet", href="style.css")
  body
    header.main-header
      nav#main-nav
        ul
          each item in ['Home', 'About', 'Contact']
            li
              a(href="#")= item
    main.content
      h1 Welcome
      p.intro This is a paragraph with a #[strong bold word].
      if showButton
        button.btn.btn-primary Click me
    footer
      p © 2024

// HTML output:
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <title>My Page</title>
    <link rel="stylesheet" href="style.css">
  </head>
  <body>
    <header class="main-header">
      <nav id="main-nav">
        <ul>
          <li><a href="#">Home</a></li>
          <li><a href="#">About</a></li>
          <li><a href="#">Contact</a></li>
        </ul>
      </nav>
    </header>
    <main class="content">
      <h1>Welcome</h1>
      <p class="intro">This is a paragraph with a <strong>bold word</strong>.</p>
      <button class="btn btn-primary">Click me</button>
    </main>
    <footer>
      <p>&copy; 2024</p>
    </footer>
  </body>
</html>

Jade uses indentation for nesting, CSS selectors for classes/ids, and parentheses for attributes. Much cleaner than HTML.

Tips & Best Practices

  • Consistent indentation (2 spaces recommended)
  • div is default tag: .class = div.class
  • Use | for plain text lines
  • Use = for buffered output, - for unbuffered code
  • Pug is the current name; use pug package

Common Mistakes to Avoid

  • Inconsistent indentation (mixing tabs/spaces)
  • Forgetting closing parenthesis in attributes
  • Using HTML tags with brackets in Jade
  • Wrong indentation level for nesting
  • Using deprecated jade package instead of pug

When to Use This Tool

Use Jade to HTML converter when working with legacy Jade templates, learning template syntax, or generating static HTML from Jade source files.

Frequently Asked Questions

What's the difference between Jade and Pug?

Same thing. Jade was renamed to Pug in 2016 due to trademark issues. Syntax is identical. If using a package, use "pug" not "jade" as jade package is deprecated.

Why use Jade/Pug over HTML?

Cleaner syntax, no closing tags, CSS-like selectors for classes/ids, built-in templating (loops, conditionals), includes/extends for reusability. Great for server-side rendering.

Does whitespace matter?

Yes! Jade uses indentation for nesting (2 spaces or tabs, be consistent). Wrong indentation breaks structure. This is the main learning curve from HTML.

Can I use JavaScript in Jade?

Yes. Unbuffered code: - var x = 5. Buffered output: = variable or #{variable}. Conditionals: if/else. Loops: each item in items. Full JS expressions supported.
