Full documentation is at jade-lang.com

Jade is a high performance template engine heavily influenced by Haml and implemented with JavaScript for node. For discussion join the Google Group.

You can test drive Jade online here.

Announcements

Deprecation of implicit script/style text-only:

Jade version 0.31.0 deprecated implicit text only support for scripts and styles. To fix this all you need to do is add a . character after the script or style tag.

It is hoped that this change will make Jade easier for newcomers to learn without affecting the power of the language or leading to excessive verboseness.

If you have a lot of Jade files that need fixing you can use fix-jade to attempt to automate the process.

Command line option change:

since v0.31.0, -o is preferred for --out where we used -O before.

Installation

via npm:

$ npm install jade

Syntax

Jade is a clean, whitespace sensitive syntax for writing html. Here is a simple example:

doctype 5
html(lang="en")
  head
    title= pageTitle
    script(type='text/javascript').
      if (foo) bar(1 + 5)
  body
    h1 Jade - node template engine
    #container.col
      if youAreUsingJade
        p You are amazing
      else
        p Get on it!
      p.
        Jade is a terse and simple templating language with a
        strong focus on performance and powerful features.

becomes

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>Jade</title>
    <script type="text/javascript">
      if (foo) bar(1 + 5)
    </script>
  </head>
  <body>
    <h1>Jade - node template engine</h1>
    <div id="container" class="col">
      <p>You are amazing</p>
      <p>Jade is a terse and simple templating language with a strong focus on performance and powerful features.</p>
    </div>
  </body>
</html>

The official jade tutorial is a great place to start. While that (and the syntax documentation) is being finished, you can view some of the old documentation here and here

API

For full API, see jade-lang.com/api

var jade = require('jade');

// compile
var fn = jade.compile('string of jade', options);
var html = fn(locals);

// render
var html = jade.render('string of jade', merge(options, locals));

// renderFile
var html = jade.renderFile('filename.jade', merge(options, locals));

Options

  • filename Used in exceptions, and required when using includes
  • compileDebug When false no debug instrumentation is compiled
  • pretty Add pretty-indentation whitespace to output (false by default)

Browser Support

The latest version of jade can be download for the browser in standalone form from here. It only supports the very latest browsers though, and is a large file. It is recommended that you pre-compile your jade templates to JavaScript and then just use the runtime.js library on the client.

To compile a template for use on the client using the command line, do:

$ jade --client --no-debug filename.jade

which will produce filename.js containing the compiled template.

Command Line

After installing the latest version of node, install with:

$ npm install jade -g

and run with

$ jade --help
