Pug is a high performance template engine heavily influenced by Haml and implemented with JavaScript for Node.js and browsers. For bug reports, feature requests and questions, open an issue. For discussion join the chat room.

You can test drive Pug online here.

This project was formerly known as "Jade." However, it has been revealed to us that "Jade" is a registered trademark, and as a result a rename is needed. After some discussion among the maintainers, "Pug" has been chosen as the new name for this project. The next major version will carry "pug" as the package name.

If your package or app currently uses jade, don't worry: we have secured permissions to continue to occupy that package name, although all new versions will be released under pug.

Before the renaming, we had already begun working on an incompatible Jade 2.0.0. We have then made it so that this new major version bump will coincide with the rename to Pug. Therefore, upgrading from Jade to Pug will be the same process as upgrading any other package with a major version bump. Currently, Pug 2.0.0 is still under beta stage, and there are several syntactic differences we have deprecated and removed. Such differences are documented at #2305.

The website and documentation for Pug are still being updated, but if you are new to Pug, you should get started with the new syntax and install the Pug package on npm.

via npm:

$ npm install pug

After installing the latest version of Node.js, install with:

$ npm install pug-cli -g

and run with

$ pug --help

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

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

becomes

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

The official Pug tutorial is a great place to start.

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

var pug = require('pug');
 
// compile 
var fn = pug.compile('string of pug', options);
var html = fn(locals);
 
// render 
var html = pug.render('string of pug', merge(options, locals));
 
// renderFile 
var html = pug.renderFile('filename.pug', merge(options, locals));
  • 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)

The latest version of pug 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 pug 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:

$ pug --client --no-debug filename.pug

which will produce filename.js containing the compiled template.
