Pug - Node Template Engine

Pug has been recently re-named from Jade. The website and documentation are still being updated, but if you're new to pug, you should install the pug package on npm.

Full documentation is at

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

via npm:

$ npm install pug


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

doctype html
    title= pageTitle
      if (foo) bar(1 + 5)
    h1 Pug - node template engine
      if youAreUsingPug
        p You are amazing
        p Get on it!
        Pug is a terse and simple templating language with a
        strong focus on performance and powerful features.


<!DOCTYPE html>
<html lang="en">
    <script type="text/javascript">
      if (foo) bar(1 + 5)
    <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>

The official Pug tutorial is a great place to start.


For full API, see

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)

Browser Support

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.

Command Line

After installing the latest version of node, install with:

$ npm install pug-cli -g

and run with

$ pug --help
