Pug, formerly known as Jade, is a template engine for Node.js. It is used to generate HTML, XML, and other markup languages. Pug's syntax is simple and clean, making it easy to read and write. Pug uses indentation, rather than braces and semicolons, to define the structure of the HTML. It allows for the creation of reusable templates and includes features such as template inheritance and mixins. Pug also supports variables, loops and conditionals. Additionally, it can be integrated with other Node.js frameworks such as Express.

Pug helps to generate semantic, clean and reusable code, it is one of the most popular template engine for Node.js

Rename from "Jade"

This project was formerly known as "Jade". However, it was revealed to us that "Jade" is a registered trademark; as a result, a rename was needed. After some discussion among the maintainers, "Pug" was chosen as the new name for this project. As of version 2, "pug" is the official 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, work had already begun on “Jade 2.0.0”. Therefore, the rename to Pug coincided with the major version bump. As a result, upgrading from Jade to Pug will be the same process as upgrading any other package with a major version bump.

The syntax of Pug has several differences, deprecations, and removals compared to its predecessor. These differences are documented in #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 from npm.



To use Pug in your own JavaScript projects:

$ npm install pug

Command Line

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
    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.

Pug transforms the above to:

<!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>
        Pug is a terse and simple templating language with a strong focus on
        performance and powerful features.


For full API, see pugjs.org/api/reference.html

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 downloaded for the browser in standalone form. 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.

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.
