a library agnostic extensible DOM utility. Nothing else. Bonzo is designed to live in any host library, or simply as a stand-alone tool for the majority of your DOM-related tasks.

It looks like this

  .append('<p>the happs</p>')
    color: 'red',
    'background-color': 'white'

Paired with a Selector Engine

A great way to use Bonzo is with a selector engine (like Qwery for example). You could wrap bonzo up and augment your wrapper to inherit the same methods. That looks like this:

function $(selector) {
  return bonzo(qwery(selector));

This now allows you to write the following code:

$('#content a[rel~="bookmark"]').after('').css('text-decoration', 'none');

Bonzo Extension API

One of the greatest parts about Bonzo is its simplicity to hook into the internal chain to create custom methods. For example you can create a method called color like this:

  color: function (c) {
    return this.css('color', c);

// you can now do the following

The name Bonzo

Bonzo Madrid was a malicious battle school commander of whom eventually is killed by Ender Wiggin. Bonzo represents the DOM, of whom we'd all love to slay.


$ npm install -d
$ make


$ open tests/tests.html

Browser support

  • IE6+
  • Chrome
  • Safari 4+
  • Firefox 3+
  • Opera

Ender integration

Bonzo is a registered npm package and fits in nicely with the Ender framework. If you don't have Ender, you should install now, and never look back, ever. As a side note the query engine host is set for you when you include it with Ender.

$ npm install ender -g

To combine Bonzo to your Ender build, you can add it as such:

$ ender build bonzo[,modb, modc,...]

or, add it to your existing ender package

$ ender add bonzo
