Server-side DOM implementation based on Mozilla's dom.js

Server-side DOM implementation based on Mozilla's dom.js

As the name might suggest, domino's goal is to provide a DOM in Node.

In contrast to the original dom.js project, domino was not designed to run untrusted code. Hence it doesn't have to hide its internals behind a proxy facade which makes the code not only simpler, but also more performant.

Domino currently doesn't use any harmony features like proxies or WeakMaps and therefore also runs in older Node versions.

Speed over Compliance

Domino is intended for building pages rather than scraping them. Hence Domino doesn't execute scripts nor does it download external resources.

Also Domino doesn't implement any properties which have been deprecated in HTML5.

Domino sticks to the DOM level 4 working draft, which means that Attributes do not inherit the Node interface. Also Element.attributes returns a read-only array instead of a NamedNodeMap.

Note that because domino does not use proxies, Element.attributes is not a true JavaScript array; it is an object with a length property and an item(n) accessor method. See github issue #27 for further discussion.

CSS Selector Support

Domino provides support for querySelector(), querySelectorAll(), and matches() backed by the Zest selector engine.

Usage

var domino = require('domino');

var window = domino.createWindow('<h1>Hello world</h1>');
var document = window.document;

var h1 = document.querySelector('h1');
console.log(h1.innerHTML);

Tests

Domino includes test from the W3C DOM Conformance Suites as well as tests from HTML Working Group.

The tests can be run via npm test or directly though the Mocha command line:
