Classical dom injection

You can simply download the compiled version as zip file here and inject it after needed dependencies:


<script src=""></script>
<script src=""></script>
<script src=""></script>
<script src=""></script>
<script src=""></script>
<!--Inject downloaded file:-->
<script src="index.compiled.js"></script>
<!--Or integrate via cdn:
<script src=""></script>

The compiled bundle supports AMD, commonjs, commonjs2 and variable injection into given context (UMD) as export format: You can use a module bundler if you want.

Package managed and module bundled

If you are using npm as package manager you can simply add this tool to your package.json as dependency:


"dependencies": {
    "website-utilities": "latest",

After updating your packages you can simply depend on this script and let a module bundler do the hard stuff or access it via an exported variable name in given context.


$ = require('website-utilities')
$.Website().isEquivalentDom('<div>', '<script>') // false

import Website from 'website-utilities'
class SpecialWebsite extends Website...
// or
import {$} from 'website-utilities'
$.Website().isEquivalentDom('<div>', '<script>') // false
class SpecialWebsite extends $.Website.class ...
// or
Website = require('website-utilities').default
value instanceof Website
// or
$ = require('website-utilities').$
