HTML parser 

- jsdom
  It's an npm library that can take html as input and let you do things like document.querySelector on it inside of NodeJS without running a sandboxed browser instance
- node-html-parser : like jsdom
  https://www.npmjs.com/package/node-html-parser
  eg
  ```js
	import { parse } from 'node-html-parser';

	const root = parse('<ul id="list"><li>Hello World</li></ul>');

	console.log(root.firstChild.structure);
	// ul#list
	//   li
	//     #text

	console.log(root.querySelector('#list'));
	// { tagName: 'ul',
	//   rawAttrs: 'id="list"',
	//   childNodes:
	//    [ { tagName: 'li',
	//        rawAttrs: '',
	//        childNodes: [Object],
	//        classNames: [] } ],
	//   id: 'list',
	//   classNames: [] }
	console.log(root.toString());
	// <ul id="list"><li>Hello World</li></ul>
	root.set_content('<li>Hello World</li>');
	root.toString();	// <li>Hello World</li>
	```
