Preserves the presence or lack thereof of whitespace surrounding HTML comments.
HTML formatters don't always properly handle HTML comments. This package attempts to properly maintain the whitespace around the HTML comments.
Some known issues:
$ npm install preserve-comment-whitespace
const { preserve, restore } = require('preserve-comment-whitespace');
const beautify = require('js-beautify').html;
const html = `<div><div><!-- my html comment --></div></div>`
const comments = preserve(html);
const formatted = beautify(html);
//=> <div>\n <div>\n <!-- my html comment -->\n </div>\n</div>
const formattedAndRestored = restore(formatted, comments)
//=> <div>\n <div><!-- my html comment --></div>\n</div>
Returns an Array containing the objects descripting the HTML comments.
Returns a string where the whitespace around the HTML comments is restored.
Note: the processing between preserve

should add or remove any comments. If the number of comments given don't match the number of comments found in the given HTML, restore
will return the given string, unprocessed.
