A whitelist-based HTML santizier based on the HTML5-conformant parse5 parser
npm install safe-htmlsafe-html
=========

Santitize HTML using a whitelist of allowed elements and attributes. Parses the HTML using parse5 which uses the HTML5 parsing algorithm (meaning it should parse documents the same way your browser does).
``javascript`
var santitized = safeHtml("Hello World");
// santitized is now "Hello World";
