 DOMPurify technically also works server-side with Node.js. Our support strives to follow the [Node.js release cycle](https://nodejs.org/en/about/releases/).
 
-Running DOMPurify on the server requires a DOM to be present, which is probably no surprise. Usually, [jsdom](https://github.com/jsdom/jsdom) is the tool of choice and we **strongly recommend** to use the latest version of _jsdom_.

 Why? Because older versions of _jsdom_ are known to be buggy in ways that result in XSS _even if_ DOMPurify does everything 100% correctly. There are **known attack vectors** in, e.g. _jsdom v19.0.0_ that are fixed in _jsdom v20.0.0_ - and we really recommend to keep _jsdom_ up to date because of that.
