According to the validator.js documentation, XSS sanitization was removed from the library in late 2013. Because of this, I believe it makes sense to remove it as a suggestion from the SSR recipe. At the time, the maintainer suggested checking out Google Caja. I also did some searching on NPM and found the following two packages, both of which seem full featured and popular:
https://www.npmjs.com/package/xss
https://www.npmjs.com/package/xss-filters
Should we replace the suggestion with one of the alternatives above? Definitely open to suggestions — thanks!
