Automated HTML Validation with Node.js and Valimate
Happy new year!
As a standards nut, I often endorse serving valid HTML. After having implemented an automated solution at work, which HTTP GETs our web app's HTML and sends it to the Nu HTML Checker, I released Valimate; it's a command line interface developed in Node.js that validates a configured list of URLs.
You can read about it, and the motivations behind it, in an article that I recently published on Medium.
