The article in question has a single external reference: a page on the CommonJS wiki which basically just says that NodeJS exists. Add some real citations to the article and the issue goes away.
Also, notice the sentences "You may remove this message if you improve the article or otherwise object to deletion for any reason" and "If this template is removed, it should not be replaced." in the original warning.
