What are the offline cheat sheets for JS, Node, MongoDB, Express?

Question

JavaScript

Such a situation is that I’m leaving for a place where the Internet seems to exist, but it doesn’t seem to exist, but I want to continue self-study in Node, etc., because there will be plenty of time there, and when I return, “study” in college will begin, and she not particularly friendly with self-study :)
Once I saw one application on YouTube that repeats the content of a wonderful site , but, as always, I thought that it would not be useful :)
So, tell me what good offline cheat sheets or textbooks (free) exist technologies: JavaScript, Node.js, MongoDB, Express. .
Preferably in the form: Desktop application, video tutorial, informative site article (for example, a good post from Habr)
