CLI applications like Vim, cdargs can open a new screen then allow users to draw characters there. I'd like to try making some tools like that with Node and was told that it was called "alternative screen"(?).
I'm familiar with JS. But if there's not a solution, Python maybe(..) OK. Want some code example please :)
Found a modules according to tMC's anwser, trying to figure out...

Vim uses the ncurses library to do drawing. You have already found a Node.JS bindings, so you should have no trouble using this library within your application.
I propose you to read the NCURSES tutorial and attempt to do it in Node.JS.
