How do you get the textarea, or any other element, into a canvas?

I don't. The textarea remains hidden (off screen) in the background. It has the user's focus, so when the user types, it's receiving keystrokes as usual. Simultaneously, the render loop simply reads the text and selection state (selectionStart, selectionEnd) from the text area and renders the textarea's text and selection cursor/selection-highlight onto a canvas.

Same approach here. Except that I use the ace editor (http://ace.c9.io/) as the backend. This has the nice advantage that you get full code editing capabilities in 3D.
