What would be the best way to Output Code in TextArea for a UI
render in text for controller action and the text is the code string.
The < and > etc can be passed as is in this mode.
Read a HTML Template File (containing JS and CSS references) in Public directory(?) that needs to be substitute some variables that were inputted in a form by the user.
Create HTML on Ruby Side with some XML Builder instead of Reading a File.
And then pass that String to code.
