Recently, I have had to analyse and upgrade a web application.
I need to know the relationships and functions of each file including CSS and JS inside each page, as opposed to the whole website.
Thus, I would like to draw a "file map" to visually understand and easily track the file relationships.
What is the the best/recommended methodology to analyse and visualize the relationships including JS, CSS and so on?
(I am not sure what to call this feature, so I have used "file map" at the moment)
