What you are looking for is called "Program Understanding". If you Google for it you'll find a bunch of research papers on the topic. For some reason, tools related to program understanding are not widely adopted by IDEs. A while ago I used a tool for Java that was based on the Object-Oriented Metrics[0] book by Michele Lanza. But, that tool was discontinued and it doesn't exist anymore[1]. If you are interested in that topic take a look at Moose[2], a dig a little bit in the research papers. (honestly I tried Moose a few times, but I wasn't very comfortable with it). For TypeScript projects, the TS compiler API is extremely powerful and easy to use. You can use that to extract information and analyze the code relationships (Graphviz is your friend here :) ).
