Are the Node Module Dependencies automatically installed?

I have installed a PDFkit node module to use in some backend code to generate some pdfs. Using the package manager I added it to my site but it does not appear to be functioning properly and so I was wondering if all the dependencies were automatically installed. It doesn’t make sense why the dependencies would not be installed but I do not see them independently listed in the package manager either.
Thanks in advance.

From my experience, dependencies are also installed. It’s probably not working for other reasons. You should check the author’s documentation for further details.

Ok thank you. I will look more into that. I am glad to know everything should be installed then.
