require() is for "commonjs" javascript modules run through nodejs. But if I understand correctly, widgetsnbextension is meant to be used client-side from a browser, where "require" doesn't exist in that form. This is why there are like 1000 different "packagers" for javascript to process NPM modules and their dependencies and wrap them with all this extra nonsense.

To get runtime-linking to work in the way that you're thinking, the server (ipywidgets) would also have to know about all of the filesystem paths where these modules exist, and map them to web url paths, and serve them to the client. I don't think this is something that we should try to add to ipywidgets...

I'll try the other tools you mentioned, node-ast-util sounds like it has some potential.
