My only pain point, that I solved with a few lines of elisp, was to go to npmjs, to find the repo link for my dependencies. What's in `node_modules` may be compiled to an inscrutable blob and it's rare to find good library docs.
How's it life changing though? You have to know the package name already to do that. And if you're sitting on npmjs looking at the package already, then you're one click away from Github.
Furthermore... I don't host my packages on Github :-) Don't think that even works for mine.
I have had the thought "NPM search sorted by downloads this week is giving me irrelevant packages" - but I'm not sure this tool solves that.
