I don't know much about NPM (having avoided JS as much as possible for my entire life), but golang seems to have a good solution: 'vendoring'. One can choose to lock all external dependencies to local snapshots brought into a project, with no automatic updating, but with the option to manually update them when desired.
Ah, good. I wonder why it isn't used more often -- this wouldn't be such a huge problem then I would hope. (Let me guess -- 'convenience', the archenemy of security.)
That won't prevent typo squatting. This article is a out people wanting to add a dependency to "famousLib" and instead typing "famusLib".
What probably help more in Go is the lack of a central repo so you actually need to "go get github.com/whoever..." so typo squatting is a bit be a bit more complicated.
On the other hand it will be an easy fix in NPM by simply adding a check to libraries names and reject names that are too similar since it's centralized.
