You don't; you import 3-4 libraries that do what you need, each of them imports 10-30 libraries they need, next thing you know, you've got 100 dependencies.
I don't really see the big deal--for as long as I've been using Linux, which is over 20 years now, installing many packages requires pulling in dozens of other packages, themselves perhaps composed of multiple libraries... The problem is they come from cargo and not a distro? I get the problem with the language repos being more prone to supply chain attack than distro repos, but i don't really get the impression it was ever normal to build complete apps without dependencies.
