if you build for the web, no matter what your backend is (python, go, rust, java, c#), your frontend will almost certainly have some js, so likely you need npm.
That's the arbitrary code execution at install time aspect of npm that developers should be extra wary of in this day and age. Saner node package managers like pnpm ignore the build script and you have to explicitly approve it on a case-by-case basis.
That said, you can execute code with build.rs with cargo too. Cargo is just not a build artifact distribution mechanism.
Honestly I’m shocked to see so many people supporting this
That's not remotely true. If there is a standard (which I wouldn't say there is), it's either docker or curl|bash. Nobody is out there using npm to install packages except web devs, this is absolutely ridiculous on Google's part.
What?!? Must not be in any OS I've ever installed.
Now tar, on the other hand, exists even in windows.
It's crazy that people think strict typing is a chore. Says a lot about our society.
