Hi, JS developer here who uses Nix and who liberally makes use of single-responsibility modules.
No, Nix does not need "hours" to build a modern JS project. Something else is going on here. Nix is slow, but not that slow.
(With the limited information provided here, my first guess would be "someone turned off the binary cache because they don't trust prebuilt binaries, and now it recompiles the world from scratch because there are no prebuilt binaries anymore".)
> while much of that build time is attributable to Nix's way of building dependencies
And that part just doesn't make sense to me. I can't see any way in which specifically Nix's way of building dependencies would contribute to this. The compiling of the universe, sure, but then why mention Nix?
Thank you for heavily derailing the productive, technically meaningful conversation I was having. Next time I won't say anything since apparently productive and technically meaningful conversations aren't what this site is for.
Please take your badly-informed language bashing elsewhere.
I actually audit dependencies for a living, and the dependency model that JS uses is far, far preferable for auditability over the "monolithic tightly-coupled framework and a mountain of custom badly-maintained copy-pasted business logic" approach that is widely used elsewhere.
Seriously, piss off. You clearly don't understand the tools you're loudly complaining about, and it's interfering with what was otherwise a productive discussion about Nix and build times.
Please don't break the site guidelines yourself, regardless of how wrong or annoying other comments are or you feel they are. It only makes the thread even worse.
I've responded to the other user elsewhere, but actually your replies were worse than what you were replying to, even if you're right on the fundamentals. "Please take your badly-informed $thing elsewhere" and "Seriously, piss off" are well out of bounds here.
