As usual, there's a cultural issue here. I know it's entirely possible to paste those seven lines of code into your app. And in many development cultures this will be considered a good thing.

If you're working with Javascript people, this is referred to as "reinventing the wheel" or "rolling your own", or any variation of "this is against best practice".

I think the fact that everyone cites the same is-number package when saying this is indicative of something though.

Like I legit think that we are all imagining this cultural problem that's widespread. My claim (and I tried to do some graph theory stuff on this in the past and gave up) is that in fact we are seeing something downstream of a few "bad actors" who are going way too deep on this.

I also dislike things like webpack making every plugin an external dep but at least I vaguely understand that.

Have you heard of the left pad incident?

The problem is not imagined.

Even there the "problem" was left-pad being used by one or two projects used in "everything".

So the problem isn't that everyone is picking up small deps, but that _some_ people who write libs that are very popular are picking up small deps and causing this to happen.

This is different because it doesn't really say that all JS developers are looking to include left-pad. But I _do_ think that lots of library authors are too excited to make these kinds of dep trees

The point isn't that everyone needs to write the same code manually necessarily. It's that an author could easily just combine the entire tree of seven line packages into the one package the create-react-app uses directly. There's no reason to have a dozen or so package downloads each with seven lines of code instead of one that that's still under under a hundred lines; that's still a pretty small network request, and it's not like dead code analysis to prune unused functions isn't a thing. If you somehow find yourself in a scenario where you would be happy to download seven lines of code, but downloading a few dozen more would be an issue, that's when you might want to consider pasting the seven lines of code manually, but I honestly can't imagine when that would be.

The problem I think is that the js community somehow thinks that being on npm is some bastion of good quality.

Just as the cloud is simply someone else's computer, a package is just someone else's reinvented wheel.

The problem is half the wheels on npm are fucking square and apparently no one in the cult of JavaScript realises it.
