Thanks for the link. However, a 7x size differential does not fully explain a 100x security incident differential -- although I'm sure it's part of it. Some of the root causes are very hard to address (e.g. a very limited standard library which encourages dependency explosions), some are just hard (e.g. established cultural norms around version pinning and upgrades, well-established reliance on install scripts) and some are easier (e.g. small tool improvements like min-release-age). I'm personally not going to touch npm with a ten foot pole in the next year or two, but I'd love to see significant improvement, so that I have that option again in 2 or 3 years. Stay safe!
The npm cli has bad defaults which you can turn off but they are there I presume for legacy reasons. The secure option is pnpm. The registry is fine.
Also on our comment about size differential ... it absolutely can.
If I jump from 2 meters hight it will be mildly uncomfortable. Jumping from 12 meters will result in severe injurious and possibly death. None of these things go linearly in real world conditions.
