Well but the docs you cited don't match what you stated. You can delete node_modules and reinstall, it will never update the package-lock.json, you will always end up with the exact same versions as before. The package-lock updating happens when you change version numbers in the package.json file, but that is very much expected! So no, running npm install will not pull in new versions randomly.

The internet disagrees. NPM will gladly ignore and update lock files. There may exist a way to actually respect lock files, but the default mode of operation does not work as you would naively expect.

Those stackoverflow posts are ancient and many major npm releases old, so in other words: irrelevant. That blog post is somewhat up to date but also very vague about the circumstances which would update the lockfile. Which certainly isn't that npm install updates dependencies to newer versions within the semver range, because it absolutely does not.

1. This guy clearly doesn't know how NPM works. Don't use `--no-save` regularly or you'll be intentionally desyncing your lockfile from reality.

2&3. NPM 5 had a bug almost a decade ago. They literally link to it in both of those pages. Here[^1] is a developer repeating how I've said its supposed to work.

It would have taken you less work to just try this in a terminal than search for those "citations".
