I wish the Java community (which I'm actually also a part of) would stop rejecting everything that's not "the Java/enterprise way" and be humbled by exploring better alternatives, or alternatives with different tradeoffs for once.
It's also a common practice to use npm ci in all build scripts to never update packages even if they declared a version range in package.json, and package.lock not being able to satisfy package.json won't cause lock to get overwritten.
[0] Yes, that's right. npm doesn't allow to to install incrementally respecting the lockfile. You can install incrementally with npm i and roll the dice, or install from scratch with npm ci to respect the lockfile. Basically the npm authors took the rm -rf node_modules/ workaround and productized it.
If you run npm i against that package.json and package-lock.json, the latter will never be updated, even if the package.json would be happy with newer versions.
If you manually edit your package.json to have different ranges and run npm i and those ranges aren't compatible with your package-lock.json then the latter will be updated with version that are compatible with your package.json. Further runs of npm i will be as with 2 above.
But of course you may think this behavior is a joke, I do not.
How? Why? What's your use-case?
1) For local development, I’m seeking a command I can use after pulling, to safely and quickly install any needed dependencies that have been added by others. Currently I use npm ci but it’s absurdly overkill (and therefore very slow).
2) For CI itself. I cache node_modules/ across builds, which significantly speeds up my builds. Currently I npm i, and check if lockfile changed, and if it did, checkout lockfile and npm ci.
I shouldn’t need to npm ci ever unless my node_modules/ became corrupt for some reason. Because npm ci ALWAYS blows away node_modules/, it’s not a reasonable piece of everyday functionality, it’s just a semantically ambiguous way to rm -rf node_modules/ && npm i -—respect-lockfile (made up flag I wish existed). The obvious explanation is that the npm developers couldn’t figure out how to reliably reconcile node_modules/ with the lockfile, so just gave up and shipped npm ci.
Or if the rm -rf node_modules/ isn’t strictly necessary for npm ci, then give me npm ci —-skip-drop-node-modules, that would be equivalent and fine for my purposes.
btw ci is super fast (caching) unless you have one of those modules that download the whole effing chromium after install (brain dead behavior).
What do you mean ci is super fast? Is it intended to be caching the packages somewhere other than node_modules?
There's been some bugs in the implementation but never had anything in the last few years, other than some people accidentally committing unapplied package.json changes, and built a precommit hook and a server-side check for that in many projects.

Yes: https://docs.npmjs.com/cli/v6/commands/npm-cache#configurati... . If you want a more Java-like (to be more accurate, artifactory-like) experience, you can also opt-in for Verdaccio: https://verdaccio.org/ You can also use the artifactory itself: https://www.jfrog.com/confluence/display/RTF/Npm+Registry
I had more success with verdaccio though.
Quality of the packages has been discussed to death, say about that anything you like, but npm has been rock-solid for me in the last few years. Definitely not a joke IMHO.
