Official docs say it’s for
Packages that are only needed for local development and testing.
Umm, okay. Not 100% clear there. Some articles mention things like ESLint or Jest (k, I’m onboard there) but others mention Babel or WebPack. I get that you don’t need WebPack libraries to be loaded in the browser but how the hell do you bundle up your code without it? When you use npm ci or npm install you’ll get all dependencies but isn’t it good practice (in a CICD environment) to use --omit=dev or --only=prod?
Sure, that’s fine. I think I didn’t word my comment well. What I meant to say was that you only ever do dev installs for frontend apps, so there’s no difference between dev dependencies and regular dependencies. You can split things however you want.
Ah, gotcha! Fully agree with that.
