UPDATE: It's actually simpler to use npm ci instead of npm install because it installs devDependencies too and is actually more efficient. Hat tip to Lucian 🍻
Ever need to install your devDependencies in a CI environment but the environment wants to install only dependencies? Here's how to fix it:
npm install --include=dev
You can also omit dependencies with the --omit=... flag.
You can use the options dev, optional and peer in both these flags.
Hope that saves you a few minutes, as it did me! 🍻
Hat tip to Ben McCann on the Svelte Discord for pointing me in the right direction!

What are your opinions comparing this method
npm install --only=prodwithnpm ci?I found that
npm ci --only=prodworks as well (see link)You're correct.
npm cialso installs dev dependencies.Adding
--only=prodor--productionwould not installdevDependenciesand just installdependencies.I'll update the article to show both options 👍
It's now recommended to use
--omit=devover--production😆 Good ole Node.js.
