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!
