npm install -omit=dev => NO (and it’s expected).
Localhost by default has NO NODE_ENV defined, so we can assume it’s development is by default: Work use case got me thinking more, so I decided to research very detailed. Yes, I know, that npm ci under the hood is actually npm install (alias npm i), but still both commands give us different behavior.īy default I always use npm ci (as it’s suggested to run on CI) on my CI instances ( Jenkins, CircleCI, Heroku) so it always installed devDependencies for me and I never intended to include or omit. Reading npm documentation, Stackoverflow questions and answers it’s not always clear how it works. But I didn’t know how environmental variable NODE_ENV value (either not set, development or production) actually influences work of npm. I always knew that npm ci designed to run specifically on CI (at least due to the fact that node_modules is being deleted and package-lock.json file recreated). But when I tried different variants, to be sure if it works at all or not I saw no difference. Our pipeline yaml file was configured to run npm command with deprecated flag – npm ci -dev and as turned out for is suggested to use -include=dev. For instructions, see Loading from node_modules Folders in the Node.Recently, I’ve faced with interesting research task at work related to AzureDevOps as a CI platform and NodeJS/npm as targeted resource.
Node.js looks for dependencies in this directory. To deploy dependency packages to environment instances together with your application code, include them in a directory You also have the option to remove the setting, and thenĭeploy the new source bundle.

To avoid needing to create a newĮnvironment, change the Node.js version setting in package.json to a Support the configured Node.js version fails.
