npm ci vs npm install

Starting MARCH 5, 2018, all npm users can take advantage of a new install command called npm ci.

npm install :- install new dependencies, or update existing dependencies (e.g. going from version 1 to version 2).

npm ci :- when you want to run continuous integration tools like Jenkins or GitLab, etc., it doesn't modify the package-lock.json file. It’s meant to be used in automated environments such as test platforms, continuous integration, and deployment – or any situation where you want to make sure you’re doing a clean install of your dependencies.

Essentially, npm install reads package.json to create a list of dependencies and uses package-lock.json to inform which versions of these dependencies to install.
