	# From https://docs.npmjs.com/cli/v7/commands/npm-install

	# The --package-lock-only argument will only update the
	# package-lock.json, instead of checking node_modules and
	# downloading dependencies.
	#
	npm install --package-lock-only --ignore-scripts --include=optional

	# If the package.json (dependencies and devDependencies) is
	# in correct sync with package-lock.json running the above command
	# should not make an edit to the package-lock.json. I.e.
	# running `git status` should
	# say "nothing to commit, working tree clean".
	git diff --exit-code
