`npm` — NPM packages

The npm check examines the local NPM package database, and inserts that global packages are installed or missing.

It checks global packages, rather than packages specific to a particular package.json.

Examples

Check that a package is installed:

[[npm]]
package = 'yarn'

Check that a particular version is installed:

[[npm]]
package = 'typescript'
version = '3.6.4'

Check that a package is not installed:

[[npm]]
package = 'express'
state = 'missing'

parameter	structure	description
package	string	Name of the package.
state	string	State of the package. This can be `'present'` or `'missing'`.
version	string	If installed, the version that should be present.
