# npm
|
|
|
|
Use the `npm` Chef InSpec audit resource to test if a global NPM package is installed. NPM is the the package manager for [Node.js packages](https://docs.npmjs.com), such as Bower and StatsD.

|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.0.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `npm` resource block declares a package and (optionally) a package version:
|
|
|
|
describe npm('npm_package_name') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
where
|
|
|
|
* `('npm_package_name')` must specify an NPM package, such as `'bower'` or `'statsd'`
|
|
* `be_installed` is a valid matcher for this resource
|
|
|
|
You can also specify additional options:
|
|
|
|
describe npm('npm_package_name', path: '/path/to/project') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
The `path` specifies a folder, that contains a `node_modules` subdirectory. It emulates running `npm` inside the specified folder. This way you can inspect local NPM installations as well as global ones.
|

## Examples

it { should be_installed }
|
|
its('version') { should eq '1.4.1' }
|
|
end
|
|
|
|
### Verify that statsd is not installed
|
|
|
|
describe npm('statsd') do
