# npm
Use the `npm` 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.
<br>
## 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.
<br>
## Examples
The following examples show how to use this InSpec audit resource.
### Verify that bower is installed, with a specific version
describe npm('bower') do
it { should be_installed }
its('version') { should eq '1.4.1' }
end
### Verify that statsd is not installed
describe npm('statsd') do
it { should_not be_installed }
end
<br>
## Matchers
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
### be_installed
The `be_installed` matcher tests if the named Gem package and package version (if specified) is installed:
it { should be_installed }
### version
The `version` matcher tests if the named package version is on the system:
its('version') { should eq '1.2.3' }
