Enterprise Private npm

In this getting started guide you will get setup with your Enterprise Private npm registry from Nodejitsu as well as learn about some of the best practices for working with package.json files.

1. Configure the npm CLI

Just like the public registry, the npm CLI program is what you'll use to install, publish and otherwise interact with npm modules. Nodejitsu Enterprise private npm has two changes in the configuration to your npm CLI client:

npm config set always-auth true
npm config set strict-ssl false

Why do you need to do these things?

  • Every request requires authentication: This means that users you have not authorized cannot download packages from your private npm. Since this is not the default behavior of the public npm you need to set:
    npm config set always-auth true
  • Don't be strict about SSL: We do not use the same Certificate Authority (CA) as is used by This should be resolved in the next few weeks (before March 2013). In the meantime however, we are using a wildcard certificate (e.g. * which causes spurriour SSL warnings unless you set:
    npm config set strict-ssl false
    This certificate is issued by Comodo and serves

2. Start making requests against your private npm

Requests can be made against your private npm in two ways:

  • Set the registry for all requests: This means that every request will hit your private registry
    npm config set registry
  • Use the --reg flag when necessary: The --reg flag (short for --registry) will allow you to make any request against your private registry:
    npm info your-private-module --reg

We recommend thatyou set the registry for all requeststo avoid any accidental publishes of private modules to the public registry. Since all new publishes go by default to your private npm registry when you needto publish a new public npm package** you can explicitly set the --reg flag:

cd /my/new/public/package
  npm init
  npm publish --reg

PROTIP: Publish modules using publishConfig

The publishConfig in your package.json does the following (from the npm documentation):

This is a set of config values that will be used at publish-time. It's especially handy if you want to set the tag or registry, so that you can ensure that a given package is not tagged with "latest" or published to the global public registry by default.

Any config values can be overridden, but of course only "tag" and "registry" probably matter for the purposes of publishing.

For example:

    "publishConfig": { "registry": "" }

The benefits of using publishConfig is that it avoids accidental publishes to the public registry due to user error. Take for example a developer on your team who has not properly configured their machine by running npm config set registry or using the --reg flag. That command would send your code public. By using the publishConfig property you avoid that because it is part of your application.
