Working with private modules

With npm private modules, you can use the npm registry to host your own private code and the npm command line to manage it. This makes it easy to use public modules like Express and Browserify side-by-side with your own private code.

You need a version of npm greater than 2.7.0, and you'll need to log in to npm again.

sudo npm install -g npm
npm login

All private packages are scoped.

Scopes are a new feature of npm. If a package's name begins with @, then it is a scoped package. The scope is everything in between the @ and the slash.

@scope/project-name

When you sign up for private modules as an individual user, your scope is your username.

@username/project-name

If you use npm init to initialize your packages, you can pass in your scope like this:

npm init --scope=<your_scope>

If you use the same scope most of the time, you'll probably want to set it in your default configuration instead.

npm config set scope <your_scope>

Publishing your package is easy.

npm publish

By default, scoped packages are published as private. You can read more about this in the scopes documentation.

Once it's published, you should see it on the website with a private flag.

If you want to give access to someone, they need to be subscribed to private modules as well. Once they are, you can give them read or read-write access.

You can control access to the package on the access page. To get to the page, click on the Collaborators link or the plus button.

Add collaborators by entering the username and hitting enter.

You can also add collaborators on the command line:

npm owner add <user> <package name>

To install a private module, you must have access to the package. Then you can use install with the scoped package name.

npm install @scope/project-name

You also use the scoped package name when requiring it.

var project = require('@scope/project-name')

All scoped packages default to private. This ensures that you don't make something public by accident. You can change this on the access page.

You can also manage package access via the command line:

npm access restricted <package_name>

The package will be removed from listings on the site within a few minutes of making it private.
