# Set the repository for the scope "myscope"
npm config set @myscope:registry <http://registry.corporation.com>

# Login at a repository and associate it with the scope "myscope"
npm adduser --registry=http://registry.corporation.com --scope=@myscope

# Install a package "mylib" from the scope "myscope"
npm install @myscope/mylib

If the name of your own package starts with @myscope and the scope “myscope” is associated with a different repository, npm publish will upload your package to that repository instead.

You can also persist these settings in a .npmrc file:

@myscope:registry=http://registry.corporation.com
//registry.corporation.com/:_authToken=xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxxxxx

This is useful when automating the build on a CI server f.e.
