title: How to exclude certain domains from an npm proxy
body: <p>We use npm behind a company firewall and thus use proxy and https-proxy settings in the npm configuration. This works fine as long as all npm modules are loaded from an external registry. But as a matter of fact we also have internal modules on an internal github. The access to these modules must not use the proxy of course. My question is: Can I specify a list of domains in the npm configuration, for which the proxy should not be used? Something like the no_proxy environment variable in the unix shell?</p>
