Based on [npm-delegate] (https://npmjs.org/package/npm-delegate) by Jason Denizac [email protected], this module is a hapi plugin used to proxy npm to support private npm repos without replicating the entire public registry.

NOTE: The config.json described below is a Hapi Composer manifest that describes kappa as a plugin. See ./example/global/config.json or ./example/local/config.json for more information.

$ npm install -g kappa
$ kappa -c config.json

If you choose to install locally, running kappa is as easy as

$ npm init
$ npm install --save kappa

# add start script to package.json:
#    "scripts": {
#        "start": "kappa -c config.json",
#    }

$ npm start

You can then put those artifacts (config.json and package.json) under source control for simple deployments later:

$ git clone [email protected]:me/myregistry.git
$ cd myregistry
$ npm install
$ npm start

kappa plugin currently supports the following parameters

• vhost - the virtual host associated with the kappa server, e.g. 'npm.mydomain.com'
• paths (optional) - any ordered array of npm repositories to use, e.g. Defaults to ['http://localhost:5984/registry/_design/app/_rewrite/', 'https://registry.npmjs.org/']

For read operations (GET, HEAD, etc) the proxy will first attempt to fetch the module from the first registry. If the requested module is not found it continues to the next registry, and so on.

For write operations the proxy will only attempt to write to the FIRST registry. All auth occurs with the first registry as well.
