To resolve packages by name and version, npm talks to a registry website that implements the CommonJS Package Registry specification for reading package info.
Additionally, npm's package registry implementation supports several write APIs as well, to allow for publishing packages and managing user account information.
The official public npm registry is at http://registry.npmjs.org/. It is powered by a CouchDB database, of which there is a public mirror at http://skimdb.npmjs.com/registry. The code for the couchapp is available at http://github.com/npm/npm-registry-couchapp.
The registry URL used is determined by the scope of the package (see
npm-scope(7)). If no scope is specified, the default registry is used, which is
supplied by the
registry config parameter. See
npm-config(7) for more on managing npm's configuration.
The easiest way is to replicate the couch database, and use the same (or similar) design doc to implement the APIs.
If you set up continuous replication from the official CouchDB, and then
set your internal CouchDB as the registry config, then you'll be able
to read any published packages, in addition to your private ones, and by
default will only publish internally. If you then want to publish a
package for the whole world to see, you can simply override the
--registry config for that command.
"private": true in your package.json to prevent it from being
published at all, or
to force it to be published only to your internal registry.
package.json(5) for more info on what goes in the package.json file.
No. If you want things to be public, then publish them into the public registry using npm. What little security there is would be for nought otherwise.
No, but it's way easier. Basically, yes, you do, or you have to effectively implement the entire CouchDB API anyway.
Yes, head over to https://npmjs.com/
