npm-registry-client

The code that npm uses to talk to the registry.

It handles all the caching and HTTP calls.

Usage

var RegClient = require('npm-registry-client')
var client = new RegClient(config)

client.get("npm", "latest", 1000, function (er, data, raw, res) {
  // error is an error if there was a problem.
  // data is the parsed data object
  // raw is the json string
  // res is the response from couch
})
