开发的npm registry 管理工具 nrm, 能够查看和切换当前使用的registry, 最近NPM经常 down 掉, 这个还是很有用的哈哈

Install

$ npm install -g nrm

Example

$ nrm ls

* npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
  eu ----- http://registry.npmjs.eu/
  au ----- http://registry.npmjs.org.au/
  sl ----- http://npm.strongloop.com/
  nj ----- https://registry.nodejitsu.com/
$ nrm use cnpm //switch registry to cnpm

    Registry has been set to: http://r.cnpmjs.org/

cmd

nrm help // show help
nrm list // show all registries
nrm use cnpm // switch to cnpm
nrm home // go to a registry home page
