npm/yarn查看当前使用源与设置其它源

1.前言

npm,yarn查看源和换国内源，毕竟国外的资源下载，在国内速度是非常慢的。cgr（change registry | yarn & npm registry manager）是一款能同时、分开管理npm、yarn源的工具工具更好管理 

2.内容
2.1 npm, yarn查看源和换源：

npm config get registry  // 查看npm当前镜像源

npm config set registry https://registry.npmjs.org

yarn config get registry  // 查看yarn当前镜像源

yarn config set registry https://registry.yarnpkg.com 

镜像源地址部分如下：

npm --- https://registry.npmjs.org/

npm --- https://registry.npm.taobao.org/

yarn --- https://registry.yarnpkg.com/

yarn --- https://registry.npm.taobao.org/

cnpm --- https://r.cnpmjs.org/

taobao --- https://registry.npm.taobao.org/

nj --- https://registry.nodejitsu.com/

rednpm --- https://registry.mirror.cqupt.edu.cn/

npmMirror --- https://skimdb.npmjs.com/registry/

deunpm --- http://registry.enpmjs.org/

2.2 cgr一款能同时、分开管理npm、yarn源的工具 

2.2.1 安装

• npm: https://www.npmjs.com/package/cgr
• github: https://github.com/daysai/cgr

npm install -g cgr

2.2.2 默认源列表

cgr ls

N npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
Y taobao - https://registry.npm.taobao.org/
  yarn --- https://registry.yarnpkg.com/

N代表npm，Y代表yarn，*代表npm和yarn共用的源

2.2.3源切换

cgr use cnpm
npm registry has been set to: http://r.cnpmjs.org/
yarn registry has been set to: http://r.cnpmjs.org/

cgr use cnpm y
yarn registry has been set to: http://r.cnpmjs.org/

cgr use cnpm n
npm registry has been set to: http://r.cnpmjs.org/

y/yarn代表yarn切换，n/npm代表npm切换，大小写均可；type为空，表示同时切换源

2.2.4添加私有源

cgr add test http://registry.private.com
add registry test success

cgr ls
N npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
Y taobao - https://registry.npm.taobao.org/
  yarn --- https://registry.yarnpkg.com/
  test --- http://registry.private.com/

2.2.5删除私有源 

cgr del test
delete registry test success

2.2.6源响应时间测试

cgr test

N npm ---- 693ms
  cnpm --- 223ms
Y taobao - 102ms
  yarn --- 929ms

说明：cgr 是基于nrm的改进版本，进行了一些优化，能同时管理npm、yarn源。底层通过bash命令进行源切换操作，避免了直接操作.yarnrc等源管理文件。
