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 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。
