node : npm / nrm（npm registry manager ） : 切换源

Posted 2021-06-24 Mars-xq

一、npm传统设置

设置：

以前都是这样切换taobao源：

# 淘宝
npm config set registry https://registry.npm.taobao.org --global
yarn config set registry http://registry.npm.taobao.org/ --global
# 官网
npm config set registry https://registry.npmjs.org/ --global

查看

> npm config get registry  
https://registry.npm.taobao.org/

或

> npm config list
; cli configs
metrics-registry = "https://registry.npm.taobao.org/"
scope = ""
user-agent = "yarn/1.15.2 npm/? node/v14.2.0 darwin x64"

; environment configs
bin-links = true
disturl = "https://npm.taobao.org/dist"
init-license = "MIT"
init-version = "1.0.0"
registry = "https://registry.npm.taobao.org/"
save-prefix = "^"
strict-ssl = true
user-agent = "yarn/1.15.2 npm/? node/v14.2.0 darwin x64"
version-commit-hooks = true
version-git-message = "v%s"
version-git-tag = true
version-tag-prefix = "v"

; userconfig /Users/tmk/.npmrc
home = "https://www.npmjs.org"

; globalconfig /Users/tmk/.nvm/versions/node/v14.2.0/etc/npmrc

; node bin location = /Users/tmk/.nvm/versions/node/v14.2.0/bin/node
; cwd = /Users/tmk
; HOME = /Users/tmk
; "npm config ls -l" to show all defaults.

或

> npm info express

二、nrm设置（推荐）

nrm(npm registry manager)是npm的镜像源管理工具，有时候国外资源太慢，
使用这个就可以快速地在 npm 源间切换

安装 nrm

npm install -g nrm

查看帮助

> nrm -h
Usage: nrm [options] [command]

Options:
  -V, --version                           output the version number
  -h, --help                              output usage information

Commands:
  ls                                      List all the registries
  current                                 Show current registry name
  use <registry>                          Change registry to registry
  add <registry> <url> [home]             Add one custom registry
  set-auth [options] <registry> [value]   Set authorize information for a custom registry with a base64 encoded string or username and pasword
  set-email <registry> <value>            Set email for a custom registry
  set-hosted-repo <registry> <value>      Set hosted npm repository for a custom registry to publish packages
  del <registry>                          Delete one custom registry
  home <registry> [browser]               Open the homepage of registry with optional browser
  publish [options] [<tarball>|<folder>]  Publish package to current registry if current registry is a custom registry.
   if you're not using custom registry, this command will run npm publish directly
  test [registry]                         Show response time for specific or all registries
  help                                    Print this help

查看镜像源列表

> nrm ls

  npm -------- https://registry.npmjs.org/
  yarn ------- https://registry.yarnpkg.com/
  cnpm ------- http://r.cnpmjs.org/
* taobao ----- https://registry.npm.taobao.org/
  nj --------- https://registry.nodejitsu.com/
  npmMirror -- https://skimdb.npmjs.com/registry/
  edunpm ----- http://registry.enpmjs.org/

其中，带*的是当前使用的源，上面的输出表明当前源是taobao源。

直接查看当前源

> nrm current
taobao

或

> npm config get registry
https://registry.npm.taobao.org/

切换到淘宝镜像源

> nrm use taobao

测试相应源的响应时间

> nrm test npm                                                                                                                             
> nrm test taobao
