npm Taobao mirror modification explanation

npm Taobao mirror modification explanation

1. Top-level usage

1. Install cnpm

npm i -g cnpm --registry=https://registry.npm.taobao.org

2. Then you can install the dependent packages with cnpm

cnpm i -g vue vue-cli

3. Check with cnpm config ls

E:\My Project\2018-08>cnpm config ls
; cli configs
disturl = "https://npm.taobao.org/mirrors/node"
metrics-registry = "https://registry.npm.taobao.org/"
registry = "https://registry.npm.taobao.org/"
scope = ""
user-agent = "npm/6.3.0 node/v8.11.3 win32 x64"
userconfig = "C:\\Users\\Administrator\\.cnpmrc"

; node bin location = D:\Program Files\nodejs\node.exe
; cwd = E:\My Project\2018-08
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.


E:\My Project\2018-08>

You will find that the registry has become a Taobao mirror (warehouse): https://registry.npm.taobao.org/

[The "mirror" in this article is equivalent to the "warehouse", the same below]

2. Original npm

1. View the original configuration npm config ls

E:\My Project\2018-08>npm config ls
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.6.0 node/v8.11.3 win32 x64"

; userconfig C:\Users\Administrator\.npmrc
cache = "D:\\Program Files\\nodejs\\node_cache"
prefix = "D:\\Program Files\\nodejs\\node_global"

; builtin config undefined

; node bin location = D:\Program Files\nodejs\node.exe
; cwd = E:\My Project\2018-08
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.


E:\My Project\2018-08>

You will find that the registry inside is the original image of npm: https://registry.npmjs.org/

2. npm temporarily uses Taobao mirror to install dependent packages

npm i -g express --registry https://registry.npm.taobao.org

3. npm uses Taobao mirror to install dependent packages

npm config set registry https://registry.npm.taobao.org
npm i -g express

Note that this is not recommended, because it completely sets the npm image to the Taobao image. If some of our dependent packages are only available in the npm original image but not in Taobao, it will be a tragedy. So it is best to separate npm and cnpm.

3. Some common settings

1. Check [npm and cnpm are 2 different]

npm config ls
cnpm config ls

2. Settings: mainly set cache and prefix

npm cofig set cache "D:\Program Files\nodejs\node_cache"
npm cofig set prefix "D:\Program Files\nodejs\node_global"

cnpm cofig set cache "D:\Program Files\nodejs\node_cache"
cnpm cofig set prefix "D:\Program Files\nodejs\node_global"

3. Final Result

E:\My Project\2018-08>cnpm config ls
; cli configs
disturl = "https://npm.taobao.org/mirrors/node"
metrics-registry = "https://registry.npm.taobao.org/"
registry = "https://registry.npm.taobao.org/"
scope = ""
user-agent = "npm/6.3.0 node/v8.11.3 win32 x64"
userconfig = "C:\\Users\\Administrator\\.cnpmrc"

; userconfig C:\Users\Administrator\.cnpmrc
cache = "D:\\Program Files\\nodejs\\node_cache"
prefix = "D:\\Program Files\\nodejs\\node_global"

; node bin location = D:\Program Files\nodejs\node.exe
; cwd = E:\My Project\2018-08
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.


E:\My Project\2018-08>npm config ls
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.6.0 node/v8.11.3 win32 x64"

; userconfig C:\Users\Administrator\.npmrc
cache = "D:\\Program Files\\nodejs\\node_cache"
prefix = "D:\\Program Files\\nodejs\\node_global"

; builtin config undefined

; node bin location = D:\Program Files\nodejs\node.exe
; cwd = E:\My Project\2018-08
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.
