uplinks（上行链路）	上行链路

An uplink is a link with an external registry that provides access to external packages.

用法

uplinks:
  npmjs:
   url: https://registry.npmjs.org/
  server2:
    url: http://mirror.local.net/
    timeout: 100ms
  server3:
    url: http://mirror2.local.net:9000/
  baduplink:
    url: http://localhost:55666/

配置

You can define mutiple uplinks and each of them must have an unique name (key). They can have the following properties:

属性	类型	必须的	范例	支持版本	描述	默认值
url	string	是	https://registry.npmjs.org/	全部	外部注册服务器URL	npmjs
ca	string	否	~./ssl/client.crt'	全部	SSL证书文件路径	无默认值
timeout	string	否	100ms	全部	为请求设置新的超时时间	30s
maxage	string	否	10m	全部	the time threshold to the cache is valid	2m
fail_timeout	string	否	10m	全部	请求在连续失败超过指定次数后的最长等待重试时间	5m
max_fails	number	否	2	全部	请求连续失败的最大次数限制	2
cache	boolean	否	[true,false]	>= 2.1	缓存下载的远程tarball文件到本地	true
auth	list	否	见下文	>= 2.5	指定“授权authorization”请求头的内容 详情见	禁用
headers	list	否	authorization: "Bearer SecretJWToken=="	全部	上行链路请求的请求头header列表	禁用
strict_ssl	boolean	否	[true,false]	>= 3.0	为true时，会检测SSL证书的有效性	true
agent_options	object	否	maxSockets: 10	>= 4.0.2	options for the HTTP or HTTPS Agent responsible for managing uplink connection persistence and reuse more info	无默认值

Auth属性

auth 属性内容是向上行链路发起请求时提供的授权令牌。例如使用默认环境变量:

uplinks:
  private:
    url: https://private-registry.domain.com/registry
    auth:
      type: bearer
      token_env: true # defaults to `process.env['NPM_TOKEN']`

或者使用一个指定的环境变量

uplinks:
  private:
    url: https://private-registry.domain.com/registry
    auth:
      type: bearer
      token_env: FOO_TOKEN

token_env: FOO_TOKEN内部将使用 process.env['FOO_TOKEN']

或者直接指定令牌:

uplinks:
  private:
    url: https://private-registry.domain.com/registry
    auth:
      type: bearer
      token: "token"

注意: token的优先级高于token_env

须知

• Uplinks must be registries compatible with the npm endpoints. Eg: verdaccio, sinopia@1.4.0, npmjs registry, yarn registry, JFrog, Nexus and more.
• Setting cache to false will help to save space in your hard drive. This will avoid store tarballs but it will keep metadata in folders.
• Exceed with multiple uplinks might slow down the lookup of your packages due for each request a npm client does, verdaccio does 1 call for each uplink.
• The (timeout, maxage and fail_timeout) format follow the NGINX measurement units
