uplinks	Uplinks

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

Usage

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/

Configuration

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

Property	Type	Required	Example	Support	Description	Default
url	string	Yes	https://registry.npmjs.org/	all	The registry url	npmjs
ca	string	No	~./ssl/client.crt'	all	SSL path certificate	No default
timeout	string	No	100ms	all	set new timeout for the request	30s
maxage	string	No	10m	all	limit maximun failure request	2m
fail_timeout	string	No	10m	all	defines max time when a request becomes a failure	5m
max_fails	number	No	2	all	limit maximun failure request	2
cache	boolean	No	[true,false]	>= 2.1	cache all remote tarballs in storage	true
auth	list	No	see below	>= 2.5	assigns the header 'Authorization' more info	disabled
headers	list	No	authorization: "Bearer SecretJWToken=="	all	list of custom headers for the uplink	disabled
strict_ssl	boolean	No	[true,false]	>= 3.0	If true, requires SSL certificates be valid.	true

Auth property

The auth property allows you to use an auth token with an uplink. Using the default environment variable:

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

or via a specified environment variable:

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

token_env: FOO_TOKENinternally will use process.env['FOO_TOKEN']

or by directly specifying a token:

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

Note: token has priority over token_env

You Must know

• Verdaccio does not use Basic Authentication since version v2.3.0. All tokens generated by verdaccio are based on JWT (JSON Web Token)
• 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
