Package Access

This is a series of constraints that allow or restrict access to the local storage based on specific criteria.

The security constraints remain on the shoulders of the plugin being used, by default verdaccio uses the htpasswd plugin. If you use a different plugin the behaviour might be different. The default plugin does not handle allow_access and allow_publish by itself, it uses an internal fallback in case the plugin is not ready for it.

For more information about permissions visit the authentification section in the wiki.

Usage

packages:
# scoped packages
'@scope/*':
access: $all
publish: $all
proxy: server2

'private-*':
access: $all
publish: $all
proxy: uplink1

'**':
# allow all users (including non-authenticated users) to read and
# publish all packages
access: $all
publish: $all
proxy: uplink2

if none is specified, the default one remains

packages:
'**':
access: $all
publish: $authenticated

The list internal groups handled by verdaccio are:

'$all', '$anonymous', '@all', '@anonymous', 'all', 'undefined', 'anonymous'

All users receive all those set of permissions independently of is anonymous or not plus the groups provided by the plugin, in case of htpasswd return the username as a group. For instance, if you are logged as npmUser the list of groups will be.

// groups without '$' are going to be deprecated eventually
'$all', '$anonymous', '@all', '@anonymous', 'all', 'undefined', 'anonymous', 'npmUser'

If you want to protect specific set packages under your group, you need to do something like this. Let's use a Regex that covers all prefixed npmuser- packages. We recommend using a prefix for your packages, in that way it will be easier to protect them.

packages:
'npmuser-*':
access: npmuser
publish: npmuser

Restart verdaccio and in your console try to install npmuser-core.

$ npm install npmuser-core
npm install npmuser-core
npm ERR! code E403
npm ERR! 403 Forbidden: npmuser-core@latest

npm ERR! A complete log of this run can be found in:
npm ERR! /Users/user/.npm/_logs/2017-07-02T12_20_14_834Z-debug.log

You can change the existing behaviour using a different plugin authentication. verdaccio just checks whether the user that tried to access or publish a specific package belongs to the right group.

Please note that if you set the access permission of a package to something that requires Verdaccio to check your identity, for example $authenticated, npm does not send your access key by default when fetching packages. This means all requests for downloading packages will be rejected as they are made anonymously even if you have logged in. To make npm include you access key with all requests, you should set the always-auth npm setting to true on any client machines. This can be accomplished by running:

$ npm config set always-auth=true

Set multiple groups

Defining multiple access groups is fairly easy, just define them with a white space between them.

  'company-*':
access: admin internal
publish: admin
proxy: server1
'supersecret-*':
access: secret super-secret-area ultra-secret-area
publish: secret ultra-secret-area
proxy: server1

Blocking access to set of packages

If you want to block the access/publish to a specific group of packages. Just do not define access and publish.

packages:
'old-*':
'**':
access: $all
publish: $authenticated

Blocking proxying a set of specific packages

You might want to block one or several packages from fetching from remote repositories., but, at the same time, allow others to access different uplinks.

Let's see the following example:

packages:
'jquery':
access: $all
publish: $all
'my-company-*':
access: $all
publish: $authenticated
'@my-local-scope/*':
access: $all
publish: $authenticated
'**':
access: $all
publish: $authenticated
proxy: npmjs

Let's describe what we want with the above example:

  • I want to host my own jquery dependency but I need to avoid proxying it.
  • I want all dependencies that match with my-company-* but I need to avoid proxying them.
  • I want all dependencies that are in the my-local-scope scope but I need to avoid proxying them.
  • I want proxying for all the rest of the dependencies.

Be aware that the order of your packages definitions is important and always use double wilcard. Because if you do not include it verdaccio will include it for you and the way that your dependencies are resolved will be affected.

You may assign multiple uplinks for use as a proxy to use in the case of failover, or where there may be other private registries in use.

'**':
access: $all
publish: $authenticated
proxy: npmjs uplink2

Unpublishing Packages

The property publish handle permissions for npm publish and npm unpublish. But, if you want to be more specific, you can use the property unpublish in your package access section, for instance:

packages:
'jquery':
access: $all
publish: $all
unpublish: root
'my-company-*':
access: $all
publish: $authenticated
unpublish:
'@my-local-scope/*':
access: $all
publish: $authenticated
# unpublish: property commented out
'**':
access: $all
publish: $authenticated
proxy: npmjs

In the previous example, the behaviour would be described:

  • all users can publish the jquery package, but only the user root would be able to unpublish any version.
  • only authenticated users can publish my-company-* packages, but nobody would be allowed to unpublish them.
  • If unpublish is commented out, the access will be granted or denied by the publish definition.

Configuration

You can define mutiple packages and each of them must have an unique Regex. The syntax is based on minimatch glob expressions.

PropertyTypeRequiredExampleSupportDescription
accessstringNo$allalldefine groups allowed to access the package
publishstringNo$authenticatedalldefine groups allowed to publish
proxystringNonpmjsalllimit look ups for specific uplink
storagestringNostring/some-folderit creates a subfolder whithin the storage folder for each package access

We higlight that we recommend to not use allow_access/allow_publish and proxy_access anymore, those are deprecated and will soon be removed, please use the short version of each of those (access/publish/proxy).
