    Use GitLab Community Edition as authentication provider for the private npm registry Verdaccio, the sinopia fork.

    npm build dependencies

    The main goal and differences from other sinopia/verdaccio plugins are the following:

    • no admin token required
    • user authenticates with Personal Access Token
    • access & publish packages depending on user rights in gitlab

    This is experimental!

    Use it

    You need at least node version 8.x.x, codename carbon.

    git clone
    cd verdaccio-gitlab
    yarn install
    yarn start

    NOTE: Define http_proxy environment variable if you are behind a proxy.

    Verdaccio is now up and running. In order the see this plugin in action, you can use the following Verdaccio configuration in your ~/.config/verdaccio/config.yaml.

    # Verdaccio storage location relative to $HOME/.config/verdaccio 
    storage: ./storage
        # scoped packages 
        access: $all
        publish: $authenticated
        proxy: npmjs
        gitlab: true
        access: $all
        publish: $authenticated
        proxy: npmjs
        gitlab: true
    # Log level can be changed to info, http etc. for less verbose output 
      {type: stdout, format: pretty, level: debug}

    Restart Verdaccio and authenticate into it with your credentials

    using the Web UI http://localhost:4873 or via npm CLI:

    yarn login --registry http://localhost:4873

    and publish packages:

    yarn publish --registry http://localhost:4873

    Access Levels

    Access and publish access rights are mapped following the rules below.

    verdaccio-gitlab access control will only be applied to package sections that are marked with gitlab: true as in the configuration sample above. If you wish to disable gitlab authentication to any package config, just remove the element from the config.


    access is allowed depending on the following verdaccio package configuration directives:

    • authenticated users are able to access all packages
    • unauthenticated users will be able to access packages marked with either $all or $anonymous access levels at the package group definition

    Please note that no group or package name mapping is applied on access, any user successfully authenticated can access all packages.


    publish is allowed if:

    1. the package name matches the GitLab username, or
    2. if the package name or scope of the package matches one of the user's GitLab groups, or
    3. if the package name (possibly scoped) matches on the user's GitLab projects.

    For 2. and 3., the GitLab user must have the access rights on the group or project as specified in the auth.gitlab.publish setting.

    For instance, assuming the following configuration:

        publish = $maintainer

    The GitLab user sample_user has access to:

    • Group group1 as $maintainer
    • Group group2 as $reporter
    • Project group3/project as $maintainer

    Then this user would be able to:

    • access any package
    • publish any of the following packages:
      • sample_user
      • group1
      • any package under @group1/**
      • @group3/project

    There would be an error if the user tried to publish any package under @group2/**.

    Configuration Options

    The full set of configuration options is:

        url: <url>
          enabled: <boolean>
          ttl: <integer>
        publish: <string>
    Option Default Type Description
    url <empty> url mandatory, the url of the gitlab server
    authCache: enabled true boolean activate in-memory authentication cache
    authCache: ttl 300 (0=unlimited) integer time-to-live of entries in the authentication cache, in seconds
    publish $maintainer [$guest, $reporter, $developer, $maintainer, $owner] group minimum access level of the logged in user required for npm publish operations

    Authentication Cache

    In order to avoid too many authentication requests to the underlying gitlab instance, the plugin provides an in-memory cache that will save the detected groups of the users for a configurable ttl in seconds.

    No clear-text password is saved in-memory, just an SHA-256 hash of the user+password, plus the groups information.

    By default, the cache will be enabled and the credentials will be stored for 300 seconds. The ttl is checked on access, but there's also an internal timer that will check expired values regularly, so data of users not actively interacting with the system will also be eventually invalidated.

    Please note that this implementation is in-memory and not multi-process; if the cluster module is used for starting several verdaccio processes, each process will store its own copy of the cache, so each user will actually be logged in multiple times.


    git clone
    cd verdaccio-gitlab
    docker-compose up --build -d

    The Dockerfile provides a default configuration file that is internally available under /verdaccio/conf/config.yaml. In order to overwrite this configuration you can provide your own file and mount it on docker startup with the --volume option, or equivalent mechanism (e.g. ConfigMaps on Kubernetes / OpenShift with the helm chart).

    Create a Release

    Run one of the following command to create a release:

    yarn release:major
    yarn release:minor
    yarn release:patch

    finally run

    yarn publish

    Flow Support

    In order to support flow, flow-typed support files are installed in the repo. These are generated based on the dependencies of the project and committed to the repository.

    Anytime the project dependencies change, run the following command to update the flow-typed support files:

    # Just once in your environment 
    yarn global add flow-typed
    flow-typed install

    Functional Tests

    In order to run functional tests with debug output, set the VERDACCIO_DEBUG=true environment variable, as documented by verdaccio:

    VERDACCIO_DEBUG=true yarn test:functional
