GitLab NPM Registry

• Introduced in GitLab Premium 11.7.
• Moved to GitLab Core in 13.3.

With the GitLab NPM Registry, every project can have its own space to store NPM packages.

NOTE: Note: Only scoped packages are supported.

Enabling the NPM Registry

NOTE: Note: This option is available only if your GitLab administrator has enabled support for the NPM registry.

Enabling the NPM registry makes it available for all new projects by default. To enable it for existing projects, or if you want to disable it:

1. Navigate to your project's Settings > General > Visibility, project features, permissions.
2. Find the Packages feature and enable or disable it.
3. Click on Save changes for the changes to take effect.

You should then be able to see the Packages & Registries section on the left sidebar.

Before proceeding to authenticating with the GitLab NPM Registry, you should get familiar with the package naming convention.

Getting started

This section covers how to install NPM (or Yarn) and build a package for your JavaScript project. This is a quickstart if you are new to NPM packages. If you are already using NPM and understand how to build your own packages, move on to the next section.

Installing NPM

Follow the instructions at npmjs.com to download and install Node.js and NPM to your local development environment.

Once installation is complete, verify you can use NPM in your terminal by running:

npm --version

You should see the NPM version printed in the output:

6.10.3

Installing Yarn

You may want to install and use Yarn as an alternative to NPM. Follow the instructions at yarnpkg.com to install on your development environment.

Once installed, you can verify that Yarn is available with the following command:

yarn --version

You should see the version printed like so:

1.19.1

Creating a project

Understanding how to create a full JavaScript project is outside the scope of this guide but you can initialize a new empty package by creating and navigating to an empty directory and using the following command:

npm init

Or if you're using Yarn:

yarn init

This takes you through a series of questions to produce a package.json file, which is required for all NPM packages. The most important question is the package name. NPM packages must follow the naming convention and be scoped to the project or group where the registry exists.

Once you have completed the setup, you are now ready to upload your package to the GitLab registry. To get started, you need to set up authentication and then configure GitLab as a remote registry.

Authenticating to the GitLab NPM Registry

If a project is private or you want to upload an NPM package to GitLab, you need to provide credentials for authentication. Personal access tokens and deploy tokens are preferred, but support is available for OAuth tokens.

CAUTION: Two-factor authentication (2FA) is only supported with personal access tokens: If you have 2FA enabled, you need to use a personal access token with OAuth headers with the scope set to api or a deploy token with read_package_registry or write_package_registry scopes. Standard OAuth tokens cannot authenticate to the GitLab NPM Registry.

Authenticating with a personal access token or deploy token

To authenticate with a personal access token or deploy token, set your NPM configuration:

# Set URL for your scoped packages.
# For example package with name `@foo/bar` will use this URL for download
npm config set @foo:registry https://gitlab.com/api/v4/packages/npm/

# Add the token for the scoped packages URL. This will allow you to download
# `@foo/` packages from private projects.
npm config set '//gitlab.com/api/v4/packages/npm/:_authToken' "<your_token>"

# Add token for uploading to the registry. Replace <your_project_id>
# with the project you want your package to be uploaded to.
npm config set '//gitlab.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken' "<your_token>"

Replace <your_project_id> with your project ID which can be found on the home page of your project and <your_token> with your personal access token or deploy token.

If you have a self-managed GitLab installation, replace gitlab.com with your domain name.

You should now be able to download and upload NPM packages to your project.

NOTE: Note: If you encounter an error message with Yarn, see the troubleshooting section.

Using variables to avoid hard-coding auth token values

To avoid hard-coding the authToken value, you may use a variables in its place:

npm config set '//gitlab.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken' "${NPM_TOKEN}"
npm config set '//gitlab.com/api/v4/packages/npm/:_authToken' "${NPM_TOKEN}"

Then, you could run npm publish either locally or via GitLab CI/CD:

• Locally: Export NPM_TOKEN before publishing:

  NPM_TOKEN=<your_token> npm publish

• GitLab CI/CD: Set an NPM_TOKEN variable under your project's Settings > CI/CD > Variables.

Authenticating with a CI job token

Introduced in GitLab Premium 12.5.

If you’re using NPM with GitLab CI/CD, a CI job token can be used instead of a personal access token or deploy token. The token inherits the permissions of the user that generates the pipeline.

Add a corresponding section to your .npmrc file:

@foo:registry=https://gitlab.com/api/v4/packages/npm/
//gitlab.com/api/v4/packages/npm/:_authToken=${CI_JOB_TOKEN}
//gitlab.com/api/v4/projects/${CI_PROJECT_ID}/packages/npm/:_authToken=${CI_JOB_TOKEN}

Uploading packages

Before you can upload a package, you need to specify the registry for NPM. To do this, add the following section to the bottom of package.json:

"publishConfig": {
  "@foo:registry":"https://gitlab.com/api/v4/projects/<your_project_id>/packages/npm/"
}

Replace <your_project_id> with your project ID, which can be found on the home page of your project, and replace @foo with your own scope.

If you have a self-managed GitLab installation, replace gitlab.com with your domain name.

Once you have enabled it and set up authentication, you can upload an NPM package to your project:

npm publish

You can then navigate to your project's Packages & Registries page and see the uploaded packages or even delete them.

Attempting to publish a package with a name that already exists within a given scope causes a 403 Forbidden! error.

Uploading a package with the same version twice

You cannot upload a package with the same name and version twice, unless you delete the existing package first. This aligns with npmjs.org's behavior, with the exception that npmjs.org does not allow users to ever publish the same version more than once, even if it has been deleted.

Package naming convention

Packages must be scoped in the root namespace of the project. The package name may be anything but it is preferred that the project name be used unless it is not possible due to a naming collision. For example:

Project	Package	Supported
foo/bar	@foo/bar	Yes
foo/bar/baz	@foo/baz	Yes
foo/bar/buz	@foo/anything	Yes
gitlab-org/gitlab	@gitlab-org/gitlab	Yes
gitlab-org/gitlab	@foo/bar	No

The regex that is used for naming is validating all package names from all package managers:

/\A\@?(([\w\-\.\+]*)\/)*([\w\-\.]+)@?(([\w\-\.\+]*)\/)*([\w\-\.]*)\z/

It allows for capital letters, while NPM does not, and allows for almost all of the characters NPM allows with a few exceptions (~ is not allowed).

NOTE: Note: Capital letters are needed because the scope is required to be identical to the top level namespace of the project. So, for example, if your project path is My-Group/project-foo, your package must be named @My-Group/any-package-name. @my-group/any-package-name will not work.

CAUTION: When updating the path of a user/group or transferring a (sub)group/project: Make sure to remove any NPM packages first. You cannot update the root namespace of a project with NPM packages. Don't forget to update your .npmrc files to follow the above naming convention and run npm publish if necessary.

Now, you can configure your project to authenticate with the GitLab NPM Registry.

Installing a package

NPM packages are commonly installed using the npm or yarn commands inside a JavaScript project. If you haven't already, set the URL for scoped packages. You can do this with the following command:

npm config set @foo:registry https://gitlab.com/api/v4/packages/npm/

Replace @foo with your scope.

Next, you need to ensure authentication is setup so you can successfully install the package. Once this has been completed, you can run the following command inside your project to install a package:

npm install @my-project-scope/my-package

Or if you're using Yarn:

yarn add @my-project-scope/my-package

Forwarding requests to npmjs.org

Introduced in GitLab Premium 12.9.

By default, when an NPM package is not found in the GitLab NPM Registry, the request is forwarded to npmjs.com.

Administrators can disable this behavior in the Continuous Integration settings.

Removing a package

In the packages view of your project page, you can delete packages by clicking the red trash icons or by clicking the Delete button on the package details page.

Publishing a package with CI/CD

To work with NPM commands within GitLab CI/CD, you can use CI_JOB_TOKEN in place of the personal access token or deploy token in your commands.

A simple example .gitlab-ci.yml file for publishing NPM packages:

image: node:latest

stages:
  - deploy

deploy:
  stage: deploy
  script:
    - echo "//gitlab.com/api/v4/projects/${CI_PROJECT_ID}/packages/npm/:_authToken=${CI_JOB_TOKEN}">.npmrc
    - npm publish

Learn more about using CI_JOB_TOKEN to authenticate to the GitLab NPM registry.

Troubleshooting

Error running Yarn with NPM registry

If you are using Yarn with the NPM registry, you may get an error message like:

yarn install v1.15.2
warning package.json: No license field
info No lockfile found.
warning XXX: No license field
[1/4] 🔍  Resolving packages...
[2/4] 🚚  Fetching packages...
error An unexpected error occurred: "https://gitlab.com/api/v4/projects/XXX/packages/npm/XXX/XXX/-/XXX/XXX-X.X.X.tgz: Request failed \"404 Not Found\"".
info If you think this is a bug, please open a bug report with the information provided in "/Users/XXX/gitlab-migration/module-util/yarn-error.log".
info Visit https://classic.yarnpkg.com/en/docs/cli/install for documentation about this command

In this case, try adding this to your .npmrc file (and replace <your_token> with your personal access token or deploy token):

//gitlab.com/api/v4/projects/:_authToken=<your_token>

npm publish targets default NPM registry (registry.npmjs.org)

Ensure that your package scope is set consistently in your package.json and .npmrc files.

For example, if your project name in GitLab is foo/my-package, then your package.json file should look like:

{
  "name": "@foo/my-package",
  "version": "1.0.0",
  "description": "Example package for GitLab NPM registry",
  "publishConfig": {
    "@foo:registry":"https://gitlab.com/api/v4/projects/<your_project_id>/packages/npm/"
  }
}

And the .npmrc file should look like:

//gitlab.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken=<your_token>
//gitlab.com/api/v4/packages/npm/:_authToken=<your_token>
@foo:registry=https://gitlab.com/api/v4/packages/npm/

npm install returns Error: Failed to replace env in config: ${NPM_TOKEN}

You do not need a token to run npm install unless your project is private (the token is only required to publish). If the .npmrc file was checked in with a reference to $NPM_TOKEN, you can remove it. If you prefer to leave the reference in, you need to set a value prior to running npm install or set the value using GitLab environment variables:

NPM_TOKEN=<your_token> npm install

npm install returns npm ERR! 403 Forbidden

• Check that your token is not expired and has appropriate permissions.
• Check that your token does not begin with -.
• Check if you have attempted to publish a package with a name that already exists within a given scope.
• Ensure the scoped packages URL includes a trailing slash:
  • Correct: //gitlab.com/api/v4/packages/npm/
  • Incorrect: //gitlab.com/api/v4/packages/npm

NPM dependencies metadata

Introduced in GitLab Premium 12.6.

Starting from GitLab 12.6, new packages published to the GitLab NPM Registry expose the following attributes to the NPM client:

• name
• version
• dist-tags
• dependencies
  • dependencies
  • devDependencies
  • bundleDependencies
  • peerDependencies
  • deprecated

NPM distribution tags

Introduced in GitLab Premium 12.8.

You can add distribution tags for newly published packages. They follow NPM's convention where they are optional, and each tag can only be assigned to one package at a time. The latest tag is added by default when a package is published without a tag. The same applies to installing a package without specifying the tag or version.

Examples of the supported dist-tag commands and using tags in general:

npm publish @scope/package --tag               # Publish new package with new tag
npm dist-tag add @scope/package@version my-tag # Add a tag to an existing package
npm dist-tag ls @scope/package                 # List all tags under the package
npm dist-tag rm @scope/package@version my-tag  # Delete a tag from the package
npm install @scope/package@my-tag              # Install a specific tag

CAUTION: Warning: Due to a bug in NPM 6.9.0, deleting dist tags fails. Make sure your NPM version is greater than 6.9.1.
