Before you begin

1. If the target repository does not exist, create a new repository.
2. Verify that you have the required permissions for the repository.
3. Configure authentication for npm.
4. (Optional) Configure defaults for gcloud commands.

Adding packages

You can only publish a specific version of a package once. This is an npm restriction to ensure that the contents of a published package version are always the same. As a result, you cannot:

• Overwrite a package version by publishing it again to the repository
• Remove a package or its version from the repository, and then publish a package with the same name and version number

To add a package:

1. Ensure that the package name in package.json includes the scope configured for your repository. The following example shows a package with the scope dev-repo.

   "name": "@dev-repo/my-package"
   

2. Refresh the access token for connecting to the repository. google-artifactregistry-auth is a client library that updates credentials for Artifact Registry repositories.

   To refresh credentials, use one of these options:

   • Use npx directly to refresh the access token. If you are using npm 5.2.0 or newer, it is included with npm.

     1. Ensure that credentials for connecting to the public npm registry are in your user npm configuration file, ~/.npmrc.

     2. Run the following command in the folder above your npm project.

     npx google-artifactregistry-auth PROJECT-NPMRC
     

     Where PROJECT-NPMRC is the path to the .npmrc file in your project directory.

     You must run the command outside of your project directory so that npx uses your public npm registry credentials in ~/.npmrc to download google-artifactregistry-auth.

   • Add a script to the package.json file in your project.

     "scripts": {
       "artifactregistry-login": "npx google-artifactregistry-auth"
     }
     

     npm run artifactregistry-login PROJECT-NPMRC --registry https://registry.npmjs.org/
     

     Where PROJECT-NPMRC is the path to the .npmrc file in your project directory.

   • For versions of npm older than 5.2.0, perform the following steps:

     1. Run the command:

     npm install google-artifactregistry-auth --save-dev --registry https://registry.npmjs.org/
     

     1. Add it to an authentication script:

     "scripts": {
         "artifactregistry-login": "./node_modules/.bin/artifactregistry-auth",
     }
     

     Run the script

     npm run artifactregistry-login PROJECT-NPMRC
     

     Where PROJECT-NPMRC is the path to the .npmrc file in your project directory.

3. Add packages to the repository. You can use an npm or yarn command.

   npm publish
   

   yarn publish
   

Viewing packages and versions

To get package information with npm or yarn, run the appropriate command:

npm view

yarn info

To view packages and package versions using the Google Cloud Console or gcloud:

Console

1. Open the Repositories page in the Google Cloud Console.

   Open the Repositories page

2. In the repository list, click the appropriate repository.

   The Packages page lists the packages in the repository.

3. Click a package to view versions of the package.

gcloud

To list packages in a repository, run the following command:

gcloud artifacts packages list [--repository=REPOSITORY] [--location=LOCATION]

Where

• REPOSITORY is the name of the repository. If you configured a default repository, you can omit this flag to use the default.
• LOCATION is a regional or multi-regional location. Use this flag to view repositories in a specific location. If you configured a default location, you can omit this flag to use the default.

To view versions of a package, run the following command:

gcloud artifacts versions list --package=PACKAGE \
    [--repository=REPOSITORY] [--location=LOCATION]

Where

• PACKAGE is the ID of the package or fully qualified identifier for the package.
• REPOSITORY is the name of the repository. If you configured a default repository, you can omit this flag to use the default.
• LOCATION is a regional or multi-regional location. Use this flag to view repositories in a specific location. If you configured a default location, you can omit this flag to use the default.

Tagging packages

You can view, add, update, and delete tags.

Viewing tags

To view tags for a package:

Console

1. Open the Repositories page in the Cloud Console.

   Open the Repositories page

yarn add PACKAGE

When you specify a package as a dependency in package.json, ensure that you include the scope for the repository. The following example shows the @dev-repo scope for a package named my-package.

"dependencies": {
  "@dev-repo/my-package": ">=1.0.0"
}

Deleting packages

Before you delete a package or package version, verify that any you have communicated or addressed any important dependencies on it.

After a package version is published, you cannot republish a package with the same name and version combination, even after deleting the version. This is an npm restriction to ensure that the contents of a published package version are always the same.

If you want to encourage users to install an updated package version, use the npm deprecate command to mark the old version of the package as deprecated. When a user tries to install the deprecated package, Artifact Registry returns a deprecation warning.
