Artifact Registry supports Node.js packages that you manage with npm.

Overview

To get familiar with Node.js packages in Artifact Registry, you can try the quickstart.

When you are ready to learn more, read the following information:

  1. If you are new to npm, read about the following concepts:
  2. Create a Node.js package repository for your packages.
  3. Grant permissions to the account that will connect with the repository. Service accounts for common integrations with Artifact Registry have default permissions for repositories in the same project.
  4. Configure your tools:
  5. Learn about managing packages.

Using scopes

An npm scope is a label for grouping packages. Scopes are necessary when you are working with multiple npm registries, including:

  • Publishing and installing packages in different registries without the need to switch from one registry to another. For example, your builds might include packages from both the public npm registry and an Artifact Registry repository.
  • Publishing the same packages to multiple Artifact Registry repositories across Google Cloud projects, as well as other npm registries, without package name conflicts.

We recommend that you always set a scope for your repositories. If you do not specify a scope when you publish or install package, npm uses the configured default registry, such as the public npm registry.

You set the scope for each Artifact Registry repository in the .npmrc configuration file. The same credentials for authentication apply across the repositories.

The following example shows configuration for two Artifact Registry repositories in different projects.

  • The @blue scope is for the repository in the project blue-project.
  • The @green scope is for the repository in the project green-project.
@blue:registry=https://us-central1-npm.pkg.dev/blue-project/blue-npm-repo/
//us-central1-npm.pkg.dev/blue-project/blue-npm-repo/:always-auth=true

@green:registry=https://us-central1-npm.pkg.dev/green-project/green-npm-repo/
//us-central1-npm.pkg.dev/green-project/green-npm-repo/:_authToken=""
//us-central1-npm.pkg.dev/green-project/green-npm-repo/:always-auth=true

After you have authenticated to Artifact Registry, you can upload a package to a particular repository using the appropriate scope. For example, the following command uploads a package to the blue-npm-repo in the project blue-project:

npm publish @blue/blue-npm-repo

For more information about scopes, see the npm documentation

Configuring npm

Settings used for authentication are stored in the .npmrc configuration file. You can configure an .npmrc file at the project, user, or global level.

When you configure authentication with Artifact Registry, you define the repositories that you want to connect to and the credentials for authentication.

Artifact Registry repositories

We recommend setting the repository list in the per-project config file. This file is usually in the same directory as the package.json file in your npm project. The Artifact Registry credential helper checks this .npmrc file for your repositories by default.

If you do not want to expose the repository paths in your source control system, you can:

  • Add the .npmrc filename your source control's list of files to ignore.
  • Store the repository list in your per-user confg file instead. The per-user .npmrc file is in your user home directory, or is set with the npm --userconfig parameter or $NPM_CONFIG_USERCONFIG environment variable. Settings in the per-user config file apply to all your projects unless you override them at the project level.
Artifact Registry credentials

Store your credentials for Artifact Registry in the per-user config file so that they are not available to other users. This file is located in your user home directory, or is set with the npm --userconfig parameter or $NPM_CONFIG_USERCONFIG environment variable.

The Artifact Registry credential helper is stored in the public npm registry and does not require authentication for installation.

You should retain any existing default registry configured in your .npmrc file. The default is typically set to the public npm registry at https://registry.npmjs.org/.

To check the current default registry value run the command:

npm get registry
