Quickstart for Node.js

This quickstart shows you how to set up an Artifact Registry Node.js package repository and upload a package to it.

Before you begin

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

Go to project selector
Make sure that billing is enabled for your Cloud project. Learn how to confirm that billing is enabled for your project.
Enable the Artifact Registry API.
Enable the API

Install and initialize the Cloud SDK.
Install PowerShell, if you want to connect to a Node.js package repository from Windows.

Create a Node.js package repository

Create the repository for your Node.js artifacts.

Create the repository.
Console
1. Open the Repositories page in the Cloud Console.
  
  Open the Repositories page
2. Click Create Repository.
3. Specify quickstart-nodejs-repo as the repository name.
4. Choose npm as the format.
5. Under Location Type, select Region and then choose the location us-central1.
6. Click Create.
The repository is added to the repository list
gcloud
1. Run the following command to create a new Node.js package repository named quickstart-nodejs-repo in the location us-central1 with the description "Node.js repository".
```
gcloud artifacts repositories create quickstart-nodejs-repo --repository-format=npm \
--location=us-central1 [--description="Node.js package repository"]
```
2. Run the following command to verify that your repository was created.
```
gcloud artifacts repositories list
```
For more information about Artifact Registry commands, run the command gcloud artifacts.
To simplify gcloud commands, set the default repository to quickstart-nodejs-repo and the default location to us-central1. After the values are set, you do not need to specify them in gcloud commands that require a repository or a location.

To set the repository, run the command:
```
gcloud config set artifacts/repository quickstart-nodejs-repo
```
To set the location, run the command:
```
gcloud config set artifacts/location us-central1
```
For more information about these commands, see the gcloud config set documentation.

Set up a service account for your client

Create or choose an existing service account to act on behalf of npm.

Create a service account to act on behalf of your application, or choose an existing service account that you use for automation.

You will need the location of the service account key file to set up authentication with Artifact Registry. For existing accounts, you can view keys and create new keys on the Service Accounts page.

Go to the Service Accounts page

Grant the service account read and write access to your repository.

gcloud artifacts repositories add-iam-policy-binding \
quickstart-nodejs-repo --location=us-central1 --member=serviceAccount:ACCOUNT --role=roles/artifactregistry.writer

Where ACCOUNT is the ID of your service account in the format USERNAME@PROJECT-ID.iam.gserviceaccount.com.

Assign the service account key file location to the variable GOOGLE_APPLICATION_CREDENTIALS so that the Artifact Registry credential helper can obtain your key when connecting with repositories.
```
export GOOGLE_APPLICATION_CREDENTIALS=KEY-FILE
```
Where KEY-FILE is path to the service account key file.

To learn about setting up password authentication with the service account key file instead, see authentication#auth-password documentation.

Configure npm

Create an npm package to upload. If you don't have a package available to use with this quickstart, run the following command to create a plain package.json file:
```
npm init -y
```
Configure your npm project to deploy to the Artifact Registry repository that you created.
1. Run the following command. The command returns configuration settings to add to your npm configuration file.
```
gcloud artifacts print-settings npm --scope=@quickstart
```
  The quickstart scope is associated with your repository. When you include the scope in commands to publish or install packages, npm uses your repository. When you publish or install packages without a scope, your configured default repository is used. For more information, see the Node.js overview.
  
  The output of the gcloud command looks like this:
```
@quickstart:registry=https://us-central1-npm.pkg.dev/PROJECT/quickstart-nodejs-repo/
//us-central1-npm.pkg.dev/PROJECT/quickstart-nodejs-repo/:_authToken=""
//us-central1-npm.pkg.dev/PROJECT/quickstart-nodejs-repo/:always-auth=true
```
2. Add the configuration settings from the previous step to your project .npmrc file. The file is usually in the same directory as the package.json file.
  
  Replace PROJECT with your project ID.
  
  To learn more about the .npmrc file, see the Node.js overview.

Each Artifact Registry Node.js package repository is associated with an npm registry endpoint https://LOCATION-npm.pkg.dev/PROJECT/REPOSITORY. If you create another Artifact Registry Node.js package repository, npm interacts with it as a separate registry with its own scope.

Upload a package to the repository

Choose a package to upload. Ensure that package name in package.json includes the quickstart scope.
```
"name": "@quickstart/my-package"
```
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:
- Add a script to the package.json file in your project.
```
"scripts": {
  "artifactregistry-login": "npx google-artifactregistry-auth"
}
```
  Run the script with the command:
```
npm run artifactregistry-login PROJECT-NPMRC
```
  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 with the command:
```
npm run artifactregistry-login PROJECT-NPMRC
```
  Where PROJECT-NPMRC is the path to the .npmrc file in your project directory.
Add your package to the repository. You can use an npm or yarn command.
```
npm publish
```
```
yarn publish
```

View the package in the repository

To verify that your package was added to the repository:

Console

Open the Repositories page in the Cloud Console.

Open the Repositories page
In the repository list, click the quickstart-nodejs-repo repository.

The Packages page lists the packages in the repository.
Click on a package to view package versions.

gcloud

To list the images in the default quickstart-nodejs-repo repository, run the following command:

 gcloud artifacts packages list

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

gcloud artifacts versions list --package=PACKAGE

Where PACKAGE is the package ID.

Installing packages

To install a package from the Node.js package repository, use the npm install or yarn add command. Replace PACKAGE with your package name.

npm install @quickstart/PACKAGE

yarn add @quickstart/PACKAGE

Clean up

To avoid incurring charges to your Google Cloud account for the resources used in this quickstart, follow these steps.

Before you remove a repository, ensure that any packages that you want to keep are available in another location.

To delete the repository:

Console

Open the Repositories page in the Cloud Console.

Open the Repositories page
In the repository list, select the quickstart-nodejs-repo repository.
Click Delete.

gcloud

To delete the quickstart-nodejs-repo repository, run the following command:
```
gcloud artifacts repositories delete quickstart-nodejs-repo
```
If you want to remove the default repository and location settings that you configured for the active gcloud configuration, run the following commands:
```
gcloud config unset artifacts/repository
gcloud config unset artifacts/location
```
