Google Cloud Client Library for Node.js

Cloud Node.js Client

Node.js idiomatic client for Google Cloud Platform services.

• Homepage
• API Documentation

This client supports the following Google Cloud Platform services at a General Availability (GA) quality level:

• Cloud Datastore (GA)
• Cloud Storage (GA)
• Google Stackdriver Logging (GA)

This client supports the following Google Cloud Platform services at a Beta quality level:

• Cloud Natural Language (Beta)
• Cloud Translation API (Beta)
• Cloud Vision (Beta)
• Google BigQuery (Beta)

This client supports the following Google Cloud Platform services at an Alpha quality level:

• Google Stackdriver Monitoring (Alpha)

If you need support for other Google APIs, check out the Google Node.js API Client library.

Quick Start

We recommend installing the individual packages that you need, which are provided under the @google-cloud namespace. For example:

$ npm install --save @google-cloud/datastore
$ npm install --save @google-cloud/storage

var config = {
  projectId: 'grape-spaceship-123',
  keyFilename: '/path/to/keyfile.json'
};

var datastore = require('@google-cloud/datastore')(config);
var storage = require('@google-cloud/storage')(config);

The google-cloud meta-package

We also provide a meta-package, google-cloud, which provides all of the individual APIs. However, in order to keep file size and memory use low, the use of this package is not recommended.

If you want the kitchen sink, however, get it with:

$ npm install --save google-cloud

var gcloud = require('google-cloud')({
  projectId: 'grape-spaceship-123',
  keyFilename: '/path/to/keyfile.json'
});

var datastore = gcloud.datastore();
var storage = gcloud.storage();

Example Applications

• nodejs-getting-started - A sample and tutorial that demonstrates how to build a complete web application using Cloud Datastore, Cloud Storage, and Cloud Pub/Sub and deploy it to Google App Engine or Google Compute Engine.
• gcloud-node-todos - A TodoMVC backend using google-cloud-node and Datastore.
• gitnpm - Easily lookup an npm package's GitHub repo using google-cloud-node and Google App Engine.
• gcloud-kvstore - Use Datastore as a simple key-value store.
• hya-wave - Cloud-based web sample editor. Part of the hya-io family of products.
• gstore-node - Google Datastore Entities Modeling library.
• gstore-api - REST API builder for Google Datastore Entities.

Authentication

With google-cloud it's incredibly easy to get authenticated and start using Google's APIs. You can set your credentials on a global basis as well as on a per-API basis. See each individual API section below to see how you can auth on a per-API-basis. This is useful if you want to use different accounts for different Cloud services.

On Google Cloud Platform

If you are running this client on Google Cloud Platform, we handle authentication for you with no configuration. You just need to make sure that when you set up the GCE instance, you add the correct scopes for the APIs you want to access.

var gcloud = require('google-cloud');
// ...you're good to go! See the next section to get started using the APIs.

Elsewhere

If you are not running this client on Google Cloud Platform, you need a Google Developers service account. To create a service account:

1. Visit the Google Developers Console.
2. Create a new project or click on an existing project.
3. Navigate to APIs & auth > APIs section and turn on the following APIs (you may need to enable billing in order to use these services):

• BigQuery API
• Cloud Bigtable API
• Cloud Bigtable Admin API
• Cloud Bigtable Table Admin API
• Cloud Spanner API
• Google Cloud Datastore API
• Google Cloud DNS API
• Google Cloud Natural Language API
• Google Cloud Pub/Sub API
• Google Cloud Resource Manager API
• Google Cloud Speech API
• Google Cloud Storage
• Google Cloud Storage JSON API
• Google Cloud Translation API
• Google Cloud Vision API
• Google Compute Engine API
• Prediction API
• Stackdriver Logging API

4. Navigate to APIs & auth > Credentials and then:

• If you want to use a new service account key, click on Create credentials and select Service account key. After the account key is created, you will be prompted to download the JSON key file that the library uses to authenticate your requests.
• If you want to generate a new service account key for an existing service account, click on Generate new JSON key and download the JSON key file.

// Authenticating on a global basis.
var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123'

var gcloud = require('google-cloud')({
  projectId: projectId,

  // The path to your key file:
  keyFilename: '/path/to/keyfile.json'

  // Or the contents of the key file:
  credentials: require('./path/to/keyfile.json')

  // For any APIs that accept an API key:
  key: '...'
});

// ...you're good to go! See the next section to get started using the APIs.

You can also set auth on a per-API-instance basis. The examples below show you how.

Google Stackdriver Monitoring (Alpha)

⚠️ This is an auto-generated API

It does not follow the conventions you're familiar with from other parts of our library. A handwritten layer is not yet available.

The example below shows you how to instantiate the generated client. For further documentation, please browse the Monitoring .proto files on GitHub.

• Official Documentation

Using the Google Stackdriver Monitoring API module

$ npm install --save @google-cloud/monitoring

var monitoring = require('@google-cloud/monitoring');

Preview

var monitoringClient = monitoring.v3({
  projectId: 'grape-spaceship-123',
  keyFilename: '/path/to/keyfile.json'
});

Versioning

This library follows Semantic Versioning.

Please note it is currently under active development. Any release versioned 0.x.y is subject to backwards-incompatible changes at any time.

GA: Libraries defined at the GA (general availability) quality level are stable. The code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.

Please note that the auto-generated portions of the GA libraries (the ones in modules such as v1 or v2) are considered to be of Beta quality, even if the libraries that wrap them are GA.

Beta: Libraries defined at the Beta quality level are expected to be mostly stable, while we work towards their release candidate. We will address issues and requests with a higher priority.

Alpha: Libraries defined at the Alpha quality level are still a work-in-progress and are more likely to get backwards-incompatible updates.

Contributions to this library are always welcome and highly encouraged.
