Google Cloud Storage: Node.js Client

Node.js idiomatic client for Cloud Storage.

Cloud Storage allows world-wide storage and retrieval of any amount of data at any time. You can use Google Cloud Storage for a range of scenarios including serving website content, storing data for archival and disaster recovery, or distributing large data objects to users via direct download.

A comprehensive list of changes in each version may be found in the CHANGELOG.

Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Google Cloud Storage API.
4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install @google-cloud/storage

Using the client library

// Imports the Google Cloud client library
const {Storage} = require('@google-cloud/storage');

// For more information on ways to initialize Storage, please see
// https://googleapis.dev/nodejs/storage/latest/Storage.html

// Creates a client using Application Default Credentials
const storage = new Storage();

// Creates a client from a Google service account key
// const storage = new Storage({keyFilename: 'key.json'});

/**
 * TODO(developer): Uncomment these variables before running the sample.
 */
// The ID of your GCS bucket
// const bucketName = 'your-unique-bucket-name';

async function createBucket() {
  // Creates the new bucket
  await storage.createBucket(bucketName);
  console.log(`Bucket ${bucketName} created.`);
}

createBucket().catch(console.error);

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

• Legacy versions are not tested in continuous integration.
• Some security patches and features cannot be backported.
• Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/storage@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be 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 stable libraries are addressed with the highest priority.
