Google Cloud Storage: Node.js Client

Node.js idiomatic client forCloud Storage.

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

A comprehensive list of changes in each version may be found inthe 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 so you can access theAPI from your local workstation.

Installing the client library

npm install @google-cloud/storage

Using the client library

// Imports the Google Cloud client libraryconst {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 Credentialsconst 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 theNode.js release schedule.Libraries are compatible with all currentactive andmaintenance versions ofNode.js.If you are using an end-of-life version of Node.js, we recommend that you updateas soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on abest-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, andcan be installed through npmdist-tags.The dist-tags follow the naming conventionlegacy-(version).For example,npm install @google-cloud/storage@legacy-8 installs client librariesfor versions compatible with Node.js 8.

Versioning

This library followsSemantic Versioning.

This library is considered to bestable. The code surface will not change in backwards-incompatible waysunless absolutely necessary (e.g. because of critical security issues) or withan extensive deprecation period. Issues and requests againststable librariesare addressed with the highest priority.
