Description

AWS SDK for JavaScript Glacier Client for Node.js, Browser and React Native.

Amazon Glacier (Glacier) is a storage solution for "cold data."

Glacier is an extremely low-cost storage service that provides secure, durable, and easy-to-use storage for data backup and archival. With Glacier, customers can store their data cost effectively for months, years, or decades. Glacier also enables customers to offload the administrative burdens of operating and scaling storage to AWS, so they don't have to worry about capacity planning, hardware provisioning, data replication, hardware failure and recovery, or time-consuming hardware migrations.

Glacier is a great storage choice when low storage cost is paramount and your data is rarely retrieved. If your application requires fast or frequent access to your data, consider using Amazon S3. For more information, see Amazon Simple Storage Service (Amazon S3).

You can store any kind of data in any format. There is no maximum limit on the total amount of data you can store in Glacier.

If you are a first-time user of Glacier, we recommend that you begin by reading the following sections in the Amazon Glacier Developer Guide:

• What is Amazon Glacier - This section of the Developer Guide describes the underlying data model, the operations it supports, and the AWS SDKs that you can use to interact with the service.

• Getting Started with Amazon Glacier - The Getting Started section walks you through the process of creating a vault, uploading archives, creating jobs to download archives, retrieving the job output, and deleting archives.

Installing

To install this package, use the CLI of your favorite package manager:

• npm install @aws-sdk/client-glacier
• yarn add @aws-sdk/client-glacier
• pnpm add @aws-sdk/client-glacier

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the GlacierClient and the commands you need, for example ListVaultsCommand:

// ES5 example
const { GlacierClient, ListVaultsCommand } = require("@aws-sdk/client-glacier");

// ES6+ example
import { GlacierClient, ListVaultsCommand } from "@aws-sdk/client-glacier";

Usage

To send a request:

• Instantiate a client with configuration (e.g. credentials, region).
  • See docs/CLIENTS for configuration details.
  • See @aws-sdk/config for additional options.
• Instantiate a command with input parameters.
• Call the send operation on the client, providing the command object as input.

const client = new GlacierClient({ region: "REGION" });

const params = { /** input parameters */ };
const command = new ListVaultsCommand(params);

Async/await

We recommend using the await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
} finally {
  // finally.
}

Promises

You can also use Promise chaining.

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });

Aggregated client

The aggregated client class is exported from the same package, but without the "Client" suffix.

Glacier extends GlacierClient and additionally supports all operations, waiters, and paginators as methods. This style may be familiar to you from the AWS SDK for JavaScript v2.

If you are bundling the AWS SDK, we recommend using only the bare-bones client (GlacierClient). More details are in the blog post on modular packages in AWS SDK for JavaScript.

import { Glacier } from "@aws-sdk/client-glacier";

const client = new Glacier({ region: "REGION" });

// async/await.
try {
  const data = await client.listVaults(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listVaults(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks (not recommended).
client.listVaults(params, (err, data) => {
  // process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  const { requestId, cfId, extendedRequestId } = error.$metadata;
  console.log({ requestId, cfId, extendedRequestId });
  /**
   * The keys within exceptions are also parsed.
   * You can access them by specifying exception names:
   * if (error.name === 'SomeServiceException') {
   *     const value = error.specialKeyInException;
   * }
   */
}
