Description

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

Storage Gateway Service

Amazon FSx File Gateway is no longer available to new customers. Existing customers of FSx File Gateway can continue to use the service normally. For capabilities similar to FSx File Gateway, visit this blog post.

Storage Gateway is the service that connects an on-premises software appliance with cloud-based storage to provide seamless and secure integration between an organization's on-premises IT environment and the Amazon Web Services storage infrastructure. The service enables you to securely upload data to the Amazon Web Services Cloud for cost effective backup and rapid disaster recovery.

Use the following links to get started using the Storage Gateway Service API Reference:

• Storage Gateway required request headers: Describes the required headers that you must send with every POST request to Storage Gateway.

• Signing requests: Storage Gateway requires that you authenticate every request you send; this topic describes how sign such a request.

• Error responses: Provides reference information about Storage Gateway errors.

• Operations in Storage Gateway: Contains detailed descriptions of all Storage Gateway operations, their request parameters, response elements, possible errors, and examples of requests and responses.

• Storage Gateway endpoints and quotas: Provides a list of each Amazon Web Services Region and the endpoints available for use with Storage Gateway.

Installing

To install this package, simply type add or install @aws-sdk/client-storage-gateway using your favorite package manager:

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

Getting Started

Import

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

// ES5 example
const { StorageGatewayClient, ListTapesCommand } = require("@aws-sdk/client-storage-gateway");

// ES6+ example
import { StorageGatewayClient, ListTapesCommand } from "@aws-sdk/client-storage-gateway";

Usage

To send a request, you:

• Initiate client with configuration (e.g. credentials, region).
• Initiate command with input parameters.
• Call send operation on client with command object as input.
• If you are using a custom http handler, you may call destroy() to close open connections.

// a client can be shared by different commands.
const client = new StorageGatewayClient({ region: "REGION" });

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

Async/await

We recommend using 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.
}

Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.

Promises

You can also use Promise chaining to execute send operation.

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

Promises can also be called using .catch() and .finally() as follows:

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

Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// callbacks.
client.send(command, (err, data) => {
  // process err and data.
});

v2 compatible style

The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript

import * as AWS from "@aws-sdk/client-storage-gateway";
const client = new AWS.StorageGateway({ region: "REGION" });

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

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

// callbacks.
client.listTapes(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;
   * }
   */
}
