Description

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

<p>Welcome to the API Reference Guide for zonal shift and zonal autoshift in Amazon Application Recovery Controller (ARC).</p> <p>You can start a zonal shift to move traffic for a load balancer resource away from an Availability Zone to help your application recover quickly from an impairment in an Availability Zone. For example, you can recover your application from a developer's bad code deployment or from an Amazon Web Services infrastructure failure in a single Availability Zone.</p> <p>You can also configure zonal autoshift for supported load balancer resources. Zonal autoshift is a capability in ARC where you authorize Amazon Web Services to shift away application resource traffic from an Availability Zone during events, on your behalf, to help reduce your time to recovery. Amazon Web Services starts an autoshift when internal telemetry indicates that there is an Availability Zone impairment that could potentially impact customers.</p> <p>For more information about using zonal shift and zonal autoshift, see the <a href="https://docs.aws.amazon.com/r53recovery/latest/dg/what-is-route53-recovery.html">Amazon Application Recovery Controller Developer Guide</a>.</p>

Installing

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

  • npm install @aws-sdk/client-arc-zonal-shift
  • yarn add @aws-sdk/client-arc-zonal-shift
  • pnpm add @aws-sdk/client-arc-zonal-shift

Getting Started

Import

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

js
// ES5 example
const { ARCZonalShiftClient, ListAutoshiftsCommand } = require("@aws-sdk/client-arc-zonal-shift");
ts
// ES6+ example
import { ARCZonalShiftClient, ListAutoshiftsCommand } from "@aws-sdk/client-arc-zonal-shift";

Usage

To send a request:

  • Instantiate a client with configuration (e.g. credentials, region).
  • Instantiate a command with input parameters.
  • Call the send operation on the client, providing the command object as input.
js
const client = new ARCZonalShiftClient({ region: "REGION" });

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

Async/await

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

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

Promises

You can also use Promise chaining.

js
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.

ARCZonalShift extends ARCZonalShiftClient 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 (ARCZonalShiftClient). More details are in the blog post on modular packages in AWS SDK for JavaScript.

ts
import { ARCZonalShift } from "@aws-sdk/client-arc-zonal-shift";

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

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

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

// callbacks (not recommended).
client.listAutoshifts(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).

js
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;
   * }
   */
}
