Description

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

AWS Health

The AWS Health API provides programmatic access to the AWS Health information that appears in the AWS Personal Health Dashboard. You can use the API operations to get information about AWS Health events that affect your AWS services and resources.

You must have a Business or Enterprise support plan from AWS Support to use the AWS Health API. If you call the AWS Health API from an AWS account that doesn't have a Business or Enterprise support plan, you receive a SubscriptionRequiredException error.

AWS Health has a single endpoint: health.us-east-1.amazonaws.com (HTTPS). Use this endpoint to call the AWS Health API operations.

For authentication of requests, AWS Health uses the Signature Version 4 Signing Process.

If your AWS account is part of AWS Organizations, you can use the AWS Health organizational view feature. This feature provides a centralized view of AWS Health events across all accounts in your organization. You can aggregate AWS Health events in real time to identify accounts in your organization that are affected by an operational event or get notified of security vulnerabilities. Use the organizational view API operations to enable this feature and return event information. For more information, see Aggregating AWS Health events in the AWS Health User Guide.

When you use the AWS Health API operations to return AWS Health events, see the following recommendations:

• Use the eventScopeCode parameter to specify whether to return AWS Health events that are public or account-specific.

• Use pagination to view all events from the response. For example, if you call the DescribeEventsForOrganization operation to get all events in your organization, you might receive several page results. Specify the nextToken in the next request to return more results.

Installing

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

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

Getting Started

Import

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

// ES5 example
const { HealthClient, DescribeAffectedAccountsForOrganizationCommand } = require("@aws-sdk/client-health");

// ES6+ example
import { HealthClient, DescribeAffectedAccountsForOrganizationCommand } from "@aws-sdk/client-health";

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 difference commands.
const client = new HealthClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new DescribeAffectedAccountsForOrganizationCommand(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) => {
  // proccess 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-health";
const client = new AWS.Health({ region: "REGION" });

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

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

// callbacks.
client.describeAffectedAccountsForOrganization(params, (err, data) => {
  // proccess 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;
   * }
   */
}
