Description

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

AWS Systems Manager

AWS Systems Manager is a collection of capabilities that helps you automate management tasks such as collecting system inventory, applying operating system (OS) patches, automating the creation of Amazon Machine Images (AMIs), and configuring operating systems (OSs) and applications at scale. Systems Manager lets you remotely and securely manage the configuration of your managed instances. A managed instance is any Amazon Elastic Compute Cloud instance (EC2 instance), or any on-premises server or virtual machine (VM) in your hybrid environment that has been configured for Systems Manager.

This reference is intended to be used with the AWS Systems Manager User Guide.

To get started, verify prerequisites and configure managed instances. For more information, see Setting up AWS Systems Manager in the AWS Systems Manager User Guide.

For information about other API actions you can perform on EC2 instances, see the Amazon EC2 API Reference. For information about how to use a Query API, see Making API requests.

Installing

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

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

Getting Started

Import

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

// ES5 example
const { SSMClient, AddTagsToResourceCommand } = require("@aws-sdk/client-ssm");

// ES6+ example
import { SSMClient, AddTagsToResourceCommand } from "@aws-sdk/client-ssm";

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 SSMClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new AddTagsToResourceCommand(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-ssm";
const client = new AWS.SSM({ region: "REGION" });

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

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

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