What is @aws-sdk/client-ec2?

@aws-sdk/client-ec2 is a part of the AWS SDK for JavaScript, which allows developers to interact with Amazon EC2 (Elastic Compute Cloud) services. This package provides a comprehensive set of functionalities to manage EC2 instances, security groups, key pairs, and other related resources programmatically.

What are @aws-sdk/client-ec2's main functionalities?

Launch an EC2 Instance

This code sample demonstrates how to launch a new EC2 instance using the @aws-sdk/client-ec2 package. It specifies the AMI ID, instance type, and the number of instances to launch.

const { EC2Client, RunInstancesCommand } = require('@aws-sdk/client-ec2');

const client = new EC2Client({ region: 'us-west-2' });

const run = async () => {
  const command = new RunInstancesCommand({
    ImageId: 'ami-0abcdef1234567890',
    InstanceType: 't2.micro',
    MinCount: 1,
    MaxCount: 1
  });
  const response = await client.send(command);
  console.log(response);
};

run();

Describe EC2 Instances

This code sample shows how to describe EC2 instances using the @aws-sdk/client-ec2 package. It retrieves information about all EC2 instances in the specified region.

const { EC2Client, DescribeInstancesCommand } = require('@aws-sdk/client-ec2');

const client = new EC2Client({ region: 'us-west-2' });

const describe = async () => {
  const command = new DescribeInstancesCommand({});
  const response = await client.send(command);
  console.log(response);
};

describe();

Terminate an EC2 Instance

This code sample demonstrates how to terminate an EC2 instance using the @aws-sdk/client-ec2 package. It specifies the instance ID of the EC2 instance to be terminated.

const { EC2Client, TerminateInstancesCommand } = require('@aws-sdk/client-ec2');

const client = new EC2Client({ region: 'us-west-2' });

const terminate = async () => {
  const command = new TerminateInstancesCommand({
    InstanceIds: ['i-0abcdef1234567890']
  });
  const response = await client.send(command);
  console.log(response);
};

terminate();

Create a Security Group

This code sample shows how to create a new security group using the @aws-sdk/client-ec2 package. It specifies the group name, description, and VPC ID.

const { EC2Client, CreateSecurityGroupCommand } = require('@aws-sdk/client-ec2');

const client = new EC2Client({ region: 'us-west-2' });

const createSecurityGroup = async () => {
  const command = new CreateSecurityGroupCommand({
    GroupName: 'my-security-group',
    Description: 'My security group',
    VpcId: 'vpc-0abcdef1234567890'
  });
  const response = await client.send(command);
  console.log(response);
};

createSecurityGroup();

Description

AWS SDK for JavaScript EC2 Client for Node.js, Browser and React Native.

Amazon Elastic Compute Cloud

You can access the features of Amazon Elastic Compute Cloud (Amazon EC2) programmatically. For more information, see the Amazon EC2 Developer Guide.

Installing

To install this package, simply type add or install @aws-sdk/client-ec2 using your favorite package manager:

npm install @aws-sdk/client-ec2
yarn add @aws-sdk/client-ec2
pnpm add @aws-sdk/client-ec2

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the EC2Client and the commands you need, for example ListImagesInRecycleBinCommand:

// ES5 example
const { EC2Client, ListImagesInRecycleBinCommand } = require("@aws-sdk/client-ec2");

// ES6+ example
import { EC2Client, ListImagesInRecycleBinCommand } from "@aws-sdk/client-ec2";

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 EC2Client({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new ListImagesInRecycleBinCommand(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-ec2";
const client = new AWS.EC2({ region: "REGION" });

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

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

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