Description

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

Amazon Elastic Compute Cloud

This is the Amazon EC2 API Reference. It provides descriptions, API request parameters, and the XML response for each of the Amazon EC2 Query API actions. Note that the Amazon EC2 API includes actions for Amazon EC2 plus additional services, such as Amazon EBS and Amazon VPC.

Learn more

• To learn about using the Query API, see Using the API for Amazon EC2.

• To learn about the permissions required to call an Amazon EC2 API action, see Actions, resources, and condition keys for Amazon EC2.

• To get the list of API actions by service and resource, see Actions by service.

• To get the alphabetical list of API actions, see .

• To get descriptions of the API error codes, see Error codes for the Amazon EC2 API.

Alternatively, use one of the following methods to access the Amazon EC2 API, instead of using the Query API directly:

• Amazon Web Services CLI Command Reference - ec2 commands

• CloudFormation - Amazon EC2 resource type reference

• Amazon Web Services Tools for PowerShell Cmdlet Reference - Amazon EC2 cmdlets

• Amazon Web Services SDKs

Installing

To install this package, use the CLI of 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:

• Instantiate a client with configuration (e.g. credentials, region).
  • See docs/CLIENTS for configuration details.
  • See @aws-sdk/config for additional options.
• Instantiate a command with input parameters.
• Call the send operation on the client, providing the command object as input.

const client = new EC2Client({ region: "REGION" });

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

Async/await

We recommend using the 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.
}

Promises

You can also use Promise chaining.

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.

EC2 extends EC2Client 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 (EC2Client). More details are in the blog post on modular packages in AWS SDK for JavaScript.

import { EC2 } from "@aws-sdk/client-ec2";

const client = new 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 (not recommended).
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;
   * }
   */
}
