aws-sdk

What is aws-sdk?

The aws-sdk npm package is the official AWS SDK for JavaScript, providing JavaScript objects for AWS services including Amazon S3, EC2, DynamoDB, and more. It allows developers to interact with AWS services programmatically, enabling them to build scalable solutions with AWS infrastructure.

What are aws-sdk's main functionalities?

Interacting with Amazon S3

This code sample demonstrates how to retrieve an object from an Amazon S3 bucket using the aws-sdk.

{"const AWS = require('aws-sdk');
const s3 = new AWS.S3();
const params = { Bucket: 'myBucket', Key: 'myKey' };
s3.getObject(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

Managing EC2 Instances

This code sample shows how to describe EC2 instances, providing information about instances running in your AWS account.

{"const AWS = require('aws-sdk');
const ec2 = new AWS.EC2();
const params = { InstanceIds: ['i-1234567890abcdef0'] };
ec2.describeInstances(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

Working with DynamoDB

This code sample illustrates how to retrieve an item from a DynamoDB table using the aws-sdk.

{"const AWS = require('aws-sdk');
const dynamoDB = new AWS.DynamoDB();
const params = {
  TableName: 'myTable',
  Key: {
    'myKey': { S: 'myKeyValue' }
  }
};
dynamoDB.getItem(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

Other packages similar to aws-sdk

google-cloud

The google-cloud package is a client library for accessing Google Cloud services similar to how aws-sdk accesses AWS services. It supports services like Google Cloud Storage, BigQuery, and more. While aws-sdk is specific to AWS, google-cloud is tailored for Google Cloud Platform.

ali-oss

The ali-oss package is an SDK for Alibaba Cloud's OSS (Object Storage Service). It offers a subset of the features provided by aws-sdk, but specifically for Alibaba Cloud's storage service. It's a more specialized tool compared to the broad service coverage of aws-sdk.

README

AWS SDK for JavaScript

The official AWS SDK for JavaScript, available for browsers and mobile devices, or Node.js backends

For release notes, see the CHANGELOG. Prior to v2.4.8, release notes can be found at https://aws.amazon.com/releasenotes/?tag=releasenotes%23keywords%23javascript

If you are upgrading from 1.x to 2.0 of the SDK, please see the upgrading notes for information on how to migrate existing code to work with the new major version.

Installing

In the Browser

To use the SDK in the browser, simply add the following script tag to your HTML pages:

<script src="https://sdk.amazonaws.com/js/aws-sdk-2.712.0.min.js"></script>

You can also build a custom browser SDK with your specified set of AWS services. This can allow you to reduce the SDK's size, specify different API versions of services, or use AWS services that don't currently support CORS if you are working in an environment that does not enforce CORS. To get started:

http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/building-sdk-for-browsers.html

The AWS SDK is also compatible with browserify.

For browser-based web, mobile and hybrid apps, you can use AWS Amplify Library which extends the AWS SDK and provides an easier and declarative interface.

In Node.js

The preferred way to install the AWS SDK for Node.js is to use the npm package manager for Node.js. Simply type the following into a terminal window:

npm install aws-sdk

In React Native

To use the SDK in a react native project, first install the SDK using npm:

npm install aws-sdk

Then within your application, you can reference the react native compatible version of the SDK with the following:

var AWS = require('aws-sdk/dist/aws-sdk-react-native');

Alternatively, you can use AWS Amplify Library which extends AWS SDK and provides React Native UI components and CLI support to work with AWS services.

Using Bower

You can also use Bower to install the SDK by typing the following into a terminal window:

bower install aws-sdk-js

Usage and Getting Started

You can find a getting started guide at:

http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide

API reference at:

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/

Usage with TypeScript

The AWS SDK for JavaScript bundles TypeScript definition files for use in TypeScript projects and to support tools that can read .d.ts files. Our goal is to keep these TypeScript definition files updated with each release for any public api.

Pre-requisites

Before you can begin using these TypeScript definitions with your project, you need to make sure your project meets a few of these requirements:

• Use TypeScript v2.x

• Includes the TypeScript definitions for node. You can use npm to install this by typing the following into a terminal window:

  npm install --save-dev @types/node
  

• If you are targeting at es5 or older ECMA standards, your tsconfig.json has to include 'es5' and 'es2015.promise' under compilerOptions.lib. See tsconfig.json for an example.

In the Browser

To use the TypeScript definition files with the global AWS object in a front-end project, add the following line to the top of your JavaScript file:

/// <reference types="aws-sdk" />

This will provide support for the global AWS object.

In Node.js

To use the TypeScript definition files within a Node.js project, simply import aws-sdk as you normally would.

In a TypeScript file:

// import entire SDK
import AWS from 'aws-sdk';
// import AWS object without services
import AWS from 'aws-sdk/global';
// import individual service
import S3 from 'aws-sdk/clients/s3';

NOTE: You need to add "esModuleInterop": true to compilerOptions of your tsconfig.json. If not possible, use like import * as AWS from 'aws-sdk'.

In a JavaScript file:

// import entire SDK
var AWS = require('aws-sdk');
// import AWS object without services
var AWS = require('aws-sdk/global');
// import individual service
var S3 = require('aws-sdk/clients/s3');

With React

To create React applications with AWS SDK, you can use AWS Amplify Library which provides React components and CLI support to work with AWS services.

With Angular

Due to the SDK's reliance on node.js typings, you may encounter compilation issues when using the typings provided by the SDK in an Angular project created using the Angular CLI.

To resolve these issues, either add "types": ["node"] to the project's tsconfig.app.json file, or remove the "types" field entirely.

AWS Amplify Library provides Angular components and CLI support to work with AWS services.

Known Limitations

There are a few known limitations with the bundled TypeScript definitions at this time:

• Service client typings reflect the latest apiVersion, regardless of which apiVersion is specified when creating a client.
• Service-bound parameters use the any type.

Changelog

2.712.0

• feature: CostExplorer: Customers can now see Instance Name alongside each rightsizing recommendation.
• feature: EC2: EC2 Spot now enables customers to tag their Spot Instances Requests on creation.
• feature: ForecastService: With this release, Amazon Forecast now supports the ability to add a tag to any resource via the launch of three new APIs: TagResouce, UntagResource and ListTagsForResource. A tag is a simple label consisting of a customer-defined key and an optional value allowing for easier resource management.
• feature: Organizations: We have launched a self-service option to make it easier for customers to manage the use of their content by AI services. Certain AI services (Amazon CodeGuru Profiler, Amazon Comprehend, Amazon Lex, Amazon Polly, Amazon Rekognition, Amazon Textract, Amazon Transcribe, and Amazon Translate), may use content to improve the service. Customers have been able to opt out of this use by contacting AWS Support, and now they can opt out on a self-service basis by setting an Organizations policy for all or an individual AI service as listed above. Please refer to the technical documentation for more details.
