The AWS SDK for JavaScript enables you to directly access AWS services from JavaScript code running in the browser. Authenticate users through Facebook, Google, or Login with Amazon using web identity federation. Store application data in Amazon DynamoDB, and save user files to Amazon S3. A single script tag is all you need to start using the SDK.


No Server Required

Direct calls to AWS services mean no server-side code and no need to configure application servers.

Simple to Deploy

Since there's no application logic to be processed on the server side, deploying your web application can be as easy as uploading it to an Amazon S3 bucket.

Easy to Learn

Using nothing but common web standards - HTML, CSS, and JavaScript - you can build full-featured dynamic browser applications.


Social Login

Secure your browser app access to AWS resources without any server-side code. AWS SDK for JavaScript makes it easy for you to integrate with Amazon Cognito or AWS IAM's web identity federation, so that you can provide API access to users authenticated through identity providers like Facebook, Google, or Login with Amazon.

Online Data

Deliver a connected browser application experience using data in the cloud. Amazon DynamoDB is a fast, fully managed NoSQL database service that makes it simple and cost-effective to store and retrieve your app data. Fine-grained access control securely isolates user data within a single DynamoDB table and enables private data storage directly from a browser app.

File Storage

Securely store and access unlimited amounts of user files with Amazon S3. The AWS SDK for JavaScript integrates with the browser's native file interface to simplify uploading to Amazon S3.
