Overview
AWS Amplify JavaScript is a library for using cloud capabilities such as authentication, APIs, and storage from JavaScript and TypeScript web or React Native applications. It exposes integrations for services including Amazon Cognito, S3, and AppSync through category-specific APIs.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Use Auth, API, and Storage through category-specific modules
Applications can import authentication, REST/GraphQL API, and S3 storage operations from dedicated modules and integrate them into frontend code.
Share Amplify configuration across web and React Native workflows
The library targets JavaScript-based web frontends and React Native while using Amplify configuration to connect to AWS backends.
Useful for frontend applications using multiple AWS services
It fits applications that want one client library for workflows such as Cognito authentication, API calls, and S3 file operations.

Supplemental curator note
Amplify JS is the client library used by web and React Native applications; it is not itself the CLI that provisions every backend resource. The current `aws-amplify` package is 6.21.0. The README marks versions v4 and below as deprecated, and their support ended on April 13, 2026, so new implementation should be based on v6.
Try it in 3 steps
- 1
Install Amplify JavaScript v6
Add the current aws-amplify package to a web or React Native project and use v6 as the baseline for new implementation.
npm install aws-amplify - 2
Load backend configuration into Amplify
Load configuration such as amplify_outputs.json generated for the Amplify backend so Auth, API, and Storage can resolve their resources.
import { Amplify } from 'aws-amplify'; Amplify.configure(outputs) - 3
Try one category API
Choose one configured capability such as Auth, API, or Storage and verify the category-specific import and operation against the backend.
import { fetchAuthSession } from 'aws-amplify/auth'
