## What it is
AmplifyJS is a jQuery-era JavaScript component library providing three modules: a pub/sub message bus for component communication, a unified client-side storage wrapper over localStorage/sessionStorage with fallbacks, and an AJAX request abstraction with caching and data transformation. It was produced by appendTo and is dual-licensed under MIT and GPL-2.0.

## Use cases
- decouple frontend components with publish/subscribe messaging
- wrap localStorage and sessionStorage behind one simple API
- abstract and cache AJAX data requests in a jQuery app
- manage a centralized server interface definition for client data access
- store data client-side that works across desktop and mobile browsers

## When to choose
- maintaining a legacy jQuery-based web application already using AmplifyJS
- you need a tiny, dependency-free pub/sub and storage shim for old browsers

## When to avoid
- starting a new modern frontend project - use native fetch, localStorage, and an event emitter or state library instead
- you need actively maintained code with security updates - the project has had no meaningful development since ~2012
- you use frameworks like React or Vue with their own state and data-fetching ecosystems

## Facets
