## What it is
jStorage is a small cross-browser key-value store library for persisting data locally in the browser, supporting strings, numbers, objects, arrays, and XML nodes. It also offers TTL-based key expiration and cross-tab change notifications, effectively acting as a local PubSub mechanism.

## Use cases
- store user preferences in the browser
- cache data locally across page reloads
- persist key-value data in old browsers including IE6
- auto-expire stored keys with TTL
- sync state between browser tabs
- simple client-side pubsub messaging

## When to choose
- you need broad legacy browser support including old IE
- you want a tiny dependency-free key-value storage layer
- you need TTL expiration or cross-tab notifications

## When to avoid
- you only target modern browsers and can use the native localStorage API directly
- you need large-scale or indexed client-side storage like IndexedDB
- you need an actively developed project with new features

## Facets
- artifact type: library
- maturity: maintenance
- function: caching, state-management
- domain: web-development, frontend, browser-extensions
- platform: browser, cross-platform
- tags: local-storage, key-value-store, pubsub, ttl, cross-browser, vanilla-javascript
