## What it is
A small JavaScript library that emulates memcache-style caching using HTML5 localStorage, with per-item expiration times and automatic eviction of soonest-expiring items when the ~5MB limit is reached. It gracefully degrades to a no-op cache when localStorage is unavailable.

## Use cases
- cache API responses in the browser with expiration
- store data client-side with a TTL
- emulate memcache in localStorage
- partition cached data into buckets
- evict expired cache entries automatically
- check if localStorage is supported before caching

## When to choose
- you need simple client-side caching with expiration in a browser app
- you want a memcache-like API backed by localStorage
- you need graceful fallback when localStorage is unavailable

## When to avoid
- you need caching in Node.js or non-browser environments
- you need more than ~5MB of storage
- you need a modern async cache like IndexedDB or Cache API

## Facets
- artifact type: library
- maturity: maintenance
- function: caching
- domain: web-development, frontend, developer-tools
- platform: browser
