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
