## What it is
A tiny promise-based key-value store library built on top of IndexedDB for browsers. It offers a minimal get/set/del API in under 600 bytes, storing any structured-clonable value.

## Use cases
- store data in the browser without localStorage limits
- persist blobs and structured objects client-side
- simple offline storage for a web app
- replace localStorage with async promise-based storage
- cache API responses in the browser

## When to choose
- you need a tiny, tree-shakeable IndexedDB wrapper with a simple keyval API
- you want to store structured-clonable values like Blobs and Dates
- your target browsers have working IndexedDB support

## When to avoid
- you need indexes, iteration, or complex queries - use the idb library instead
- you must support old browsers with broken IndexedDB - use localForage
- you need a full database with relations or SQL

## Facets
- artifact type: library
- maturity: stable
- function: database, caching
- domain: web-development, frontend, databases
- platform: browser
- tags: indexeddb, key-value-store, promise-based, localstorage-alternative, tree-shakeable, typescript, javascript, nodejs
