## What it is
Store.js is a JavaScript library providing a simple cross-browser key/value local storage API (get/set/remove/each) with plugin-based storage backends and extra functionality. It has been used in production on tens of thousands of websites since 2010 and supports virtually all browsers.

## Use cases
- persist user settings in the browser across page loads
- store JSON objects in localStorage with a simple API
- support local storage in old browsers like IE6/IE7
- swap storage backends via plugins
- iterate over all stored key/value pairs

## When to choose
- you need cross-browser client-side key/value storage including legacy browsers
- you want a tiny, battle-tested localStorage wrapper with plugin extensibility

## When to avoid
- you only target modern browsers and prefer the native localStorage API directly
- you need server-side or large-scale structured storage like IndexedDB or a database

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, plugin-system
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: localstorage, key-value-storage, cross-browser, client-side-storage, javascript, nodejs
