## What it is
react-cursor is a small JavaScript library providing immutable cursors for managing deeply nested state in React applications, ported from a ClojureScript abstraction. It lets a stateful root component hold all app state while downtree views remain stateless.

## Use cases
- manage immutable nested state in react apps
- hold all react state at the root of the component tree
- make stateless react views with centralized state
- immutable updates on deeply nested javascript data
- efficient react re-renders with value-equality cursors

## When to choose
- you maintain a legacy React codebase already using cursors
- you want a tiny, decoupled immutable state abstraction with a minimal API

## When to avoid
- starting a new React project - modern React has built-in state tools and popular alternatives like Redux or Immer
- you need actively maintained software with ongoing support
- you need a license file or guaranteed legal clarity beyond the npm MIT metadata

## Facets
- artifact type: library
