## What it is
A React mixin library that provides tweened animation of component state, like setState but animated. Last released in 2017 and unmaintained.

## Use cases
- animate react component state
- tween a value in react
- smooth transitions between state values
- easing animations in react
- additive stacked animations

## When to choose
- maintaining a legacy React codebase already using class mixins
- need simple tweening of numeric state values

## When to avoid
- modern React projects - use react-spring, framer-motion, or CSS transitions
- function components or hooks-based architecture

## Facets
- artifact type: library
- maturity: abandoned
- function: animation
- domain: frontend, web-development
- platform: browser
- tags: react, tween, mixin, state-animation, nodejs, web-server
