## What it is
A React library that implements spring-physics-based animation, letting developers animate UI elements with stiffness and damping instead of hard-coded easing curves and durations. It provides components like Motion and TransitionMotion for smooth, interruptible animations in React and React Native.

## Use cases
- animate a counter or value with spring physics in React
- create smooth list item enter/exit transitions
- build draggable UI elements with natural motion
- animate chat head or floating UI elements
- create photo gallery and carousel transitions
- replace CSS easing curves with physics-based animation

## When to choose
- you want natural, interruptible spring animations in React
- you need animations that adapt to user interaction rather than fixed durations
- you're maintaining an older React codebase already using react-motion

## When to avoid
- starting a new project - consider modern alternatives like Framer Motion or react-spring
- you need simple CSS transitions without physics
- you need the latest React features and active maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: frontend, web-development
- platform: browser, cross-platform
- tags: react, spring-physics, transitions, react-native, nodejs
