Opacity Fade Animation — React-motion Code
Animates a div fading in using React Motion.
# react_motion/demo/Fade.jsx
import React from 'react';
import { Motion, spring } from 'react-motion';
function Fade() {
return (
<Motion defaultStyle={{ opacity: 0 }} style={{ opacity: spring(1) }}>
{style => (
<div style={{ width: 100, height: 100, background: 'purple', opacity: style.opacity }} />
)}
</Motion>
);
}

React Motion is a popular animation library for React that uses physics-based animations to create smooth and natural transitions. It provides a simple API to animate components’ styles over time using spring dynamics rather than fixed durations.
Primary Use Cases
- ▸Animating component style changes (e.g., width, height, opacity)
- ▸Enter/exit animations for lists and items
- ▸Sliding panels or modals
- ▸Interactive hover and drag effects
- ▸Smooth state transitions in React apps
Notable Features
- ▸Spring-based animations for natural motion
- ▸Declarative API integrated with React
- ▸Interpolates multiple style values simultaneously
- ▸Supports dynamic updates to animation targets
- ▸Lightweight and composable
Origin & Creator
React Motion was created by Cheng Lou and open-sourced in 2015, becoming widely adopted for physics-based React animations.
Industrial Note
React Motion is used in web apps, dashboards, interactive UIs, and websites where smooth, physics-based motion improves user experience, such as sliding panels, accordions, loaders, and transitions.
