react-spring

A spring-physics first animation library
giving you flexible tools to confidently cast your ideas

react-spring is a cross-platform spring-physics first animation library.

It's as simple as:

const styles = useSpring({
  from: {
    opacity: 0
  },
  to: {
    opacity: 1
  }
})

<animated.div style={styles} />

Just a small bit about us:

• Cross-Platform: We support react-dom, react-native, react-three-fiber, react-konva & react-zdog.
• Versatile: Be declarative with your animations or if you prefer, imperative.
• Spring-Physics First: By default animation use springs for fluid interactivity, but we support durations with easings as well.

There's a lot more to be had! Give it a try and find out.

Getting Started

Jump Start

# Install the entire library
npm install react-spring
# or just install your specific target (recommended)
npm install @react-spring/web

import { animated, useSpring } from '@react-spring/web'

const FadeIn = ({ isVisible, children }) => {
  const styles = useSpring({
    opacity: isVisible ? 1 : 0,
    y: isVisible ? 0 : 24,
  })

  return <animated.div style={styles}>{children}</animated.div>
}

It's as simple as that to create scroll-in animations when value of isVisible is toggled.
