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:
```jsx
const styles = useSpring({
from: {
opacity: 0
},
to: {
opacity: 1
}
})
```
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
```shell
# Install the entire library
npm install react-spring
# or just install your specific target (recommended)
npm install @react-spring/web
```
```jsx
import { animated, useSpring } from '@react-spring/web'
const FadeIn = ({ isVisible, children }) => {
const styles = useSpring({
opacity: isVisible ? 1 : 0,
y: isVisible ? 0 : 24,
})
return {children}
}
```
It's as simple as that to create scroll-in animations when value of `isVisible` is toggled.
