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. ### 📖 Documentation and Examples More documentation on the project can be found [here](https://www.react-spring.io).
