react-spring

Overview React-spring is a spring-based animation library for React applications. It replaces traditional duration-and-curve animation APIs with spring physics, where animations do not have a defined curve or set duration. The library is built to overcome the limitations of both react-motion (which relies exclusively on React rendering and can be janky) and Popmotion (which skips React rendering entirely). React-spring uses both approaches depending on the context, enabling smooth, fluid interactions. It is written in TypeScript and supports server-side rendering out of the box. Key Benefits Animations run without re-rendering React components, using imperative API methods that bypass the React rendering overhead. Spring-based animations do not require a set duration or predefined curve, matching how motion works in the real world. Fully written in TypeScript for easy integration into existing TypeScript codebases. Production-ready with SSR support — no need for useRef or useEffect to attach animations to DOM nodes. Bundle size is kept small: 55.1 KB for the full react-spring package, 19.2 KB for @react-spring/web, and 15.2 KB for @react-spring/core. Cross-platform support with five targets: web, native (React Native), three (Three.js), konva (Konva), and zdog (Zdog). How It Works You install the library via npm by running npm i @react-spring/web . You import the animated wrapper and a hook such as useSpring , then define animation values with from and to objects. The animated component handles attaching those values to the DOM without requiring refs or effects. Use Cases React UI developers who need drop-in, natural-feeling transitions for modals, drawers, and page elements. Game developers building React-based interfaces who previously found Tailwind CSS animations insufficient for 2020-era expectations. Full-stack teams mixing HTML and WebGL — React-spring can animate both in the same application. Library authors and design system maintainers who want to wrap third-party UI kits (e.g., Reach UI) with custom brand animations. React Native developers seeking a performant cross-platform animation solution that does not trigger re-renders. Creative coders working with Three.js, Konva, or Zdog who want spring physics in their canvas-based projects. Why Choose This Product React-spring is best suited for React developers who want natural, physics-based animations without sacrificing performance or re-render control. The page notes that the learning curve is steeper than expected for some developers, but that the experience becomes delightful afterwards. If you need a target not in the five provided (web, native, three, konva, zdog), you can request it or build one yourself using the advanced API.
