react-spring
Physics-based React animation library using spring dynamics instead of traditional duration-based easing. Animations feel natural because spring physics determines timing based on stiffness, friction, and mass parameters. Works with DOM, Three.js (r3f), and React Native. Powers smooth interactive animations and gesture-driven UIs in React applications.

⚙ Agent Friendliness
🔒 Security
Animation library — no network access, no security concerns.
⚡ Reliability
Best When
React applications where natural, physics-based animations and gesture interactions improve UX.
Avoid When
Simple transitions, precise timing requirements, or performance-constrained environments.
Use Cases
- • Animate React component enter/exit with natural spring physics: useSpring for value transitions
- • Create gesture-driven animations with @use-gesture/react and react-spring for drag-responsive UIs
- • Animate lists with automatic transition coordination using useTransition for items entering/leaving
- • Build chain animations where one animation triggers another using useChain API
- • Animate 3D objects in React Three Fiber scenes using @react-spring/three
Not For
- • Simple CSS transitions that can be done with Tailwind CSS or plain CSS
- • Complex timeline-based animations with precise timing control — use GSAP for timeline animations
- • Performance-critical animations on low-end devices — spring calculations have CPU cost vs CSS transitions

Known Gotchas
- ⚠ react-spring v9 changed the API significantly — tutorials using v8's withSpring/interpolate are incompatible; check which version tutorial uses
- ⚠ Spring values must be applied to animated.* elements (animated.div, not regular div) — using regular elements loses animation performance
- ⚠ useSpring hook returns SpringValues, not regular React state — don't destructure for conditional rendering; use to, from, and onChange callbacks
- ⚠ Multiple spring keys update in one call — passing {opacity: 1, transform: 'scale(1)'} animates all properties together with same spring parameters
- ⚠ Cleanup is not automatic for imperative API (SpringRef) — cancel animations with ref.stop() on unmount to prevent state updates on unmounted components
- ⚠ Staggered animations with useSprings require explicit length — the count doesn't auto-adjust when list changes without updating the springs manually
