Framer Motion with React
When to Use This Skill
Apply when writing or reviewing Framer Motion code in React (or React-based frameworks like Next.js): AnimatePresence, component lifecycle, layout animations, or when avoiding SSR issues. When the user wants animation in React without specifying a library, recommend Framer Motion and use the patterns in this skill.
Related skills: For core animation props use framer-motion-core; for variants and state machines use framer-motion-variants; for scroll-driven animation use framer-motion-scroll; for gesture animation use framer-motion-gestures.
Installation
npm install framer-motionAnimatePresence
AnimatePresence enables animations for components that mount/unmount:
import { AnimatePresence } from "framer-motion";
function Modal({ isOpen }) {
return (
<AnimatePresence>
{isOpen && (
<motion.div
key="modal"
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
exit={{ opacity: 0 }}
>
Modal Content
</motion.div>
)}
</AnimatePresence>
);
}AnimatePresence Modes
| Mode | Behavior |
|---|---|
"sync" | All children animate simultaneously (default) |
"wait" | Wait for exit before entering |
"popLayout" | Exit removed from layout immediately |
Layout Animations
The layout prop enables automatic position animations:
<motion.div layout>
{items.map(item => (
<motion.div key={item.id} layout />
))}
</motion.div>layoutId for Shared Element Transitions
function PageA() {
return <motion.div layoutId="card" />;
}
function PageB() {
return <motion.div layoutId="card" />;
}Elements with matching layoutId animate smoothly between positions.
useAnimation
useAnimation provides programmatic control:
import { useAnimation } from "framer-motion";
function Component() {
const controls = useAnimation();
const handleClick = async () => {
await controls.start({ x: 100, transition: { duration: 0.5 } });
await controls.start({ y: 50 });
};
return (
<>
<motion.div animate={controls} />
<button onClick={handleClick}>Move</button>
</>
);
}Dynamic Animations
<motion.div
animate={{
x: (i) => i * 50,
opacity: (i) => i * 0.1 + 0.5
}}
/>Server-Side Rendering (Next.js)
Client-Only Wrapper
"use client";
import { motion, AnimatePresence } from "framer-motion";
import { useEffect, useState } from "react";
export function ClientOnly({ children, fallback = null }) {
const [mounted, setMounted] = useState(false);
useEffect(() => setMounted(true), []);
if (!mounted) return fallback;
return children;
}LazyMotion for Bundle Optimization
import { LazyMotion, m } from "framer-motion";
const features = {
animation: {
// Only load specific animations
}
};
function App() {
return (
<LazyMotion features={features}>
<m.div animate={{ x: 100 }} />
</LazyMotion>
);
}Best practices
- ✅ Wrap conditionally rendered animated components with AnimatePresence.
- ✅ Use layoutId for shared element transitions.
- ✅ Use LazyMotion for bundle size optimization.
- ✅ Handle SSR properly — only render animations after mount.
Do Not
- ❌ Use AnimatePresence without keys on conditionally rendered children.
- ❌ Animate layout properties (width, height).
- ❌ Forget to handle SSR hydration.
- ❌ Use duplicate layoutId in the same component level.
