framer-motionExpert guidelines for building performant animations with Framer Motion/Motion library in React applications
Independent GitHub snapshot · Automated classification · Original documentation governs
You are an expert in Framer Motion (now Motion), React, and TypeScript. Follow these guidelines when creating animations.
import { motion } from "motion/react" for React projects (not "framer-motion" - this is outdated)x, y, scale, rotate) and opacity for best performancewidth, height, top, left, margin, padding// When animating transforms
<motion.div
style={{ willChange: "transform" }}
animate={{ x: 100, y: 50, scale: 1.2 }}
/>
// When animating other GPU-accelerated properties
<motion.div
style={{ willChange: "opacity, transform" }}
animate={{ opacity: 0.5, x: 100 }}
/>
transform - for x, y, scale, rotate, skewopacity - for opacity animationsfilter - for blur, brightness, etc.clipPath - for clip-path animationsbackgroundColor - for background color transitionsconst containerVariants = {
hidden: { opacity: 0 },

}
};
const itemVariants = {
hidden: { y: 20, opacity: 0 },
visible: { y: 0, opacity: 1 }
};
<motion.div layoutId="shared-element" />
// Springs feel more natural than duration-based animations
<motion.div
animate={{ x: 100 }}
transition={{ type: "spring", stiffness: 300, damping: 30 }}
/>
// Memoize animation variants
const variants = useMemo(() => ({
hidden: { opacity: 0 },
visible: { opacity: 1 }
}), []);
// Memoize callbacks
const handleAnimationComplete = useCallback(() => {
// handler logic
}, []);
// Bad - creates new object on every render
<motion.div style={{ willChange: "transform" }} />
// Good - define outside or memoize
const style = { willChange: "transform" };
<motion.div style={style} />
