Motion for React

Package:

motion

(formerly

framer-motion

). Import from

"motion/react"

Installation

bash

pnpm add motion

Imports

tsx

// Standard React (Vite, CRA, Pages Router)
import { motion, AnimatePresence } from "motion/react"

// Next.js App Router — use "motion/react-client" for RSC tree-shaking
"use client"
import * as motion from "motion/react-client"

// Minimal bundle (2.3 KB) — imperative API only
import { useAnimate } from "motion/react-mini"

// Reduced bundle (4.6 KB) — LazyMotion + m component
import { LazyMotion, domAnimation, m } from "motion/react"

Motion Component

Every HTML/SVG element has a

motion

counterpart:

tsx

<motion.div />
<motion.button />
<motion.svg />
<motion.circle />

Custom components: wrap with

motion.create()

tsx

const MotionBox = motion.create(Box)
// forwardRef required — the ref must reach a DOM node

Core Animation Props

tsx

<motion.div
  initial={{ opacity: 0, y: 20 }}     // mount state (or false to skip)
  animate={{ opacity: 1, y: 0 }}      // target state
  exit={{ opacity: 0, y: -20 }}       // unmount state (needs AnimatePresence)
  transition={{ type: "spring", bounce: 0.25 }}
  whileHover={{ scale: 1.05 }}
  whileTap={{ scale: 0.95 }}
  whileFocus={{ borderColor: "#00f" }}
  whileDrag={{ scale: 1.1 }}
  whileInView={{ opacity: 1 }}
  viewport={{ once: true, margin: "-100px" }}
/>

Animatable Values

Motion animates any CSS value:

opacity

filter

background-image

mask-image

Independent transforms (not possible in CSS alone):

Translate:
```
x
```
,
```
y
```
,
```
z
```
Scale:
```
scale
```
,
```
scaleX
```
,
```
scaleY
```
Rotate:
```
rotate
```
,
```
rotateX
```
,
```
rotateY
```
,
```
rotateZ
```
Skew:
```
skewX
```
,
```
skewY
```
Origin:
```
originX
```
,
```
originY
```
,
```
originZ
```

Value types: numbers, strings with units (

"100px"

), colors (hex/rgba/hsla),

"auto"

for width/height.

Hardware acceleration: set

transform

directly for GPU compositing:

tsx

<motion.li
  initial={{ transform: "translateX(-100px)" }}
  animate={{ transform: "translateX(0px)" }}
  transition={{ type: "spring" }}
/>

Keyframes

Pass arrays to animate through a sequence:

tsx

<motion.div animate={{ x: [0, 100, 0] }} />

// null = "use current value"
<motion.div animate={{ x: [null, 100, 0] }} />

Variants

Named animation states for orchestrated animations:

tsx

const list = {
  visible: {
    transition: { staggerChildren: 0.1 }
  },
  hidden: {}
}

const item = {
  visible: { opacity: 1, y: 0 },
  hidden: { opacity: 0, y: 20 }
}

<motion.ul initial="hidden" animate="visible" variants={list}>
  <motion.li variants={item} />
  <motion.li variants={item} />
</motion.ul>

Variants propagate through the tree. Children inherit

animate

initial

exit

from parent.

AnimatePresence — Exit Animations

tsx

import { AnimatePresence } from "motion/react"

<AnimatePresence>
  {isVisible && (
    <motion.div
      key="modal"           // REQUIRED: unique key
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
      exit={{ opacity: 0 }}
    />
  )}
</AnimatePresence>

Critical rules:

AnimatePresence must stay mounted — never wrap it in a conditional
Direct children must have unique
key
props
```
exit
```
prop only works on
```
motion
```
components inside AnimatePresence

tsx

// WRONG — AnimatePresence unmounts with condition
{show && <AnimatePresence><motion.div /></AnimatePresence>}

// CORRECT — condition inside AnimatePresence
<AnimatePresence>{show && <motion.div key="k" />}</AnimatePresence>

Modes:

"sync"

(default),

"wait"

(sequential enter/exit),

"popLayout"

(pop exiting element out of flow).

Slideshow pattern — change

key

to trigger exit+enter:

tsx

<AnimatePresence mode="wait">
  <motion.img
    key={image.src}
    initial={{ x: 300, opacity: 0 }}
    animate={{ x: 0, opacity: 1 }}
    exit={{ x: -300, opacity: 0 }}
  />
</AnimatePresence>

Dynamic exit data — pass via

custom

prop +

usePresenceData

tsx

<AnimatePresence custom={direction}>
  <Slide key={id} />
</AnimatePresence>

// Inside Slide:
const direction = usePresenceData()

Transitions

For full transition API details, see references/transitions-api.md.

Quick reference:

tsx

// Spring (default for physical props: x, y, scale)
transition={{ type: "spring", bounce: 0.25 }}
transition={{ type: "spring", stiffness: 300, damping: 20 }}
transition={{ type: "spring", visualDuration: 0.5, bounce: 0.25 }}

// Tween (default for opacity, color)
transition={{ duration: 0.3, ease: "easeInOut" }}

// Per-value transitions
transition={{
  default: { type: "spring" },
  opacity: { duration: 0.2, ease: "linear" }
}}

// Orchestration
transition={{ delay: 0.5, repeat: Infinity, repeatType: "reverse" }}

// Global default
<MotionConfig transition={{ duration: 0.3 }}>

Layout Animations

For full layout animation details, see references/layout-animations.md.

tsx

// Auto-animate any layout change
<motion.div layout />

// Shared element transitions
<motion.div layoutId="underline" />

// Customize layout transition
<motion.div layout transition={{ layout: { duration: 0.3 } }} />

Gestures & Drag

For full gesture/drag API, see references/gestures-and-drag.md.

tsx

<motion.div
  whileHover={{ scale: 1.1 }}
  whileTap={{ scale: 0.9 }}
  drag                           // enable both axes
  drag="x"                       // constrain to x-axis
  dragConstraints={{ left: -100, right: 100 }}
  dragElastic={0.2}
/>

Scroll Animations

For full scroll API, see references/scroll-animations.md.

tsx

// Viewport-triggered
<motion.div
  initial={{ opacity: 0, y: 50 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true }}
/>

// Scroll-linked progress bar
const { scrollYProgress } = useScroll()
<motion.div style={{ scaleX: scrollYProgress }} />

// Element scroll progress
const ref = useRef(null)
const { scrollYProgress } = useScroll({
  target: ref,
  offset: ["start end", "end start"]
})

Hooks & Motion Values

For full hooks API, see references/hooks-and-motion-values.md.

tsx

// Manual motion values (no re-renders)
const x = useMotionValue(0)
const opacity = useTransform(x, [-200, 0, 200], [0, 1, 0])
<motion.div drag="x" style={{ x, opacity }} />

// Smooth spring following
const springX = useSpring(x, { stiffness: 100, damping: 30 })

// Imperative animation control
const [scope, animate] = useAnimate()
animate("li", { opacity: 1 }, { stagger: 0.1 })

// Event listener (no re-render)
useMotionValueEvent(scrollY, "change", (v) => console.log(v))

Bundle Optimization

Approach	Size	What you get
`motion/react`	~34 KB	Full API
`LazyMotion` + `m`	~4.6 KB	Declarative animations, no gestures
`motion/react-mini`	~2.3 KB	`useAnimate` only

tsx

// LazyMotion pattern
import { LazyMotion, domAnimation, m } from "motion/react"

<LazyMotion features={domAnimation}>
  <m.div animate={{ opacity: 1 }} />
</LazyMotion>

Accessibility

tsx

<MotionConfig reducedMotion="user">
  <App />
</MotionConfig>

Options:

"user"

(respect OS setting),

"always"

(force instant),

"never"

(ignore).

Hook:

useReducedMotion()

returns

true

when user prefers reduced motion.

Tailwind Integration

Let each library handle its strength. Remove Tailwind
transition-*
classes — they conflict.

tsx

// WRONG — Tailwind transition conflicts with Motion
<motion.div className="transition-all duration-300" animate={{ x: 100 }} />

// CORRECT — Tailwind for styling, Motion for animation
<motion.div className="rounded-lg bg-blue-600 p-4" whileHover={{ scale: 1.05 }} />

Next.js App Router

Motion components require client-side rendering. Use

"motion/react-client"

for optimal tree-shaking:

tsx

// components/motion-client.tsx
"use client"
import * as motion from "motion/react-client"
export { motion }

// app/page.tsx (Server Component)
import { motion } from "@/components/motion-client"
<motion.div animate={{ opacity: 1 }} />

Common Pitfalls

Exit animations not firing — AnimatePresence must stay mounted; children need unique
```
key
```
Tailwind transition conflict — Remove
```
transition-*
```
classes from motion elements

height: "auto"
+
display: "none"
— Use

visibility: "hidden"

instead

Layout animations in scrollable containers — Add
```
layoutScroll
```
prop to scroll parent
Layout animations in fixed elements — Add
```
layoutRoot
```
prop to fixed parent
Percentage transforms + layout — Convert to pixels; percentage values break FLIP calculation
popLayout
mode — Custom components must use
```
forwardRef
```
to forward ref to DOM node
AnimatePresence
propagate
— Set to
```
true
```
on nested AnimatePresence to fire child exits
