Cloudflare Workers 注意事项:
# 两个包现在都可以与 Cloudflare Workers 配合使用(issue #2918 已于 2024年12月修复)
pnpm add motion
# 或者
pnpm add framer-motion # 相同版本,相同 API
motion 组件:约 34 KB(压缩+gzip)LazyMotion + m 组件:约 4.6 KBuseAnimate mini:2.3 KB(最小的 React 动画库)useAnimate hybrid:17 KB在组件卸载时启用动画:
import { AnimatePresence } from "motion/react"
<AnimatePresence>
{isVisible && (
<motion.div
key="modal"
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
exit={{ opacity: 0 }}
>
模态内容
</motion.div>
)}
</AnimatePresence>
关键规则:
key属性常见错误(退出动画不会播放):
// ❌ 错误 - AnimatePresence 随条件语句一起卸载
{isVisible && (
<AnimatePresence>
<motion.div>内容</motion.div>
</AnimatePresence>
)}
// ✅ 正确 - AnimatePresence 保持挂载
<AnimatePresence>
{isVisible && <motion.div key="unique">内容</motion.div>}
</AnimatePresence>
特殊属性:
layout:启用 FLIP 布局动画
layoutId:连接独立的元素以实现共享过渡
layoutScroll:修复可滚动容器中的动画(参见 Issue #5)
layoutRoot:修复固定定位元素中的动画(参见 Issue #7)
<motion.div layout> {isExpanded ? <FullContent /> : <Summary />} </motion.div>
<motion.div
initial={{ opacity: 0, y: 50 }}
whileInView={{ opacity: 1, y: 0 }}
viewport={{ once: true, margin: "-100px" }}
>
在距离进入视口 100px 时淡入
</motion.div>
import { useScroll, useTransform } from "motion/react"
const { scrollYProgress } = useScroll()
const y = useTransform(scrollYProgress, [0, 1], [0, -300])
<motion.div style={{ y }}>
随着用户滚动页面向上移动 300px
</motion.div>
性能:在可用时使用原生 ScrollTimeline API 进行硬件加速。
pnpm add motion
导入:import { motion } from "motion/react"
无需 Vite 配置 - 开箱即用。
关键要求:Motion 仅适用于客户端组件(不适用于服务器组件)。
步骤 1:创建客户端组件包装器
src/components/motion-client.tsx:
"use client"
// 针对 Next.js 的优化导入(减少客户端 JS)
import * as motion from "motion/react-client"
export { motion }
步骤 2:在服务器组件中使用
src/app/page.tsx:
import { motion } from "@/components/motion-client"
export default function Page() {
return (
<motion.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
>
这在服务器组件中有效(包装器是客户端组件)
</motion.div>
)
}
替代方案:直接客户端组件
"use client"
import { motion } from "motion/react"
export function AnimatedCard() {
return <motion.div>...</motion.div>
}
已知问题(Next.js 15+ + React 19):
无需修改即可工作:
import { motion } from "motion/react"
export default function Page() {
return <motion.div>无需 "use client"</motion.div>
}
最佳实践:让每个库各司其职。
Tailwind:通过 className 进行静态和响应式样式设计
Motion:通过 motion 属性进行动画
<motion.button className="bg-blue-600 text-white px-4 py-2 rounded hover:bg-blue-700" whileHover={{ scale: 1.1 }} whileTap={{ scale: 0.95 }}
Tailwind 样式 + Motion 动画 </motion.button>
⚠️ 移除 Tailwind 过渡:会导致卡顿/冲突。
// ❌ 错误 - Tailwind 过渡与 Motion 冲突
<motion.div className="transition-all duration-300" animate={{ x: 100 }} />
// ✅ 正确 - 移除 Tailwind 过渡
<motion.div animate={{ x: 100 }} />
原因:Motion 使用内联样式或原生浏览器动画,两者都会覆盖 Tailwind 的 CSS 过渡。
状态:✅ 自 2024 年 12 月起已修复(GitHub issue #2918 已关闭并标记为完成)
安装:
# Motion 现在可以直接与 Cloudflare Workers 配合使用
pnpm add motion
导入:
import { motion } from "motion/react"
历史说明:在 2024 年 12 月之前,存在一个 Wrangler ESM 解析问题,需要使用 framer-motion 作为变通方法。此问题已解决,现在两个包都可以与 Cloudflare Workers 正常工作。
问题:完整的 motion 组件约 34 KB(压缩+gzip)。
解决方案:使用 LazyMotion + m 组件,大小约 4.6 KB:
import { LazyMotion, domAnimation, m } from "motion/react"
function App() {
return (
<LazyMotion features={domAnimation}>
{/* 使用 'm' 而不是 'motion' */}
<m.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
>
仅 4.6 KB!
</m.div>
</LazyMotion>
)
}
工作原理:按需加载动画功能,而不是打包所有内容。
替代方案(最小):useAnimate mini(2.3 KB):
import { useAnimate } from "motion/react"
function Component() {
const [scope, animate] = useAnimate()
return <div ref={scope}>最小的 React 动画</div>
}
为变换添加willChange:
<motion.div
style={{ willChange: "transform" }}
animate={{ x: 100, rotate: 45 }}
/>
同样适用于:opacity、backgroundColor、clipPath、filter
工作原理:告诉浏览器优化动画,使用 GPU 合成。
问题:动画 50-100 个以上的项目会导致严重减速。
解决方案:
pnpm add react-window
# 或者
pnpm add react-virtuoso
# 或者
pnpm add @tanstack/react-virtual
模式:
import { FixedSizeList } from 'react-window'
import { motion } from 'motion/react'
<FixedSizeList
height={600}
itemCount={1000}
itemSize={50}
>
{({ index, style }) => (
<motion.div style={style} layout>
项目 {index}
</motion.div>
)}
</FixedSizeList>
原因:仅渲染可见项目,减少 DOM 更新和内存使用。
layout 属性进行 FLIP 动画无需 JavaScript 计算即可自动动画化布局变化:
<motion.div layout>
{isExpanded ? <LargeContent /> : <SmallContent />}
</motion.div>
性能:通过变换进行硬件加速,无需回流/重绘。
prefers-reduced-motionimport { MotionConfig } from "motion/react"
<MotionConfig reducedMotion="user">
<App />
</MotionConfig>
选项:
"user":尊重操作系统设置(推荐)"always":强制即时过渡"never":忽略用户偏好注意:✅ 已于 2023 年 1 月修复(GitHub #1567)- MotionConfig 现在可以与 AnimatePresence 正常工作。

错误:退出动画不播放,组件立即消失 来源:GitHub Issue #3078
发生原因:AnimatePresence 包裹在条件语句中或缺少 key 属性。在模态框内的交错子元素上定义 exit 属性也可能阻止模态框卸载(背景保持可见)。
解决方案:
// ❌ 错误 - AnimatePresence 包裹在条件语句中
{isVisible && (
<AnimatePresence>
<motion.div>内容</motion.div>
</AnimatePresence>
)}
// ✅ 正确 - AnimatePresence 保持挂载
<AnimatePresence>
{isVisible && <motion.div key="unique">内容</motion.div>}
</AnimatePresence>
// ❌ 错误 - 带有退出动画的交错子元素阻止模态框移除
<AnimatePresence>
{isOpen && (
<Modal>
<motion.ul>
{items.map(item => (
<motion.li
key={item.id}
exit={{ opacity: 1, scale: 1 }} // ← 阻止模态框卸载
>
{item.content}
</motion.li>
))}
</motion.ul>
</Modal>
)}
</AnimatePresence>
// ✅ 模态框修复 - 从子元素移除退出动画或设置 duration: 0
<motion.li
key={item.id}
exit={{ opacity: 0, scale: 0.5, transition: { duration: 0 } }}
>
{item.content}
</motion.li>
症状:50-100 个以上的动画项目导致严重减速,浏览器卡顿。
解决方案:使用虚拟化:
pnpm add react-window
完整指南请参见 references/performance-optimization.md。
症状:动画卡顿或不工作。
解决方案:移除 transition-* 类:
// ❌ 错误
<motion.div className="transition-all" animate={{ x: 100 }} />
// ✅ 正确
<motion.div animate={{ x: 100 }} />
症状:构建失败,提示 "motion is not defined" 或 SSR 错误。
解决方案:添加 "use client" 指令:
"use client"
import { motion } from "motion/react"
App Router 模式请参见 references/nextjs-integration.md。
症状:从已滚动的容器中移除项目时过渡不完整。
解决方案:添加 layoutScroll 属性:
<motion.div layoutScroll className="overflow-auto">
{items.map(item => (
<motion.div key={item.id} layout>
{item.content}
</motion.div>
))}
</motion.div>
状态:✅ 已于 2024 年 12 月修复(GitHub issue #2918 已关闭并标记为完成)
先前症状:使用 motion 包时,Wrangler 构建因 React 导入错误而失败。
当前状态:Motion 现在可以与 Cloudflare Workers 正常工作。无需变通方法。
如果遇到构建问题:确保使用 Motion v12.23.24 或更高版本以及 Wrangler v3+。
GitHub issue:#2918(已于 2024 年 12 月 13 日关闭并标记为完成)
症状:固定元素中的布局动画定位不正确。
解决方案:添加 layoutRoot 属性:
<motion.div layoutRoot className="fixed top-0 left-0">
<motion.div layout>内容</motion.div>
</motion.div>
症状:AnimatePresence 内带有 layoutId 的元素无法卸载。
解决方案:包裹在 LayoutGroup 中或避免混合退出和布局动画:
import { LayoutGroup } from "motion/react"
<LayoutGroup>
<AnimatePresence>
{items.map(item => (
<motion.div key={item.id} layoutId={item.id}>
{item.content}
</motion.div>
))}
</AnimatePresence>
</LayoutGroup>
状态:✅ 已于 2023 年 1 月修复(GitHub issue #1567 已通过 PR #1891 关闭)
先前症状:MotionConfig 的 reducedMotion 设置不影响 AnimatePresence 动画。
当前状态:MotionConfig 现在正确地将 reducedMotion 应用于 AnimatePresence 组件。该设置按文档所述工作。
可选手动控制:如果需要超出内置支持的自定义行为:
const prefersReducedMotion = window.matchMedia("(prefers-reduced-motion: reduce)").matches
<motion.div
initial={{ opacity: prefersReducedMotion ? 1 : 0 }}
animate={{ opacity: 1 }}
transition={{ duration: prefersReducedMotion ? 0 : 0.3 }}
/>
GitHub issue:#1567(已于 2023 年 1 月 13 日关闭并标记为完成)
错误:Reorder 自动滚动失败,与 Next.js 路由不兼容 来源:GitHub Issue #3469、#2183、#2101
发生原因:
Reorder.Group 位于具有 overflow: auto/scroll 的元素内时有效,而不是当文档本身可滚动时预防措施:
// ❌ 错误 - 页面级滚动(自动滚动失败)
<body style={{ height: "200vh" }}>
<Reorder.Group values={items} onReorder={setItems}>
{/* 在视口边缘不会触发自动滚动 */}
</Reorder.Group>
</body>
// ✅ 正确 - 带有 overflow 的容器
<div style={{ height: "300px", overflow: "auto" }}>
<Reorder.Group values={items} onReorder={setItems}>
{items.map(item => (
<Reorder.Item key={item.id} value={item}>
{item.content}
</Reorder.Item>
))}
</Reorder.Group>
</div>
// ✅ 替代方案 - 对于复杂情况使用 DnD Kit
// Motion 文档官方推荐 DnD Kit 用于:
// - 多行重新排序
// - 列间拖拽
// - 页面级可滚动容器
// - 复杂的拖放交互
// 安装:pnpm add @dnd-kit/core @dnd-kit/sortable @dnd-kit/utilities
完整的 Next.js 故障排除指南请参见 references/nextjs-integration.md。
错误:在文件树中从上到下拖拽时拖拽手势中断 来源:GitHub Issue #3169
发生原因:仅在使用 React 19 + 启用 StrictMode + Ant Design 组件时发生。拖拽元素位置中断并显示偏移。在 React 18 或未启用 StrictMode 的 React 19 中不会发生。仅影响从上到下的拖拽(从下到上正常工作)。
预防措施:对于使用拖拽手势的 React 19 项目,暂时禁用 StrictMode,或者如果 StrictMode 至关重要,则使用 React 18。等待 Motion 团队的官方修复。
错误:在缩放的父容器中,布局动画从错误的位置开始 来源:GitHub Issue #3356
发生原因:布局动画系统使用缩放后的坐标,就好像它们未缩放一样。Motion 的布局动画以像素为单位工作,而父级缩放会影响视觉坐标。这种不匹配导致位置计算错误。
预防措施(社区变通方法):
// 使用 transformTemplate 来纠正父级缩放
const scale = 2; // 父级的变换缩放值
<div style={{ transform: `scale(${scale})` }}>
<motion.div
layout
transformTemplate={(latest, generated) => {
const match = /translate3d\((.+)px,\s?(.+)px,\s?(.+)px\)/.exec(generated);
if (match) {
const [, x, y, z] = match;
return `translate3d(${Number(x) / scale}px, ${Number(y) / scale}px, ${Number(z) / scale}px)`;
}
return generated;
}}
>
内容
</motion.div>
</div>
限制:仅适用于布局动画,不修复其他变换,需要知道父级缩放值。
错误:当子组件在退出动画触发后立即卸载时,退出状态卡住 来源:GitHub Issue #3243
发生原因:当 AnimatePresence 内的子组件在退出动画触发后立即卸载时,退出状态会卡住。组件错误地保持在"退出"状态。
预防措施:在 AnimatePresence 处理退出动画时,不要卸载 motion 组件。确保 motion.div 保持挂载直到退出完成。仅在父级 AnimatePresence 子元素上使用条件渲染。
错误:布局动画瞬间传送而不是平滑动画 来源:GitHub Issue #3401
发生原因:在 initial 属性中使用基于百分比的 x 值会破坏布局动画,当容器使用 display flex 并带有 justify-content center 时。Motion 的布局动画以像素为单位工作,而 CSS 百分比变换是相对于元素/父级解析的。坐标系不匹配导致位置在帧中重新计算。
预防措施:在动画前将百分比转换为像素。计算容器宽度并使用像素值而不是百分比字符串。
错误:在退出过渡开始前出现 1px 布局偏移 来源:GitHub Issue #3260
发生原因:当使用带有 popLayout 模式的 AnimatePresence 时,退出元素的尺寸被捕获并重新应用为内联样式。来自 getBoundingClientRect 的亚像素值被四舍五入到最近的整数,导致可见的布局偏移。可能导致文本换行变化。
预防措施:仅对尺寸使用整数像素值,或避免对亚像素敏感布局使用 popLayout。不存在完美的变通方法。

Motion (package: motion, formerly framer-motion) is the industry-standard React animation library used in production by thousands of applications. With 30,200+ GitHub stars and 300+ official examples, it provides a declarative API for creating sophisticated animations with minimal code.
Key Capabilities:
Production Tested : React 19.2, Next.js 16.1, Vite 7.3, Tailwind v4
Complex Interactions :
Scroll-Based Animations :
Layout Transitions :
Advanced Features :
Bundle Optimization :
Simple List Animations → Use auto-animate skill instead:
Static Content :
Cloudflare Workers Deployment → ✅ Fixed (Dec 2024) :
motion and framer-motion v12.23.24 work correctly3D Animations → Use dedicated 3D library:
# Using pnpm (recommended)
pnpm add motion
# Using npm
npm install motion
# Using yarn
yarn add motion
Current Version : 12.27.5 (verified 2026-01-21)
Note for Cloudflare Workers :
# Both packages work with Cloudflare Workers (issue #2918 fixed Dec 2024)
pnpm add motion
# OR
pnpm add framer-motion # Same version, same API
motion component: ~34 KB minified+gzippedLazyMotion + m component: ~4.6 KBuseAnimate mini: 2.3 KB (smallest React animation library)useAnimate hybrid: 17 KBEnables animations when components unmount:
import { AnimatePresence } from "motion/react"
<AnimatePresence>
{isVisible && (
<motion.div
key="modal"
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
exit={{ opacity: 0 }}
>
Modal content
</motion.div>
)}
</AnimatePresence>
Critical Rules:
key propsCommon Mistake (exit animation won't play):
// ❌ Wrong - AnimatePresence unmounts with condition
{isVisible && (
<AnimatePresence>
<motion.div>Content</motion.div>
</AnimatePresence>
)}
// ✅ Correct - AnimatePresence stays mounted
<AnimatePresence>
{isVisible && <motion.div key="unique">Content</motion.div>}
</AnimatePresence>
Special Props:
layout: Enable FLIP layout animations
layoutId: Connect separate elements for shared transitions
layoutScroll: Fix animations in scrollable containers (see Issue #5)
layoutRoot: Fix animations in fixed-position elements (see Issue #7)
<motion.div layout> {isExpanded ? <FullContent /> : <Summary />} </motion.div>
<motion.div
initial={{ opacity: 0, y: 50 }}
whileInView={{ opacity: 1, y: 0 }}
viewport={{ once: true, margin: "-100px" }}
>
Fades in when 100px from entering viewport
</motion.div>
import { useScroll, useTransform } from "motion/react"
const { scrollYProgress } = useScroll()
const y = useTransform(scrollYProgress, [0, 1], [0, -300])
<motion.div style={{ y }}>
Moves up 300px as user scrolls page
</motion.div>
Performance : Uses native ScrollTimeline API when available for hardware acceleration.
pnpm add motion
Import: import { motion } from "motion/react"
No Vite configuration needed - works out of the box.
Key Requirement : Motion only works in Client Components (not Server Components).
Step 1: Create Client Component Wrapper
src/components/motion-client.tsx:
"use client"
// Optimized import for Next.js (reduces client JS)
import * as motion from "motion/react-client"
export { motion }
Step 2: Use in Server Components
src/app/page.tsx:
import { motion } from "@/components/motion-client"
export default function Page() {
return (
<motion.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
>
This works in Server Component (wrapper is client)
</motion.div>
)
}
Alternative: Direct Client Component
"use client"
import { motion } from "motion/react"
export function AnimatedCard() {
return <motion.div>...</motion.div>
}
Known Issues (Next.js 15+ + React 19) :
Works without modifications:
import { motion } from "motion/react"
export default function Page() {
return <motion.div>No "use client" needed</motion.div>
}
Best Practice : Let each library do what it does best.
Tailwind : Static and responsive styling via className
Motion : Animations via motion props
<motion.button className="bg-blue-600 text-white px-4 py-2 rounded hover:bg-blue-700" whileHover={{ scale: 1.1 }} whileTap={{ scale: 0.95 }}
Tailwind styles + Motion animations </motion.button>
⚠️ Remove Tailwind Transitions : Causes stuttering/conflicts.
// ❌ Wrong - Tailwind transition conflicts with Motion
<motion.div className="transition-all duration-300" animate={{ x: 100 }} />
// ✅ Correct - Remove Tailwind transition
<motion.div animate={{ x: 100 }} />
Why : Motion uses inline styles or native browser animations, both override Tailwind's CSS transitions.
Status : ✅ Fixed as of December 2024 (GitHub issue #2918 closed as completed)
Installation :
# Motion now works directly with Cloudflare Workers
pnpm add motion
Import:
import { motion } from "motion/react"
Historical Note : Prior to December 2024, there was a Wrangler ESM resolution issue requiring use of framer-motion as a workaround. This has been resolved, and both packages now work correctly with Cloudflare Workers.
Problem : Full motion component is ~34 KB minified+gzipped.
Solution : Use LazyMotion + m component for 4.6 KB:
import { LazyMotion, domAnimation, m } from "motion/react"
function App() {
return (
<LazyMotion features={domAnimation}>
{/* Use 'm' instead of 'motion' */}
<m.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
>
Only 4.6 KB!
</m.div>
</LazyMotion>
)
}
How it works : Loads animation features on-demand instead of bundling everything.
Alternative (Smallest) : useAnimate mini (2.3 KB):
import { useAnimate } from "motion/react"
function Component() {
const [scope, animate] = useAnimate()
return <div ref={scope}>Smallest possible React animation</div>
}
AddwillChange for transforms:
<motion.div
style={{ willChange: "transform" }}
animate={{ x: 100, rotate: 45 }}
/>
Also add for : opacity, backgroundColor, clipPath, filter
How it works : Tells browser to optimize for animation, uses GPU compositing.
Problem : Animating 50-100+ items causes severe slowdown.
Solutions:
pnpm add react-window
# or
pnpm add react-virtuoso
# or
pnpm add @tanstack/react-virtual
Pattern:
import { FixedSizeList } from 'react-window'
import { motion } from 'motion/react'
<FixedSizeList
height={600}
itemCount={1000}
itemSize={50}
>
{({ index, style }) => (
<motion.div style={style} layout>
Item {index}
</motion.div>
)}
</FixedSizeList>
Why : Only renders visible items, reduces DOM updates and memory usage.
layout Prop for FLIP AnimationsAutomatically animates layout changes without JavaScript calculation:
<motion.div layout>
{isExpanded ? <LargeContent /> : <SmallContent />}
</motion.div>
Performance : Hardware-accelerated via transforms, no reflow/repaint.
prefers-reduced-motionimport { MotionConfig } from "motion/react"
<MotionConfig reducedMotion="user">
<App />
</MotionConfig>
Options:
"user": Respects OS setting (recommended)"always": Force instant transitions"never": Ignore user preferenceNote : ✅ Fixed in Jan 2023 (GitHub #1567) - MotionConfig now works correctly with AnimatePresence.
5 Production-Ready Patterns:
height: "auto"drag="x" with dragConstraintswhileInView with viewport marginuseScroll + useTransform for layered effectsSee references/common-patterns.md for full code (15+ patterns).
Error : Exit animations don't play, components disappear instantly Source : GitHub Issue #3078
Why It Happens : AnimatePresence wrapped in conditional or missing key props. Defining exit props on staggered children inside modals can also prevent modal from unmounting (backdrop remains visible).
Solution :
// ❌ Wrong - AnimatePresence wrapped in conditional
{isVisible && (
<AnimatePresence>
<motion.div>Content</motion.div>
</AnimatePresence>
)}
// ✅ Correct - AnimatePresence stays mounted
<AnimatePresence>
{isVisible && <motion.div key="unique">Content</motion.div>}
</AnimatePresence>
// ❌ Wrong - Staggered children with exit prevent modal removal
<AnimatePresence>
{isOpen && (
<Modal>
<motion.ul>
{items.map(item => (
<motion.li
key={item.id}
exit={{ opacity: 1, scale: 1 }} // ← Prevents modal unmount
>
{item.content}
</motion.li>
))}
</motion.ul>
</Modal>
)}
</AnimatePresence>
// ✅ Fix for modal - Remove exit from children or set duration: 0
<motion.li
key={item.id}
exit={{ opacity: 0, scale: 0.5, transition: { duration: 0 } }}
>
{item.content}
</motion.li>
Symptom : 50-100+ animated items cause severe slowdown, browser freezes.
Solution : Use virtualization:
pnpm add react-window
See references/performance-optimization.md for full guide.
Symptom : Animations stutter or don't work.
Solution : Remove transition-* classes:
// ❌ Wrong
<motion.div className="transition-all" animate={{ x: 100 }} />
// ✅ Correct
<motion.div animate={{ x: 100 }} />
Symptom : Build fails with "motion is not defined" or SSR errors.
Solution : Add "use client" directive:
"use client"
import { motion } from "motion/react"
See references/nextjs-integration.md for App Router patterns.
Symptom : Incomplete transitions when removing items from scrolled containers.
Solution : Add layoutScroll prop:
<motion.div layoutScroll className="overflow-auto">
{items.map(item => (
<motion.div key={item.id} layout>
{item.content}
</motion.div>
))}
</motion.div>
Status : ✅ Fixed in December 2024 (GitHub issue #2918 closed as completed)
Previous Symptom : Wrangler build failed with React import errors when using motion package.
Current State : Motion now works correctly with Cloudflare Workers. No workaround needed.
If you encounter build issues : Ensure you're using Motion v12.23.24 or later and Wrangler v3+.
GitHub issue: #2918 (closed as completed Dec 13, 2024)
Symptom : Layout animations in fixed elements have incorrect positioning.
Solution : Add layoutRoot prop:
<motion.div layoutRoot className="fixed top-0 left-0">
<motion.div layout>Content</motion.div>
</motion.div>
Symptom : Elements with layoutId inside AnimatePresence fail to unmount.
Solution : Wrap in LayoutGroup or avoid mixing exit + layout animations:
import { LayoutGroup } from "motion/react"
<LayoutGroup>
<AnimatePresence>
{items.map(item => (
<motion.div key={item.id} layoutId={item.id}>
{item.content}
</motion.div>
))}
</AnimatePresence>
</LayoutGroup>
Status : ✅ Fixed in January 2023 (GitHub issue #1567 closed via PR #1891)
Previous Symptom : MotionConfig reducedMotion setting didn't affect AnimatePresence animations.
Current State : MotionConfig now correctly applies reducedMotion to AnimatePresence components. The setting works as documented.
Optional Manual Control : If you need custom behavior beyond the built-in support:
const prefersReducedMotion = window.matchMedia("(prefers-reduced-motion: reduce)").matches
<motion.div
initial={{ opacity: prefersReducedMotion ? 1 : 0 }}
animate={{ opacity: 1 }}
transition={{ duration: prefersReducedMotion ? 0 : 0.3 }}
/>

Error : Reorder auto-scroll fails, doesn't work with Next.js routing Source : GitHub Issue #3469, #2183, #2101
Why It Happens :
Reorder.Group is inside element with overflow: auto/scroll, NOT when document itself is scrollablePrevention :
// ❌ Wrong - Page-level scrolling (auto-scroll fails)
<body style={{ height: "200vh" }}>
<Reorder.Group values={items} onReorder={setItems}>
{/* Auto-scroll doesn't trigger at viewport edges */}
</Reorder.Group>
</body>
// ✅ Correct - Container with overflow
<div style={{ height: "300px", overflow: "auto" }}>
<Reorder.Group values={items} onReorder={setItems}>
{items.map(item => (
<Reorder.Item key={item.id} value={item}>
{item.content}
</Reorder.Item>
))}
</Reorder.Group>
</div>
// ✅ Alternative - Use DnD Kit for complex cases
// Motion docs officially recommend DnD Kit for:
// - Multi-row reordering
// - Dragging between columns
// - Page-level scrollable containers
// - Complex drag-and-drop interactions
// Install: pnpm add @dnd-kit/core @dnd-kit/sortable @dnd-kit/utilities

Error : Drag gestures break when dragging from top to bottom in file trees Source : GitHub Issue #3169
Why It Happens : Only occurs with React 19 + StrictMode enabled + Ant Design components. Dragged element position breaks and appears offset. Does NOT occur in React 18 or React 19 without StrictMode. Only affects top-to-bottom drag (bottom-to-top works fine).
Prevention : Temporarily disable StrictMode for React 19 projects using drag gestures, or use React 18 if StrictMode is critical. Awaiting official fix from Motion team.
Error : Layout animations start from incorrect positions in scaled parent containers Source : GitHub Issue #3356
Why It Happens : Layout animation system uses scaled coordinates as if they were unscaled. Motion's layout animations work in pixels, while parent scale affects visual coordinates. The mismatch causes position calculation errors.
Prevention (Community Workaround) :
// Use transformTemplate to correct for parent scale
const scale = 2; // Parent's transform scale value
<div style={{ transform: `scale(${scale})` }}>
<motion.div
layout
transformTemplate={(latest, generated) => {
const match = /translate3d\((.+)px,\s?(.+)px,\s?(.+)px\)/.exec(generated);
if (match) {
const [, x, y, z] = match;
return `translate3d(${Number(x) / scale}px, ${Number(y) / scale}px, ${Number(z) / scale}px)`;
}
return generated;
}}
>
Content
</motion.div>
</div>
Limitations : Only works for layout animations only, doesn't fix other transforms, requires knowing parent scale value.
Error : Exit state stuck when child unmounts during exit animation Source : GitHub Issue #3243
Why It Happens : When child component inside AnimatePresence unmounts immediately after exit animation triggers, exit state gets stuck. Component incorrectly remains in "exit" state.
Prevention : Don't unmount motion components while AnimatePresence is handling their exit. Ensure motion.div stays mounted until exit completes. Use conditional rendering only on parent AnimatePresence children.
Error : Layout animations teleport instantly instead of animating smoothly Source : GitHub Issue #3401
Why It Happens : Using percentage-based x values in initial prop breaks layout animations when container uses display flex with justify-content center. Motion's layout animations work in pixels, while CSS percentage transforms are resolved relative to element/parent. The coordinate system mismatch causes position recalculation mid-frame.
Prevention : Convert percentage to pixels before animation. Calculate container width and use pixel values instead of percentage strings.
Error : 1px layout shift just before exit transition starts Source : GitHub Issue #3260
Why It Happens : When using AnimatePresence with mode popLayout, exiting element dimensions are captured and reapplied as inline styles. Sub-pixel values from getBoundingClientRect are rounded to nearest integer, causing visible layout shift. Can cause text wrapping changes.
Prevention : Use whole pixel values only for dimensions, or avoid popLayout for sub-pixel-sensitive layouts. No perfect workaround exists.
