Framer Motion for Next.js: Scroll Animations, Page Transitions, and Micro-Interactions

#nextjs #react #webdev #typescript

Animations make apps feel polished. Done wrong, they tank performance and annoy users. Framer Motion makes it easy to do them right in Next.js.

Setup 

npm install framer-motion
Enter fullscreen mode Exit fullscreen mode

Framer Motion requires Client Components:

'use client'
import { motion } from 'framer-motion'
Enter fullscreen mode Exit fullscreen mode

Fade In on Mount

The most common animation -- elements appearing smoothly:

'use client'
import { motion } from 'framer-motion'

export function FadeIn({ children, delay = 0 }: { children: React.ReactNode; delay?: number }) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 16 }}
      animate={{ opacity: 1, y: 0 }}
      transition={{ duration: 0.4, delay, ease: 'easeOut' }}
    >
      {children}
    </motion.div>
  )
}

// Usage
<FadeIn><h1>Welcome</h1></FadeIn>
<FadeIn delay={0.1}><p>Subtitle appears after heading</p></FadeIn>
<FadeIn delay={0.2}><Button>CTA</Button></FadeIn>
Enter fullscreen mode Exit fullscreen mode

Stagger Children

Animate list items one after another:

'use client'
import { motion } from 'framer-motion'

const container = {
  hidden: { opacity: 0 },
  show: {
    opacity: 1,
    transition: { staggerChildren: 0.1 }
  }
}

const item = {
  hidden: { opacity: 0, y: 20 },
  show: { opacity: 1, y: 0, transition: { duration: 0.4 } }
}

export function StaggerList({ items }: { items: string[] }) {
  return (
    <motion.ul variants={container} initial='hidden' animate='show'>
      {items.map((item, i) => (
        <motion.li key={i} variants={item}>{item}</motion.li>
      ))}
    </motion.ul>
  )
}
Enter fullscreen mode Exit fullscreen mode

Scroll-Triggered Animations

Animate when elements enter the viewport:

'use client'
import { motion } from 'framer-motion'

export function ScrollReveal({ children }: { children: React.ReactNode }) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 32 }}
      whileInView={{ opacity: 1, y: 0 }}
      viewport={{ once: true, margin: '-50px' }}
      transition={{ duration: 0.5, ease: 'easeOut' }}
    >
      {children}
    </motion.div>
  )
}
Enter fullscreen mode Exit fullscreen mode

viewport={{ once: true }} means it only animates once -- not every time it enters/leaves the viewport.

Hover and Tap Micro-Interactions 

// Card lift on hover
<motion.div
  whileHover={{ y: -4, boxShadow: '0 20px 40px rgba(0,0,0,0.1)' }}
  transition={{ duration: 0.2 }}
>
  <ProductCard />
</motion.div>

// Button press effect
<motion.button
  whileHover={{ scale: 1.02 }}
  whileTap={{ scale: 0.98 }}
  transition={{ duration: 0.1 }}
>
  Buy Now
</motion.button>
Enter fullscreen mode Exit fullscreen mode

AnimatePresence for Exit Animations

Elements leaving the DOM can be animated:

'use client'
import { AnimatePresence, motion } from 'framer-motion'

export function Toast({ message, visible }: { message: string; visible: boolean }) {
  return (
    <AnimatePresence>
      {visible && (
        <motion.div
          initial={{ opacity: 0, y: -16, scale: 0.9 }}
          animate={{ opacity: 1, y: 0, scale: 1 }}
          exit={{ opacity: 0, y: -8, scale: 0.95 }}
          transition={{ duration: 0.2 }}
          className='fixed top-4 right-4 bg-green-600 text-white px-4 py-2 rounded-lg'
        >
          {message}
        </motion.div>
      )}
    </AnimatePresence>
  )
}
Enter fullscreen mode Exit fullscreen mode

Without AnimatePresence, removing an element from the DOM is instant. With it, the exit animation plays first.

Page Transitions 

// app/template.tsx (different from layout.tsx -- remounts on navigation)
'use client'
import { motion } from 'framer-motion'

export default function Template({ children }: { children: React.ReactNode }) {
  return (
    <motion.div
      initial={{ opacity: 0, x: -8 }}
      animate={{ opacity: 1, x: 0 }}
      transition={{ duration: 0.3, ease: 'easeOut' }}
    >
      {children}
    </motion.div>
  )
}
Enter fullscreen mode Exit fullscreen mode

template.tsx (not layout.tsx) remounts on every navigation, triggering the animation.

Performance Rules

Animate only transform and opacity -- these use GPU compositing:

// Fast -- GPU composited
initial={{ opacity: 0, y: 20, scale: 0.95 }}

// Slow -- triggers layout/paint
initial={{ height: 0, padding: 0 }}
Enter fullscreen mode Exit fullscreen mode

Reduce motion for accessibility:

import { useReducedMotion } from 'framer-motion'

function AnimatedCard({ children }) {
  const shouldReduceMotion = useReducedMotion()
  return (
    <motion.div
      initial={shouldReduceMotion ? false : { opacity: 0, y: 20 }}
      animate={{ opacity: 1, y: 0 }}
    >
      {children}
    </motion.div>
  )
}
Enter fullscreen mode Exit fullscreen mode

Keep durations short: 150-400ms feels responsive. Anything over 600ms feels slow.
