Framer Motion Basics

Installation

npm install framer-motion

Basic Animation

import { motion } from 'framer-motion'

export function FadeIn({ children }: { children: React.ReactNode }) {
  return (
    <motion.div
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
      transition={{ duration: 0.5 }}
    >
      {children}
    </motion.div>
  )
}

Common Animation Patterns

Pattern 1: Fade In on Mount

import { motion } from 'framer-motion'

export function Card({ children }: { children: React.ReactNode }) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 20 }}
      animate={{ opacity: 1, y: 0 }}
      transition={{ duration: 0.4, ease: 'easeOut' }}
      className="p-6 bg-white rounded-lg shadow"
    >
      {children}
    </motion.div>
  )
}

Pattern 2: Staggered List Animation

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 }
}

export function List({ items }: { items: string[] }) {
  return (
    <motion.ul
      variants={container}
      initial="hidden"
      animate="show"
    >
      {items.map((text, i) => (
        <motion.li key={i} variants={item}>
          {text}
        </motion.li>
      ))}
    </motion.ul>
  )
}

Pattern 3: Button Hover Animation

import { motion } from 'framer-motion'

export function AnimatedButton({ children, onClick }: {
  children: React.ReactNode
  onClick: () => void
}) {
  return (
    <motion.button
      onClick={onClick}
      whileHover={{ scale: 1.05 }}
      whileTap={{ scale: 0.95 }}
      transition={{ type: 'spring', stiffness: 400, damping: 17 }}
      className="px-6 py-3 bg-blue-600 text-white rounded-lg"
    >
      {children}
    </motion.button>
  )
}

Pattern 4: Modal / Dialog Animation

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

export function Modal({ isOpen, onClose, children }: {
  isOpen: boolean
  onClose: () => void
  children: React.ReactNode
}) {
  return (
    <AnimatePresence>
      {isOpen && (
        <>
          {/* Backdrop */}
          <motion.div
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
            onClick={onClose}
            className="fixed inset-0 bg-black/50 z-40"
          />

          {/* Modal */}
          <motion.div
            initial={{ opacity: 0, scale: 0.9, y: 20 }}
            animate={{ opacity: 1, scale: 1, y: 0 }}
            exit={{ opacity: 0, scale: 0.9, y: 20 }}
            transition={{ type: 'spring', damping: 25, stiffness: 300 }}
            className="fixed inset-0 flex items-center justify-center z-50 p-4"
          >
            <div className="bg-white rounded-lg p-6 max-w-md w-full">
              {children}
            </div>
          </motion.div>
        </>
      )}
    </AnimatePresence>
  )
}

Pattern 5: Page Transition

'use client'
import { motion } from 'framer-motion'
import { usePathname } from 'next/navigation'

export function PageTransition({ children }: { children: React.ReactNode }) {
  const pathname = usePathname()

  return (
    <motion.div
      key={pathname}
      initial={{ opacity: 0, x: 20 }}
      animate={{ opacity: 1, x: 0 }}
      exit={{ opacity: 0, x: -20 }}
      transition={{ duration: 0.3 }}
    >
      {children}
    </motion.div>
  )
}

// Usage in layout
export default function Layout({ children }) {
  return (
    <PageTransition>
      {children}
    </PageTransition>
  )
}

Scroll Animations

Scroll-Triggered Animation

import { motion, useScroll, useTransform } from 'framer-motion'
import { useRef } from 'react'

export function ScrollReveal({ children }: { children: React.ReactNode }) {
  const ref = useRef(null)
  const { scrollYProgress } = useScroll({
    target: ref,
    offset: ['start end', 'end start']
  })

  const opacity = useTransform(scrollYProgress, [0, 0.3, 0.7, 1], [0, 1, 1, 0])
  const y = useTransform(scrollYProgress, [0, 0.3, 0.7, 1], [100, 0, 0, -100])

  return (
    <motion.div
      ref={ref}
      style={{ opacity, y }}
    >
      {children}
    </motion.div>
  )
}

Parallax Effect

import { motion, useScroll, useTransform } from 'framer-motion'

export function ParallaxSection() {
  const { scrollY } = useScroll()
  const y = useTransform(scrollY, [0, 500], [0, 150])

  return (
    <div className="relative h-screen overflow-hidden">
      <motion.div
        style={{ y }}
        className="absolute inset-0"
      >
        <img src="/background.jpg" alt="" className="w-full h-full object-cover" />
      </motion.div>

      <div className="relative z-10 flex items-center justify-center h-full">
        <h1 className="text-6xl font-bold text-white">
          Parallax Effect
        </h1>
      </div>
    </div>
  )
}

Scroll Progress Indicator

import { motion, useScroll } from 'framer-motion'

export function ScrollProgress() {
  const { scrollYProgress } = useScroll()

  return (
    <motion.div
      style={{ scaleX: scrollYProgress }}
      className="fixed top-0 left-0 right-0 h-1 bg-blue-600 origin-left z-50"
    />
  )
}

  return (
    <motion.div
      animate={{ rotate: 360 }}
      transition={{

        repeat: Infinity,
        ease: 'linear'

        duration: 1.5,
        repeat: Infinity,
        ease: 'easeInOut'
      }}
      className="bg-gray-200 rounded h-4 w-full"
    />
  )
}

Pulsing Dots

import { motion } from 'framer-motion'

const dotVariants = {
  start: { scale: 0.8, opacity: 0.5 },
  end: { scale: 1.2, opacity: 1 }
}

export function PulsingDots() {
  return (
    <div className="flex gap-2">
      {[0, 1, 2].map((i) => (
        <motion.div
          key={i}
          variants={dotVariants}
          animate="end"
          initial="start"
          transition={{
            duration: 0.6,
            repeat: Infinity,
            repeatType: 'reverse',
            delay: i * 0.2
          }}
          className="w-3 h-3 bg-blue-600 rounded-full"
        />
      ))}
    </div>
  )
}

CSS Animations
