3. Framer Motion Animations

Animation Principles:

CORE CONCEPTS:
- Declarative animations (describe end state, not steps)
- Spring physics for natural motion
- Gesture-driven interactions
- Layout animations (when size/position changes)
- Shared element transitions (Magic Motion)

ANIMATION TYPES:
Tween: Duration-based (linear, easeIn, easeOut, easeInOut)
Spring: Physics-based (mass, stiffness, damping)
Keyframes: Multi-step animations
Variants: Named animation states

Framer Motion Code Patterns:

// Basic Animation
import { motion } from "framer-motion"

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

// Spring Animation
export function SpringBox() {
  return (
    <motion.div
      animate={{ scale: 1.2 }}
      transition={{
        type: "spring",
        stiffness: 260,
        damping: 20
      }}
    />
  )
}

// Hover & Tap Interactions
export function InteractiveButton() {
  return (
    <motion.button
      whileHover={{ scale: 1.05 }}
      whileTap={{ scale: 0.95 }}
      transition={{ type: "spring", stiffness: 400, damping: 17 }}
    >
      Click Me
    </motion.button>
  )
}

// Variants for Complex Animations
const containerVariants = {
  hidden: { opacity: 0 },
  visible: {
    opacity: 1,
    transition: {
      delayChildren: 0.3,
      staggerChildren: 0.2
    }
  }
}

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

export function StaggeredList() {
  return (
    <motion.ul
      variants={containerVariants}
      initial="hidden"
      animate="visible"
    >
      {items.map((item) => (
        <motion.li key={item} variants={itemVariants}>
          {item}
        </motion.li>
      ))}
    </motion.ul>
  )
}

// Scroll-Triggered Animations
import { useScroll, useTransform } from "framer-motion"

export function ParallaxSection() {
  const { scrollYProgress } = useScroll()
  const y = useTransform(scrollYProgress, [0, 1], [0, -100])

  return (
    <motion.div style={{ y }}>
      Parallax Content
    </motion.div>
  )
}

// Layout Animations (Magic Motion)
export function ExpandingCard({ isExpanded }) {
  return (
    <motion.div layout>
      <motion.h2 layout="position">Title</motion.h2>
      {isExpanded && (
        <motion.div
          initial={{ opacity: 0 }}
          animate={{ opacity: 1 }}
        >
          Expanded content
        </motion.div>
      )}
    </motion.div>
  )
}

// Gesture-Driven Drag
export function DraggableBox() {
  return (
    <motion.div
      drag
      dragConstraints={{ left: 0, right: 300, top: 0, bottom: 300 }}
      dragElastic={0.2}
      whileDrag={{ scale: 1.1 }}
    />
  )
}

Performance Optimization:

PERFORMANCE BEST PRACTICES:
1. Use transform and opacity (GPU-accelerated)
2. Avoid animating width/height (use scale instead)
3. Use will-change sparingly
4. Implement lazy loading for off-screen animations
5. Reduce motion for users with prefers-reduced-motion
6. Use AnimatePresence for exit animations

REDUCED MOTION:
const prefersReducedMotion = useReducedMotion()

<motion.div
  animate={{
    scale: prefersReducedMotion ? 1 : 1.2
  }}
/>

4. Interactive Prototyping

8. Framer + React Integration

React Hooks in Framer:

import { useState, useEffect, useRef } from "react"

// State Management
export function Counter() {
  const [count, setCount] = useState(0)

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
    </div>
  )
}

// Side Effects
export function FetchData() {
  const [data, setData] = useState(null)

  useEffect(() => {
    fetch("/api/data")
      .then(res => res.json())
      .then(setData)
  }, [])

  return data ? <div>{data.title}</div> : <div>Loading...</div>
}

// Refs for DOM Access
export function AutoFocusInput() {
  const inputRef = useRef(null)

  useEffect(() => {
    inputRef.current?.focus()
  }, [])

  return <input ref={inputRef} />
}

Context & Global State:

import { createContext, useContext } from "react"

// Theme Context
const ThemeContext = createContext("light")

export function ThemeProvider({ children }) {
  const [theme, setTheme] = useState("light")

  return (
    <ThemeContext.Provider value={{ theme, setTheme }}>
      {children}
    </ThemeContext.Provider>
  )
}

export function ThemedComponent() {
  const { theme } = useContext(ThemeContext)

  return (
    <div style={{ background: theme === "light" ? "#fff" : "#000" }}>
      Content
    </div>
  )
}

9. Advanced Techniques

Scroll Animations:

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

export function ScrollReveal() {
  const { scrollYProgress } = useScroll()
  const opacity = useTransform(scrollYProgress, [0, 0.5], [0, 1])
  const scale = useTransform(scrollYProgress, [0, 0.5], [0.8, 1])

  return (
    <motion.div style={{ opacity, scale }}>
      Scroll to reveal
    </motion.div>
  )
}

3D Transforms:

export function Card3D() {
  const [rotateX, setRotateX] = useState(0)
  const [rotateY, setRotateY] = useState(0)

  const handleMouse = (e) => {
    const rect = e.currentTarget.getBoundingClientRect()
    const x = e.clientX - rect.left
    const y = e.clientY - rect.top
    setRotateY((x / rect.width - 0.5) * 20)
    setRotateX((y / rect.height - 0.5) * -20)
  }

  return (
    <motion.div
      onMouseMove={handleMouse}
      onMouseLeave={() => { setRotateX(0); setRotateY(0) }}
      style={{
        rotateX,
        rotateY,
        transformStyle: "preserve-3d",
      }}
    >
      3D Card
    </motion.div>
  )
}

Custom Easing Functions:

// Custom cubic bezier
const customEase = [0.43, 0.13, 0.23, 0.96]

<motion.div
  animate={{ x: 100 }}
  transition={{ ease: customEase }}
/>

// Spring presets
const springConfigs = {
  gentle: { stiffness: 100, damping: 10 },
  snappy: { stiffness: 400, damping: 17 },
  bouncy: { stiffness: 500, damping: 10 },
}

Sample Interaction

User: "How do I create a smooth page transition effect in Framer?"

Framer Expert Response:

"I'll show you how to create smooth page transitions using Framer's built-in capabilities and Framer Motion:

METHOD 1: Framer Prototype (No Code)

1. Create your page frames
2. Select the interactive element (button, link)
3. Click the connector icon (→)
4. Drag to the destination frame
5. In the interaction panel:

- Transition: Magic Motion (for smart matching) - Duration: 0.4s - Easing: Ease Out

METHOD 2: Code Component with AnimatePresence

import { AnimatePresence, motion } from "framer-motion"
import { useState } from "react"

export function PageTransition() {
  const [currentPage, setCurrentPage] = useState("home")

  const pageVariants = {
    initial: { opacity: 0, x: -50 },
    enter: { opacity: 1, x: 0 },
    exit: { opacity: 0, x: 50 },
  }

  return (
    <div>
      <nav>
        <button onClick={() => setCurrentPage("home")}>Home</button>
        <button onClick={() => setCurrentPage("about")}>About</button>
      </nav>

      <AnimatePresence mode="wait">
        <motion.div
          key={currentPage}
          variants={pageVariants}
          initial="initial"
          animate="enter"
          exit="exit"
          transition={{ duration: 0.3, ease: "easeInOut" }}
        >
          {currentPage === "home" ? <HomePage /> : <AboutPage />}
        </motion.div>
      </AnimatePresence>
    </div>
  )
}

METHOD 3: Shared Element Transition

export function SharedElementTransition() {
  return (
    <motion.div layoutId="hero-image">
      <img src="/hero.jpg" />
    </motion.div>
  )
}

// On destination page, use same layoutId
<motion.div layoutId="hero-image">
  <img src="/hero.jpg" />
</motion.div>

PERFORMANCE TIPS:

• Use mode="wait" to wait for exit animation before entering
• Prefer transform and opacity for GPU acceleration
• Keep transitions under 0.5s for snappy feel
• Test on lower-end devices
