Mastering Animations in React with Framer Motion

Animations breathe life into web applications, transforming static interfaces into engaging experiences. Framer Motion has emerged as the go-to animation library for React, offering powerful features with an intuitive API.

Why Framer Motion?

Traditional CSS animations and JavaScript-based libraries often require complex code for simple effects. Framer Motion simplifies this:

• Declarative syntax: Animations as props
• Performance: Hardware-accelerated by default
• Gestures: Built-in drag, tap, and hover support
• Spring physics: Natural, fluid motion
• Layout animations: Automatic smooth transitions

Getting Started

Installation

npm install framer-motion

Basic Animation

import { motion } from "framer-motion";

export default function FadeIn() {
  return (
    <motion.div
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
      transition={{ duration: 0.6 }}
    >
      Content fades in
    </motion.div>
  );
}

Essential Animation Patterns

1. Entrance Animations

Create engaging page load experiences:

export default function Hero() {
  return (
    <div>
      <motion.h1
        initial={{ opacity: 0, y: 20 }}
        animate={{ opacity: 1, y: 0 }}
        transition={{ duration: 0.6, delay: 0.2 }}
      >
        Welcome to Star Works
      </motion.h1>

      <motion.p
        initial={{ opacity: 0, y: 20 }}
        animate={{ opacity: 1, y: 0 }}
        transition={{ duration: 0.6, delay: 0.4 }}
      >
        Transform your digital presence
      </motion.p>

      <motion.button
        initial={{ opacity: 0, scale: 0.8 }}
        animate={{ opacity: 1, scale: 1 }}
        transition={{ duration: 0.4, delay: 0.6 }}
        whileHover={{ scale: 1.05 }}
        whileTap={{ scale: 0.95 }}
      >
        Get Started
      </motion.button>
    </div>
  );
}

2. Scroll-Triggered Animations

Animate elements as they enter the viewport:

export default function ScrollReveal() {
  return (
    <motion.div
      initial={{ opacity: 0, y: 50 }}
      whileInView={{ opacity: 1, y: 0 }}
      viewport={{ once: true, amount: 0.3 }}
      transition={{ duration: 0.6 }}
    >
      This appears when scrolled into view
    </motion.div>
  );
}

3. Staggered Animations

Create cascading effects for lists:

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 default function StaggeredList() {
  return (
    <motion.ul variants={container} initial="hidden" animate="show">
      {items.map((item, i) => (
        <motion.li key={i} variants={item}>
          {item}
        </motion.li>
      ))}
    </motion.ul>
  );
}

4. Interactive Hover Effects

export default function InteractiveCard() {
  return (
    <motion.div
      className="card"
      whileHover={{
        scale: 1.05,
        boxShadow: "0 10px 40px rgba(195, 240, 15, 0.3)",
      }}
      whileTap={{ scale: 0.98 }}
      transition={{ type: "spring", stiffness: 300 }}
    >
      Hover over me
    </motion.div>
  );
}

5. Drag Interactions

export default function DraggableElement() {
  return (
    <motion.div
      drag
      dragConstraints={{ left: -100, right: 100, top: -100, bottom: 100 }}
      dragElastic={0.2}
      whileDrag={{ scale: 1.1, cursor: "grabbing" }}
    >
      Drag me around
    </motion.div>
  );
}

Advanced Techniques

Layout Animations

Automatically animate layout changes:

import { AnimatePresence, motion } from "framer-motion";

export default function ExpandableCard() {
  const [isExpanded, setIsExpanded] = useState(false);

  return (
    <motion.div
      layout
      onClick={() => setIsExpanded(!isExpanded)}
      className="card"
    >
      <motion.h2 layout>Title</motion.h2>

      <AnimatePresence>
        {isExpanded && (
          <motion.div
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          >
            Additional content
          </motion.div>
        )}
      </AnimatePresence>
    </motion.div>
  );
}

Path Animations (SVG)

Animate SVG paths for dynamic graphics:

export default function AnimatedLogo() {
  return (
    <svg width="200" height="200">
      <motion.path
        d="M10 10 L190 190"
        stroke="#C3F00F"
        strokeWidth="4"
        fill="transparent"
        initial={{ pathLength: 0 }}
        animate={{ pathLength: 1 }}
        transition={{ duration: 2, ease: "easeInOut" }}
      />
    </svg>
  );
}

Custom Spring Animations

export default function BouncyButton() {
  return (
    <motion.button
      whileHover={{ scale: 1.1 }}
      transition={{
        type: "spring",
        stiffness: 400,
        damping: 10,
      }}
    >
      Bouncy!
    </motion.button>
  );
}

Performance Best Practices

1. Use Transform Properties

Animate transform and opacity for best performance:

// Good - GPU accelerated
<motion.div animate={{ x: 100, scale: 1.2, opacity: 0.5 }} />

// Avoid - triggers layout recalculation
<motion.div animate={{ width: 200, marginLeft: 50 }} />

2. Optimize with layoutId

For smooth shared element transitions:

<motion.div layoutId="unique-id">Shared element</motion.div>

3. Reduce Motion for Accessibility

Respect user preferences:

import { useReducedMotion } from "framer-motion";

export default function AccessibleAnimation() {
  const shouldReduceMotion = useReducedMotion();

  return (
    <motion.div
      initial={{ opacity: 0, y: shouldReduceMotion ? 0 : 20 }}
      animate={{ opacity: 1, y: 0 }}
    >
      Content
    </motion.div>
  );
}

Real-World Example: Animated Navigation

export default function AnimatedNav() {
  const [isOpen, setIsOpen] = useState(false);

  return (
    <>
      <motion.button
        onClick={() => setIsOpen(!isOpen)}
        animate={{ rotate: isOpen ? 90 : 0 }}
      >
        Menu
      </motion.button>

      <AnimatePresence>
        {isOpen && (
          <motion.nav
            initial={{ x: "100%" }}
            animate={{ x: 0 }}
            exit={{ x: "100%" }}
            transition={{ type: "spring", damping: 20 }}
          >
            <motion.ul
              variants={{
                open: {
                  transition: { staggerChildren: 0.07, delayChildren: 0.2 },
                },
                closed: {
                  transition: { staggerChildren: 0.05, staggerDirection: -1 },
                },
              }}
              initial="closed"
              animate="open"
              exit="closed"
            >
              {menuItems.map((item, i) => (
                <motion.li
                  key={i}
                  variants={{
                    open: { y: 0, opacity: 1 },
                    closed: { y: 50, opacity: 0 },
                  }}
                >
                  {item}
                </motion.li>
              ))}
            </motion.ul>
          </motion.nav>
        )}
      </AnimatePresence>
    </>
  );
}

Common Pitfalls

1. Over-Animation

Don't animate everything. Be selective:

• ✅ Important state changes
• ✅ User interactions
• ✅ Page transitions
• ❌ Every hover effect
• ❌ Continuous background animations

2. Ignoring Performance

Monitor frame rates:

import { useAnimationFrame } from "framer-motion";

useAnimationFrame((time, delta) => {
  if (delta > 16.67) {
    console.warn("Frame drop detected");
  }
});

3. Forgetting Exit Animations

Always wrap with AnimatePresence for exit animations:

<AnimatePresence>
  {isVisible && (
    <motion.div
      initial={{ opacity: 0 }}
      animate={{ opacity: 1 }}
      exit={{ opacity: 0 }}
    >
      Content
    </motion.div>
  )}
</AnimatePresence>
