Core Techniques

Path Drawing Animation (Framer Motion)

import { motion } from 'framer-motion';

function DrawPath() {
  return (
    <svg viewBox="0 0 100 100" className="w-24 h-24">
      <motion.path
        d="M10 50 Q 50 10, 90 50 T 90 90"
        fill="transparent"
        stroke="#3B82F6"
        strokeWidth="4"
        initial={{ pathLength: 0 }}
        animate={{ pathLength: 1 }}
        transition={{ duration: 2, ease: 'easeInOut' }}
      />
    </svg>
  );
}

Path Drawing with CSS

.svg-path {
  stroke-dasharray: 1000; /* Total path length */
  stroke-dashoffset: 1000; /* Start hidden */
  animation: draw 2s ease-in-out forwards;
}

@keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}

Calculate Path Length

// Get actual path length for accurate animation
useEffect(() => {
  const path = document.querySelector('.animated-path') as SVGPathElement;
  if (path) {
    const length = path.getTotalLength();
    console.log('Path length:', length);
  }
}, []);

Animated Icon Components

Checkmark Animation

import { motion } from 'framer-motion';

function AnimatedCheck({ isVisible }: { isVisible: boolean }) {
  return (
    <svg viewBox="0 0 24 24" className="w-6 h-6">
      {/* Circle background */}
      <motion.circle
        cx="12"
        cy="12"
        r="10"
        fill="#22C55E"
        initial={{ scale: 0 }}
        animate={{ scale: isVisible ? 1 : 0 }}
        transition={{ type: 'spring', stiffness: 300, damping: 20 }}
      />

      {/* Checkmark path */}
      <motion.path
        d="M6 12l4 4 8-8"
        fill="transparent"
        stroke="white"
        strokeWidth="2"
        strokeLinecap="round"
        strokeLinejoin="round"
        initial={{ pathLength: 0 }}
        animate={{ pathLength: isVisible ? 1 : 0 }}
        transition={{ delay: 0.2, duration: 0.3, ease: 'easeOut' }}
      />
    </svg>
  );
}

Hamburger to X Animation

import { motion } from 'framer-motion';

function MenuIcon({ isOpen }: { isOpen: boolean }) {
  const variant = isOpen ? 'open' : 'closed';

  const topLineVariants = {
    closed: { rotate: 0, y: 0 },
    open: { rotate: 45, y: 8 },
  };

  const middleLineVariants = {
    closed: { opacity: 1 },
    open: { opacity: 0 },
  };

  const bottomLineVariants = {
    closed: { rotate: 0, y: 0 },
    open: { rotate: -45, y: -8 },
  };

  return (
    <svg viewBox="0 0 24 24" className="w-6 h-6">
      <motion.line
        x1="4" y1="6" x2="20" y2="6"
        stroke="currentColor"
        strokeWidth="2"
        strokeLinecap="round"
        variants={topLineVariants}
        animate={variant}
        transition={{ duration: 0.3 }}
        style={{ transformOrigin: 'center' }}
      />
      <motion.line
        x1="4" y1="12" x2="20" y2="12"
        stroke="currentColor"
        strokeWidth="2"
        strokeLinecap="round"
        variants={middleLineVariants}
        animate={variant}
        transition={{ duration: 0.2 }}
      />
      <motion.line
        x1="4" y1="18" x2="20" y2="18"
        stroke="currentColor"
        strokeWidth="2"
        strokeLinecap="round"
        variants={bottomLineVariants}
        animate={variant}
        transition={{ duration: 0.3 }}
        style={{ transformOrigin: 'center' }}
      />
    </svg>
  );
}

Loading Spinner

import { motion } from 'framer-motion';

function Spinner() {
  return (
    <svg viewBox="0 0 50 50" className="w-12 h-12">
      {/* Background circle */}
      <circle
        cx="25"

          },
        }}
        style={{ transformOrigin: 'center' }}
      />
    </svg>
  );
}

Shape Morphing

Framer Motion Morphing

import { motion, useAnimation } from 'framer-motion';

const shapes = {
  circle: 'M50,10 A40,40 0 1,1 50,90 A40,40 0 1,1 50,10',
  square: 'M10,10 L90,10 L90,90 L10,90 Z',
  triangle: 'M50,10 L90,90 L10,90 Z',
};

function MorphingShape() {
  const [currentShape, setCurrentShape] = useState<keyof typeof shapes>('circle');

  return (
    <svg viewBox="0 0 100 100" className="w-32 h-32">
      <motion.path
        fill="#3B82F6"
        animate={{ d: shapes[currentShape] }}
        transition={{ duration: 0.5, ease: 'easeInOut' }}
      />
    </svg>
  );
}

GSAP MorphSVG

import gsap from 'gsap';
import { MorphSVGPlugin } from 'gsap/MorphSVGPlugin';

gsap.registerPlugin(MorphSVGPlugin);

function GSAPMorph() {
  useEffect(() => {
    gsap.to('#shape', {
      duration: 1,
      morphSVG: '#targetShape',
      ease: 'power2.inOut',
    });
  }, []);

  return (
    <svg>
      <path id="shape" d="M10,10 L90,10 L90,90 L10,90 Z" />
      <path id="targetShape" d="M50,10 A40,40 0 1,1 50,90 A40,40 0 1,1 50,10" style={{ visibility: 'hidden' }} />
    </svg>
  );
}

Complex SVG Animations

Animated Logo

function AnimatedLogo() {
  const controls = useAnimation();

  const logoVariants = {
    hidden: { opacity: 0 },
    visible: {
      opacity: 1,
      transition: {
        staggerChildren: 0.1,
        delayChildren: 0.2,
      },
    },
  };

  const pathVariants = {
    hidden: { pathLength: 0, opacity: 0 },
    visible: {
      pathLength: 1,
      opacity: 1,
      transition: { duration: 1, ease: 'easeInOut' },
    },
  };

  const fillVariants = {
    hidden: { fillOpacity: 0 },
    visible: {
      fillOpacity: 1,
      transition: { delay: 0.5, duration: 0.5 },
    },
  };

  return (
    <motion.svg
      viewBox="0 0 200 60"
      className="w-48"
      variants={logoVariants}
      initial="hidden"
      animate="visible"
    >
      {/* Letter outlines */}
      <motion.path
        d="M10,50 L10,10 L40,10 L40,30 L20,30 L20,50"
        fill="none"
        stroke="#3B82F6"
        strokeWidth="2"
        variants={pathVariants}
      />
      {/* Fill after stroke */}
      <motion.path
        d="M10,50 L10,10 L40,10 L40,30 L20,30 L20,50"
        fill="#3B82F6"
        variants={fillVariants}
      />
    </motion.svg>
  );
}

Data Visualization Animation

function AnimatedBarChart({ data }: { data: number[] }) {
  const maxValue = Math.max(...data);

  return (
    <svg viewBox="0 0 300 200" className="w-full h-48">
      {data.map((value, index) => {
        const barHeight = (value / maxValue) * 160;
        const barWidth = 40;
        const gap = 20;
        const x = index * (barWidth + gap) + 20;
        const y = 180 - barHeight;

        return (
          <motion.rect
            key={index}
            x={x}
            y={180}
            width={barWidth}
            height={0}
            fill="#3B82F6"
            rx="4"
            initial={{ height: 0, y: 180 }}
            animate={{ height: barHeight, y }}
            transition={{
              duration: 0.8,
              delay: index * 0.1,
              ease: [0.25, 0.1, 0.25, 1],
            }}
          />
        );
      })}
    </svg>
  );
}

Animated Circle Progress

function CircleProgress({ progress }: { progress: number }) {
  const radius = 40;
  const circumference = 2 * Math.PI * radius;

  return (
    <svg viewBox="0 0 100 100" className="w-24 h-24 -rotate-90">
      {/* Background circle */}
      <circle
        cx="50"
        cy="50"
        r={radius}
        fill="none"
        stroke="#E5E7EB"
        strokeWidth="8"
      />

      {/* Progress circle */}
      <motion.circle
        cx="50"
        cy="50"
        r={radius}
        fill="none"
        stroke="#3B82F6"
        strokeWidth="8"
        strokeLinecap="round"
        initial={{ strokeDasharray: circumference, strokeDashoffset: circumference }}
        animate={{ strokeDashoffset: circumference * (1 - progress) }}
        transition={{ duration: 1, ease: 'easeOut' }}
      />

      {/* Percentage text */}
      <motion.text
        x="50"
        y="50"
        textAnchor="middle"
        dominantBaseline="middle"
        className="text-2xl font-bold fill-current rotate-90"
        initial={{ opacity: 0 }}
        animate={{ opacity: 1 }}
      >
        {Math.round(progress * 100)}%
      </motion.text>
    </svg>
  );
}

Performance Tips

1. Use will-change: transform for GPU acceleration
2. Optimize SVG paths - simplify complex paths
3. Use pathLength property for easy animations
4. Avoid animating fill/stroke on complex shapes - use opacity instead
5. Group related elements with <g> for batch transforms

Examples

<example> Context: User wants an animated checkmark icon user: "Create an animated checkmark that draws itself" assistant: Using path animation with Framer Motion: ```tsx function AnimatedCheckmark() { return ( <motion.svg viewBox="0 0 24 24" className="w-8 h-8"> <motion.path d="M5 13l4 4L19 7" fill="none" stroke="#22C55E" strokeWidth="2" strokeLinecap="round" strokeLinejoin="round" initial={{ pathLength: 0, opacity: 0 }} animate={{ pathLength: 1, opacity: 1 }} transition={{ duration: 0.5, ease: 'easeOut' }} /> </motion.svg> ); } ``` </example> <example> Context: User needs an animated loading indicator user: "Build a circular loading spinner with SVG" assistant: Using stroke animation for smooth loading: ```tsx function LoadingSpinner() { return ( <motion.svg viewBox="0 0 50 50" className="w-10 h-10 animate-spin"> <circle cx="25" cy="25" r="20" fill="none" stroke="#E5E7EB" strokeWidth="4" /> <motion.circle cx="25" cy="25" r="20" fill="none" stroke="#3B82F6" strokeWidth="4" strokeLinecap="round" strokeDasharray="125.6" // 2 * PI * 20 initial={{ strokeDashoffset: 125.6 }} animate={{ strokeDashoffset: 31.4 }} // 75% of circumference /> </motion.svg> ); } ``` </example>
