Micro Lottie React

The smallest React Lottie player. 15KB. Zero deps. Supports .lottie files.

🚀 Why Micro Lottie React?

Current Lottie players are bloated (50-200KB+), have heavy dependencies, and poor mobile performance. Micro Lottie React is 10x smaller and lightning fast.

🚀 Quick Start

npm install micro-lottie-react

Basic Usage

import { LottiePlayer } from "micro-lottie-react";

function App() {
  return (
    <LottiePlayer
      src="/animation.lottie"
      autoplay
      loop
      style={{ width: 300, height: 300 }}
    />
  );
}

Advanced Usage with Hooks

import { useLottie } from "micro-lottie-react";
import { useRef } from "react";

function AdvancedPlayer() {
  const containerRef = useRef(null);

  const { play, pause, seek, progress, isPlaying } = useLottie({
    container: containerRef,
    src: "/complex-animation.json",
    renderer: "canvas", // or 'svg'
    autoplay: false,
    loop: true,
    onComplete: () => console.log("Animation completed!"),
    onProgress: (progress) => console.log(`Progress: ${progress * 100}%`),
    segments: [0, 120], // Play frames 0-120 only
  });

  return (
    <div>
      <div ref={containerRef} style={{ width: 400, height: 400 }} />

      <div>
        <button onClick={isPlaying ? pause : play}>
          {isPlaying ? "⏸️ Pause" : "▶️ Play"}
        </button>
        <button onClick={() => seek(0)}>⏮️ Reset</button>
        <button onClick={() => seek(0.5)}>⏯️ Seek 50%</button>
      </div>

      <div>Progress: {Math.round(progress * 100)}%</div>
    </div>
  );
}

🎨 Examples

React with Vite

// Perfect for modern React applications
import { LottiePlayer } from "micro-lottie-react";

export default function Hero() {
  return (
    <section className="hero">
      <LottiePlayer
        src="/hero-animation.lottie"
        style={{ width: "100%", maxWidth: 600 }}
      />
    </section>
  );
}

Next.js Integration

// Works seamlessly with SSR
import dynamic from "next/dynamic";

const LottiePlayer = dynamic(
  () => import("micro-lottie-react").then((mod) => mod.LottiePlayer),
  { ssr: false }
);

export default function HomePage() {
  return (
    <LottiePlayer
      src="/animations/loading.lottie"
      style={{ width: 200, height: 200 }}
    />
  );
}

Interactive Controls

import { useLottie } from "micro-lottie-react";

function InteractiveDemo() {
  const containerRef = useRef(null);
  const [speed, setSpeed] = useState(1);

  const {
    play,
    pause,
    seek,
    setSpeed: setAnimationSpeed,
    progress,
  } = useLottie({
    container: containerRef,
    src: "/interactive-animation.json",
    speed,
    onProgress: (p) => console.log(`Frame: ${Math.round(p * 100)}`),
  });

  useEffect(() => {
    setAnimationSpeed(speed);
  }, [speed, setAnimationSpeed]);

  return (
    <div>
      <div ref={containerRef} style={{ width: 400, height: 400 }} />

      <div className="controls">
        <button onClick={play}>Play</button>
        <button onClick={pause}>Pause</button>
        <input
          type="range"
          min="0"
          max="1"
          step="0.01"
          value={progress}
          onChange={(e) => seek(parseFloat(e.target.value))}
        />
        <input
          type="range"
          min="0.1"
          max="3"
          step="0.1"
          value={speed}
          onChange={(e) => setSpeed(parseFloat(e.target.value))}
        />
        <span>Speed: {speed}x</span>
      </div>
    </div>
  );
}

⚡ Performance Tips

1. Use Canvas Rendering for Complex Animations

<LottiePlayer src="/complex-animation.lottie" renderer="canvas" />

2. Implement Lazy Loading

function LazyLottie({ src }) {
  const [isVisible, setIsVisible] = useState(false);
  const ref = useRef();

  useEffect(() => {
    const observer = new IntersectionObserver(([entry]) => {
      if (entry.isIntersecting) {
        setIsVisible(true);
        observer.disconnect();
      }
    });

    if (ref.current) observer.observe(ref.current);
    return () => observer.disconnect();
  }, []);

  return <div ref={ref}>{isVisible && <LottiePlayer src={src} />}</div>;
}

3. Optimize File Sizes

# Convert JSON to smaller .lottie format
npx @lottiefiles/lottie-cli export input.json output.lottie

# Results in ~50% smaller files

🔄 Migration Guide

From lottie-react

// Before (lottie-react)
import Lottie from "lottie-react";
import animationData from "./animation.json";

<Lottie animationData={animationData} loop autoplay />;

// After (micro-lottie-react)
import { LottiePlayer } from "micro-lottie-react";

<LottiePlayer src="/animation.lottie" loop autoplay />;

From react-lottie

// Before (react-lottie)
import Lottie from "react-lottie";

const options = {
  loop: true,
  autoplay: true,
  animationData: animationData,
};

<Lottie options={options} height={400} width={400} />;

// After (micro-lottie-react)
import { LottiePlayer } from "micro-lottie-react";

<LottiePlayer
  src="/animation.lottie"
  loop
  autoplay
  style={{ width: 400, height: 400 }}
/>;
