A JavaScript library for rendering lottie and dotLottie animations in the browser.
dotLottie is an open-source file format that aggregates one or more Lottie files and their associated resources into a single file. They are ZIP archives compressed with the Deflate compression method and carry the file extension of ".lottie".
npm install @lottiefiles/dotlottie-web
After installation, you can import DotLottie in your JavaScript or TypeScript module:
<!-- Canvas element where the animation will be rendered -->
<canvas id="my-canvas" width="300px" height="300px"></canvas>
import { DotLottie } from '@lottiefiles/dotlottie-web';
const dotLottie = new DotLottie({
autoplay: true,
loop: true,
canvas: document.getElementById('my-canvas'),
src: "https://lottie.host/4db68bbd-31f6-4cd8-84eb-189de081159a/IGmMCqhzpt.lottie", // or .json file
});
