Import the file into Remotion
Copy the file into the Remotion project. The recommended way is to put the JSON inside the public/ folder of Remotion (create it if necessary) and then load it using staticFile():
Animation.tsxtsximport {Lottie ,LottieAnimationData } from "@remotion/lottie";import {useEffect ,useState } from "react";import {cancelRender ,continueRender ,delayRender ,staticFile ,} from "remotion";constBalloons = () => {const [handle ] =useState (() =>delayRender ("Loading Lottie animation"));const [animationData ,setAnimationData ] =useState <LottieAnimationData | null>(null);useEffect (() => {fetch (staticFile ("animation.json")).then ((data ) =>data .json ()).then ((json ) => {setAnimationData (json );continueRender (handle );}).catch ((err ) => {cancelRender (err );});}, [handle ]);if (!animationData ) {return null;}return <Lottie animationData ={animationData } />;};
