Loading Lottie animations from staticFile()

In order to load a Lottie animation from a file that has been put into the public/ folder, use staticFile() in combination with fetch and Remotion's delayRender() function.

Use the LottieAnimationData type to keep a state using React's useState() and only render the <Lottie> component once the data has been fetched.

import { Lottie, LottieAnimationData } from "@remotion/lottie";
import { useEffect, useState } from "react";
import {
  cancelRender,
  continueRender,
  delayRender,
  staticFile,
} from "remotion";

const Square = () => {
  const [handle] = useState(() => delayRender("Loading Lottie animation"));

  const [animationData, setAnimationData] =
    useState<LottieAnimationData | null>(null);

  useEffect(() => {
    fetch(staticFile("data.json"))
      .then((data) => data.json())
      .then((json) => {
        setAnimationData(json);
        continueRender(handle);
      })
      .catch((err) => {
        cancelRender(err);
      });
  }, [handle]);

  if (!animationData) {
    return null;
  }

  return <Lottie animationData={animationData} />;
};
