$ npm i use-listen-on-animation-frameLibrary provides 2 hooks which are useAnimationFrame, useListenOnAnimationFrame. See Usage, API and Advanced usage for more.
Run function on every animation frame
import React, { useCallback, useState } from "react";
import { useAnimationFrame } from "use-listen-on-animation-frame";
const Component = () => {
const [date, setDate] = useState(new Date());
const syncDate = useCallback(() => {
setDate(new Date());
}, []);
useAnimationFrame(syncDate);
return <div>{date}</div>;
};Run function once on every animation frame, and apply multiple listeners to it. Stop and start function & listeners when you want.
import React, { useState } from "react";
import { useListenOnAnimationFrame } from "use-listen-on-animation-frame";
const getCostlyRandomNumber = () => {
const random = Math.random() * 300;
let counter = 0;
for (; counter < random; counter++) {
counter++;
}
return counter;
};
const Component = () => {
const [number, setNumber] = useState(0);
const [addListener, _removeListener, stop, start] = useListenOnAnimationFrame(
getCostlyRandomNumber,
{ autoStart: false } // optional
);
useEffect(() => {
addListener((thisFrameRandom, _previousFrameRandom) => {
setNumber(thisFrameRandom);
});
addListener((thisFrameRandom) => {
// do something;
});
addListener((thisFrameRandom) => {
for (let i = 0; i < thisFrameRandom; i++) {
// do something
}
});
}, [addListener]);
useEffect(() => {
if (somethingBadHappened) {
stop();
}
}, [stop, somethingBadHappened]);

<span>{number}</span>
<AnotherComponent
addFrameListener={addListener}

</div>
);
};
