Use Transitions for Non-Urgent Updates
Mark frequent, non-urgent state updates as transitions to maintain UI responsiveness.
Incorrect (blocks UI on every scroll):
function ScrollTracker() {
const [scrollY, setScrollY] = useState(0);
useEffect(() => {
const handler = () => setScrollY(window.scrollY);
window.addEventListener("scroll", handler, { passive: true });
return () => window.removeEventListener("scroll", handler);
}, []);
}
Correct (non-blocking updates):
import { startTransition } from "react";
function ScrollTracker() {
const [scrollY, setScrollY] = useState(0);
useEffect(() => {
const handler = () => {
startTransition(() => setScrollY(window.scrollY));
};
window.addEventListener("scroll", handler, { passive: true });
return () => window.removeEventListener("scroll", handler);
}, []);
}
