React Scroll Animations: Scroll-Linked & Viewport-Triggered Motion
Developing production React scroll animations has traditionally meant choosing between bloated third-party JavaScript runtimes or complex IntersectionObserver boilerplate that drops frames during rapid page scrolling. ExodeUI redefines scroll-linked motion by linking scroll progress directly to GPU timeline interpolation. You can pin full-screen visual stages, orchestrate layered parallax depths, and reveal content dynamically as the user travels down the page, all while keeping the browser main thread completely free for business logic.
Runnable ExodeUI React Code Example
Production ReadyImport the ExodeUICanvas component directly into your React application tree. Wire states, triggers, and parameters declaratively:
import React, { useEffect, useRef } from 'react';
import { ExodeUICanvas } from 'exodeui';
export function ScrollRevealScene() {
const canvasRef = useRef(null);
useEffect(() => {
const handleScroll = () => {
const progress = Math.min(window.scrollY / 800, 1.0);
if (canvasRef.current) {
canvasRef.current.setInputValue('scrollProgress', progress);
}
};
window.addEventListener('scroll', handleScroll, { passive: true });
return () => window.removeEventListener('scroll', handleScroll);
}, []);
return (
<div className="scroll-stage" style={{ height: '200vh' }}>
<ExodeUICanvas
ref={canvasRef}
src="/scenes/scroll-scene.json"
inputs={{ "scrollProgress": 0 }}
/>
</div>
);
}Frequently Asked Questions about react scroll animations
How does ExodeUI guarantee 60fps/120fps during heavy scroll animations?
ExodeUI utilizes passive scroll listeners and off-thread WebGL/canvas rendering pipelines, preventing DOM layout thrashing and paint bottlenecks.
Can ExodeUI pin elements to the viewport like GSAP ScrollTrigger?
Yes. ExodeUI integrates sticky pinning states that hold sections in place while scrubbing internal scene timelines based on scroll travel distance.
Is scroll progress normalized across different browser trackpads and mice?
Yes. ExodeUI normalizes delta values across Windows mousewheels, Apple trackpads, and mobile touch inertia to provide consistent velocity.
