Mastering GSAP Animations in Modern React Applications

GSAP (GreenSock Animation Platform) is incredibly powerful for complex, high-performance web animations. While CSS transitions are great for simple hover states, GSAP shines when you need precise timeline control or physics-based movements.

In this guide, we'll look at why you should use useGSAP, how to avoid common React strict mode pitfalls with animations, and techniques for creating custom cursors that react contextually to elements on the page.

One of the best patterns I've discovered is isolating animation logic into dedicated hooks or components. This keeps your UI functional and your animation timeline pristine.

Here's a quick example of a custom cursor with GSAP:

import { useGSAP } from "@gsap/react";
import gsap from "gsap";
 
export function Cursor() {
  useGSAP(() => {
    gsap.to('.cursor', { scale: 2, duration: 0.3 });
  });
 
  return <div className="cursor w-4 h-4 rounded-full bg-white fixed z-50 pointer-events-none" />;
}

And that's how you do `inline code` without breaking standard layouts!
