Hi there! I see you're using React -

Proper animation cleanup is very important with frameworks, but especially with React. React 18 runs in strict mode locally by default which causes your useEffect() and useLayoutEffect() to get called TWICE.

 

In GSAP 3.11, we introduced a new gsap.context() feature that helps make animation cleanup a breeze. All you need to do is wrap your code in a context call. All GSAP animations and ScrollTriggers created within the function get collected up in that context so that you can easily revert() ALL of them at once.

 

Here's the structure:

// typically it's best to useLayoutEffect() instead of useEffect() to have React render the initial state properly from the very start.
useLayoutEffect(() => {
  let ctx = gsap.context(() => {
    // all your GSAP animation code here
  });
  return () => ctx.revert(); // <- cleanup!
}, []);

This pattern follows React's best practices, and one of the React team members chimed in here if you'd like more background.

We strongly recommend reading the React information we've put together at https://greensock.com/react
