Converting native CSS animation to GSAP

[raffael01]

 

I'm trying to convert the following React component from the codepen(Sorry, I couldn't get it to run there) to GSAP.

 

I built it using css animations(with tailwindcss). My code right now depends on the Indextracker state. This tracks which images is visible at the moment. Whenever it changes, the pages refreshes and the tailwind classes change(these set the position/rotation of the element) and  therefor animate it. I know that this is quite janky but that's why i'd like to use GSAP.

 

I'm struggling to figure out where to place my gsap animations:

How can I mix this state management with GSAP?

Can I just put the animations in my forwardClick and backwardClick functions and would they then persist between rerenders?

 

Here's a gif of what it looks like at the moment.

Hi there! I see you're using React -

Proper 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.

 

Since GSAP 3.12, we have the useGSAP() hook (the NPM package is here) that simplifies creating and cleaning up animations in React (including Next, Remix, etc). It's a drop-in replacement for useEffect()/useLayoutEffect(). All the GSAP-related objects (animations, ScrollTriggers, etc.) created while the function executes get collected and then reverted when the hook gets torn down.

 

Here is how it works:

const container = useRef(); // the root level element of your component (for scoping selector text which is optional)

useGSAP(() => {
  // gsap code here...
}, { dependencies: [endX], scope: container }); // config object offers maximum flexibility

Or if you prefer, you can use the same method signature as useEffect():

useGSAP(() => {
  // gsap code here...
}, [endX]); // simple dependency Array setup like useEffect()

This pattern follows React's best practices.

 

We strongly recommend reading the React guide we've put together at https://gsap.com/resources/React/

 

If you still need help, here's a React starter template that you can fork to create a minimal demo illustrating whatever issue you're running into. Post a link to your fork back here and we'd be happy to take a peek and answer any GSAP-related questions you have. Just use simple colored <div> elements in your demo; no need to recreate your whole project with client artwork, etc. The simpler the better.
