How can I fix reactivity issues with GSAP in Vue?

To address reactivity issues with GSAP in Vue, ensure that you're using Vue's reactive properties correctly. GSAP manipulates the DOM directly, which can bypass Vue's reactivity system. You might want to use Vue's ref or reactive to wrap your properties.

Can you give me an example of how to use ref with GSAP?

Sure! You can create a ref for your element and then use it in your GSAP animation like this:

import { ref, onMounted } from 'vue';
import { gsap } from 'gsap';

export default {
  setup() {
    const box = ref(null);

    onMounted(() => {
      gsap.to(box.value, { x: 100, duration: 1 });
    });

    return { box };
  }
};

This way, GSAP will animate the element referenced by box.

What if I need to animate multiple elements?

You can use an array of refs for multiple elements. For example:

const boxes = ref([]);

onMounted(() => {
  boxes.value.forEach((box, index) => {
    gsap.to(box, { x: 100 * (index + 1), duration: 1 });
  });
});

Make sure to bind each element in your template to the boxes array.

Are there any performance considerations I should be aware of?

Yes, when using GSAP with Vue, be mindful of the number of animations running simultaneously. Too many can lead to performance issues. Consider using requestAnimationFrame for smoother animations and to avoid jank.
