## Qué hace

- Explica cómo usar GSAP en Vue, Nuxt, Svelte y SvelteKit siguiendo el ciclo de vida del componente
- Crea las animaciones en `onMounted` / `onMount`, nunca en el setup, porque el DOM aún no existe
- Acota los selectores pasando el contenedor como scope a `gsap.context()`
- Llama a `ctx.revert()` al desmontar para matar tweens y ScrollTriggers y revertir estilos en línea
- Recuerda registrar los plugins una vez a nivel de app, no en cada render

## Cuándo usarla

- Se quiere animación en Vue, Nuxt, Svelte o SvelteKit
- El usuario pregunta por GSAP con `onMounted`, `onMount` u `onDestroy`
- Se revisa código GSAP dentro de un framework de componentes con ciclo de vida

## Cuándo no

- React: usa el skill `gsap-react`

## Qué la activa

- "Anima este componente de Vue con GSAP"
- "¿Cómo limpio los ScrollTriggers al desmontar en Svelte?"
- "Monta esta animación en Nuxt sin fugas"

# GSAP with Vue, Svelte, and Other Frameworks

## When to Use This Skill

Apply when writing or reviewing GSAP code in Vue (or Nuxt), Svelte (or SvelteKit), or other component frameworks that use a lifecycle (mounted/unmounted). For **React** specifically, use **gsap-react** (useGSAP hook, gsap.context()).

**Related skills:** For tweens and timelines use **gsap-core** and **gsap-timeline**; for scroll-based animation use **gsap-scrolltrigger**; for React use **gsap-react**.

## Principles (All Frameworks)

- **Create** tweens and ScrollTriggers **after** the component’s DOM is available (e.g. onMounted, onMount).
- **Kill or revert** them in the **unmount** (or equivalent) cleanup so nothing runs on detached nodes and there are no leaks.
- **Scope selectors** to the component root so `.box` and similar only match elements inside that component, not the rest of the page.

## Vue 3 (Composition API)

Use **onMounted** to run GSAP after the component is in the DOM. Use **onUnmounted** to clean up.

```javascript
import { onMounted, onUnmounted, ref } from "vue";
import { gsap } from "gsap";
import { ScrollTrigger } from "gsap/ScrollTrigger";
gsap.registerPlugin(ScrollTrigger); // once per app, e.g. in main.js

export default {
  setup() {
    const container = ref(null);
    let ctx;

    onMounted(() => {
      if (!container.value) return;
      ctx = gsap.context(() => {
        gsap.to(".box", { x: 100, duration: 0.6 });
        gsap.from(".item", { autoAlpha: 0, y: 20, stagger: 0.1 });
      }, container.value);
    });

    onUnmounted(() => {
      ctx?.revert();
    });

    return { container };
  }
};
```

- ✅ **gsap.context(scope)** — pass the container ref (e.g. `container.value`) as the second argument so selectors like `.item` are scoped to that root. All animations and ScrollTriggers created inside the callback are tracked and reverted when **ctx.revert()** is called.
- ✅ **onUnmounted** — always call **ctx.revert()** so tweens and ScrollTriggers are killed and inline styles reverted.

## Vue 3 (script setup)

Same idea with `<script setup>` and refs:

```javascript
<script setup>
import { onMounted, onUnmounted, ref } from "vue";
import { gsap } from "gsap";
import { ScrollTrigger } from "gsap/ScrollTrigger";

const container = ref(null);
let ctx;

onMounted(() => {
  if (!container.value) return;
  ctx = gsap.context(() => {
    gsap.to(".box", { x: 100 });
    gsap.from(".item", { autoAlpha: 0, stagger: 0.1 });
  }, container.value);
});

onUnmounted(() => {
  ctx?.revert();
});
</script>

<template>
  <div ref="container">
    <div class="box">Box</div>
    <div class="item">Item</div>
  </div>
</template>
```

## Svelte

Use **onMount** to run GSAP after the DOM is ready. Use the **returned cleanup function** from onMount (or track the context and clean up in a reactive block / component destroy) to revert. Svelte 5 uses a different lifecycle; the same principle applies: create in “mounted” and revert in “destroyed.”

```javascript
<script>
  import { onMount } from "svelte";
  import { gsap } from "gsap";
  import { ScrollTrigger } from "gsap/ScrollTrigger";

  let container;

  onMount(() => {
    if (!container) return;
    const ctx = gsap.context(() => {
      gsap.to(".box", { x: 100 });
      gsap.from(".item", { autoAlpha: 0, stagger: 0.1 });
    }, container);
    return () => ctx.revert();
  });
</script>

<div bind:this={container}>
  <div class="box">Box</div>
  <div class="item">Item</div>
</div>
```

- ✅ **bind:this={container}** — get a reference to the root element so you can pass it to **gsap.context(scope)**.
- ✅ **return () => ctx.revert()** — Svelte’s onMount can return a cleanup function; call **ctx.revert()** there so cleanup runs when the component is destroyed.

## Scoping Selectors

Do not use global selectors that can match elements outside the current component. Always pass the **scope** (container element or ref) as the second argument to **gsap.context(callback, scope)** so that any selector run inside the callback is limited to that subtree.

- ✅ **gsap.context(() => { gsap.to(".box", ...) }, containerRef)** — `.box` is only searched inside `containerRef`.
- ❌ Running **gsap.to(".box", ...)** without a context scope in a component can affect other instances or the rest of the page.

## ScrollTrigger Cleanup

ScrollTrigger instances are created when you use the `scrollTrigger` config on a tween/timeline or **ScrollTrigger.create()**. They are **included** in **gsap.context()** and reverted when you call **ctx.revert()**. So:

- Create ScrollTriggers inside the same **gsap.context()** callback you use for tweens.
- Call **ScrollTrigger.refresh()** after layout changes (e.g. after data loads) that affect trigger positions; in Vue/Svelte that often means after the DOM updates (e.g. nextTick in Vue, tick in Svelte, or after async content load).

## When to Create vs Kill

| Lifecycle        | Action |
|-----------------|--------|
| **Mounted**      | Create tweens and ScrollTriggers inside **gsap.context(scope)**. |
| **Unmount / Destroy** | Call **ctx.revert()** so all animations and ScrollTriggers in that context are killed and inline styles reverted. |

Do not create GSAP animations in the component’s setup or in a synchronous top-level script that runs before the root element exists. Wait for **onMounted** / **onMount** (or equivalent) so the container ref is in the DOM.

## Do Not

- ❌ Create tweens or ScrollTriggers before the component is mounted (e.g. in setup without onMounted); the DOM nodes may not exist yet.
- ❌ Use selector strings without a **scope** (pass the container to gsap.context() as the second argument) so selectors don’t match elements outside the component.
- ❌ Skip cleanup; always call **ctx.revert()** in onUnmounted / onMount’s return so animations and ScrollTriggers are killed when the component is destroyed.
- ❌ Register plugins inside a component body that runs every render (it doesn't hurt anything, it's just wasteful); register once at app level.
