| 3 | ## When to Use This Skill |
| 4 | |
| 5 | 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()). |
| 6 | |
| 7 | **Related skills:** For tweens and timelines use **gsap-core** and **gsap-timeline**; for scroll-based animation use **gsap-scrolltrigger**; for React use **gsap-react**. |
| 8 | |
| 9 | ## Principles (All Frameworks) |
| 10 | |
| 11 | - **Create** tweens and ScrollTriggers **after** the component’s DOM is available (e.g. onMounted, onMount). |
| 12 | - **Kill or revert** them in the **unmount** (or equivalent) cleanup so nothing runs on detached nodes and there are no leaks. |
| 13 | - **Scope selectors** to the component root so `.box` and similar only match elements inside that component, not the rest of the page. |
| 14 | |
| 15 | ## Vue 3 (Composition API) |
| 16 | |
| 17 | See `examples/vue/` for a runnable Vite + Vue 3 project demonstrating these patterns. |
| 18 | |
| 19 | Use **onMounted** to run GSAP after the component is in the DOM. Use **onUnmounted** to clean up. |
| 20 | |
| 21 | ```javascript |
| 22 | import { onMounted, onUnmounted, ref } from "vue"; |
| 23 | import { gsap } from "gsap"; |
| 24 | import { ScrollTrigger } from "gsap/ScrollTrigger"; |
| 25 | gsap.registerPlugin(ScrollTrigger); // once per app, e.g. in main.js |
| 26 | |
| 27 | export default { |
| 28 | setup() { |
| 29 | const container = ref(null); |
| 30 | let ctx; |
| 31 | |
| 32 | onMounted(() => { |
| 33 | if (!container.value) return; |
| 34 | ctx = gsap.context(() => { |
| 35 | gsap.to(".box", { x: 100, duration: 0.6 }); |
| 36 | gsap.from(".item", { autoAlpha: 0, y: 20, stagger: 0.1 }); |
| 37 | }, container.value); |
| 38 | }); |
| 39 | |
| 40 | onUnmounted(() => { |
| 41 | ctx?.revert(); |
| 42 | }); |
| 43 | |
| 44 | return { container }; |
| 45 | }, |
| 46 | }; |
| 47 | ``` |
| 48 | |
| 49 | - ✅ **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. |
| 50 | - ✅ **onUnmounted** — always call **ctx.revert()** so tweens and ScrollTriggers are killed and inline styles reverted. |
| 51 | |
| 52 | ## Vue 3 (script setup) |
| 53 | |
| 54 | Same idea with `<script setup>` and refs: |
| 55 | |
| 56 | ```javascript |
| 57 | <script setup> |
| 58 | import { onMounted, onUnmounted, ref } from "vue"; |
| 59 | import { gsap } from "gsap"; |
| 60 | import { ScrollTrigger } from "gsap/ScrollTrigger"; |
| 61 | |
| 62 | const container = ref(null); |
| 63 | let ctx; |
| 64 | |
| 65 | onMounted(() => { |
| 66 | if (!container.value) return; |
| 67 | ctx = gsap.context(() => { |
| 68 | gsap.to(".box", { x: 100 }); |
| 69 | gsap.from(".item", { autoAlpha: 0, stagger: 0.1 }); |
| 70 | }, container.value); |
| 71 | }); |
| 72 | |
| 73 | onUnmounted(() => { |
| 74 | ctx?.revert(); |
| 75 | }); |
| 76 | </script> |
| 77 | |
| 78 | <template> |
| 79 | <div ref="container"> |
| 80 | <div class="box">Box</div> |
| 81 | <div class="item">Item</div> |
| 82 | </div> |
| 83 | </template> |
| 84 | ``` |
| 85 | |
| 86 | ## Nuxt 4 |
| 87 | |
| 88 | > See `examples/nuxt/` for a runnable Nuxt 4 project with plugin registration, lazy loading, and SSR-safe patterns. |
| 89 | |
| 90 | Use a **reusable composable** to register GSAP Plugins and also to lazy load Plugins that are not extensively used in your application: |
| 91 | |
| 92 | ```typescript |
| 93 | // composables/useGSAP.ts |
| 94 | import { gsap } from "gsap"; |
| 95 | import { ScrollTrigger } from "gsap/ScrollTrigger"; |
| 96 | |
| 97 | const PLUGINS = [ |
| 98 | "CSSRulePlugin", |
| 99 | "CustomBounce", |
| 100 | "CustomEase", |
| 101 | "CustomWiggle", |
| 102 | "Draggable", |
| 103 | "DrawSVGPlugin", |
| 104 | "EaselPlugin", |
| 105 | "EasePack", |
| 106 | "Flip", |
| 107 | "GSDevTools", |
| 108 | "InertiaPlugin", |
| 109 | "MorphSVGPlugin", |
| 110 | "MotionPathHelper", |
| 111 | "MotionPathPlugin", |
| 112 | "Observer", |
| 113 | "Physics2DPlugin", |
| 114 | "PhysicsPropsPlugin", |
| 115 | "PixiPlugin", |
| 116 | "ScrambleTextPlugin", |
| 117 | "ScrollSmoother", |
| 118 | "ScrollToPlugin", |
| 119 | "ScrollTrigger", |
| 120 | "SplitText", |
| 121 | "TextPlugin", |
| 122 | ] as const; |
| 123 | |
| 124 | type Plugins = (typeof PLUGINS)[number]; |
| 125 | |
| 126 | // In order to dynamically load all the GSAP plugins |
| 127 | const pluginMap = { |
| 128 | CustomEase: () => import("gsap/CustomEase"), |
| 129 | Draggable: () => import("gsap/Draggable"), |
| 130 | CSSRulePlugin: () => import("gsap/CSSRulePlugin"), |
| 131 | EaselPlugin: () => import("gsap/EaselPlugin"), |
| 132 | EasePack: () => import("gsap/EasePack"), |
| 133 | Flip: () => import("gsap/Flip"), |
| 134 | MotionPathPlugin: () => import("gsap/MotionPathPlugin"), |
| 135 | Observer: () => import("gsap/Observer"), |
| 136 | PixiPlugin: () => import("gsap/PixiPlugin"), |
| 137 | ScrollToPlugin: () => import("gsap/ScrollToPlugin"), |
| 138 | ScrollTrigger: () => import("gsap/ScrollTrigger"), |
| 139 | TextPlugin: () => import("gsap/TextPlugin"), |
| 140 | DrawSVGPlugin: () => import("gsap/DrawSVGPlugin"), |
| 141 | Physics2DPlugin: () => import("gsap/Physics2DPlugin"), |
| 142 | PhysicsPropsPlugin: () => import("gsap/PhysicsPropsPlugin"), |
| 143 | ScrambleTextPlugin: () => import("gsap/ScrambleTextPlugin"), |
| 144 | CustomBounce: () => import("gsap/CustomBou |
