GSAP 动画开发助手
When to Use This Skill
Use this skill when the user asks for frontend animation work involving JavaScript, GSAP, React, Vue, Svelte, vanilla JS, scroll-driven animation, timeline sequencing, SVG animation, plugin usage, or animation performance review.
Typical triggers:
- "帮我做一个页面动效"
- "用 GSAP 实现动画"
- "实现滚动触发动画 / parallax / pin / scrub"
- "给 React/Vue/Svelte 组件加动画"
- "用 timeline 编排多步骤动画"
- "检查这段动画代码有没有内存泄漏或性能问题"
- "从 CSS animation 改成可控的 JS 动画"
- "SplitText / MorphSVG / Flip / Draggable / ScrollSmoother 怎么用"
If the user asks for a JavaScript animation library but does not specify one, recommend GSAP when they need timelines, scroll-driven animation, SVG animation, or framework-agnostic control. If the user already chose another library, respect that choice.
Before Answering
- Identify the user's framework: vanilla JS, React, Next.js, Vue, Nuxt, Svelte, or unknown.
- Identify the animation type: simple tween, sequence/timeline, scroll-driven effect, plugin use, framework integration, or performance/debugging.
- Read the relevant reference file before giving detailed API guidance.
- Prefer small, production-safe examples with cleanup logic.
- Keep GSAP API names and code in English; explain behavior in the user's language.

Core Guidance
- Prefer transform aliases like
x, y, scale, rotation, and autoAlpha over layout-heavy properties where possible.
- Use
gsap.timeline() for sequenced animations instead of chaining many delays.
- Register plugins once with
gsap.registerPlugin(...).
- For scroll-driven animation, use
ScrollTrigger and call ScrollTrigger.refresh() after meaningful layout changes.
- For React, prefer
@gsap/react useGSAP() with a scope, or gsap.context() with cleanup.
- For Vue/Svelte, create animations after mount and kill/revert them on unmount.
- Respect
prefers-reduced-motion; use gsap.matchMedia() when responsive/reduced-motion behavior matters.
- Do not leave invisible elements blocking clicks; prefer
autoAlpha for fade in/out.
Common Patterns
Basic Tween
import { gsap } from "gsap";
gsap.to(".box", {
x: 100,
autoAlpha: 1,
duration: 0.6,
ease: "power2.inOut"
});
Timeline
const tl = gsap.timeline({ defaults: { duration: 0.5, ease: "power2.out" } });
tl.to(".title", { y: 0, autoAlpha: 1 })
.to(".card", { y: 0, autoAlpha: 1, stagger: 0.08 }, "-=0.2");
ScrollTrigger
import { gsap } from "gsap";
import { ScrollTrigger } from "gsap/ScrollTrigger";
gsap.registerPlugin(ScrollTrigger);
gsap.to(".panel", {
xPercent: -100,
scrollTrigger: {
trigger: ".section",
start: "top top",
end: "bottom top",
scrub: true,
pin: true
}
});
React Cleanup
import { useRef } from "react";
import { gsap } from "gsap";
import { useGSAP } from "@gsap/react";
gsap.registerPlugin(useGSAP);
export function Hero() {
const container = useRef(null);
useGSAP(() => {
gsap.from(".headline", { y: 24, autoAlpha: 0, duration: 0.6 });
}, { scope: container });
return <section ref={container}><h1 className="headline">Hello</h1></section>;
}
Output Requirements
When generating code:
- State required imports and plugin registration.
- Include cleanup logic for framework components.
- Avoid global selectors in component code unless scoped.
- Prefer concise code that can be pasted into a user's project.
- Mention required package install only when needed:
npm install gsap @gsap/react for React usage.
- Do not claim to run or preview animations unless actually executed in the user's project.
When reviewing code:
- Check cleanup on unmount.
- Check duplicate plugin registration or missing plugin registration.
- Check layout-thrashing properties when transform alternatives exist.
- Check ScrollTrigger refresh/kill/revert behavior.
- Check accessibility and reduced-motion handling when animation is prominent.
Safety and Boundaries
- GSAP is a frontend animation library. Do not perform account login, payment, scraping, destructive filesystem operations, or external publishing as part of animation guidance.
- GSAP and its plugins are free via the public
gsap npm package. Do not ask users for Club GSAP credentials, private registry tokens, or .npmrc auth configuration.
- Brand assets from the source repository should only be used according to GreenSock's branding expectations.

47## Core Guidance

49- Prefer transform aliases like `x`, `y`, `scale`, `rotation`, and `autoAlpha` over layout-heavy properties where possible.
50- Use `gsap.timeline()` for sequenced animations instead of chaining many delays.
51- Register plugins once with `gsap.registerPlugin(...)`.
52- For scroll-driven animation, use `ScrollTrigger` and call `ScrollTrigger.refresh()` after meaningful layout changes.
53- For React, prefer `@gsap/react` `useGSAP()` with a scope, or `gsap.context()` with cleanup.
54- For Vue/Svelte, create animations after mount and kill/revert them on unmount.
55- Respect `prefers-reduced-motion`; use `gsap.matchMedia()` when responsive/reduced-motion behavior matters.
