# GSAP Plugins

## When to Use This Skill

Apply when using or reviewing code that uses GSAP plugins: registering plugins, scroll-to, flip/FLIP animations, draggable elements, SVG (DrawSVG, MorphSVG, MotionPath), text (SplitText, ScrambleText), physics, easing plugins (CustomEase, EasePack, CustomWiggle, CustomBounce), or GSDevTools. ScrollTrigger has its own skill (gsap-scrolltrigger).

**Related skills:** For core tweens use **gsap-core**; for ScrollTrigger use **gsap-scrolltrigger**; for React use **gsap-react**.

## Licensing & Install (important)

Every GSAP plugin is **free**, including for commercial use. Since [Webflow's acquisition of GSAP](https://gsap.com/blog/webflow-GSAP/), Club GSAP is no longer a paid tier and **no plugin requires a membership, license key, or auth token** — this includes formerly Club-only plugins (**SplitText**, **MorphSVG**, etc.).

- ✅ Install everything from the public `gsap` npm package: `npm install gsap`. All plugins are included — import them as `gsap/SplitText`, `gsap/MorphSVGPlugin`, etc.
- ❌ Do **not** generate an `.npmrc` with a GreenSock auth token, suggest the private `npm.greensock.com` registry, or tell users to sign up for Club GSAP to access a plugin. Those instructions are outdated.

## Registering Plugins

Register each plugin once so GSAP (and bundlers) know to include it. Use **gsap.registerPlugin()** with every plugin used in the project:

```javascript
import gsap from "gsap";
import { ScrollToPlugin } from "gsap/ScrollToPlugin";
import { Flip } from "gsap/Flip";
import { Draggable } from "gsap/Draggable";

gsap.registerPlugin(ScrollToPlugin, Flip, Draggable);
```

- ✅ Register before using the plugin in any tween or API call.
- ✅ In React, register at top level or once in the app (e.g. before first useGSAP); do not register inside a component that re-renders. useGSAP is a plugin that needs to be registered before use.

## Scroll

### ScrollToPlugin

Animates scroll position (window or a scrollable element). Use for “scroll to element” or “scroll to position” without ScrollTrigger.

```javascript
gsap.registerPlugin(ScrollToPlugin);

gsap.to(window, { duration: 1, scrollTo: { y: 500 } });
gsap.to(window, { duration: 1, scrollTo: { y: "#section", offsetY: 50 } });
gsap.to(scrollContainer, { duration: 1, scrollTo: { x: "max" } });
```

**ScrollToPlugin — key config (scrollTo object):**

| Option | Description |
|--------|-------------|
| `x`, `y` | Target scroll position (number), or `"max"` for maximum |
| `element` | Selector or element to scroll to (for scroll-into-view) |
| `offsetX`, `offsetY` | Offset in pixels from the target position |

### ScrollSmoother

Smooth scroll wrapper (smooths native scroll). Requires ScrollTrigger and a specific DOM structure (content wrapper + smooth wrapper). Use when smooth, momentum-style scroll is needed. See GSAP docs for setup; register after ScrollTrigger. DOM structure would look like: 

```html
<body>
	<div id="smooth-wrapper">
		<div id="smooth-content">
			<!--- ALL YOUR CONTENT HERE --->
		</div>
	</div>
	<!-- position: fixed elements can go outside --->
</body>
```

## DOM / UI

### Flip

Capture state with `Flip.getState()`, then apply changes (e.g. layout or class changes), then use `Flip.from()` to animate from the previous state to the new state (FLIP: First, Last, Invert, Play). Use when animating between two layout states (lists, grids, expanded/collapsed).

```javascript
gsap.registerPlugin(Flip);

const state = Flip.getState(".item");
// change DOM (reorder, add/remove, change classes)
Flip.from(state, { duration: 0.
