What this skill does


# 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 Those instructions are outdated.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: 0.5, ease: "power2.inOut" });
```

**Flip — key config (Flip.from vars):**

| Option | Description |
|--------|-------------|
| `absolute` | Use `position: absolute` during the flip (default: `false`) |
| `nested` | When true, only the first level of children is measured (better for nested transforms) |
| `scale` | When true, scale elements to fit (avoids stretch); default `true` |
| `simple` | When true, only position/scale are animated (faster, less accurate) |
| `duration`, `ease` | Standard tween options |

### Draggable

Makes elements draggable, spinnable, or throwable with mouse/touch. Use for sliders, cards, reorderable lists, or any drag interaction.

```javascript
gsap.registerPlugin(Draggable, InertiaPlugin);

Draggable.create(".box", { type: "x,y", bounds: "#container", inertia: true });
Draggable.create(".knob", { type: "rotation" });
```

**Draggable — key config options:**

| Option | Description |
|--------|-------------|
| `type` | `"x"`, `"y"`, `"x,y"`, `"rotation"`, `"scroll"` |
| `bounds` | Element, selector, or `{ minX, maxX, minY, maxY }` to constrain drag |
| `inertia` | `true` to enable throw/momentum (requires InertiaPlugin) |
| `edgeResistance` | 0–1; resistance when dragging past bounds |
| `cursor` | CSS cursor during drag |
| `onDragStart`, `onDrag`, `onDragEnd` | Callbacks; receive event and target |
| `onThrowUpdate`, `onThrowComplete` | Callbacks when inertia is active |

### Inertia (InertiaPlugin)

Works with Draggable for momentum after release, or track the inertia/velocity of any property of any object so that it can then seamlessly glide to a stop using a simple tween. Register with Draggable when using `inertia: true`:

```javascript
gsap.registerPlugin(Draggable, InertiaPlugin);
Draggable.create(".box", { type: "x,y", inertia: true });
```

Or track velocity of a property: 
```javascript
InertiaPlugin.track(".box", "x");
```

Then use `"auto"` to continue the current velocity and glide to a stop: 

```javascript
gsap.to(obj, { inertia: { x: "auto" } });
```

### Observer

Normalizes pointer and scroll input across devices. Use for swipe, scroll direction, or custom gesture logic without tying directly to scroll position like ScrollTrigger.

```javascript
gsap.registerPlugin(Observer);

Observer.create({
  target: "#area",
  onUp: () => {},
  onDown: () => {},
  onLeft: () => {},
  onRight: () => {},
  tolerance: 10
});
```

**Observer — key config options:**

| Option | Description |
|--------|-------------|
| `target` | Element or selector to observe |
| `onUp`, `onDown`, `onLeft`, `onRight` | Callbacks when swipe/scroll passes tolerance in that direction |
| `tolerance` | Pixels before direction is detected; default 10 |
| `type` | `"touch"`, `"pointer"`, or `"wheel"` (default: `"touch,pointer"`) |

## Text

### SplitText

Splits an element’s text into characters, words, and/or lines (each in its own element) for staggered or per-unit animation. Use when animating text character-by-character, word-by-word, or line-by-line. Returns an instance with **chars**, **words**, **lines** (and **masks** when `mask` is set). Restore original markup with **revert()** or let **gsap.context()** revert. Integrates with **gsap.context()**, **matchMedia()**, and **useGSAP()**. API: **SplitText.create(target, vars)** (target = selector, element, or array).

```javascript
gsap.registerPlugin(SplitText);

const split = SplitText.create(".heading", { type: "words, chars" });
gsap.from(split.chars, { opacity: 0, y: 20, stagger: 0.03, duration: 0.4 });
// later: split.revert() or let gsap.context() cleanup revert
```

With **onSplit()** (v3.13.0+), animations run on each split and on re-split when **autoSplit** is used; returning a tween/timeline from **onSplit()** lets SplitText clean up and sync progress on re-split:

```javascript
SplitText.create(".split", {
  type: "lines",
  autoSplit: true,
  onSplit(self) {
    return gsap.from(self.lines, { y: 100, opacity: 0, stagger: 0.05, duration: 0.5 });
  }
});
```

**SplitText — key config (SplitText.create vars):**

| Option | Description |
|--------|-------------|
| **type** | Comma-separated: `"chars"`, `"words"`, `"lines"`. Default `"chars,words,lines"`. Only split what is needed (e.g. `"words, chars"` if not using lines) for performance. Avoid chars-only without words/lines or use **smartWrap:
