# GSAP (GreenSock Animation Platform)

#### Professional-grade animation for the modern web

GSAP is a robust JavaScript toolset that turns developers into animation superheroes. Build high-performance animations that work in **every** major browser. Animate CSS, SVG, canvas, React, Vue, WebGL, colors, strings, motion paths, generic objects...anything JavaScript can touch! GSAP's <a href="https://greensock.com/scrolltrigger">ScrollTrigger</a> plugin lets you create jaw-dropping scroll-based animations with minimal code. <a href="https://greensock.com/docs/v3/GSAP/gsap.matchMedia()">gsap.matchMedia()</a> makes building responsive, accessibility-friendly animations a breeze.

No other library delivers such advanced sequencing, reliability, and tight control while solving real-world problems on over 11 million sites. GSAP works around countless browser inconsistencies; your animations **just work**. At its core, GSAP is a high-speed property manipulator, updating values over time with extreme accuracy. It's up to 20x faster than jQuery! See https://greensock.com/why-gsap/ for what makes GSAP so special.

GSAP is completely flexible; sprinkle it wherever you want. **Zero dependencies.**

There are many optional <a href="https://greensock.com/gsap-plugins/">plugins</a> and <a href="https://greensock.com/ease-visualizer/">easing</a> functions for achieving advanced effects easily like <a href="https://greensock.com/docs/v3/Plugins/ScrollTrigger">scrolling</a>, <a href="https://greensock.com/morphsvg">morphing</a>, animating along a <a href="https://greensock.com/docs/v3/Plugins/MotionPathPlugin">motion path</a> or <a href="https://greensock.com/docs/v3/Plugins/Flip">FLIP</a> animations. There's even a handy <a href="https://greensock.com/docs/v3/Plugins/Observer">Observer</a> for normalizing event detection across browsers/devices. 

## Docs &amp; Installation

### CDN
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.2/gsap.min.js"></script>
```
Click the green "Get GSAP Now" button at <a href="https://greensock.com/?download=GSAP-JS">greensock.com</a> for more options and installation instructions, including CDN URLs for various plugins. 

**Every major ad network excludes GSAP from file size calculations** and most have it on their own CDNs, so contact them for the appropriate URL(s). 

### NPM
See the <a href="https://greensock.com/docs/v3/Installation#npm">guide to using GSAP via NPM here</a>.

```javascript
npm install gsap
```
The default (main) file is **gsap.js** which includes most of the eases as well as the core plugins like CSSPlugin, AttrPlugin, SnapPlugin, ModifiersPlugin, and all of the <a href="https://greensock.com/docs/v3/GSAP/UtilityMethods">utility methods</a> like <a href="https://greensock.com/docs/v3/GSAP/UtilityMethods/interpolate()">interpolate()</a>, <a href="https://greensock.com/docs/v3/GSAP/UtilityMethods/mapRange()">mapRange()</a>, etc. 
```javascript
// typical import
import gsap from "gsap";

// get other plugins:
import ScrollTrigger from "gsap/ScrollTrigger";
import Flip from "gsap/Flip";
import Draggable from "gsap/Draggable";

// or all tools are exported from the "all" file (excluding members-only plugins):
import { gsap, ScrollTrigger, Draggable, MotionPathPlugin } from "gsap/all";

// don't forget to register plugins
gsap.registerPlugin(ScrollTrigger, Draggable, Flip, MotionPathPlugin); 
```
The NPM files are ES modules, but there's also a /dist/ directory with <a href="https://www.davidbcalhoun.com/2014/what-is-amd-commonjs-and-umd/">UMD</a> files for extra compatibility.

Download <a href="https://greensock.com/club/">Club GreenSock</a> members-only plugins from your GreenSock.com account and then include them in your own JS payload. There's even a <a href="https://www.youtube.com/watch?v=znVi89_gazE">tarball file you can install with NPM/Yarn</a>. GreenSock has a <a href="https://greensock.com/docs/v3/Installation#private">private NPM registry</a> for members too. Post questions in our <a href="https://greensock.com/forums/">forums</a> and we'd be happy to help.
