    GSAP (GreenSock Animation Platform)

    GSAP - Animate anything

    GSAP is a framework-agnostic JavaScript animation library 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 ScrollTrigger plugin delivers jaw-dropping scroll-based animations with minimal code. gsap.matchMedia() 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 12 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!

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

    There are many optional plugins and easing functions for achieving advanced effects easily like scrolling, morphing, animating along a motion path or FLIP animations. There's even a handy Observer for normalizing event detection across browsers/devices.

    Docs & Installation

    View the full documentation here, including an installation guide.

    CDN

    <script src="https://cdn.jsdelivr.net/npm/gsap@3.12/dist/gsap.min.js"></script>
    

    See JSDelivr's dedicated GSAP page for quick CDN links to the core files/plugins. There are more installation instructions at gsap.com.

    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 guide to using GSAP via NPM here.

    npm install gsap
    

    GSAP's core can animate almost anything including CSS and attributes, plus it includes all of the utility methods like interpolate(), mapRange(), most of the eases, and it can do snapping and modifiers.

    // 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 UMD files for extra compatibility.

    Download Club GSAP members-only plugins from your gsap.com account and then include them in your own JS payload. There's even a tarball file you can install with NPM/Yarn. GSAP has a private NPM registry for members too. Post questions in our forums and we'd be happy to help.

    ScrollTrigger & ScrollSmoother

    If you're looking for scroll-driven animations, GSAP's ScrollTrigger plugin is the new standard. There's a companion ScrollSmoother as well.

    Using React?

    There's a @gsap/react package that exposes a useGSAP() hook which is a drop-in replacement for useEffect()/useLayoutEffect(), automating cleanup tasks. Please read the React guide for details.
