GSAP (GreenSock Animation Platform) is a powerful JavaScript library for creating high-performance animations that work in all major browsers. It is widely used for animating web elements, SVGs, and more, providing a rich set of features for developers to create complex animations with ease.
Basic Tweening
This feature allows you to animate any property of an element over a specified duration. In this example, the element with the class 'element' will move 100 pixels to the right over 1 second.
gsap.to('.element', { duration: 1, x: 100 });Timeline Animations
Timelines allow you to sequence multiple animations. In this example, 'element1' will move 100 pixels to the right, and then 'element2' will move 100 pixels down, each over 1 second.
const tl = gsap.timeline();
tl.to('.element1', { duration: 1, x: 100 })
.to('.element2', { duration: 1, y: 100 });Stagger Animations
Staggering allows you to animate multiple elements with a delay between each start. In this example, each element with the class 'elements' will move 100 pixels to the right, starting 0.2 seconds after the previous one.
gsap.to('.elements', { duration: 1, x: 100, stagger: 0.2 });ScrollTrigger
ScrollTrigger allows you to create animations that are triggered by scrolling. In this example, the element with the class 'element' will move 100 pixels to the right when it enters the viewport.
gsap.registerPlugin(ScrollTrigger);
gsap.to('.element', { scrollTrigger: '.element', x: 100 });Anime.js is a lightweight JavaScript animation library with a simple, yet powerful API. It supports CSS properties, SVG, DOM attributes, and JavaScript Objects. Compared to GSAP, Anime.js is more lightweight but may lack some of the advanced features and plugins that GSAP offers.
Velocity is an animation engine with the same API as jQuery's $.animate(). It works with and without jQuery. Velocity is known for its performance and ease of use, but it doesn't offer as many features and plugins as GSAP.
Popmotion is a functional, flexible JavaScript animation library. It provides a range of tools for creating animations and interactions. While it is highly modular and flexible, it may require more setup and understanding compared to GSAP's more straightforward API.

Animate CSS, SVG, canvas, React, Vue, WebGL, colors, strings, motion paths, generic objects...anything JavaScript can touch! GSAP's ScrollTrigger plugin lets you create jaw-dropping scroll-based animations with minimal code. No other library delivers such advanced sequencing, reliability, and tight control while solving real-world problems on over 10 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 plugins and easing functions for achieving advanced effects easily like scrolling, morphing, or animating along a motion path.

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).
See the guide to using GSAP via NPM here.
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 utility methods like interpolate(), mapRange(), etc.
// typical import
import gsap from "gsap";
// or get other plugins:
import ScrollTrigger from "gsap/ScrollTrigger";
import Draggable from "gsap/Draggable";
// or all tools are exported from the "all" file (excluding bonus plugins):
import { gsap, ScrollTrigger, Draggable, MotionPathPlugin } from "gsap/all";
// don't forget to register plugins
gsap.registerPlugin(ScrollTrigger, Draggable, MotionPathPlugin);
The NPM files are ES modules, but there's also a /dist/ directory with UMD files for extra compatibility.
