gsap

What is gsap?

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.

What are gsap's main functionalities?

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 });

velocity-animate

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

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.
