And the onClick handler of the button is tied to the toggleMenu function. Now that we have gotten a feel of some the basic building blocks of GSAP, let’s see how we could build a complete animation in a typical React app in the next section. import React, {useRef, useEffect } from "react"; // importing the main GSAP package and the specific feature being used import gsap, {TimelineMax } from "gsap"; // importing individual plugins import TextPlugin from "gsap/TextPlugin"; import EasePack from "gsap/EasePack"; function Tagline {// create a ref to be used to store the timeline … In this series we are taking a look at the basics of adding the very popular animation library; GSAP, into our Create React App. To make the right edge stick to the scroll bar we passed right center value to the transformOrigin property, we also set the force3D property to true in other to improve the performance. If you already know the fundamentals of GSAP, you can skip this section and jump straight to the project section, where we’ll make a landing page skew while scrolling. Vue.js is a Javascript framework that is both powerful and easy to pick up. Now, we have updated our timeline. You can check out more benefits on GSAP or see what Sarah Drasner as to say about it here. So how this all works together is you need to start by importing GSAP just like you would import any other package: However, depending on what you're doing, you might only need to import the specific feature you're using, such as TimelineMax: Then you can write your code for the timeline as you normally would, using the tl.current ref to store everything and either writing the code directly in useEffect() or referencing a function containing it in useEffect(). To take the animation created and actually tie it to one of your elements, the ref needs to be referenced by that object. Head over to Animate.js and paste this code into it. More about Check out the finished project on codesandbox. In the code samples below notice that the duration() method can be used in exactly the same way for both the tween and timeline. A guide to increasing conversion and driving sales. Now that we have gotten a feel of some the basic building blocks of GSAP, let’s see how we could build a complete animation in a typical React app in the next section. With that, we’ve got our menu animated. Note: Whenever we’re animating positional properties, such as left and top, we must ensure that the elements concerned must have a CSS position property of either relative, absolute, or fixed. gsap.to('.ball', { duration: 1, x: 200, scale: 2 }) See the Pen Greensock Tutorial 1 by Sarah Drasner on CodePen.
