How to install with Next.js

So let's get started with installing Gsap + Scrolltrigger with Next.js, we will go through the steps from start to finish and get you started with your first animations.

I would suggest using visual studio code as your coding IDE and also make sure you have the latest version of node installed

Step 1. Install Next.js

Inside Visual Studio code open up your terminal and type the command below to install Next.js

npx create-next-app@latest

The terminal will give you some prompts in order to enable features such as Tailwind CSS and TypeScript. Below are the settings I used for this example.

√ What is your project named? ... lottie-animation
√ Would you like to use TypeScript? ... Yes
√ Would you like to use ESLint? ... Yes
√ Would you like to use Tailwind CSS? ... Yes
√ Would you like to use "src/" directory? ... Yes
√ Would you like to use App Router? (recommended) ... Yes
√ Would you like to customize the default import alias (@/*)? ... No"

Now, let's navigate to the folder where we'll be working. You can do this by either going to 'File' > 'Open Folder' and selecting the project we're working on, or you can use the following commands to navigate to the folder:

cd lottie-animation

Now, let's install the npm packages we need

npm install

How to install Gsap and Scroll Trigger

First, you need to install GSAP in your Next.js project. You can do this using npm or yarn. Run one of the following commands in your terminal:

npm install gsap

Next, we'll import GSAP and ScrollTrigger and register them in our document and add our first animation, you can replace your page.tsx inside your app folder with the below

import React, { useEffect, useRef } from "react";
import { gsap } from "gsap";
import { ScrollTrigger } from "gsap/ScrollTrigger";

export default function Home() {
  const animateRef = useRef(null);
  gsap.registerPlugin(ScrollTrigger); // Register ScrollTrigger

  useEffect(() => {
    let tl = gsap.timeline({
      scrollTrigger: {
        trigger: animateRef.current,
        start: "top 70%", // when the top of the trigger hits the top of the viewport
        end: "+=300", // end after scrolling 300px beyond the start
        scrub: 1, // smooth scrubbing, takes 1 second to "catch up" to the scrollbar
        markers: false, //true if you wish to troubleshoot the document
      },
    });

    // add animations timeline
    tl.from(animateRef.current, { autoAlpha: 0 }).to(animateRef.current, {
      autoAlpha: 1,
    });
  }, []);

  return (
    <div className="w-40 h-40 pt-12 bg-secondary text-center" ref={animateRef}>
        Hello I'm your first scroll trigger animation
    </div>
  );
};

Step 4. Let's run the application
