Parallax In Next.js using React-Scroll-Parallax 😉

#webdev #javascript #nextjs #tutorial

Parallax a very 🆒 looking effect which can be achieved by changing the speed of the layers in the background 🌃.

Today lets explore how we can make a similar parallax effect in nextjs using a package called react-scroll-parallax 🥰.

https://react-scroll-parallax.damnthat.tv/docs/intro

npm i react-scroll-parallax

lets initialize our project using create-next-app

npx create-next-app --example with-tailwindcss parallax

I made a complete tutorial on youtube you can also check it out

now lets continue our blog

First of all replace all typescript file to JavaScript as the starter template comes configured with typescript 😞 or you can also write normal JavaScript 😲 inside the typescript file not a big deal

So first wrap our Component in _app.js with ParallaxProvider and as we are creating our parallax in horizontal scrolling so we have to mention the scrollAxis='horizontal'

import '../styles/globals.css'
import { ParallaxProvider } from 'react-scroll-parallax'

function MyApp({ Component, pageProps }) {
  return (
    <ParallaxProvider scrollAxis='horizontal'>
      <Component {...pageProps} />
    </ParallaxProvider>
  )
}

export default MyApp

the final effect that we want is something like this 👇🏻

So as there is our main scene and there are some different components like train, cloud and sun and we want to move the cloud and train with relative to our background image and we want to make sun to be static so we will use useRef and useParallax from react-scroll-parallax to achieve this we will create a const target which will store the outermost div and and then we will use useParallax to create the refs for the inner divs and pass speed and targetElement in the useParallax here is the code 👇🏻

import { useParallax } from "react-scroll-parallax";
import React, { useRef } from "react";
import Image from "next/image";

const index = () => {
  const target = useRef(null);
  const train = useParallax({
    speed: 500,
    targetElement: target.current,
  })

  const cloud = useParallax({
    speed: 200,
    targetElement: target.current,
  })

  return (
    <div ref={target} style={{
      backgroundImage: "url('/Scene.png')",
      backgroundSize: "cover",
      backgroundPosition: "center",
      width: '3000px'
    }} className="h-screen">
      <div className="fixed top-10 left-40">
        <Image src="/Sun.png" height={120} width={120} />
      </div>
      <div ref={train.ref} className="absolute"
        style={{
          top: '11vh',
          left: '30vw',
        }}
      >
        <Image src="/Train.png" height={350} width={700} />
      </div>
      <div ref={cloud.ref} className="absolute top-10">
        <Image src="/Cloud.png" height={200} width={1000} />
      </div>
    </div>
  );
}
export default index;
