Smooth Interia Scrolling in Nextjs: A Step-by-Step Guide to Elevating Your Website’s UX

Are you tired of jarring and abrupt scrolling on your Nextjs website? Do you want to provide your users with a seamless and smooth browsing experience? Look no further! In this comprehensive guide, we’ll take you through the process of implementing smooth inertia scrolling in Nextjs, step-by-step.

What is Inertia Scrolling?

Inertia scrolling is a technique that simulates the natural scrolling behavior of mobile devices on desktop devices. It allows users to scroll through content with a smooth, fluid motion, giving them a more immersive and engaging experience.

Benefits of Smooth Inertia Scrolling

• Enhanced User Experience (UX): Smooth inertia scrolling creates a seamless and intuitive scrolling experience, making it easier for users to navigate your website.
• Increased Engagement: By providing a more immersive experience, users are more likely to engage with your content and stay on your website for longer periods.
• Better Accessibility: Smooth inertia scrolling can be particularly beneficial for users with disabilities, as it reduces the cognitive load associated with navigating complex layouts.

Setting Up Nextjs for Smooth Inertia Scrolling

Before we dive into the implementation details, make sure you have a basic Nextjs project set up. If you’re new to Nextjs, create a new project using the following command:

npx create-next-app my-app

Once you have your project set up, navigate to the `pages/_app.js` file and add the following code:

import { AppProps } from 'next/app';
import { useState, useEffect } from 'react';

function MyApp({ Component, pageProps }: AppProps) {
  const [scrollPosition, setScrollPosition] = useState(0);

  useEffect(() => {
    window.addEventListener('scroll', () => {
      setScrollPosition(window.pageYOffset);
    });
  }, []);

  return (
    <div className="App">
      <Component {...pageProps} scrollPosition={scrollPosition} />
    </div>
  );
}

export default MyApp;

This code sets up a basic state management system for tracking the scroll position of the user.

Implementing Smooth Inertia Scrolling

Now that we have our basic setup, let’s implement the smooth inertia scrolling functionality. Create a new file called `useInertiaScrolling.js` and add the following code:

import { useState, useEffect, useRef } from 'react';

const useInertiaScrolling = () => {
  const [scrollVelocity, setScrollVelocity] = useState(0);
  const [lastScrollPosition, setLastScrollPosition] = useState(0);
  const scrollingRef = useRef(false);

  const handleScroll = () => {
    const scrollTop = window.pageYOffset;
    const scrollDiff = scrollTop - lastScrollPosition;
    setLastScrollPosition(scrollTop);

    if (scrollingRef.current) {
      setScrollVelocity(scrollDiff / 16);
    } else {
      scrollingRef.current = true;
    }

    requestAnimationFrame(() => {
      if (scrollingRef.current) {
        window.scrollTo(0, scrollTop + scrollVelocity);
        scrollingRef.current = false;
      }
    });
  };

  useEffect(() => {
    window.addEventListener('scroll', handleScroll);
    return () => window.removeEventListener('scroll', handleScroll);
  }, []);

  return scrollVelocity;
};

export default useInertiaScrolling;

This code uses the `useState` and `useEffect` hooks to track the scroll velocity and last scroll position of the user. It also uses the `requestAnimationFrame` function to smoothly update the scroll position.

Integrating Smooth Inertia Scrolling with Your Components

Now that we have our `useInertiaScrolling` hook, let’s integrate it with our components. Create a new file called `InertiaScrollContainer.js` and add the following code:

import { useState, useEffect } from 'react';
import useInertiaScrolling from '../hooks/useInertiaScrolling';

const InertiaScrollContainer = ({ children }) => {
  const scrollVelocity = useInertiaScrolling();

  useEffect(() => {
    document.body.style.overflowY = 'hidden';
    return () => document.body.style.overflowY = 'auto';
  }, []);

  return (
    <div
      className="inertia-scroll-container"
      style={{
        overflowY: 'scroll',
        WebkitOverflowScrolling: 'touch',
      }}
    >
      {children}
    </div>
  );
};

export default InertiaScrollContainer;

This code creates a container component that wraps your content and applies the smooth inertia scrolling functionality.

Using the InertiaScrollContainer Component

Now that we have our `InertiaScrollContainer` component, let’s use it in our pages. Update your `pages/_app.js` file to wrap your content with the `InertiaScrollContainer` component:

import InertiaScrollContainer from '../components/InertiaScrollContainer';

function MyApp({ Component, pageProps }) {
  // ...

  return (
    <InertiaScrollContainer>
      <Component {...pageProps} />
    </InertiaScrollContainer>
  );
}

export default MyApp;

This code wraps your entire application with the smooth inertia scrolling functionality.

Tuning and Optimizing Smooth Inertia Scrolling

While the implementation above provides a basic smooth inertia scrolling experience, you may need to tune and optimize it for your specific use case. Here are some tips to get you started:

1. Adjust the scroll velocity threshold: You can adjust the scroll velocity threshold by modifying the `scrollDiff / 16` calculation in the `useInertiaScrolling` hook. A higher threshold will result in a more aggressive scrolling experience, while a lower threshold will result in a more subtle experience.
2. Add friction to the scrolling experience: You can add friction to the scrolling experience by introducing a damping factor to the `scrollVelocity` calculation. This will help slow down the scrolling motion and create a more realistic experience.
3. Optimize for mobile devices: You can optimize the smooth inertia scrolling experience for mobile devices by adding platform-specific CSS styles. For example, you can add the following CSS to enable momentum-based scrolling on mobile devices:

.inertia-scroll-container {
  -webkit-overflow-scrolling: touch;
}
