Image Loading Optimization in Nextjs

?? Image Loading Optimization in Next.js:

For your NEXT.js project to run quickly and provide a seamless user experience, image loading optimization is essential.

Large or improperly optimized images can significantly increase website load times, which hurts user engagement and search engine rankings. One method for improving image loading in your NEXT.js application is to use the built-in next/image component.

Depending on the screen resolution of the device, this component automatically optimizes photos by converting them to the next-generation format (WebP) and sending them to the appropriate size.

This can significantly reduce the size of the image file and speed up loading. Here is an example of how to use the next/image component in a NEXT.js app:

Import the next/image component at the top of your component file:

import Image from 'next/image';

Use the Image component to render an image in your component's JSX:

<Image

src="/path/to/image-small.jpg"

srcSet={[

'/path/to/image-small.jpg 400w',

'/path/to/image-medium.jpg 800w',

'/path/to/image-large.jpg 1200w',

]}

sizes={`(max-width: 600px) 400px, 800px`}

alt="A description of the image"

width={1200}

height={600}

quality={75}

/>

Using the IntersectionObserver API to achieve lazy loading is another method for enhancing the loading of images.

Instead of loading all images on the website simultaneously, this API enables you to load images only when they are visible in the viewport. This can save clients' bandwidth and considerably speed up the initial download of your pages.

In conclusion, you can use the next/image component for automatic optimization and the IntersectionObserver API for lazy loading to improve the loading of images in your NEXT.js application. You can enhance the user experience and performance of your app by putting these strategies into practice.
