Is there a way to provide multiple images to the Image component? In regular HTML, this would look something like this: <img srcset="elva-fairy-480w.jpg 480w, elva-fairy-800w.jpg 800w But I'm not sure how to achieve the same thing in Next.js

Hi @sweet hare. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, Next.js provides a way to handle responsive images using the Image component. The default generated srcset contains 1x and 2x images to support different device pixel ratios. If you want to render a responsive image that stretches with the viewport, you'll need to set sizes as well as style (or className).

Here's an example of how you can render a responsive image using a static import:

import Image from 'next/image'
import me from '../photos/me.jpg'
 
export default function Author() {
 return (
 <Image
 src={me}
 alt="Picture of the author"
 sizes="100vw"
 style={{
 width: '100%',
 height: 'auto',
 }}
 />
 )
}

If the source image is dynamic or a remote URL, you will also need to provide width and height to set the correct aspect ratio of the responsive image:

import Image from 'next/image'
 
export default function Page({ photoUrl }) {
 return (
 <Image
 src={photoUrl}
 alt="Picture of the author"
 sizes="100vw"
 style={{
 width: '100%',
 height: 'auto',
 }}
 width={500}
 height={300}
 />
 )
}

For more complex scenarios like displaying a different image for mobile and desktop (also known as Art Direction), you can use the getImageProps() function to provide different src, width, height, and quality props:

# 
import { getImageProps } from 'next/image'
 
export default function Home() {
 const common = { alt: 'Art Direction Example', sizes: '100vw' }
 const {
 props: { srcSet: desktop },
 } = getImageProps({
 ...common,
 width: 1440,
 height: 875,
 quality: 80,
 src: '/desktop.jpg',
 })
 const {
 props: { srcSet: mobile, ...rest },
 } = getImageProps({
 ...common,
 width: 750,
 height: 1334,
 quality: 70,
 src: '/mobile.jpg',
 })
 
 return (
 <picture>
 <source media="(min-width: 1000px)" srcSet={desktop} />
 <source media="(min-width: 500px)" srcSet={mobile} />
 <img {...rest} style={{ width: '100%', height: 'auto' }} />
 </picture>
 )
}

You can find more information in the Next.js documentation (https://nextjs.org/docs/app/api-reference/components/image#responsive-images).

Can you update that code sample above so that it uses these properties?

 className="object-cover"
          fill={true}
          sizes="(min-width: 1640px) 768px, calc(45vw + 39px)"
          priority={true}
          placeholder={"blur"}
          loading="eager"

Let me check the knowledge base for you. One moment! :books:

Sure, here's how you can update the code sample to include the properties you've mentioned:

import Image from 'next/image'
import me from '../public/me.jpg'
 
export default function Author() {
 return (
 <Image
   src={me}
   alt="Picture of the author"
   className="object-cover"
   fill={true}
   sizes="(min-width: 1640px) 768px, calc(45vw + 39px)"
   priority={true}
   placeholder="blur"
   loading="eager"
   style={{
     width: '100%',
     height: 'auto',
   }}
 />
 )
}

In this example, the Image component will have the class object-cover, which will cause the image to fill its container while maintaining its aspect ratio. The fill prop is set to true, which will cause the image to fill the parent element. The sizes attribute is used for responsive images, and priority is set to true to preload the image. The placeholder prop is set to "blur", which will show a blurred version of the image while it's loading. The loading prop is set to "eager", which will load the image as soon as possible.

Please note that the parent element of the Image component must have a position of relative, fixed, or absolute for the fill prop to work correctly. Also, the parent element should have a display of block. You can find more information in the Next.js documentation (https://nextjs.org/docs/app/api-reference/components/image#fill).

@thorny juniper Keep those CSS attributes but use the getImageProps approach

Sure, here's how you can use the getImageProps function with the properties you've mentioned:

import { getImageProps } from 'next/image'
 
export default function Home() {
 const common = { alt: 'Art Direction Example', sizes: '(min-width: 1640px) 768px, calc(45vw + 39px)', priority: true, placeholder: 'blur', loading: 'eager' }
 const {
 props: { srcSet: desktop },
 } = getImageProps({
 ...common,
 width: 1440,
 height: 875,
 quality: 80,
 src: '/desktop.jpg',
 })
 const {
 props: { srcSet: mobile, ...rest },
 } = getImageProps({
 ...common,
 width: 750,
 height: 1334,
 quality: 70,
 src: '/mobile.jpg',
 })
 
 return (
 <picture>
 <source media="(min-width: 1000px)" srcSet={desktop} />
 <source media="(min-width: 500px)" srcSet={mobile} />
 <img {...rest} className="object-cover" style={{ width: '100%', height: 'auto' }} />
 </picture>
 )
}

In this example, the getImageProps function is used to generate the props for the Image component. The className prop is set to "object-cover", which will cause the image to fill its container while maintaining its aspect ratio. The style prop is used to set the width and height of the image.

Please note that the parent element of the Image component must have a position of relative, fixed, or absolute for the fill prop to work correctly. Also, the parent element should have a display of block. You can find more information in the Next.js documentation (https://nextjs.org/docs/app/api-reference/components/image#getimageprops).

@thorny juniperdo you know what percent of people use ES Lint with Next js?

Hmm, I don't know enough to give you a confident answer yet. The usage statistics of ESLint with Next.js might vary and are not provided in the knowledge sources. However, ESLint is a widely used tool in the JavaScript and React community for maintaining code quality, and Next.js provides integrated support for it. For more specific statistics, you might want to refer to surveys or data from reliable sources.
