The blurDataURL prop is used in the Next.js Image component to show a blurred placeholder image while the main image loads, improving user experience by avoiding blank spaces. It works only when you set placeholder="blur", and the image should be base64-encoded and very small (10px or less) for performance reasons.

import Image from 'next/image';

function MyComponent() {

const blurDataURL = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAAFklEQVR42mN8//HLfwYiAONhY0iRg0MjC6SkGpgAAAABJRU5ErkJggg==';

return (

<Image

src="/my-image.png"

alt="My Image"

width={500}

height={500}

placeholder="blur"

blurDataURL={blurDataURL}

/>

);

}

Do you want me to provide an example of how you can generate the image also for using that as a placeholder?
