There are multiple ways to load images dynamically in Next.js without encountering issues with the background URL. Here are a few options:
next/image
component:The next/image
component is a built-in feature of Next.js that provides automatic image optimization, lazy loading, and a responsive image layout. You can use it to load images dynamically by passing the image URL as a prop. Here's an example:
import Image from 'next/image';
//...
function MyComponent({ imageUrl }) {
return (
<>
<div
style={{
backgroundImage: `url(${imageUrl})`,
backgroundRepeat: 'no-repeat',
backgroundSize: 'cover',
}}
>
{/* ... */}
</div>
<Image src={imageUrl} alt="" />
</>
)
}
In this example, the div
element uses the background URL to display the image, while the Image
component loads the image dynamically.
img
HTML tag:If you prefer using the img
HTML tag instead, you can dynamically create an img
element with the image URL as its src
attribute. Here's an example:
function MyComponent({ imageUrl }) {
const imgRef = React.useRef();
React.useEffect(() => {
if (imgRef.current) {
imgRef.current.src = imageUrl;
}
}, [imageUrl]);
return (
<>
<div
style={{
backgroundImage: `url(${imageUrl})`,
backgroundRepeat: 'no-repeat',
backgroundSize: 'cover',
}}
>
{/* ... */}
</div>
<img ref={imgRef} alt="" />
</>
);
}
In this example, we create a ref
to the img
element and update its src
attribute dynamically using the useEffect
hook.
Another option is to load the image dynamically using a CSS module. You can create a CSS module with a class that has a background-image
property and set the value dynamically using JavaScript. Here's an example:
/* styles.module.css */
.myBackgroundImage {
background-image: url('');
}
import styles from './styles.module.css';
function MyComponent({ imageUrl }) {
const divRef = React.useRef();
React.useEffect(() => {
if (divRef.current) {
divRef.current.style.backgroundImage = `url(${imageUrl})`;
}
}, [imageUrl]);
return (
<div ref={divRef} className={styles.myBackgroundImage}>
{/* ... */}
</div>
);
}
In this example, we create a CSS module with a class that has a background-image
property with an empty URL. We use the useEffect
hook to update the background-image
value dynamically, and we apply the class to the div
element using the className
prop.
