Is there a way to use an image URL fetched from an API as a background image with tailwindcss, or should I resort to using the styles attribute instead?
Instead of relying solely on a style attribute, I have discovered an alternative solution.
<div
style={{'--image-url': `url(${fetchedUrl})`}}
className='bg-[image:var(--image-url)]'>
<!-- ... -->
</div>
This method works flawlessly.
Although it may seem laborious, it can be utilized to trigger background image changes on hover, focus, and other interactive events that cannot be achieved with a style attribute alone.
className='hover:bg-[image:var(--image-url)] focus:bg-[image:var(--image-url)] ...'
This innovative use of custom properties opens up possibilities for incorporating dynamic values in Tailwind CSS, such as colors retrieved from an external API.
<div
style={{'--color': fetchedColor}}
className='text-[color:var(--color)]'>
<!-- ... -->
</div>
In my opinion, the most effective solution would be to follow your recommendation and utilize a style attribute. Tailwind CSS is primarily focused on applying pre-defined styles to elements through class names, rather than handling dynamic data directly. The only alternative to using the style attribute would involve conditionally adding or removing class names based on certain conditions, which would necessitate prior knowledge of the image URL—defeating the purpose of fetching it from an API.
Here's how I would approach it:
style={{backgroundImage: `url(${fetchedImgSrc})`}}Update: Interestingly, it appears that Tailwind can achieve something akin to the code snippet above according to https://tailwindcss.com/docs/background-image. The corresponding code example looks like this:
<div class="bg-[url('/img/hero-pattern.svg')]">
<!-- ... -->
</div>To set a background image using Style:
const bagImage = "https://via.placeholder.com/500"
<div
className="something-else"
style={{backgroundImage: `url(${bagImage})`}}
</div>
Despite the most recent implementation of arbitrary values, it appears that Dynamic URLs are still causing issues. In my situation, the image was being pulled from an API. In such cases, it's best to stick with the style attribute.
In the following solution, bgImage is passed as a prop.
<div className={`justify-center bg-no-repeat bg-cover bg-center rounded-lg`}
style={{ backgroundImage: `url(${bgImage})`}} >
<!-- Children here-->
</div>
If you're facing the same issue in 2023, here's how I resolved it using tailwind version ^4.0.15. I simply relocated the image to the assets folder and referenced it in my tailwind.config.js as follows:
backgroundImage: { 'custom-image': "url('/assets/img/custom_image.jpg')" }bg-custom-image in my project, and that did the trick.
I recently used an online converter to transform HTML to JSX code. I visited and pasted the content I had copied from a Tailwind website:
<div class="bg-cover bg-center ..." style="background-image: url(...)"></div>
Afterwards, I copied the newly generated JSX code which looked like this:
style={{ backgroundImage: 'url(/about.jpg.webp)' }}The externalImageUrl variable can contain a link to any image that is hosted online
<div
className="w-full h-48 bg-no-repeat bg-cover"
style={{ backgroundImage: "url(" + externalImageUrl + ")" }}
></div>
While attempting something similar, I encountered the same problem:
<DisplayCard customText="..this is resolved and working" customImage="the-dynamic-image-not-working.jpg"/>
However, making a small adjustment like this solved it:
<DisplayCard customText="..this is resolved and working" customImage="bg-[url('/the-dynamic-image-now-working.jpg')]"/>
...and in the DisplayCard component, I implemented it as follows:
export default function DiaplayCard({customText, customImage}) {
return(
<div
className={`... ${customImage} bg-cover bg-center ...`}
...
/>
...
)}
After some experimentation, I decided to store the fetched URL in a static constant and then use it as the className.
const background = `bg-[url(${fetchedUrl})]`;
Return {
<div className={`${background} ((Other tailwind here))`}>
}
Update: Disregard my previous statement. It seemed to work initially, but only in a test environment with a preset className. The solution didn't persist if I stopped and restarted the batch job.
