I'm currently working on a website using Strapi as a CMS and Next.js (React) in Frontend. The site also has an image slider which obviously contains an image, a headline and a description. I already created a function to get the title and the description, but somehow this doesn't work with the image.
So what do I have to change to display the media in my webpage? The current code looks like the following: (file: /components/image-slider.js):
import React from "react";
const Slider = ({}) => {
const [banners, setBanners] = React.useState(null);
React.useEffect(() => {
const getBanners = async() => {
const res = await fetch("http://localhost:1337/banners/");
const json = await res.json();
setBanners(json);
}
getBanners();
}, [])
if (typeof window !== 'undefined') {
// makes image slider working
}
return (
<div className="img-slider">
<div className="slide active">
<div className="info">
{banners ? banners.filter(function (banner) {
return banner.Title === "Musik"
}).map((banner) =>
<h2 key={banner.Id}>{banner.Title}</h2>
) : (
<div>Loading...</div>
)}
{banners ? banners.filter(function (banner) {
return banner.Title === "Musik"
}).map((banner) =>
<p key={banner.Id}>{banner.Content}</p>
) : (
<div>Loading...</div>
)}
{banners ? banners.filter(function (banner) {
return banner.Title === "Musik"
}).map((banner) =>
<img className="slider-image">{ ? what do I have to put here? / what do I have to change? }</img>
) : (
<div>Loading...</div>
)}
</div>
</div>
<div className="slide">
<div className="info">
{banners ? banners.filter(function (banner) {
return banner.Title === "Sport"
}).map((banner) =>
<h2 key={banner.Id}>{banner.Title}</h2>
) : (
<div>Loading...</div>
)}
{banners ? banners.filter(function (banner) {
return banner.Title === "Sport"
}).map((banner) =>
<p key={banner.Id}>{banner.Content}</p>
) : (
<div>Loading...</div>
)}
</div>
</div>
{/* Futher slides */}
<div className="navigation">
<div className="btn-navig active"></div>
<div className="btn-navig"></div>
<div className="btn-navig"></div>
</div>
</div>
)
}
export default Slider;
... and undernath is the data I get back from the Strapi API looks like the following: (It's just filled with sample images, titles and descriptions...)

I hope someone is able to help me - thank you!
I do not fully understand the problem. I guess you're asking why the pictures are not showing. When the strapi returns, it comes as a path, not as a base url. If you try <img src={http://localhost:1337/ + url} /> I guess the problem will be solved.
