VistasHow to use SimpleImageSlider in Reactjs with an array of images from firebase firestore
I have an array of images saved in my firebase firestore documents. I want to show all images as a slide show and i found this react package that does that, react-simple-image-slider.
My images are saved this way in firestore:
Now I am retrieving them this way in order to add them to the slider:
const [imgUrls, setIMGUrls] = useState([]);
const imageList = []
firebase.firestore().collection("Properties").where("propertyID", "==", propID).get().then((snapshot) => {
snapshot.forEach((doc) => {
const {
imageUrls,
features
} = doc.data();
imageList.push({
imageUrls: imageUrls,
})
setIMGUrls(imageList)
})
})
and using the component this way:
<SimpleImageSlider
width={896}
height={504}
images={imgUrls}
showBullets={true}
showNavs={true}
/>
but I am getting an error that reads
"TypeError: Cannot read properties of undefined (reading 'url')
at SimpleImageSlider"
How can I fix that?
EDIT:
console.log(JSON.stringify(images))

The images property should be array of objects where each object has a property url as mentioned in the usage section. Try refactoring the code as shown below:
const [imgUrls, setIMGUrls] = useState([]);
firebase.firestore().collection("Properties").where("propertyID", "==", propID).get().then((snapshot) => {
// images from all documents in the snapshot
let images = []
snapshot.forEach((doc) => {
const { imageUrls } = doc.data();
images = [...images, ...imageUrls.map(url => ({ url }))]
})
setIMGUrls(images)
})
