I am using the following:
const [allImages, setImages] = useState([]);
const getFromFirebase = () => {
//1.
let storageRef = storage.ref(user1);
//2.
storageRef.listAll().then(function (res) {
//3.
res.items.forEach((imageRef) => {
console.log(imageRef);
imageRef.getDownloadURL().then((url) => {
//4.
setImages((allImages) => [...allImages, url]);
});
});
})
.catch(function (error) {
console.log(error);
});
console.log(allImages);
};
and then displaying via:
<button onClick={getFromFirebase}>Show</button><br/><br/>
<div id="photos">
{allImages.map((image) => {
return (
<div key={image} className="image">
<img className="uploadedfile" src={image} alt="" />
<button className="buttondelete" onClick={() => deleteFromFirebase(image)}>
Delete
</button>
</div>
I realise this is returning the getDownloadURL for the image URL, but how do I also return the image filename?
To get the filename you can use getMetadata:
imageRef.getMetadata().then(metadata => {
// do something with metadata.name
});
You can use the 'getMetaData' method.
import { getStorage, ref, getMetadata } from "firebase/storage";
// Create a reference to the file whose metadata we want to retrieve
const storage = getStorage();
const forestRef = ref(storage, 'images/forest.jpg');
// Get metadata properties
getMetadata(forestRef)
.then((metadata) => {
// Metadata now contains the metadata for 'images/forest.jpg'
})
.catch((error) => {
// Uh-oh, an error occurred!
});
You can refer Firebase Docs - File Metadata for a better understanding
