What are @firebase/storage's main functionalities?
Upload Files
This feature allows you to upload files to Firebase Storage. The code sample demonstrates how to upload a simple text file to a specified storage reference.
const { getStorage, ref, uploadBytes } = require('@firebase/storage');
const storage = getStorage();
const storageRef = ref(storage, 'some-child');
const file = new Blob(['Hello, world!'], { type: 'text/plain' });
uploadBytes(storageRef, file).then((snapshot) => {
console.log('Uploaded a blob or file!');
});
Download Files
This feature allows you to download files from Firebase Storage. The code sample demonstrates how to get the download URL for a file stored in Firebase Storage.
const { getStorage, ref, getDownloadURL } = require('@firebase/storage');
const storage = getStorage();
const storageRef = ref(storage, 'some-child');
getDownloadURL(storageRef).then((url) => {
console.log('File available at', url);
});
Delete Files
This feature allows you to delete files from Firebase Storage. The code sample demonstrates how to delete a file from a specified storage reference.
const { getStorage, ref, deleteObject } = require('@firebase/storage');
const storage = getStorage();

deleteObject(storageRef).then(() => {
console.log('File deleted successfully');
}).catch((error) => {
console.error('Error deleting file:', error);
});

const { getStorage, ref, listAll } = require('@firebase/storage');
const storage = getStorage();
const listRef = ref(storage, 'some-child');
listAll(listRef).then((res) => {
res.items.forEach((itemRef) => {
console.log('Item:', itemRef.name);
});
}).catch((error) => {
console.error('Error listing files:', error);
});
