What is @firebase/storage-compat?
The @firebase/storage-compat package is designed for Firebase users who are migrating their projects to the new Modular Web SDK but still need to maintain compatibility with the older Firebase Storage API. It provides a compatibility layer that allows developers to use the Firebase Storage service in a way that's similar to the older 'namespaced' API, while under the hood it uses the modern Modular SDK. This package is particularly useful during the transition period for projects that are being gradually migrated to the new SDK.
What are @firebase/storage-compat's main functionalities?
Upload Files
This feature allows users to upload files to Firebase Storage. The code sample demonstrates how to import the necessary functions from the package, create a reference to a storage location, and then upload a file to that location.
import { getStorage, ref, uploadBytes } from '@firebase/storage-compat';
const storage = getStorage();
const storageRef = ref(storage, 'some-child');
// 'file' comes from the Blob or File API
tuploadBytes(storageRef, file).then((snapshot) => {
console.log('Uploaded a blob or file!');
});
Download Files
This feature enables users to download files from Firebase Storage. The provided code shows how to obtain a reference to a file stored in Firebase and retrieve its download URL.
import { getStorage, ref, getDownloadURL } from '@firebase/storage-compat';
const storage = getStorage();
const pathReference = ref(storage, 'some/child');
getDownloadURL(pathReference)
.then((url) => {
// `url` is the download URL for the file
console.log(url);
});
List Files
This functionality allows users to list all files in a specified directory of Firebase Storage. The code example illustrates how to reference a directory and list all files within it.
import { getStorage, ref, listAll } from '@firebase/storage-compat';
const storage = getStorage();
const listRef = ref(storage, 'files/');
listAll(listRef)
.then((res) => {
res.items.forEach((itemRef) => {
// All the items under listRef.
console.log(itemRef);
});
});
Other packages similar to @firebase/storage-compat
aws-sdk
The AWS SDK for JavaScript provides a similar set of functionalities for Amazon S3, another cloud storage service. While @firebase/storage-compat is specifically tailored for Firebase Storage, aws-sdk offers a broader range of services including but not limited to storage, making it a more versatile choice for projects that use multiple AWS services.
azure-storage
Azure Storage SDK for JavaScript is designed for use with Azure Blob Storage. Similar to @firebase/storage-compat, it allows for uploading, downloading, and listing blobs in storage containers. The main difference lies in the cloud provider, with azure-storage being focused on Microsoft's Azure platform.
@firebase/storage
This is the Cloud Storage component of the Firebase JS SDK.
This package is not intended for direct usage, and should only be used via the officially supported firebase package.
