[Firebase Storage](https://firebase.google.com/docs/storage/web/start) is a cloud storage service for Firebase. It allows you to store and serve user-generated content like images, audio, video, and other files. While most of the APIs can be used as you would normally do with Firebase, VueFire exposes a few composables to integrate better with Vue that not only give you access to reactive variables but also to some actions like `upload()` to update a file while keeping the reactive variable up to date at the same time.

These not only give you access to reactive variables, but also to some actions like `upload()` which updates a file while also keeping the reactive variable up to date.

You can upload and monitor the progress of a file upload with the `useStorageFile()` composable. This also exposes the URL of the file once it's uploaded and its metadata, let's start with a full example of a form upload:

To upload and monitor the upload progress of a file, use the `useStorageFile()` composable. This will expose the URL and metadata of the file once it's uploaded. Here's a full example of a form upload:

VueFire also exposes a smaller composable that only retrieves the url of a file. This is useful if you don't need to upload a file but only display it:

To get the download URL for a file, use the `useStorageFileUrl()` composable. This is useful if you **only** need to display a file:

The same way you can access the file URL you can also access the file metadata. You can also use the `update()` function to update the metadata and keep the reactive variable up to date:

To **only**access the file metadata, use the `useStorageFileMetadata()` composable. You can use the `update()` function to keep the metadata and reactive variable up to date:
