App Storage

App Storage is Replit’s built-in object storage that lets your app easily host and save uploads like images, videos, and documents. Buckets are containers for storing objects such as files. They include access policies to limit what actions users or applications can perform on their contents. With App Storage, you can build apps like:

• Photo sharing platforms: Let builders upload, store, and display images
• Video streaming services: Handle video uploads and serve content to viewers
• Document management systems: Store and organize builder files with secure access
• Portfolio sites: Showcase work with media files that load reliably
• File backup services: Provide builders with cloud storage for their important files

The App Storage tool lets you seamlessly share data between your development and production environments or with other Replit Apps.

​

App Storage provides the following features for your Replit Apps:

• Persistent cloud storage: Store files that remain accessible to your published app and users

How to access the App Storage tool

To associate a new storage bucket with your Replit App, create a bucket.

How to create a bucket

The following sections explain the bucket and object management options in the App Storage tool.

​

Select a bucket

To switch between your storage buckets, select the dropdown menu in the top left corner of the App Storage tab. The selected bucket displays a check mark next to its name, as shown in the screenshot below:

​

Access the bucket ID

To view the Bucket ID by selecting the Settings view from the dropdown at the top of the App Storage tab. The Bucket ID uniquely identifies the bucket, which your code must reference to perform an operation. If you have multiple buckets, select the correct bucket from the dropdown menu in the top left corner. The following screenshot shows the Bucket ID for the “FileVault Bucket One” bucket:

​

Upload or download objects

To upload an object to the selected bucket:

1. Navigate to the Objects view in the App Storage tab.
2. Select Upload files, or Upload folder to upload all files from a folder. Then, select one or more files to upload from the file dialog. Alternatively, drag a file or folder into the area that lists the contents of the bucket.

To download an object from the selected bucket:

1. Navigate to the Objects view in the App Storage tab.
2. Select the download icon to the right of the file to download it.

​

Organize objects in folders

To create a folder in the selected bucket:

1. Navigate to the Objects view in the App Storage tab.
2. Select Create Folder in the Objects view.
3. Enter a name for the folder.

To add objects to a folder in the Objects view, drag an object to the destination folder. To move the object to a parent folder, drag it above the header to the name of the folder above the object list. The following animation shows moving the “product_demo.mov” file from the “videos” folder to the parent “Objects” folder:

​

Delete objects or buckets

To delete an object forever:

1. Navigate to the Objects view in the App Storage tab.
2. Select the trash icon next to the object you want to delete.
3. Confirm the deletion in the confirmation dialog.

To delete a bucket and all the objects it contains:

1. Navigate to the Settings view in the App Storage tab.

Bucket access management

Replit connects all buckets you create to your account and makes them available to all your Replit Apps. The Replit App from which you create the bucket automatically receives access. You can control which of your Replit Apps have access to a specific bucket, which lets you share data efficiently and securely. To grant your Replit App access to a bucket from another app on your account:

1. Select Add an existing bucket from the bucket menu at the top left of the App Storage tab.
2. In the Choose a Bucket dialog, choose the bucket you want to add and select Add Bucket to Repl.

To revoke your Replit App’s access to a bucket:

1. Navigate to the Settings view in the App Storage tab.
2. From the bucket dropdown in the top left of the tab, select the bucket name.
3. Select Remove Bucket from Repl and confirm removal in the confirmation dialog.
