Download Files from Your App

The Keelson CLI does not provide a supported way to place, retrieve, list, or remove files on a running application’s /data disk.

When users need to retrieve generated output, implement a download endpoint in the application. Read the file from the application’s managed data source and return it with appropriate headers, including Content-Type and Content-Disposition: attachment. Keelson’s normal authentication gate applies to regular application routes.

Use Keelson Managed SQLite for durable structured data. If the application stores binaries in an external object store, connect to that service from the application. Do not treat a local file as the only authoritative copy.

Read-only retrieval from the persistence store and Console downloads are post-launch backlog items.
