The Vercel Sandbox SDK now includes two new methods that make file retrieval simple.
When you run code in a Vercel Sandbox, that code can generate files like a CSV report, a processed image, or a PDF invoice. These files are created inside isolated VMs, so they need to be retrieved across a network boundary. Until now, this required manual stream handling with custom piping.
If you want to download a generated report from your sandbox to your local machine, you can use
Both methods handle the underlying stream operations automatically. For example, if your sandbox runs a script that generates a chart as a PNG, you can pull it out with a single call to
