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. Link to heading Download a file If you want to download a generated report from your sandbox to your local machine, you can use downloadFile() to seamlessly stream the contents. const dstPath = await sandbox . downloadFile ( { path : 'generated-file.csv' , cwd : '/vercel/sandbox' } , { path : 'generated-file.csv' , cwd : '/tmp' } ) ; Link to heading Read file contents to buffer 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 readFileToBuffer() , no manual stream wiring needed.…
