How it works
Calculate handling complexity
Large files, sensitive content, transformations and multiple access roles increase the weighted implementation score.
Generate the safe path
The output sequences client validation, authorized upload, storage, scanning or processing, metadata persistence and user feedback.
Frequently asked questions
Should files pass through the application server?
Often a short-lived signed upload to object storage reduces server load, but authorization and metadata validation must still happen server-side.
Is checking a file extension sufficient?
No. Validate size and allowed type, inspect content where risk warrants it, and never trust a browser-provided filename or MIME type alone.
How should private downloads work?
Keep storage private and authorize each request before issuing a short-lived download URL or streaming the file through a controlled endpoint.
