createFileResponse

Summary

Creates a file Response with full HTTP semantics including ETags, Last-Modified, conditional requests, and Range support.

Accepts both native File objects and import('@remix-run/lazy-file').LazyFile values. Uses file.type for Content-Type and includes X-Content-Type-Options: nosniff. Uploaded file metadata does not validate the contents. Validate uploaded files before serving them inline, or set Content-Disposition: attachment on the returned response.
