add-files

Set up secure file uploads by configuring a private AWS S3 bucket for storage and delivering files through CloudFront using short-lived signed URLs. This enforces server-side ownership checks and validation without exposing public access.

Yes, you can enforce per-user upload quotas and validate files using magic-byte MIME verification. This prevents file spoofing by checking the file's actual bytes against allowed types and max size limits on the server.

The best way to add private file storage without migrating is to detect and extend your existing storage provider. This approach supports current integrations like R2 or Firebase Storage while enforcing secure ownership checks and signed URL delivery.

Yes, this file upload approach supports practical use cases including folders, tags, image transforms, and versioning. It namespaces files per user to maintain organization while enforcing strict server-side ownership checks on every read and write.

You need magic-byte MIME checks for S3 file uploads to prevent file spoofing and security vulnerabilities. Validating the actual file bytes server-side ensures the uploaded file matches its declared type, blocking malicious payloads from entering your storage.

No, you do not need to migrate files to use CloudFront delivery. The implementation detects your existing storage setup and extends it to support correct signed URL delivery behavior and private bucket defaults without requiring data migration.
