File Upload Module

A File Upload Module handles multipart form data, validation, storage (local/S3), and resizing for secure, efficient file handling in web apps.

It often uses libraries like Multer or AWS SDK.

Implement File Upload when:

• Allowing user media (avatars, docs).
• Integrating with cloud storage.
• Needing virus scanning.
• Building forms with progress bars.

Note: Scan with ClamAV.

Use signed URLs for direct uploads.

Limit to 10MB default.
