When to use it
*
Implement File Upload when: - Allowing user media (avatars, docs). - Integrating with cloud storage. - Needing virus scanning. - Building forms with progress bars.
Pros
*
- Centralizes validation (size, type). - Async for non-blocking UX. - Integrates with CDNs. - Resume uploads for large files. - Metadata extraction.
Cons
*
- Security risks (arbitrary code exec). - Storage costs and cleanup. - Bandwidth limits. - Mobile handling quirks. - Scalability for virals.
Notes
Note: Scan with ClamAV. Use signed URLs for direct uploads. Limit to 10MB default.
