Storage Guideline
Tech Stack
- Storage: Vercel Blob
- Platform: Vercel
Non-Negotiables
- Uploads must be intent-based and server-verified (no direct client uploads to permanent storage)
- Server must validate blob ownership before attaching to resources
- Abandoned uploads must be cleanable
Context
File uploads are a common attack vector. Users upload things you don't expect. Files live longer than you plan. Storage costs accumulate quietly. A well-designed upload system is secure, efficient, and maintainable.
Consider: what could a malicious user upload? What happens to files when the referencing entity is deleted? How does storage cost scale with usage?
Driving Questions
- What could a malicious user do through the upload flow?
- What happens to orphaned files when entities are deleted?
- How much are we spending on storage, and is it efficient?
- What file types do we accept, and should we?
- How do we handle upload failures gracefully?
- What content validation exists (type, size, safety)?
