Build a File Upload System With Supabase Storage
Many applications eventually need file uploads. A SaaS platform may need profile images. An ecommerce application may need product photos. A customer portal may need documents. Supabase Storage provides object storage alongside the database.
Do Not Store Large Files in PostgreSQL
Your database is designed for structured data. Images, videos, and documents are better handled by object storage. The database can store metadata such as: File name User ID Storage path File type Upload date
Organize Buckets
Create separate buckets based on your application's needs. For example: avatars documents products attachments
Protect Private Files
Not every file should be public. Private documents should require authorization before they can be accessed. Signed URLs can provide temporary access to protected files.
Connect Files to Users
Store the owner or user ID alongside file metadata. This makes it easier to apply access policies.
Plan for Growth
As file usage grows, think about: Storage capacity Upload size limits File formats Access permissions Image optimization Backup requirements
Hostwares' self-hosted Supabase stack includes Storage with S3-compatible buckets and signed URLs. A clean storage architecture makes future growth much easier.
