S3‑compatible storage for Next.js SaaS
Handle uploads, transforms, and secure delivery with a simple, scalable setup. This starter includes signed uploads, ACL patterns, and URL helpers.
What’s included
- Signed URLs for direct‑to‑bucket uploads
- Server‑side validation of content type and size
- Image processing via on‑the‑fly transforms or jobs
- Access controls and expiring links
Implement in 3 steps
Create buckets per environment; set CORS and lifecycle rules.
Generate short‑lived upload URLs and validate inputs server‑side.
Serve via CDN with signed or public URLs based on visibility.
Use cases
- User content: Avatars, attachments, and media libraries
- Docs & exports: Reports, backups, and data archives
- Product assets: Marketing images and downloadable files
Best practices
- Enforce MIME checks and size limits at the edge or server.
- Store metadata (owner, checksum) alongside objects for audits.
- Use least‑privilege IAM and rotate keys regularly.
Avoid embedding secrets in client uploads. Use server‑generated, short‑lived credentials and validate after upload.
Architecture
- Public vs. private buckets with separate policies
- Direct‑to‑storage uploads with server‑generated signatures
- Async processing (thumbnails, transcripts) via background jobs
Security & compliance
- Enforce least‑privilege IAM per environment and service.
- Encrypt at rest and in transit; enable bucket versioning where needed.
- Implement deletion policies that comply with user data requests.
Caching & CDN
- Set Cache‑Control and ETag headers; leverage immutable asset URLs.
- Serve through a CDN and purge on update for dynamic assets.
- Use image optimization at the edge where possible.
Observability & cost
- Track egress, storage size, and operation counts per bucket.
- Alert on sudden spikes to prevent unexpected bills.
- Log upload failures and rejected MIME types for debugging.
Data lifecycle
- Lifecycle rules for archival and automatic expiration.
- Migrate old formats or sizes as requirements evolve.
- Periodic integrity checks using checksums.
