## The short version

An asset library blueprint for photography studios built with Next.js on Ample. Domain schema: listings (reference, session_type, price_from, publishing_status, agency_id): session packages with publishing status; agencies (name, location, studio_count): studios or locations; galleries (listing_id, object_key, cdn_key, consent_reference): published portfolio media; reports (agency_id, period, object_key, generated_at): studio booking reports; uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner. Public information: session packages and pricing from, consented portfolio galleries, studio locations. Kept out of scope until handling is reviewed: client galleries before release, minors in photographs, payment details. Client galleries are private until released with consent; only consented portfolio media is public. Technical basis verified on Next.js: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok).

## What it needs

- [Compute](/content/discover/primitive/compute/index.html): verified (Apps run in isolated x86_64 Firecracker microVMs; sizes are the priced VM sizes.)
- [Postgres](/content/discover/primitive/postgres/index.html): verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)
- [S3-compatible object storage](/content/discover/primitive/s3-compatible-object-storage/index.html): verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

## Before you start

- A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
- Bucket credentials from `ample bucket create` passed as encrypted S3_* environment variables
- A review of which photography studios data classes may be handled at all; this blueprint models public information only

## How to do it

1. **Model the photography studios domain**  
   Create the tables listings, agencies, galleries, reports, uploads. Session packages with publishing status lives in listings; keep the sensitive classes (client galleries before release, minors in photographs, payment details) out of this schema.

2. **Workflow step 1**  
   Model assets linked to their owning group or workspace

3. **Workflow step 2**  
   Validate uploads and store them in the private bucket; link each object to its row

4. **Workflow step 3**  
   Authorize downloads by membership

5. **Workflow step 4**  
   Deploy and verify rejection of disallowed files and a linked upload

6. **Deploy**  
   Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
   
   ```
   ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
   ```

7. **Verify**  
   Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the photography studios workflow.
   
   ```
   ample logs <deployment_id> --kind build
   ```

## Tested examples

- **Next.js pattern fixture** (`tests/deploy-canaries/next-js-patterns`): Verified browser file uploads basis for this blueprint.

## How to know it worked

- app responds on its public URL (`/` on the live URL, expect ample canary next js patterns)
- browser-file-uploads self-test from the example (`/p/browser-file-uploads` on the live URL, expect see the pattern fixture checks)

## Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision ca0b484a7a9957c573a88d3a32dc603c3c10135a).

- app server x1 `s-1vcpu-1gb`: 5.00 USD
- managed PostgreSQL database x1 `s-1vcpu-1gb`: 5.00 USD

Upper-bound monthly price of the tested sizes. Buckets are allocation-priced per quota and not included.

## Verification evidence

- canary_run on 2026-09-21T02:34:39Z at revision `1d28ae0 (CLI 0.1.21)`: Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the browser file uploads checks passed: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok). The blueprint's Photography studios schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
