## The short version

A public directory blueprint for property management built with Next.js on Ample. Domain schema: listings (reference, address, unit, rent, publishing_status, agency_id): rental listings with publishing status; agencies (name, license_number, portfolio_size): management offices; maintenance_vendors (name, trade, agency_id, status): vendors per office; reports (agency_id, period, object_key, generated_at): portfolio reports per office; state_transitions (record_type, from_state, to_state): the allowed state machine. Public information: available rentals, office contacts, application process. Kept out of scope until handling is reviewed: tenant identity and payment history, inspection reports with personal data. Tenant data is personal and often regulated; only published listings and office-scoped reporting are modeled. Technical basis verified on Next.js: a workspace-scoped table, an explicit state machine (draft to review to published) that rejects invalid transitions, and a cross-workspace read that returns nothing (transitions=true isolation=true).

## 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.)
- [CDN](/content/discover/primitive/cdn/index.html): verified (A published bucket's objects are served at its public_url. It does not front app compute and is not a cache or key-value store.)

## 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 and a published bucket for public assets (CDN_*)
- A review of which property management data classes may be handled at all; this blueprint models public information only.

## How to do it

1.  Model the property management domain

Create the tables listings, agencies, maintenance_vendors, reports, state_transitions. Rental listings with publishing status lives in listings; keep the sensitive classes (tenant identity and payment history, inspection reports with personal data) out of this schema.

2.  Workflow step 1

Model listings with a publishing_status state machine scoped to the agency.

3.  Workflow step 2

Serve only published listings, with media from the CDN bucket.

4.  Workflow step 3

Enforce the agency scope on every query.

5.  Workflow step 4

Deploy and verify a published listing and that unpublished listings are absent.

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=... --env CDN_PUBLIC_URL=...
   ```

7.  Verify

Run the pattern self-test(s) from the example (/p/relational-records) and your own acceptance checks for the property management workflow.

```
   ample logs <deployment_id> --kind build
   ```

## Tested examples

- **Next.js pattern fixture** (`tests/deploy-canaries/next-js-patterns`): Verified relational records 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)
- relational-records self-test from the example (`/p/relational-records` 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 relational records checks passed: a workspace-scoped table, an explicit state machine (draft to review to published) that rejects invalid transitions, and a cross-workspace read that returns nothing (transitions=true isolation=true). The blueprint's Property management schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
