## Host public directory with Nuxt: Postgres-backed content

### Summary
Deploy a public directory built with Nuxt on Ample using the relational records pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL, and a published bucket serves public assets from the CDN host. Verified on Nuxt: 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). Not separately tested: your record schema, states and access rules; treat the public directory-specific behavior as your application code.

### Representative Queries
- Host public directory with Nuxt: Postgres-backed content
- Where can I host Public directory built with Nuxt?
- I need a content schema, publishing workflow and cache behavior after content updates.

### Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:cdn

### Infrastructure Requirements
- **Compute**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **Postgres**: 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**: The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

### Workflow Steps
1. **Build and start**  
   `nuxt build then node .output/server/index.mjs (reads HOST and PORT) on the node-22 template. The server must bind 0.0.0.0 on PORT.`

2. **Implement the pattern on PostgreSQL**  
   The fixture's module implements relational records: 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). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. **Wire object storage**  
   Create the bucket(s), then pass endpoint, region, bucket and keys as --env values. Use path-style addressing. Keep private data in an unpublished bucket. Publish only the bucket that serves public assets and reference its CDN URL.

4. **Deploy**  
   Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). Re-running with no change is a no-op.  
   `ample deploy . --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=...`

5. **Verify**  
   Fetch the live URL and the pattern self-test route(s) (/api/p/relational-records) from the example; then run your own checks. On failure read `ample logs  --kind build` then `--kind runtime`.  
   `ample logs  --kind build`

### Examples
- **Nuxt pattern fixture**: Multi-pattern Nuxt app whose relational records module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

### Success Checks
- **App responds on its public URL**  
  `http_get` on `/` should expect `ample canary nuxt patterns`.
- **Relational-records self-test**  
  `http_get` on `/api/p/relational-records` should expect `records=ok transitions=true isolation=true`.

### Limitations
- Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Nuxt major versions are not verified.  
- The public directory itself (your record schema, states and access rules) is application code and was not separately tested; the pattern checks are what was verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.

### Cost Estimate
- **Monthly Amount**: 10.0 USD  
  - **App Server**: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0  
  - **Managed PostgreSQL**: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0

Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.
