# Host public directory with Nuxt: object-stored public media

Deploy a public directory built with Nuxt on Ample using the public media library 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, a private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables, and a published bucket serves public assets from the CDN host. Verified on Nuxt: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. Not separately tested: your media processing, object layout, and cache policy; treat the public directory-specific behavior as your application code.

### Representative Queries
- Host public directory with Nuxt: object-stored public media
- Where can I host Public directory built with Nuxt?
- I need an object layout, public asset URL policy, and CDN delivery configuration.

### Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:s3-compatible-object-storage
- primitive:cdn

### Infrastructure Requirements
1. **Compute**  
   Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. **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.
3. **S3-compatible object storage**  
   Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.
4. **CDN**  
   The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

### Prerequisites
- A Nuxt project that builds and starts with the documented commands (nuxt build then node .output/server/index.mjs (reads HOST and PORT) on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env)
- A bucket from `ample bucket create` with its credentials passed as encrypted S3_* environment variables and a second, published bucket for public assets (CDN_*)
- An Ample account token with servers:write, databases:read, buckets:read

### Tested Configuration
- **Template:** node-22  
- **Runtime:** node  
- **Size:** s-1vcpu-1gb  
- **Install:** npm install  
- **Build:** npm run build --if-present  
- **Start:** npm run start

### 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 public media library: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. 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/public-media-library) 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 public media library module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

### Success Checks
1. **App responds on its public URL**  
   - **Kind:** http_get  
   - **Path:** /  
   - **Expect:** ample canary nuxt patterns  
2. **Public-media-library self-test**  
   - **Kind:** http_get  
   - **Path:** /api/p/public-media-library  
   - **Expect:** a CDN URL whose content is served publicly

### 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 media processing, object layout, and cache policy) 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.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs, and lifecycle rules are not.
- The CDN serves published-bucket objects only; cache rules, purge, and TTL control are not verified (the fixture sets Cache-Control on upload and versions keys).

### Cost Estimate
- **Currency:** USD  
- **Monthly Amount:** 10.0  
- **Authoritative:** true  
- **Basis:** size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty  
- **Components:**  
  - **App Server:** s-1vcpu-1gb, Quantity: 1.0, Monthly Amount: 5.0  
  - **Managed PostgreSQL Database:** 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.

### Evidence Summary
1. **Canary Run**:  
   - **Summary:** Nuxt pattern fixture deployed on Ample (nuxt build then node .output/server/index.mjs (reads HOST and PORT) on the node-22 template); checks passed for public-media-library and configuration-secrets. Pattern proof: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly.
