# Host marketplace with Nuxt: authorized file delivery

Deploy a marketplace built with Nuxt on Ample using the generated downloads 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. Verified on Nuxt: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3). Not separately tested: your export formats, retention policy and entitlement model; treat the marketplace-specific behavior as your application code.

## Representative Queries
- Host marketplace with Nuxt: authorized file delivery
- Where can I host Marketplace built with Nuxt?
- I need a file entitlement model and an application-enforced download authorization flow.

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

## 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.  
   [More Info](https://discover/primitive/compute)
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.  
   [More Info](https://discover/primitive/postgres)
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.

## 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 generated downloads: an export query rendered to a CSV artifact. 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.
4. **Deploy**  
   Run the synchronous deploy once and read the result.  
   Command: `ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...`
5. **Verify**  
   Fetch the live URL and the pattern self-test route(s) from the example; then run your own checks.  
   Command: `ample logs --kind build`

## Examples
- **Nuxt pattern fixture**  
   Multi-pattern Nuxt app whose generated downloads module was checked live; the module is under tests/deploy-canaries/_pattern-modules.  
   Source: `tests/deploy-canaries/nuxt-patterns`

## Success Checks
1. App responds on its public URL.  
   Expect: `ample canary nuxt patterns`
2. Generated-downloads self-test.  
   Expect: `export=ok rows=3 (with ?token=...; 401 without)`

## 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 marketplace itself (your export formats, retention policy and entitlement model) is application code and was not separately tested.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.

## Cost Estimate
- **Currency**: USD  
- **Monthly Amount**: 10.0
- **Basis**: Size prices from pricing.toml (loaded by the API)
   - App server: s-1vcpu-1gb, Monthly Amount: 5.0
   - Managed PostgreSQL database: s-1vcpu-1gb, Monthly Amount: 5.0
