# Host marketplace with Nuxt: inventory imports

## Summary
Deploy a marketplace built with Nuxt on Ample using the bulk import staging 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: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Not separately tested: your import format, mapping and conflict rules; treat the marketplace-specific behavior as your application code.

## Representative Queries
- Host marketplace with Nuxt: inventory imports
- Where can I host Marketplace built with Nuxt?
- I need an inventory import contract, staging objects and row-level error handling.

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

## Infrastructure Requirements
1. **Compute**
   - Status: verified  
   - Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.  
   - [More details](/discover/primitive/compute)

2. **Postgres**
   - Status: verified  
   - Summary: 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 details](/discover/primitive/postgres)

3. **S3-compatible object storage**  
   - Status: verified  
   - Summary: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.  
   - [More details](/discover/primitive/s3-compatible-object-storage)

## 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  
- 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**  
   Command: `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**  
   Body: The fixture's module implements bulk import staging: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. **Wire object storage**  
   Body: 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.

4. **Deploy**  
   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**  
   Command: `ample logs  --kind build`  
   Body: Fetch the live URL and the pattern self-test route(s) (/api/p/bulk-import-staging) from the example; then run your own checks. On failure read `ample logs  --kind build` then `--kind runtime`.

## Examples
1. **Nuxt pattern fixture**  
   Description: Multi-pattern Nuxt app whose bulk import staging 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**  
   Kind: http_get  
   Path: `/`  
   Expect: `ample canary nuxt patterns`

2. **Bulk-import-staging self-test**  
   Kind: http_get  
   Path: `/api/p/bulk-import-staging`  
   Expect: `imported=2 rejected=1 restart=ok`

## 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 import format, mapping and conflict 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.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not.

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

     - 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.
