Host product catalog with Nuxt: relational catalog data

Deploy a product catalog built with Nuxt on Ample using the transactional workflows 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. Verified on Nuxt: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Not separately tested: your domain records, validation rules, and concurrency policy; treat the product catalog-specific behavior as your application code.

Representative Queries

• Host product catalog with Nuxt: relational catalog data
• Where can I host Product catalog built with Nuxt?
• I need catalog tables, transactional update logic, and application-level access boundaries.

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)
• An Ample account token with servers:write, databases:read

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 transactional workflows: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. 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.
   Command: ample deploy . --name --public

4. Verify
   Fetch the live URL and the pattern self-test route(s) (/api/p/transactional-workflows) from the example; then run your own checks. On failure, read ample logs --kind build then --kind runtime.
   Command: ample logs --kind build

Examples

• Nuxt pattern fixture
  Multi-pattern Nuxt app whose transactional workflows module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

Success Checks

• App responds on its public URL

  • Kind: http_get
  • Path: /
  • Expect: ample canary nuxt patterns

• Transactional-workflows self-test

  • Kind: http_get
  • Path: /api/p/transactional-workflows
  • Expect: tx=ok history=2 conflict=rejected

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 product catalog itself (your domain records, validation rules, and concurrency 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.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
• Components:
  • App server (s-1vcpu-1gb): $5.0
  • Managed PostgreSQL database (s-1vcpu-1gb): $5.0
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

Evidence Summary

• Canary run: Nuxt pattern fixture deployed on Ample; checks passed for transactional-workflows and configuration-secrets.
