Host Order Tracking with Nuxt: Relational Catalog Data

Deploy an order tracking app built with Nuxt on Ample using the transactional workflows pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, and 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 order tracking-specific behavior as your application code.

Summary

• Workload: Order tracking
• Framework: Nuxt
• Release Status: Published
• Support Status: Verified
• Execution Status: Ready
• Docs Only: false

Representative Queries

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

Prerequisites

1. 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).
2. A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env).
3. An Ample account token with servers:write, databases:read.

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.

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). 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

1. App Responds:
   App responds on its public URL.
   Kind: http_get
   Path: /
   Expect: ample canary nuxt patterns.
2. 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 order tracking itself is application code (your domain records, validation rules, and concurrency policy) and was not separately tested; the pattern checks are 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.

Estimated Cost

• Currency: USD
• Monthly Amount: 10.00
• Components:
  • App server: s-1vcpu-1gb, Quantity: 1, Monthly Amount: 5.00
  • Managed PostgreSQL database: s-1vcpu-1gb, Quantity: 1, Monthly Amount: 5.00
• Note: Always-on monthly price for tested sizes; apps and databases auto-pause when idle.
