Host order tracking with Nuxt: authorized file delivery

Summary

Deploy a order tracking 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 order tracking-specific behavior as your application code.

Resource Requirements

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.

Prerequisites

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 stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3).
  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 Keep private data in an unpublished bucket.
  4. Deploy
    Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked).
  5. Verify
    Fetch the live URL and the pattern self-test route(s) (/api/p/generated-downloads) from the example; then run your own checks. On failure read ample logs --kind build then --kind runtime.

Examples

Success Checks

  1. App responds on its public URL
    kind: http_get, path: /, expect: ample canary nuxt patterns
  2. Generated-downloads self-test
    kind: http_get, path: /api/p/generated-downloads, expect: export=ok rows=3 (with ?token=...; 401 without)
