Host graphql api with Hono: stored input and output artifacts
Deploy a graphql api built with Hono 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 Hono: 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 graphql api-specific behavior as your application code.

- I need an input/output artifact contract, object metadata and access boundaries.
Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:s3-compatible-object-storage
Infrastructure Requirements
Compute
- Primitive ID: primitive: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.
Postgres
- Primitive ID: primitive: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.
S3-compatible object storage
- Primitive ID: primitive: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.
Workflow Steps
- Build and start: npm install and npm run start with @hono/node-server on the node-22 template. The server must bind 0.0.0.0 on PORT.
- 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). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
- 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 Keep private data in an unpublished bucket.
- 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 --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
- Verify: Fetch the live URL and the pattern self-test route(s) (/p/generated-downloads) from the example; then run your own checks. On failure read
ample logs --kind buildthen--kind runtime.- Command: ample logs --kind build
Examples
Hono pattern fixture
- Description: Multi-pattern Hono app whose generated downloads module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
- Source Reference: tests/deploy-canaries/hono-patterns
Success Checks
- App responds on its public URL: Expecting
ample canary hono patterns - Generated-downloads self-test: Expecting
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 Hono major versions are not verified.
- The graphql api itself (your export formats, retention policy, and entitlement model) 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 verified.
Cost Estimate
- Currency: USD
- Monthly Amount: 10.0
- 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.
- Components:
- App server: s-1vcpu-1gb: $5.0
- Managed PostgreSQL database: s-1vcpu-1gb: $5.0
Evidence Summary
- Kind: canary_run
- Summary: Hono pattern fixture deployed on Ample (npm install and npm run start with @hono/node-server on the node-22 template); checks passed for generated-downloads and configuration-secrets. Pattern proof: 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).
