Host graphql api with Hono: Postgres-backed state
Deploy a graphql api built with Hono on Ample using the durable job state 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 Hono: a jobs table with a state and attempts counter, processing inside a row-locked transaction, and a second run that is a no-op (job=done attempts=1 idempotent=true). Not separately tested: your job types, payload schema and retry policy; treat the graphql api-specific behavior as your application code.
Representative Queries
- Host graphql api with Hono: Postgres-backed state
- Where can I host GraphQL API built with Hono?
- I need a durable state schema and retry/recovery semantics implemented by application code.
Prerequisites
- A Hono project that builds and starts with the documented commands (npm install and npm run start with @hono/node-server 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
- 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 durable job state: a jobs table with a state and attempts counter, processing inside a row-locked transaction, and a second run that is a no-op (job=done attempts=1 idempotent=true). Copy the approach into your schema; keep migrations idempotent and run them with --release-command. - 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.ample deploy . --name --public - Verify
Fetch the live URL and the pattern self-test route(s) (/p/durable-job-state) from the example; then run your own checks. On failure readample logs --kind buildthen--kind runtime.ample logs --kind build
Tested Configuration
- Template: node-22
- Runtime: node
- Size: s-1vcpu-1gb
- Install: npm install
- Build: npm run build --if-present
- Start: npm run start
Success Checks
- App responds on its public URL
Kind: http_get
Path: /
Expect: ample canary hono patterns - Durable-job-state self-test
Kind: http_get
Path: /p/durable-job-state
Expect: job=done attempts=1 idempotent=true
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 job types, payload schema and retry 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:

- 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.
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 durable-job-state and configuration-secrets. Pattern proof: a jobs table with a state and attempts counter, processing inside a row-locked transaction, and a second run that is a no-op (job=done attempts=1 idempotent=true).
