Deliver public assets through CDN for Hono

Summary

Cdn assets for a Hono app on Ample. Verified on Hono: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL. Build and start: npm install and npm run start with @hono/node-server on the node-22 template.

Infrastructure requirements

• Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
• CDN: verified (The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.)

Prerequisites

• A Hono project (npm install and npm run start with @hono/node-server on the node-22 template)
• A bucket from ample bucket create with credentials passed as encrypted S3_* environment variables
• An Ample account token with servers:write, buckets:read

Exact tested configuration

• template: node-22
• runtime: node
• size: s-1vcpu-1gb
• install: npm install
• build: npm run build --if-present
• start: npm run start

Steps

1. 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.

2. Publish a bucket for public assets. Publish only the asset bucket; upload versioned keys with an immutable Cache-Control header and build URLs from its public URL.

   ample bucket publish <bucket-name>
   

3. Verify. Fetch the live URL and /p/versioned-static-assets on the example; on failure read the build and runtime logs.

   ample logs <deployment_id> --kind build
   

Tested examples

• Hono pattern fixture (tests/deploy-canaries/hono-patterns): Verified CDN assets on Hono.

Success checks

• app responds on its public URL (/ on the live URL, expect ample canary hono patterns)
• versioned-static-assets check from the example (/p/versioned-static-assets on the live URL, expect see the pattern fixture checks)

Limitations

• Verified on the node-22 template at s-1vcpu-1gb; other sizes and Hono major versions are not verified.
• Region, compliance attestations and request-duration limits are unknown and not claimed.
• The CDN serves published-bucket objects only; cache rules, purge and TTL control are not verified.

Cost estimate

Estimated 5.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

• app server x1 s-1vcpu-1gb: 5.00 USD

Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.
