Deliver public assets through CDN for Nuxt

Summary

Cdn assets for a Nuxt app on Ample. Verified on Nuxt: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL. Build and start: nuxt build then node .output/server/index.mjs (reads HOST and PORT) on the node-22 template.

Representative Queries

• Deliver public assets through CDN for Nuxt
• Where can I host Deliver public assets through CDN built with Nuxt?
• I need a public-origin configuration, versioned asset build and observable cache behavior.

Prerequisites

• A Nuxt project (nuxt build then node .output/server/index.mjs (reads HOST and PORT) 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

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. 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.
   Command: ample bucket publish
3. Verify
   Fetch the live URL and /api/p/versioned-static-assets on the example; on failure read the build and runtime logs.
   Command: ample logs --kind build

Limitations

• Verified on the node-22 template at size s-1vcpu-1gb; other sizes and Nuxt 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

• Currency: USD
• Monthly Amount: $5.00
• Basis: size prices from pricing.toml
• Components:
  • App Server: size s-1vcpu-1gb, Quantity: 1.0, Monthly Amount: $5.00
  • Note: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.

Success Checks

• App responds on its public URL:
  • Kind: http_get, Path: /, Expect: ample canary nuxt patterns
• Versioned-static-assets check from the example:
  • Kind: http_get, Path: /api/p/versioned-static-assets, Expect: see the pattern fixture checks
