Deliver public assets through CDN for React Router

Cdn assets for a React Router app on Ample. Verified on React Router: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL. Build and start: react-router build then react-router-serve on the node-22 template.

Summary

Deliver public assets through CDN for React Router.

Representative Queries

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

Resource Requirements

• primitive:compute
• primitive:cdn

Infrastructure Requirements

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

Framework

Workload

Deliver public assets through CDN

Release Status

published

Support Status

verified

Execution Status

ready

Prerequisites

• A React Router project (react-router build then react-router-serve 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

Tested Configuration

• Template: node-22
• Runtime: node
• Size: s-1vcpu-1gb
• Install: npm install
• Build: npm run build --if-present
• Start: npm run start

Workflow Steps

1. Build and start: react-router build then react-router-serve on the node-22 template; 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 /p/versioned-static-assets on the example; on failure read the build and runtime logs. Command: ample logs --kind build

Examples

• React Router pattern fixture: Verified CDN assets on React Router.

Limitations

• Verified on the node-22 template at s-1vcpu-1gb; other sizes and React Router 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: 5.0
• Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
• Components:
  • App Server: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0
• Note: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.
