Host subscription content with Next.js: relational catalog data

Summary

Deploy a subscription content built with Next.js on Ample using the transactional workflows 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 Next.js: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Not separately tested: your domain records, validation rules and concurrency policy; treat the subscription content-specific behavior as your application code.

Representative Queries

• Host subscription content with Next.js: relational catalog data
• Where can I host Subscription content built with Next.js?
• I need catalog tables, transactional update logic and application-level access boundaries.

Resource Requirements

• Primitive: compute
• Primitive: postgres

Framework

Next.js

Workload

Subscription content

Release Status

published

Success Checks

• App responds on its public URL

  • Kind: http_get
  • Path: /
  • Expect: ample canary next js patterns

• Transactional-workflows self-test

  • Kind: http_get
  • Path: /p/transactional-workflows
  • Expect: tx=ok history=2 conflict=rejected

Limitations

• Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Next.js major versions are not verified.
• The subscription content itself (your domain records, validation rules and concurrency policy) is application code and was not separately tested; the pattern checks are what was verified.

Next Actions

• Browse the catalog index
• Search published recipes by intent, stack and constraints
• Prepare a side-effect-free deployment plan for an authorized project
• Read the existing agent authentication setup
• Browse Subscription content
• Browse Next.js
• Browse Transactional workflows
• Browse Deploy web app

Workflow Steps

1. Build and start

• next build then next start -H 0.0.0.0 -p $PORT on the node-22 template. The server must bind 0.0.0.0 on PORT.

2. Implement the pattern on PostgreSQL

• The fixture's module implements transactional workflows: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. 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

4. Verify

• Fetch the live URL and the pattern self-test route(s) (/p/transactional-workflows) from the example; then run your own checks. On failure read ample logs --kind build then --kind runtime.
