Sports clubs: event registration using Next.js

Summary

A event registration blueprint for sports clubs built with Next.js on Ample. Domain schema: course_groups (team_or_class, season, age_group): teams and classes; memberships (course_group_id, member_reference, guardian_reference, role): players, guardians and coaches; sessions (course_group_id, starts_at, venue, type): training and fixtures; materials (course_group_id, title, object_key, visibility): schedules and coaching resources; events (seq, record_type, record_id, kind, at): application-owned history written in the same transaction. Public information: teams, seasons and fixtures, venues, membership fees. Kept out of scope until handling is reviewed: minor members and medical notes, safeguarding records. Medical and safeguarding records are sensitive; only schedules and coaching materials are modeled. Technical basis 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).

Representative Queries

• Sports clubs: event registration using Next.js
• Where can I host Sports clubs: Event registration built with Next.js?
• I need a genuinely specialized event registration workflow covering team membership, event participation and club media.

Resource Requirements

• primitive:compute
• primitive:postgres
• primitive:s3-compatible-object-storage

Infrastructure Requirements

1. Compute
   • Status: verified
   • Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. Postgres
   • Status: verified
   • Summary: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. S3-compatible object storage
   • Status: verified
   • Summary: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Workflow Steps

1. Model the sports clubs domain
   Create the tables course_groups, memberships, sessions, materials, events. Teams and classes lives in course_groups; keep the sensitive classes (minor members and medical notes, safeguarding records) out of this schema.
2. Workflow step 1
   Model sessions with capacity and registrations with status.
3. Workflow step 2
   Register transactionally with a capacity check and an event per registration.
4. Workflow step 3
   Reject stale concurrent updates.
5. Workflow step 4
   Deploy and verify history and conflict handling.
6. Deploy
   Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
7. Verify
   Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the sports clubs workflow.

Limitations

• The technical basis (transactional workflows on Next.js) was verified with the pattern fixture; the sports clubs schema and workflow are an original design for this blueprint and were not executed as a separate application.
• No health, financial, privacy or other compliance claim is made. Medical and safeguarding records are sensitive; only schedules and coaching materials are modeled.
• Public content and synthetic examples only until actual data-handling requirements have been reviewed.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
• Components:
  • App server: s-1vcpu-1gb, 1.0 ($5.0)
  • Managed PostgreSQL database: s-1vcpu-1gb, 1.0 ($5.0)
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

Evidence Summary

• Kind: canary_run
  Summary: Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the transactional workflows checks passed.
