Wholesale distributors: product catalog using Next.js

Summary

A product catalog blueprint for wholesale distributors built with Next.js on Ample. Domain schema:

Public information: catalog with case sizes, minimum order and delivery terms, trade account application. Kept out of scope until handling is reviewed: account pricing tiers, credit terms, delivery addresses. Account-specific pricing and credit terms are confidential; the catalog shown publicly carries list prices only.

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).

Infrastructure Requirements

Primitive ID Label Status Summary
primitive:compute 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.
primitive:postgres Postgres verified Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
primitive:s3-compatible-object-storage S3-compatible object storage verified Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Prerequisites

Workflow Steps

  1. Model the wholesale distributors domain: Create the tables products, stock_movements, orders, order_lines, events. Sku catalog with case sizes lives in products; keep the sensitive classes (account pricing tiers, credit terms, delivery addresses) out of this schema.
  2. Model the SKU catalog with versioned updates.
  3. Record every catalog change as an event in the same transaction.
  4. Reject stale concurrent updates.
  5. Deploy and verify history and conflict handling.
  6. Run the synchronous deploy once and read the result. Command: ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
  7. Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the wholesale distributors workflow. Command: ample logs --kind build

Success Checks

  1. App responds on its public URL.
    • Kind: http_get
    • Path: /
    • Expect: ample canary next js patterns
  2. Transactional-workflows self-test from the example.
