Direct-to-consumer brands: product catalog using Next.js

A product catalog blueprint for direct-to-consumer brands built with Next.js on Ample. Domain schema: products (sku, name, collection, price, active): product catalog; stock_movements (sku, warehouse, delta, reason, moved_at): fulfillment stock; orders (order_no, channel, status, placed_at): orders with status transitions; order_lines (order_no, sku, qty, unit_price): order contents; events (seq, record_type, record_id, kind, at): application-owned history written in the same transaction. Public information: product catalog and collections, shipping and returns policy, brand story. Kept out of scope until handling is reviewed: customer contact and payment details, discount codes tied to individuals. Checkout and payment are handled by your commerce provider; only catalog, stock and order status are modeled here. 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

• Direct-to-consumer brands: product catalog using Next.js
• Where can I host Direct-to-consumer brands: Product catalog built with Next.js?
• I need a genuinely specialized product catalog workflow covering product variants, branded media and fulfillment-state handling.

Resource Requirements

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

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.
• Postgres: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
• S3-compatible object storage: 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 direct-to-consumer brands domain - Create the tables products, stock_movements, orders, order_lines, events. Product catalog lives in products; keep the sensitive classes (customer contact and payment details, discount codes tied to individuals) 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. Re-running with no change is a no-op.
7. Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the direct-to-consumer brands workflow.

Examples

• Next.js pattern fixture: Verified transactional workflows basis for this blueprint.

Limitations

• The technical basis (transactional workflows on Next.js) was verified with the pattern fixture; the direct-to-consumer brands 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. Checkout and payment are handled by your commerce provider; only catalog, stock, and order status are modeled here.
• Verified on the node-22 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Components:
  • app server (s-1vcpu-1gb): $5.0
  • managed PostgreSQL database (s-1vcpu-1gb): $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. The transactional workflows checks passed: 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).
