Direct-to-consumer brands: inventory manager using Next.js

Summary

A inventory manager 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.
• A history query over the application-owned events (history=2 conflict=rejected).

Representative Queries

• Direct-to-consumer brands: inventory manager using Next.js
• Where can I host Direct-to-consumer brands: Inventory manager built with Next.js?
• I need a genuinely specialized inventory manager 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.

Prerequisites

1. A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)
2. A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
3. Bucket credentials from ample bucket create passed as encrypted S3_* environment variables
4. A review of which direct-to-consumer brands data classes may be handled at all; this blueprint models public information only.

Workflow Steps

1. Model the direct-to-consumer brands domain: Create the tables products, stock_movements, orders, order_lines, events. Sensitive classes (customer contact and payment details, discount codes tied to individuals) kept out of this schema.
2. Workflow step 1: Model SKUs and stock movements; derive stock from movements.
3. Workflow step 2: Apply movements transactionally with an optimistic version check on the SKU.
4. Workflow step 3: Record an event per movement for history.
5. Workflow step 4: Deploy and verify history and rejected stale updates.
6. Deploy: 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. Verify: Run the pattern self-test(s) from the example and your own acceptance checks for the direct-to-consumer brands workflow.
   • Command: ample logs --kind build

Success Checks

• App responds on its public URL
  • Kind: http_get
  • Path: /
  • Expect: ample canary next js patterns
• Transactional-workflows self-test from the example
  • Kind: http_get
  • Path: /p/transactional-workflows
  • Expect: see the pattern fixture checks

Limitations

• The technical basis was verified; the direct-to-consumer brands schema and workflow are an original design.
• No health, financial, privacy or other compliance claim is made.
• Verified on the node-22 template at s-1vcpu-1gb; other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and other procedures are not verified.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Components:
  • App server: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0
  • Managed PostgreSQL database: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0
  • Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

Evidence Summary

• A Next.js pattern fixture deployed on Ample; the transactional workflows checks passed; the blueprint's schema and workflow build on that verified basis.
