Atharأثر
Quiet objects.
A considered checkout.A commerce experience for a fictional homeware collection — calm browsing up front, authoritative pricing and orders on the server.
The brief
A store has to carry a visitor from discovering a product to reviewing a consistent order, with clear limits on stock and price.
The approach
Athar separates relaxed browsing from the decisive order calculation, which happens on the server: prices sent by the browser are never accepted as the source of truth. An idempotency key makes a repeated submission return the same order instead of creating a second one.
What you can verify
- Filter the collection and open a product’s details.
- Choose a finish and quantity; quantities are bounded by stock across variants.
- The cart persists in the browser, while totals are recalculated by the server.
- Place a synthetic order; repeating the same request returns the same order.
- Domain and API tests cover quantities, quotes and duplicate submissions.
Implementation & handoff
Product and cart interfaces, a quote and order API, local cart persistence, and tests for quantities and idempotency. Runs on your machine with Node.js 24 and its built-in SQLite — no npm install.
Honest context
Synthetic prices and stock; no payment, shipping or real addresses. Orders are stored locally, and stock is a demonstration check rather than a production inventory reservation. Product images are original generated concept images of fictional items, not goods for sale.
