@lacspace/inventory
Stock-tracking engine that prevents overselling — reserve, release, commit & restock over a plain { onHand, reserved } state. Immutable, bring-your-own-store, throws before it oversells. Isomorphic.
npm i @lacspace/inventoryUsage
import { createStock, reserve, commit, available, InventoryError } from "@lacspace/inventory";
let stock = createStock({ onHand: 10 });
stock = reserve(stock, 2); // checkout hold — THROWS InventoryError before it oversells
stock = commit(stock, 2); // order paid: reserved -> fulfilled
available(stock); // 8 (onHand minus still-reserved)Exports 10
