@lacspace/inventory
Headless stock engine that prevents overselling — reserve/commit/restock over plain { onHand, reserved } state, plus multi-location transfers, reorder points, lot/expiry FIFO-FEFO allocation, and an append-only movements ledger with low-stock & expiring-soon reports. Immutable, bring-your-own-store, 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
