@munchi_oy/promotion-engine

Pure promotion rule resolution utilities for Munchi channels.

This package is intended to stay headless and reusable across POS, kiosk, storefront, and other consumers. It should not import React, cart-engine, persistence, network clients, or UI code.

Scope

This package will own:

• normalized promotion resolver input and output types
• condition and rule evaluation
• priority and winner resolution
• automatic promotion application plans

This package will not own:

• channel cart state
• cart mutation
• API fetching
• persistence
• activity logs
• UI rendering

Usage

import { resolvePromotions } from "@munchi_oy/promotion-engine";

const result = resolvePromotions({
  promotions: [],
  cart: {
    currency: "EUR",
    subtotalAmount: 0,
    lines: [],
  },
  context: {
    nowIso: new Date().toISOString(),
    timezone: "Europe/Amsterdam",
  },
});
