@teincfood/core

TeincFood shared offline-first core — single source of truth for mobile (TeincFoodBusiness) and desktop (TeincFoodDesktop).

What lives here (v0.1.0 backbone)

• types/api/* — snake_case API contracts matching backend
• utils/* — currency, error, format, uuid, order-number (async), etc.
• sync/* — engine, command-queue, transports, routing-policy, pending-orders
• db/* — migrations + operations (driver-agnostic, takes a SqliteDriver)
• reference/* — versioned reference-data cache
• repositories/* — order/pos repositories
• adapters/* — platform seams (KV, SQLite, HTTP, etc.)

Adapters

Apps supply platform adapters via createTeincCore({ storage, db, http, ... }):

• KVStorage — async getItem/setItem/removeItem (MMKV-wrapped on mobile, plugin-store on desktop)
• SqliteDriver — execAsync/runAsync/getFirstAsync/getAllAsync/withTransactionAsync
• HttpClient — axios instance with auth interceptors (token plumbing stays app-side)
• LanTransport — { isAvailable(), execute(command) }

Usage

import { createTeincCore } from "@teincfood/core";
const core = createTeincCore({ storage, db, http });

Apps re-export types via export * from "@teincfood/core" barrels to avoid churn.

Publishing

yarn build
npm publish --access public
