## Overview

This is a Next.js multi-branch POS application. The visible runtime includes a login screen, dashboard pages, REST-style CRUD endpoints for branches, products, transactions, and users, plus Mongoose models and a MongoDB connection helper. The clearest implemented backend flow is an API request handled by a route, which connects to MongoDB and reads or writes its resource model. The README gives no further capability detail, and the sampled POS page is nearly empty; checkout, inventory workflows, and login authentication are therefore not inferred.

Main entry points: [`lib/db.ts`](https://github.com/cwbziscoding/multibrach-pos/blob/main/lib/db.ts) (DB connector), [`app/(dashboard)/login/page.tsx`](https://github.com/cwbziscoding/multibrach-pos/blob/main/app/(dashboard)/login/page.tsx) (Login screen), [`app/api/branches/route.ts`](https://github.com/cwbziscoding/multibrach-pos/blob/main/app/api/branches/route.ts) (Branch collection API), [`app/api/branches/[id]/route.ts`](https://github.com/cwbziscoding/multibrach-pos/blob/main/app/api/branches/%5Bid%5D/route.ts) (Branch item API)
