## Overview

This is a CodeIgniter 4 point-of-sale application for managing inventory, customers, cashiers, and transactions, with transaction receipt printing. The documented workflow is a browser request into the public application, route dispatch to a domain controller, and CRUD interaction with the corresponding data model and screens. The README documents MySQL setup and the application’s main features. Several domain controllers and models were not sampled, so their internal calls and view wiring are not asserted; dashed links mark those unverified relationships.

Main entry points: [`app/Config/Routes.php`](https://github.com/dwaryarr/simpleposcrud-ci4/blob/main/app/Config/Routes.php) (POS Routes), [`app/Controllers/Transaksi.php`](https://github.com/dwaryarr/simpleposcrud-ci4/blob/main/app/Controllers/Transaksi.php) (Transaction CRUD), [`app/Controllers/Barang.php`](https://github.com/dwaryarr/simpleposcrud-ci4/blob/main/app/Controllers/Barang.php) (Barang CRUD), [`app/Controllers/Konsumen.php`](https://github.com/dwaryarr/simpleposcrud-ci4/blob/main/app/Controllers/Konsumen.php) (Konsumen CRUD)
