BrewHaven: A Browser Based Cafe Ordering And Management System

This paper presents BrewHaven, a café ordering and management system built entirely using HTML, CSS, and JavaScript— requiring no server, no database software, and no internet connection. The system consists of two self-contained files: a customer-facing ordering interface and an admin dashboard, both communicating exclusively through the browser\\\'s localStorage API. BrewHaven demonstrates that modern web technologies alone are sufficient to deliver a functional, visually polished digital ordering experience for small cafés. This paper describes the system architecture, design decisions, feature set, limitations, and proposed future enhancements.
