Restaurant / POS System (React, Node.js, Stripe, PostgreSQL, WebSocket, Docker) overview

A restaurant point-of-sale and order management system combining React for touchscreen-optimized terminal interfaces and kitchen display screens. Node.js with Express handles order processing, menu management, and real-time kitchen routing via WebSocket connections. Stripe processes card payments and manages tips. PostgreSQL stores menu items, orders, staff schedules, and sales reports. Docker enables consistent deployment across restaurant locations with offline-capable local servers. Targeted at restaurant technology companies building multi-location POS solutions. The tradeoff is the need for robust offline operation during network outages and PCI compliance requirements for payment handling.
