Developing a Real-Time Desktop POS with Electron, Angular & WebSockets

Angular 6 ElectronJS WebSocket NodeJS SignalR

At VYND, we created a point-of-sale (POS) and inventory platform for the hospitality industry, requiring sub-second synchronization across multiple concurrent terminal stations.

Key Technical Decisions - Cross-Platform Desktop with Electron & Angular: Packaged Angular 6 within Electron to provide native desktop performance, local file access, and reliable local caching. - Sub-Second Multi-Terminal Synchronization: Implemented real-time bidirectional communication via SignalR / WebSockets to keep order states, pricing updates, and inventory levels synchronized across multiple terminals simultaneously. - Hardware Integration via QZ Tray: Communicated directly with thermal receipt printers, cash drawers, and barcode scanners using QZ Tray drivers. - Full Ownership: Managed the entire development lifecycle from initial requirements and architecture to on-site testing in busy venue environments.
