sommario
Pixie is a collaborative platform for creating pixel art in real time. Multiple users interact simultaneously on the same digital canvas, cooperating on the creation of a shared drawing through an interactive web interface. The application is designed as a Single Page Application (SPA) whose central element is a grid of pixels whose state is kept consistent and updated for all connected clients, enabling a uniform view of the drawing in progress. The system follows a three-tier architecture comprising a Vue.js frontend, a Node.js/Express backend, and a MongoDB database. Real-time synchronisation relies on Socket.IO for bidirectional communication and Server-Sent Events (SSE) for push notifications. To support horizontal scalability and fault tolerance in a distributed deployment, the architecture integrates Redis as a shared state store and pub/sub message broker, Traefik as a load-balancing reverse proxy, and a coordination service that uses distributed locking to safely persist canvas data from any server instance.
