Developing a Real-time Dashboard with Flask, Postgres, and Socket.IO

This tutorial guides developers through building a real-time inventory dashboard where database changes appear instantly on users' screens. Using Flask, PostgreSQL's LISTEN/NOTIFY feature, and Socket.IO WebSockets, the project streams data updates without requiring page refreshes. The complete implementation includes a RESTful API, database triggers, threading for notifications, and a responsive frontend that updates dynamically when inventory items are created, modified, or deleted.
