$summary A real-time Kanban board is built using Python, JavaScript, and Twilio Sync, leveraging the convenience of a straightforward abstraction using websockets to persist data in a handful of data structures. The application generates access tokens that enable the front end to access the Twilio Sync service from the browser, allowing for multi-client synchronization without deploying microservices or databases. The Kanban board features drag-and-drop functionality, real-time data synchronization across all clients, and can be extended with additional features such as undo/redo, card editing, and a nicer user interface using libraries like Tailwind UI.
