[anubrag]

The goal of this feature request is to integrate SQLSync into the Nextpy framework. SQLSync is a collaborative, offline-first wrapper around SQLite, aimed at synchronizing web application state across various users, devices, and the edge. The integration of SQLSync will enable Nextpy to efficiently manage application state in a distributed environment, enhancing its capabilities in terms of data consistency, offline functionality, and real-time collaboration.
