Socio is a WebSocket-based full-stack reactive data-binding framework. It eliminates the REST API layer entirely by letting the browser client issue SQL queries (AES-256-GCM encrypted at build time) directly over a persistent duplex WebSocket connection to a SocioServer instance. The server acts as a transactional middleware between the DB and all connected clients — executing queries, then pushing state deltas to all subscribed clients automatically whenever underlying data changes. The client-side SocioClient exposes reactive .query() and .subscribe() primitives, meaning the frontend stays in sync with the DB across all sessions without polling, manual state management, or any handwritten API routes.
