Learn how to optimize Plotly Dash apps by distinguishing between Input and State to prevent unnecessary server round-trips and improve UI responsiveness.
Learn how Reflex manages full-stack state using pure Python, eliminating the need for JavaScript glue code through centralized state and WebSocket synchronization.
Learn how to diagnose and fix UI lag and state synchronization issues in Reflex by analyzing WebSocket traffic and optimizing state serialization.
Reflex synchronizes frontend UI state with a backend Python State class through a persistent websocket connection managed by FastAPI and Next.js. Event handlers modify backend state, triggering delta serialization and transmission to the browser, where updates trigger reactive re-renders. The framework currently lacks a built-in configuration point to limit
