pythonReflex State Desynchronization: Diagnostic Guide for v0.4.x–v0.6.x
When Reflex UI stalls or shows stale values, this guide walks through recognition, ordered checks, and fixes for mutation errors, blocking I/O, WebSocket timeouts and session isolation.
Reflex State Management: Server-Side Event Handlers as the Design Unit
Declare UI state in an rx.State subclass, mutate it only through server-side Reflex event handlers, and validate every browser-supplied value before use.
Managing Reactive State in Reflex: From State Definitions to UI Binding
Learn how to implement reactive state in Reflex by defining State subclasses, creating event handlers, and binding them to UI components for automatic updates.
Reflex's Single‑Source‑of‑Truth State: Why It Works and Where It Drags
Reflex puts all mutable UI state in one Python class on the server, syncing via WebSocket. That eliminates dual‑state bugs but adds latency for high‑frequency interactions. A tiny counter demo shows the flow and how to verify the generated Next.js bundle.
Building a reactive counter in Reflex without JavaScript
How Reflex moves state from Python event handlers to the browser, and why each tab starts with its own counter.
How Reflex’s Built‑In WebSocket Sync Keeps Your UI in Real Time
Reflex’s built‑in WebSocket sync lets you keep multiple browsers in real time without extra infrastructure. Learn how to enable it, test it, and understand its limits in this practical guide.
