Learn how Reflex’s persist flag automatically saves component state to localStorage and restores it on page reload, with a worked counter example and notes on limits.
Reflex synchronizes Python state to React via WebSocket deltas. Learn how vars, event handlers, and sub-states work, see a live counter example, and understand the trade-offs of async push-based updates.
A step‑by‑step guide to identify and fix common StimulusReflex problems such as missing triggers, WebSocket failures, and uninitialized constants.
An architectural deep dive into how Reflex synchronizes Python server state with a React frontend using WebSocket deltas to minimize latency and payload size.
Learn how Reflex’s rx.Var and @rx.event enable automatic UI updates from pure Python, with a counter example, WebSocket verification, and notes on memory and mutation pitfalls.
Decide which Reflex state backend— in‑memory, SQLite, or Redis—fits your app’s durability, scalability, and complexity needs. A concise decision guide, comparison table, and hands‑on config example help you pick the right persistence strategy.
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.
Goal We want to display a large list of records in a Rails view using Reflex to update the list via Turbo Streams, while limiting the number of records per page and preserving the current page across multiple Reflex invocations. Constraints Reflex actions are stateless between requests; ActiveRecord scopes can bound a query with limit and offset , but the cl
