← Part 1: Beyond Chatbots | Series Hub | Next Chapter: Part 3: Component Registry & WebMCP Bridge → Prerequisite: Complete Part 1: Beyond Chatbots and review React 19 Server Components and Astro Islands execution models. Answer-first: State management in Generative UI requires decoupling high-frequency server streaming updates from client user interactions to prevent split-brain race conditions. By pairing React 19 Server Actions and Astro Islands with fine-grained reactive Signals (Nanostores), the architecture achieves sub-2ms DOM node updates, preserves optimistic user input during stream backpressure, and guarantees transactional state reconciliation without full-tree re-renders. ...
