Your AI chat works in dev and breaks in prod. Three React lifecycle bugs in LLM streaming — stale closures, lost tokens, background kills — and how to fix them Check more stories related to programming at: https://hackernoon.com/c/programming .

TL;DR: A stream and React are two different lifecycles — fail to sync them and your AI chat breaks silently in prod. Three fixes: (1) Stream Identity — unique ID per stream, every callback checks if it's still current; (2) Explicit Cleanup — close the connection, mark the chat stale, force-fetch on return; (3) Resume, not restart — pick the stream up from a sequence cursor instead of regenerating. Underlying rule: push-based data shouldn't live in React state directly.
