Part of the Full Stack Developer Roadmap.
Summary
Keeping your frontend's displayed state correctly synchronized with real-time events from the backend — merging live updates into React Query's cache or local state without causing UI glitches.
How to Learn This
- 1Update a React Query cache directly when a real-time event arrives, instead of refetching everything.
- 2Handle out-of-order or duplicate real-time events gracefully.
- 3Test what happens to your UI when the real-time connection briefly drops and reconnects.
