5 Tips to Improve User Experience with NgRx
summary
Claims concrete fixes: use NgRx for explicit error handling to avoid infinite spinners (mapToAction in v8 helps), treat the store as a cache plus localStorage to meet RAIL loading targets (5s cold, 2s warm) and show immediate product summaries, and implement optimistic UI for low‑rejection APIs so actions appear instantaneous and revert on failure. Examples include Firebase console notification polling, entity adapters with createEffect/createReducer, and a like button that updates offline then rolls back if the save fails.
