CONCURRENT OPTIMISTIC UPDATES IN REACT QUERY

Concurrent optimistic updates in React Query are tough, especially when complex logic or multiple mutations are involved. Optimistic updates can be improved by using query cancellation to prevent inconsistencies from delayed queries. A strategy to prevent over-invalidation after a mutation is by checking if related mutations are already in progress before invalidating, thus avoiding UI flickering.

THE BEST – BUT NOT GOOD – WAY TO LIMIT STRING LENGTH

This deep dive into limiting string length shows the inconsistencies and potential issues arising from different character encoding methods. It goes over various encoding schemes like UTF-8, UTF-16, Unicode code points, and grapheme clusters, showing how their differing length calculations can lead to bugs and poor user experiences across different layers of an application.

Counting by normalized Unicode code points is generally the best approach.
