React Query Mastery
Async cache sounds simple, but it can play tricks on developers: a page that's slow to load, pagination that takes too long to come back, an infinite scroll that stutters, a dashboard that gets too heavy for the server to keep up with, and a refresh the user has to trigger manually just to see updated data. This demo will try to make each of these problems concrete, explaining the concept behind it and how it gets solved.
