#react query caching

React Query is not a data fetching library, but an Asian state manager. It helps keep data up to date and manage agent life cycles efficiently. React Query provides fine-grained subscriptions and allows for adjusting stale time to control data fetching behavior. Defining stale time and managing dependencies are important aspects of working with React Query. Using the URL as a state manager and Zustand for managing filters in React Query can be powerful.

This talk introduces React Query and Auth, discussing how React Query maintains server state on the client and handles mutations and data updates.
