React Query (TanStack Query) - it is a library that facilitates the management of fetched data, their synchronization, updating and caching, it can be used to manage the state of the server or even the entire application.

In general, this tool can be compared to the Redux library set, but it is much easier to use. It can also be used with other frameworks, e.g. Angular or Svelte. Thanks to React Query, we can easily manage the cache, update the UI optimistically (adding data virtually, before response from the server), handle data loading or errors.
