 RTK Query has some unique API design aspects and capabilities that are worth considering.
 
 - With React Query and SWR, you usually define your hooks yourself, and you can do that all over the place and on the fly. With RTK Query, you do so in one central place by defining an "API slice" with multiple endpoints ahead of time. This allows for a more tightly integrated model of mutations automatically invalidating/refetching queries on trigger.
-- Because RTK Query dispatches normal Redux actions as requests are processed, all actions are visible in the Redux DevTools. Additionally, every request is automatically is visible to your Redux reducers and can easily update the global application state if necessary ([see example](https://github.com/reduxjs/redux-toolkit/issues/958#issuecomment-809570419)). You can use the endpoint [matcher functionality](./api/created-api/endpoints#matchers) to do additional processing of cache-related actions in your own reducers.

 - Like Redux itself, the main RTK Query functionality is UI-agnostic and can be used with any UI layer
 - You can easily invalidate entities or patch existing query data (via `util.updateQueryData`) from middleware.
 - RTK Query enables [streaming cache updates](./usage/streaming-updates.mdx), such as updating the initial fetched data as messages are received over a websocket, and has built in support for [optimistic updates](./usage/optimistic-updates.mdx) as well.
