RTK Query is a purpose built data fetching and caching solution for Redux apps, and **can eliminate the need to write _any_ thunks or reducers to manage data fetching**.

 ### Example REST API and Client
 
 To keep the example project isolated but realistic, the initial project setup already includes a fake in-memory REST API for our data (configured using [the Mock Service Worker mock API tool](https://mswjs.io/)). The API uses `/fakeApi` as the base URL for the endpoints, and supports the typical `GET/POST/PUT/DELETE` HTTP methods for `/fakeApi/posts`, `/fakeApi/users`, and `fakeApi/notifications`. It's defined in `src/api/server.js`.

 ## Loading Posts
 
 So far, our `postsSlice` has used some hardcoded sample data as its initial state. We're going to switch that to start with an empty array of posts instead, and then fetch a list of posts from the server.
