 ### Where to fetch data
 
-Finding the right place to fetch data in React apps is the million-dollar
+In the past, our approach involved creating separate components for page and
-question, but we decided to make it only in the page components and pass the
+view, where the page component served as a container responsible for fetching
-props down to the views. This makes it easier to find where data is being loaded
+data and passing it down to the view.
-and easy to test using Storybook. So you will see components like `UsersPage`
+
-and `UsersPageView`.
+For instance, when developing a page to display users, we would have a
+`UsersPage` component with a corresponding `UsersPageView`. The `UsersPage`
+would handle API calls, while the `UsersPageView` managed the presentational
+logic.
+
+Over time, however, we encountered challenges with this approach, particularly
+in terms of excessive props drilling. To address this, we opted to fetch data in
+proximity to its usage. Taking the example of displaying users, in the past, if
+we were creating a header component for that page, we would have needed to fetch
+the data in the page component and pass it down through the hierarchy
+(`UsersPage -> UsersPageView -> UsersHeader`). Now, with libraries such as
+`react-query`, data fetching can be performed directly in the `UsersHeader`
+component, allowing UI elements to declare and consume their data-fetching
+dependencies directly, while preventing duplicate server requests
+([more info](https://github.com/TanStack/query/discussions/608#discussioncomment-29735)).
+
+To simplify visual testing of scenarios where components are responsible for
+fetching data, you can easily set the queries' value using `parameters.queries`
+within the component's story.
+
+```tsx
+export const WithQuota: Story = {
+  parameters: {
+    queries: [
+      {
+        key: getWorkspaceQuotaQueryKey(MockUser.username),
+        data: {
+          credits_consumed: 2,
+          budget: 40,
+        },
+      },
+    ],
+  },
+};
