8 Reasons to Use React Query" is likely a presentation discussing the benefits of using the React Query library for managing and caching data in a React application. The slides may cover topics such as efficient data fetching, automatic caching and stale-while-revalidate, real-time updates, and easy-to-use hooks for handling queries and mutations. Additionally, the slides may also highlight how React Query helps improve the performance, developer experience, and user experience of the application.

3. React Query is extremely lean but
packed with battle-hardened
features that will help you succeed in
almost any project. It's a powerful
yet performant data synchronization
tool for React and React Native
applications. It is often described as
the missing data-fetching library for
React, but in more technical terms, it
makes fetching, caching,
synchronizing, and updating server
state in the application all without
touching any global state.
It has a lot of features like Auto Refetching, SSR Support (I could
keep going...), and more features in upcoming slides.

React Query simplifies data-fetching in React by providing
efficient management of network requests, automatic
caching, pagination, and background updates, resulting in
improved performance and user experience.
It also allows for easy control of the data being fetched and
displayed and handling of error and loading states.

React Query mutations provide a simple API for handling
methods (like POST, PUT, DELETE) in addition to querying
data. This allows developers to manage the state of the
application more easily, by providing a consistent way to
update data, without having to manually update the state.
It also provides features for handling optimistic updates,
caching, and error handling for mutations, which can further
simplify the process of making changes to the data.

Optimistic updates in React Query allow for a more seamless
user experience by updating the UI immediately, before
receiving a response from the server. This can make the
application feel faster and more responsive.

refetchInterval
Allows you to set a specific interval in milliseconds between
refetches so that data is refetched automatically after that specific
interval.
refetchOnMount
Allows you to set a specific interval in milliseconds between
refetches so that data is refetched automatically after that specific
interval.
refetchOnWindowFocus
Allows you to set whether the query should be refetched when the
user navigates back to the window/tab where the component is
rendered.
refetchOnReconnect
Allows you to set whether the query should be refetched when the
user's internet connection is restored.
Auto refetching is a feature provided by React Query that
allows for the automatic re-fetching of data based on specific
conditions. This can be useful for keeping data up-to-date
without the need for manual intervention.

be overridden:

Pausing or disabling queries in React Query allows you to
temporarily halt the execution of a query based on certain
conditions, such as user interactions or navigation. This can
improve the performance of your application by avoiding
unnecessary network requests, and also provide a better user
experience by avoiding flicker or loading states when the data is
not needed.
You can pause or disable a query by providing the enabled option
to the useQuery hook.
You can also pause or disable a query by updating the enabled
property of the query after it's created:

React Query provides support for Server-Side Rendering (SSR)
out of the box, which allows you to pre-render your pages on
the server before sending them to the client. This can improve
the performance of your application by reducing the amount of
data that needs to be loaded on the client side.

Infinite scrolling, also known as "endless scrolling" or "infinite
load", is a technique used to load more items as the user scrolls
down the page. React Query provides an easy way to handle
infinite scrolling by providing a simple API for paginating data.
When using React Query with infinite scrolling, you can define a
query that loads a specific page of data, and then use the
fetchMore function to load the next page of data when the user
scrolls to the bottom of the page.
Here is an example of how to implement infinite scrolling with React Query:

isLoading
A boolean value that indicates whether a query is currently being
fetched.
isError
A boolean value that indicates whether a query has failed.
isSuccess
A boolean value that indicates whether a query has succeeded.
isIdle
A boolean value that indicates whether a query is not currently
being fetched.
isFetching
A boolean value that indicates whether a query is currently being
fetched or is in a loading state
isStale
A boolean value that indicates whether the data has been expired
and needs to be refetched.
error
An error object that contains details about the error that occurred
when fetching the query.
React Query provides several built-in indicators to display
background fetching status, which allows you to indicate to
the user that data is being fetched in the background. These
indicators are:
