React Query: Fetch, cache, and update server data using queries and mutations!

In this video we discuss introducing React Query to a ReactJS application. React Query provides a hooks API which allows you to fetch, cache, and update data. At first glance it seems like just a simple library, however you'll find out that it is packed with features which pretty much handle most of the server state management concerns that you might have in any client application. This includes things like automatically de-duping requests, background refreshing, caching, optimistic updating, accessing data globally and several others.

If you make React Query manage your server state, you'll find that the remaining client state that requires management becomes VERY small and likely will remove the need for more complex solutions like Redux. This is state management solution that you absolutely should know about if you're a React developer!
