React Query is not a data fetching library, but an Asian state manager. It helps keep data up to date and manage agent life cycles efficiently. React Query provides fine-grained subscriptions and allows for adjusting stale time to control data fetching behavior. Defining stale time and managing dependencies are important aspects of working with React Query. Using the URL as a state manager and Zustand for managing filters in React Query can be powerful.

In this talk, I'll explain React Query from a different perspective. After having maintained React Query for over two years and having answered many questions (often the same ones multiple times), I feel like there might be a fundamental understanding missing about the lib. I'll start with a quick introduction about my journey into open source and how I got to know React Query, followed by showing which mindset change is beneficial when working with React Query - how to "think in React Query". I'll have 3 major takeaways: 1) React Query is not a data fetching library It's an async state manager, we'll quickly talk about what makes a state manager, why React Query is one and what "async state" means. 2) staleTime is your best friend I've seen a bit of confusion about how to use React Query as a state manager, so I'll explain why setting staleTime is mostly all you need 3) parameters are dependencies This is important to understand to show the boundaries between client state and server state, and is essential when doing state management with React Query I will then end with a note on "separation of concerns" and about the tradeoffs of just calling `useQuery` wherever you need it in your component tree.

This talk introduces React Query and Auth, discussing how React Query maintains server state on the client and handles mutations and data updates. The day spa app example demonstrates the use of React Query to fetch data and handle user authentication. React Query is also useful for managing user data and ensuring accurate data from the server. The talk highlights the importance of addressing the three main players in user data: React Query, Auth Functions, and persistence across sessions.

React Query manages server state on the client, and auth manages user sign in/sign up/sign out. Where do these two overlap, and how do you separate concerns? This talk proposes a data flow with custom hooks for both auth and React Query to manage authentication status and user profile updates.

React Query is a popular data synchronization library used by indie developers, startups, and Fortune 500s, with over 1,200 commits and 250 contributors. The Talk covers the creation of a simplified version of React Query called React Query Lite. It explores concepts like caching, background fetching, and garbage collection. The speaker also discusses the use of query observers and the integration of React Query with React. The Talk concludes with a discussion on React Native tools, testing, and the stability of React Query's API.

Since React Summit last year, React Query has already become one of the most popular and powerful data fetching libraries for React. To celebrate, we'll be going behind the scenes to see how React Query actually works and even build our own useQuery hook in just 150 lines of code. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
