Improve async network state handling with custom React Hooks

React provides flexibility in addressing various app problems, such as state and network management, through custom Hooks. The use of custom React Hooks helps maintain a clean and efficient codebase by decoupling network requests from business logic, allowing for standardized and reproducible patterns. The text outlines the management of network request states—idle, loading, success, and error—and demonstrates how to handle these states using custom Hooks like `usePostsQuery`, `useBetsQuery`, and `useFixturesQuery` with React Query, enhancing testability and modularity. The creation of a small app, Betflix, is detailed, where users can choose sports teams and make predictions, alongside the setup and use of dependencies such as React Query and Netlify Lambda for HTTP requests and serverless functions. Custom Hooks like `useMutationNotification` and `usePlaceBetMutation` are introduced to manage network state changes and user feedback efficiently. The article emphasizes improving user experience through meaningful handling of network state changes and provides resources like the React Query documentation and GitHub repository for further exploration.
