+ +If the data is required as soon as the user lands on the page, such as user authentication status or initial dashboard analytics, it should be fetched from the server state. +This ensures that the page is preloaded with the required data, improving perceived performance and user experience. + +If the data is only needed after a user interacts with the page (e.g., toggling a setting or entering an input), it can be stored in client state to avoid unnecessary API calls. + +### Is the data frequently changing for a single user? + +State that frequently changes in response to user actions (e.g., form inputs, toggles, filters) should be handled as client state to avoid excessive API requests and unnecessary re-renders. + +On the other hand, data that remains relatively static, such as product lists or user profiles, can be fetched from the server state and cached to minimize redundant API calls. + +### Does the data need to persist across page reloads or be globally shared? + +If a piece of state needs to be available across multiple pages or after a user reloads the page, it should be managed as server state. +This ensures that the state is consistent and accessible whenever needed. + +For example, authentication tokens, user settings, and dashboard data should persist across page reloads, making server state the ideal choice. +In contrast, temporary UI interactions like dropdown selections or modals can be handled as client state. + +### Does the state directly impact UI interactivity (e.g., toggles, dropdowns)? + +State that directly affects the UI, such as theme preferences, form inputs, or navigation state, is best managed as client state. +This ensures a smooth and responsive user experience without unnecessary network requests. + +For example, a dark mode toggle should be handled entirely in client state because there is no need to fetch it from the server every time the user interacts with the page. +However, if theme preferences should persist across sessions, the state should be stored in local storage or updated on the server. + +### Does the data require real-time synchronization across multiple clients? + +Some applications, such as collaborative tools or chat applications, require real-time data updates across multiple users. +In such cases, a hybrid approach using client state for local responsiveness and server state for real-time updates via WebSockets or polling is the best approach. + +For instance, a live chat feature can store the currently typed message in client state while fetching new messages from the server state using WebSockets. + +## Hybrid State Management Techniques + +### Server-Side Rendering with Client-Side Hydration + +### Prefetch and Cache Data with React Query + +- Uses background refetching to keep data fresh. +- Reduces redundant requests by caching API responses. + +### Context for Dependency Injection + +## Example + ## Conclusion -Recap -Performance Best Practices +## References
