presentational-container-pattern

To separate data fetching from UI rendering in React, isolate state and data handling in container components or custom hooks, keeping presentational components as pure prop consumers. This reduces coupling and improves reusability for cleaner list and detail screens.

Use the presentational container pattern in React for scenarios with clear data-loading responsibilities where you want UI components to be independent of how data is obtained. It is ideal for building list/detail screens and async data loading flows requiring view purity.

Yes, you can use custom hooks instead of container components for separation of concerns. Custom hooks are encouraged as a modern alternative when they provide the same separation of data fetching and state logic without adding an extra component layer.

Mixing state handling and UI rendering makes React components harder to test because tangled data-fetching and view logic increase coupling. By keeping presentational components pure through prop consumption, you simplify unit testing and enable consistent UI reuse.

The best way to structure React components for async data loading is to create a presentational component that renders UI from props, then implement a container layer or custom hook that fetches data and passes it into the presentational component.
