To configure extra native props on a React Upload component, you must ensure they are automatically merged and attached to the outer container div. This guarantees consistent styling and behavior across your application without altering internal component logic.

Handling single and multiple file uploads in React requires configuring event handlers like onAdd, onRemove, and onChange. You also need to review listType, accept, maxSize, and disabled options to manage file selection limits and user interactions properly.

To import the UDesign Upload component without TypeScript types, write standard JS/JSX code and import Upload directly from @ucloud-fe/react-components. This enforces safe usage patterns and avoids requiring external UI libraries for your project setup.

You cannot use external UI libraries alongside the UDesign Upload component. Best practices enforce avoiding them entirely to maintain safe usage patterns, ensuring consistent behavior by relying solely on the @ucloud-fe/react-components package for rendering logic.

Your React file upload configuration ignores custom className attributes because extra native props must be explicitly merged into the outer container. Applying this prop merging pattern ensures your custom styles attach correctly to the outer div element.

Available event handlers for file preview and removal in React upload include onPreview and onRemove. You configure these alongside onChange and onAdd to manage file lifecycle events, ensuring proper user interaction within single or multiple upload scenarios.
