The type of cloneElement is incorrect. cloneElement(element, props) should accept props object with a subset of properties on element.props. React attributes, such as key and ref, should also be accepted in props, but should not exist on element.props. The "correct" way to model this, then, is with: declare function cloneElement( element: ReactElement, props?: Q & Attributes, ...children: ReactNode[]): ReactElement; However, type inference for Q defaults to {} when intersected with another type. (https://github.com/Microsoft/TypeScript/pull/5738#issuecomment-181904905) And since any object is assignable to {}, we would lose the type safety of the P extends Q constraint. Therefore, the type of props is left as Q, which should work for most cases. If you need to call cloneElement with key or ref, you'll need a type cast: interface ButtonProps { label: string, isDisabled?: boolean; } var element: React.CElement<ButtonProps, Button>; React.cloneElement(element, { label: "label" }); // cloning with optional props requires a cast React.cloneElement(element, <{ isDisabled?: boolean }>{ isDisabled: true }); // cloning with key or ref requires a cast React.cloneElement(element, <React.ClassAttributes<Button>>{ ref: button => button.reset() }); React.cloneElement(element, <{ isDisabled?: boolean } & React.Attributes>{ key: "disabledButton", isDisabled: true }); */ type NativeAnimationEvent = AnimationEvent; type NativeClipboardEvent = ClipboardEvent;
