📦 How to get the code?

This is package is one line of code, so you can either install it or copy-paste it 😉

🔌 Installation

yarn add --dev props-of

📃 Source

export type PropsOf<T> = T extends React.ComponentType<infer P> ? P : never;

❔ Why

And now we can use it for props of parent component.

type MenuLinkProps = {
  to: LinkProps['to'];
} & PropsOf<typeof Menu.Item>;

const MenuLink = ({ children, to, ...rest }: MenuLinkProps) => (
  <Menu.Item {...rest}>
    <Link to={to}>{children}</Link>
  </Menu.Item>
);
